4 out of 5 eggsImpressive

Pros: Simple all in one kit.
Basic Setup.
Fair price.
Powerful enough for upgrading.
Included 1366 socket adapter.

Cons: Aluminum Radiator.
Noisy stock fan.

Other Thoughts: I bought this cooler for my CPU which I primarily use for h.264 encoding. (i7 920 @ 3.8Ghz) With a little tweaking this is really and impressive little kit.

I did away with the black tubing (1/4" ID) and quick disconnects and used the 3/8" ID tubing throughout.

I added a second radiator. a swiftech 120mmx2
Then a third with hopes of expanding this loop to my crossfirex 5870 2GB VGA cards.

The pump is silent and appears to be working very well.
My cpu idles at 4 degrees above ambient and sits at 30 degrees higher under load. I believe the limitation is the CPU water block.

This was my first watercooling attempt and this kit made it extremely easy. 3 months strong and no leaks!

Buy with confidence.

5 out of 5 eggs

Pros: +It's quiet
+Keeps my CPU temps low (36C) Stock [Core i5-760] / OC to 3.3Ghz (41C)
+Not hard to install as long as you read the instructions carefully. Great for those who have never done water-cooling but want to watercool their CPUs (like myself)

Cons: -Takes two drive slots. (Not really a con but its big, would recommend a Full-Tower case)
-No way of knowing if its flowing or not. (Flow meter would have been nice)

Other Thoughts: This is my first time delving into liquid cooling but overall the enjoyment of building this kit together was great. I decided to go with watercooling because I wanted to OC my new Core i5-760 as far as i could.

So far I haven't noticed any leaks at all. The quick connectors are great although it leaks a bit of liquid when disconnecting it but its not much. (Not sure if that is normal or not but do be aware to have a towel ready just in case).

Also I just wanted to leave a note here, that this kit IS compatible with LGA 1156/1366 even though it's not stated under the Details.

3 out of 5 eggsGreat at first

Pros: Keeps your system cool, easy to install, easy to refill (if you have a Thermaltake Armor+). Fits in 2 of my drive bays.

Cons: After a while, it started to leak on me, out of the top, no matter how low the coolant was. The pump is not as strong as i thought it would be; it can't move a flow meter.

Other Thoughts: I've had this system for at least 3 years, and i really wish i could say it was awesome, i love Thermaltake. They do great in every other department but i can't say i'm buying any more liquid cooling systems from them again. I love how it fits in the front of my case perfectly (I bought a Thermaltake Armor+). But after a while, it was the first thing to start causing problems. It seems like it started leaking fluid right out the top of the reservoir until the pump started capsizing. I have to put paper towels down on top of my blu-ray drive to soak up the coolant that drips off... ghetto.

5 out of 5 eggsStill Going Strong

Pros: I still have this running in my system for well over a year now and it keeps my AMD Phenom II 955 (overclocked to 3.6 Ghz) nice and cool. It wasn't a huge difference in temps going from an Arctic Freezer 64 (air) to this but the temps have been more stable. It does not heat up as much while gaming. I really like the quick connects for ease of disconnecting if you need to change something but I feel they may also restrict water flow. My girlfriend has my old Arctic Freezer 64 and has to clean the heatsink like every month, I clean my radiator once every 4 months or so and didn't do it for like 8 months until I noticed temps were getting high. It looks way cooler in my opinion and opens up the airflow in your case because you don't have the huge heatsink and fan in the way. One thing to keep in mind; when these units fist came out they were completely different than the ones sold today. Watch some videos on youtube and you will see the original, which gets bad reviews.

Cons: Only thing that has happened to this unit was the cooling fan on the radiator died on me, I bought a more powerful Cooler Master Fan and installed it... it works better than the one that came with it. The quick connects, although nice, also reduce the tube size at that point. I am not sure if they designed the connects somehow to compensate for this but it may reduce the effectiveness of the cooling. The barbs on the pump are smaller than the 3/8" that the tubing is, this may also be a problem with water flow.

Other Thoughts: I have no complaints about this system at all, it was my first water cooling system ever and it's been a learning experience. I would recommend this type of setup for someone who doesn't want to spend $300 and wants to 'get their feet wet' so to speak. I found that there are two things in my system that greatly affected the performance of this unit...

1. Don't put too much thermal paste on, a very thin coat should be sufficient. I put too much on and my temps were very high... idle in the 46 to 48 C range. I removed the water block and reapplied the paste very thin and the temps went down into the 36 C range at idle.

2.The other thing I noticed was how hard to put the water block down... I used a lot of force once and it did the same overheating affect, loosened it a bit and it was great. You want it snug but should never torque it down, you could possibly damage your CPU and motherboard by putting too much pressure!

You may want to lap the water block too.

5 out of 5 eggsan all in one i trust

Pros: an all in one that keeps me from parting a kit together. Works well. keeps my CPU @ 42C 2 1.51 volts. also cools my N. bridge and South bridge very well. pretty quiet.

Cons: had to bend the case on the back corner to get it to clear my mobo and some ram.
fan speed control is not on the faceplate.

Other Thoughts: I added another radiator just to be safe and i really did not need it. keeps everything very cool and is MUCH better than a lot of fans.

4 out of 5 eggsGreat product

Pros: Easy install, plenty of hose to work with, adjustable fan for quiet operation, no leaks,

Cons: A little too large for a mid tower case but it did fit.. I got lucky it fit. I have a (4) 5.25" bays and it would only go in the middle two. The top bay was too small with my power supply right behind it. the bottom bay was too tight because it bumped into my mother board and would not slide all the way in.

Other Thoughts: This is a good item for someone just getting into liquid cooling and doesn't feel confident in buying everything separately.

4 out of 5 eggsGood for overclocking easy to install

Pros: Keeps processor about 5 - 10 degrees cooler compared to my rockfish aftermarket heatsink/fan combo. Not to hard to install. No leaks. Instructions are small but clear. Gave it 4 out of 5 stars, see comment below.

Cons: It was not designed for a mid tower. I am using a thermaltake armor Jr. and the bay unit is big. Depending on your motherboard it will not slide all the way in without jerry rigging. I am currently using an Asus P5N32-E 680i. Like others have said it hits the motherboard. I had to use a hammer to slighly bend the sideplating so it could clear the mother board and slide over the floppy drive connector. (plan on not using a floppy drive with this.) in slots 2 & 3 it clears the floppy drive connector but hits a transister. Therefore, I had to put it into slots 1 & 2 where again it clears the floppy drive connector but this time goes into the 4th ram slot. So your options are either use 3 ram sticks or use 4 and have the unit stick out an inch.

Other Thoughts: This unit is great for overclocking. At normal speeds I see little difference between my aftermarket rockfish heat sink and fan combo. However, it really shines when I overclock my system from 2.4g - 3.6g. I notice about a 10 degree C cooling difference. People who don't notice a difference are either using expensive aftermarket fans, didn't apply thermal grease correctly, or didn't install according to instructions. I am happy with my purchase but not sure if its woth $150 because a fan/heatsink does the same thing if you don't plan on overclocking.
