Pros: I did a lot of reading on water cooling before I took the jump. I build a custom system and it would have cost 500 dollars more than this. Reading reviews about this system, Thanks Google, I decided to go with this and is not been a disappointment!

Cons: Hosing is VERY stiff. Also I dislike using distilled water. I suggest Feser One - F1 - Cooling Fluid. Its not water so no Chance of frying your sys. (I poured this stuff on my old computer and even leaked in the AGP slot, cpu socked, ect. Didn't shut down and fine. :)

Other Thoughts: Great system! its awesome!

Pros: *works flawlessly.
*powerful pumps.
*cools down vga and cpu 22 celcius.

Cons: *tubing is stiff. I recommend danger dens tubing its veryflexible.

Other Thoughts: coolermaster stacker 830, amd phenomx4 II 955 , 2 ati crossfire 3870 (waiting on 5870's ^^). danger den Low Profile MAZE5-GPU .

Pros: Hello, i recently purchased this and thought i would do a review.. its to start VERY nice. im 15, and have a HAF 932 case and bought this for internally mounting and everything fit perfectly. not bad for 1st time eh?

e8400 @ 3.0 (stock speed) 30c-40c
e8400 @ 4.0 (oc'ed) 37C-45C

no leaks, takes alot of work to install, put some blue Neon cathodes in there for a nice glow

Cons: kinda lacks in the waterblock area
:(
if i had the money i would go with an apogee gtz :)
BUT
decent temps

Other Thoughts: none

Pros: Nice compact water cooling unit. Comes with all 3/8 in. tubing. Kept my Q9550 OC'd @ 3.40GHz at a constant 35C idle and no higher than about 45C-50C max load with OCZ Freeze Thermal Compound. The flow meter built into the reservoir is also cool. Great green lighting inside. The pump actually can handle the CPU block, the 240mm Radiator and my NB/SB block and another 120mm Radiator with no issue. The radiator that comes with this kit will fit inside a Cooler Master HAF 932 Case. The screw holes on the radiator line up with the holes on the top of the case.

Cons: The fittings are compression type fittings, but they are not the best. They feel really light and flimsy. The tubing is also not really good. Super stiff tubing. Dont expect to angle well with it. I ended up using some Tygon tubing instead. The coolant is also not that great. Not premixed or UV reactive either. And my system leaked from the housing. But i took it apart and fixed it, put better clamps on the tubing. Also i could not get the ESA Software to work with my 780i SLI motherboard. Used the software from nVidia's website. And The fans on the radiator are way too loud!

Other Thoughts: Not a bad starter kit for someone jjust starting water cooling. Just be sure to use better tubing. Id probably recommend a custom kit instead of this.

Pros: I've had this liquid cooling system for almost 4 months now and I havn't had any leaks or any problems with the pump or radiator. The water block, connectors, screws are all this working perfectly. Havn't had to add any extra coolant yet. Got it hooked up to my Q9650 OC'd to 4.05 Ghz with a FSB of 1800 Mhz and my ASUS Striker II Extreme. Getting 30C - 46C max on the CPU and 31C - 54C max on the MCP of the 790. They provide you with plenty of tubing. Still have some left. The ESA feature with the Nvidia control panel is cool, read temps & fan speeds.

Cons: One of the temp. sensors went bad and is reading over 1300C when it's clearly at room temperature, since it hasn't burst into flames. The tubing is stiff. A couple of the LEDs on the radiator burnt out or shorted our, not exactly sure why they stopped working. Didn't have enough coolant in the kit to fill the reservoir.

Other Thoughts: This system isn't very noisy, it seems pretty quiet compared to my 3 GTX280's. The Nforce 7 series chipsets are notorious for getting hot. My 780 used to get up to 76C with tri SLI and it never got over 54 C with this system. Same now with my 790 ultra, never used air cooling with it but seeing from 31 - 54 C max. with Tri SLI. Not bad. With one sinlge GPU card you could cool your whole system with this liquid cooler. The CPU, The board, the RAM and the GPU. Says it's good for up to 600 watts of heat dissipation. Seems accurate. So there it is. The facts from somebody who's had one for several months. Mine is awesome. Made life much easier for me and potencially less expensive, given the loss in heat for my gear.

Pros: Cooler Master has done a great job at setting up a water cooler. Designed exactly for my Cosmos 1000 case. Runs great, no leaks, no problems what so ever. And to what I have read about people having problems with the o-rings, on the model I recieved it had metal o-rings instead of rubber. The hose was alittle tight getting it on there but after it was on and the screw was tightened over it, it made a sug fit. Works great with ESA for nvidia bords, but I had to sacrifice a usb connector for it. Also it lower my temps from abot 50c to 35c when running idle. And that was switching from a zalman copper air cooler.

Cons: Water level on nvidia system monitor says it is 85% full when it is full. Was not a copper waterblock. Lost a usb connection when hooking up to use esa support.

Other Thoughts: Would have ran the whole system with water cooling, but it would have cost $600 more to get all the parts. Right now I just have the standard hook-up, with just the cpu. Going to buy the water blocks for the 9800gx2's soon. Also I would like to buy 2 more radiators to replace where the fans sit when i get the water blocks for the video cards.

System spec's Cosmos case 1000, xfx 780i sli mobo, 8gigs ddr2 800 ram, 2 terabytes of hard drive space, core 2 quad q9550 2.8ghz, 2 9800gx2's in quad sli, and the newest addon is the cooler master water cooler.

Pros: Comes with plenty of hose. Decent fittings. Overall a "potentially" nice system.

My AMD Quad Core runs around 42'C running in full-power mode playing Left 4 Dead using multi-core rendoring.

I think this system could easily cool my whole system if I bought the plumbing for it.

Uses the nVidia ESA control panel to view stats.

Cons: This product has serious quality issues. MOST IMPORTANT: the CPU block came from the factory missing the O-Rings on the fittings. Thus, the CPU block leaked out of the box. Cooler-Master Tech support was quick to send me another one that I'm guessing was used because some of the screws in the block were incompletely threaded and their phillips heads were slightly stripped.

Because I ended up replacing the radiator fittings with quick-connects, I had 2 spares anyway. (GET QUICK CONNECTS! -- See below)

Also, the front bezel that's "chrome plated plastic" shows signs of abrasion.

It's in the system and is running fine now that the leak is fixed.

I would not buy another one until they fix their quality-control. Wait until someone has better things to say about it.

Other Thoughts: The fittings on the system are NPT 1/4" fittings. You can get quick-connects online. Well worth the cost. (about $50 in fittings) It saved my bacon for my installation.

Also buy a bag of 90' bend fittings. They'll help save stress on the tubing causing kinks. Look for 3/8" I.D. barbed fittings. Make sure to use hose clamps.

Otherwise, more tech info would be nice. I wouldn't mind putting in a few more temp settings.

Pros: This liquid cooling system works pretty well. With my Core 2 Q9650 OC'd to 4.0 Ghz with a FSB of 1780 mhz air cooled with an aftermarket copper heat pipe heat sync with 120mm fan I used to get temps of 50 C under load and around 40 C idle, Now with this liquid cooling system using the water block and heat sync compound that came with it I'm getting 36 C under load and around 30 C idle. Depending on the temp in the room I've seen temps as low as 12 C on 2 cores and 25 C on the other 2 cores. And as an added bonus it helps keep all the other components in my case cooler. I've noticed a significcant drop in temps on all of my other gear, the 780i mobo, and all 3 of my GTX280's.

Cons: Difficult to fit in your case. I have a Cooler Master Stacker 830 case which is a full tower case with tons of space and there really was only 1 spot I could fit this radiator in this case and that was in the top, I had to pull the top of my tower off and remove the fan fixture in the top and also the alluminum tabs that held in it place, I didn't cut them, I just bent them back in case I ever needed to use them again. Then I used zip strips to hold it in place which worked fine, If I wanted to do a professional job I would have drilled holes and tapped them out to screw it in place, but I spent 9 hours doing it this way to make it perfect using my method. Then I placed the 120mm fan I took out to fit the radiator back in above it to blow the heat straight out the top of my case. Stiff tubing wanted to kink but I heated it with my lighter if I needed to bend it a little and that kept it from kinking. Also, not enough liquid coolant in the kit, buy at least 1 more bottle.

Other Thoughts: I was a little wary about using the heat sync that came in this kit but it surpassed my expectations, I was also wondering about the radiator whether it would work well enough or whether I sould get a bigger one, but it works pretty good and it looks cool all lit up in green LEDs. The base unit has a clear plastic bubble in the front to view your coolant level and a flow meter right next to it so you can see that your pump is working. It comes with 2 sensors that sense temp which dictates the speed of the pump and it's ESA compatible so you're supposed to be able to control it but I havn't tried yet. Overpowers my blue LEDs with green, which doesn't really bother me. Overall I'm happy, it does what I wanted it to do, so it definitely is highly recommended by me to people who have skill enough to build and mod systems, otherwise, get some help. This was the most difficult task I've ever undertaken since the beginning of my computer building days. Very tedious.

Pros: Looks good.

Cons: The first system had a catastrophic resevoir leak. I doused my mobo and vid card. I RMA's it and got a replacement. The second one leaked as well, but not as catastrophic as the first one. They both leaked from the *bottom* of the resevoir. This shows that it was not my fault, but a manufacturing error. This was my worst experience with newegg products. Luckily, I got a refund even though it was past the 30 day return window. I applaud newegg customer service.

Pros: lowered temps 10 deg. looks nice.

Cons: would have been easy install but fan wiring was about 6 inches to short. so had to splice them. other than that slips right in Kandalf lcs. Nvidia software not completly working on L1n64-sli. 680a chipset. Temps shown in other thoughts were taken under heavy load.

Pros: Ok, I have had this cooler for about 2 months now, and it has not let me down. The pump in this thing is just amazing. I have 2 major kinks in the hoses and the pump just keeps pushing through them. The fans are quiet and keeps my proccessor cooler than I thought it would. I have the radiator mounted to the top of my case blowing the hot air out, which also helped to lower my case temp drammatically. I have an EVGA 9800GX2, which in my old setup, hit 80c when idle and 95c while playing Crysis. now it idles at 45c and only hits 60c at max. I love the green coolors but with my entire case lit up with 8 green fans, it looks a little clear. note that the light behind the fluild resorvoir is not green but clear, so if you get a different coolored fluid, just change the fans to your desired color. decent waterblock. Ohh, and keeps CPU at a nice 30c on idle, before I OCed. And you must get AS 5 to go with it, just a small rice sized peice and don't rub it around, push the block straight down.

Cons: It is very big, and was a tight fit with my case but works flawlessly now that it is in there. Fans are worthless, not loud, but don't move enough air, and are a little dim. Does not leak, but highly reccommend filling/building/testing outside of your case before putting it in an expensive computer. Also reccommend a full tower, it won't fit in anything smaller. Radiator hard to find place to install on most cases. other then that it is a great product, and don't expect them to come out with an adapter for the I7 because won't and don't plan to. Thats why I got the bloodrage instead of the EVGA board that is out right now, it has the mounting holes for socket 757 coolers, and it works great. If you have the money though, go with a better waterblock. I would reccommend the swiftech apogee gtz.

Pros: Supports ESA, doesn't allow My Q9550 @ 3.28 go beyond 40C at full load, Quiet.

Cons: None

Other Thoughts: Take Advantage of the COOLER MASTER COSMOS 1000 RC-1000-KSN1-GP

Pros: It is best to have the Coolmaster Cosmos. works great! Very quiet, and easier then I thought to install. Also can work in series with the Coolmaster video and hard drive blocks.

Cons: I use a gigabyte board and the backplate is more of a heat shield. It states to use the backplate from AM2 boards and I couldn't more because of gigabytes design so I removed the backboard and modified it by using the spring screws design for the Intel chips.
Should come w/ 2 bottles of coolent. Even w/ the mixture of Distilled water it took the entire bottle that came with it.
Installation of the front unit does require a little modification but not much.
MUST use a funnel, there's a space between the tank and the chasis that when water gets between that space it appears to look as if if was leaking.

Other Thoughts: The Cons to me are much more common sense and not as bad as mentioned, but it was the only thing I could come up with. Again the series link between the tubes for other blocks is great!

Pros: With a little tweaking this will fit in a CM 690 case! If you are not afraid to use a drill, screwdriver and pliers you can make it fit this case! Oh, and it also cools great!

Cons: Dosen't fit allot of cases like a glove without doing some body work but it can be done! I just don't know what Cooler Master was thinking when they develped a water cooling system that is so limited in what it can be installed in!

Other Thoughts: Added a Koolance radiator for added heat dissipation because I'm also cooling a GPU and memory with it.

Pros: The UV Glow of the fluid ties in nicely with my case colors. Tube connections are the best around. Hardest part is installing into a case thats not a CoolerMaster comos. I had pre-drilled holes for previous fans which didn't line up with the radiator. It took a bit of thought and luck to get 6/8 screws into place to support it.

Cons: The fans that are included are sharp as razors... Remember how mom tells you to keep fingers out of fans? Remember that lesson well or install fan guards/grills before install.

Doesn't make use of ESA tech as well as it should...

Other Thoughts: Worth every cent! Keeps my CPU at a nice 65-70F. Couldn't of asked for a better cooler.

Pros: It works great had it for a week now cooling my quad core alot better than a heatsink went from 45c to 30c even under full load it does not leave 30c. should be able to use with gpu cooling also haven't bought the water blocks yet.

Cons: takes a couple of hours to install. the tubing is a royal pain likes to kink alot

Other Thoughts: made mostly for the cool master case i have a ultra case but with a little metal working i installed the rad on the back of my case would be nice if cool master would have made a bracket so that it was universal. Still all in all a good buy

Pros: Looks good

Cons: Leaks coolant from the front of the reservoir.

Other Thoughts: This is a new build computer with expensive parts from New Egg. It was a good thing that I didn't slide the reservoir back into the case and power up.

Pros: Easy Install. Room for upgrade. Great Aesthetics. Green theme goes perfectly with NVidia systems. All in all a well designed system.

Cons: Only adequate cooling; would like to see better performance. Replacing the water block with something higher end helps. My Zalman CNPS 9700 cools the same as this.

Intel E8400 3ghz: OC'd to 4.05ghz:
Idle - 45c
Full Load - 55c

Other Thoughts: Looks great, not a bad price, performs decently, and gets your feet wet (pun intended) with water cooling. Great for entry users. If you are looking to water-cool your system cheaply and effectively, this is the way to go.

NOTE: Fluid that comes with system must be diluted with distilled water, but works great when you do.

Using FluidXP non-conductive coolant resulted in very poor flow rate in this water cooling system. Be aware that if you want to go non-conductive you may see a drop in flow speed as a result. Maybe another pump in line would have helped.

Pros: works great...was easily installed in my Armor + case and does its job. and its not too loud either.

Cons: none

Other Thoughts: how bout keepen these reviews actual reviews on the item in question and not about arguing amongst one another.

Pros: See comments below

Cons: See comments below

Other Thoughts: Aquagate does not fit in the Cosmos S case out of the box but Cooler Master will send you the 2 rails need to mount the radiator in the Cosmos S case FREE of charge, just email there customer support and they will ask you to fill out a request form for the rails and there you go.

Pros: See other thoughts.

Cons: See other thoughts.

Other Thoughts: @ Elementaldragon. I own both the Cosmos S case and the Aquagate max. on the box for the Cosmos S it clearly states the Aquagate Max as a recommended product. It also shows a picture of the Aqugate Max inside of the Cosmos S. Please do not come here and do a review accusing someone of writing a bad review. You really need to look at what is being said. It clearly states and shows the Aquagate Max in the Cosmos S on the box for the case. It also does not state that it only works with an ESA chassis. It states that it will work with an ESA compliant motherboard which is something i also have. You really need to do research and not accuse before you make yourself look really dumb. If you would like proof that the box for the case has this on it i will show you a pic of you like. See me at EVGA forums under same name and i will prove to you that it is showed in there. Dont dig yourself a deeper hole.

Pros: see other thoughts

Cons: see other thoughts

Other Thoughts: Actually.... i have done my research. I've seen pictures of the Cosmos S case, and i have never seen a glimpse of this cooler in the Cosmos S... not even a suggestion of it being used in the case. It's not even shown in the case on Cooler Master's website. All it says is that a single, dual, or triple 120mm radiator can be mounted in the top. And do you want even MORE proof that this specific radiator isn't recommended by Cooler Master to be used in specifically the Cosmos S? How about you take a look at the Support tab for this particular cooler on the Cooler Master website before you call me a fanboy for providing accurate information. There's a SINGLE QUESTION, asking if the Cooler Master Aquagate Max will work in the 690 chassis. Their response?

"No, it only support ESA chassis."

The Cosmos S is not an ESA chassis. Neither is the Cosmos 1000, but it has the same design as the Cosmos 1010, which is ESA certified. If you're still not convinced, i'm in EggXpert same nick

Pros: Skip to other thoughts

Cons: Skip to other thoughts

Other Thoughts: ElementalDragon: You should look for more info before criticizing someone else's reviews. When you buy the Cosmos S and you look at the box,there's a picture of this water cooler kit mounted in the cosmos s,even cooler master recommend this kit for the cosmos s outside in the box , so please stop being a fanboy and let the owners do their job.

Pros: *see other thoughts*

Cons: *see other thoughts*

Other Thoughts: Hate doing this to reply to someone's review (Newegg staff: really think Customer Reviews should have a reply function so that someone can point out stuff like this without affecting the overall rating).

Mine>Yours: I don't think you looked at it closely enough. They never show this kit being installed in the Cosmos S 1100. The kit was basically designed for the original Cosmos 1000.... the one that focused on silence. the top panel supports either two 120mm fans, or two 140mm fans, which then needed the holes for 120mm fans to be separated further than normal. This made it rather difficult to mount any kind of radiator in the top of the case other than a 120x120mm radiator. Coolermaster seems to have released this kit almost specifically for this reason... as a good, quick, and easy water cooling kit for the original Cosmos. You could have just as easily picked up a different dual-120mm or triple-120mm radiator for the top of the Cosmos S 1100 and it would have worked fine.

Pros: This kit looks amazing and cools very well. Everything came packaged very well and fit together nicely. Looks nice in a Cosmos S 1100 once you get it in there. Dropped my idle temps on a Q6600 @ 3.6 from 28-29 with a Zalman 9700 to 25-26 Celsius. The load temps dropped from 60-64 with the Zalman to 54-50 with this kit. I would say it works very well. Very well thought out kit and very well made. No leaks and everything fits nice and tight. It works great with a ESA board as you can see the loop temps with the sensors on the desktop. You can also adjust the fans for the rad from the Nvidia Control Panel.

Cons: Well where to start. the radiator did not fit in the Cosmos S without a little bit of thinking. I had to loosen two screws that held the top side covers on just in order to fit the radiator in there. The predrilled holes on the radiator did not line up very well with the holes on the case which didnt matter cause the screws that come packaged with the kit are not even long enough to screw into the rad from the top of the case. I had to find and use some other scerws that were long enough. I had to cut 4 slot locks on the top slide cover off in order to get the top back on without it hitting the side of the radiator. I could only put the radiator in one way to make sure the hoses would not interfere with anything on my motherboard. Cannot get the air bubble out of the res to make the wheel spin. I tried everything. Tipping it on its side like they suggest but still in there.

Other Thoughts: Its a very nice well put together and thought out system. I just think they overlooked some things that their customers might have to work around or may cause them problems. If they post pictures of it in a Cosmos please make sure it fits before releasing it. It took me about 4 hours just to get the CPU loop in. Like i said earlier it cools very well. It dropped my load temps by about 10 degrees. Would like to get my hands on more of the fans that come on the radiator but cannot seem to find them anywhere.

Pros: Looks good; nicely integrates components; expandibility

Cons: Haven't seen a review from a trusted site yet, so can't say how good it really is.

Other Thoughts: I've read in a couple of reviews online where this won't fit in the Cosmos 1100 S case, and one said that an adapter plate was needed. If true, talk about an oversight from CM as their own website shows this installed in the case.
