5 out of 5 eggsBIGWATER 745

Pros: does the job, great cooling, fan can handle 20V that's what i ran it at for a couple of months and then it burned out, no biggie fans are cheap. free pump replacements up to 3years from Thermaltake!!! i'm on my 3rd one now.

Cons: if you run this without water it will destroy the pump in seconds, DON'T RUN FOR A SECOND WITHOUT WATER.
i'm on my 3rd pump in 2 years, but its my fault for not maintaining the water

Other Thoughts: you don't have to use any special fluid, just go to a auto store and get regular coolant. way cheaper.
get another pump, so when you send this for warranty it will take a couple of days maybe weeks.

5 out of 5 eggsBest Liquid System Ever

Pros: I've had this system for about 4 years. You can add almost anything to this huge system. Currently have 2 VGA waterblocks, 2 koolance RAM waterblocks, HD waterblock, and awaterblock for my NB in addition to the system and the pump handles fine. My pump seems bullitt-proof. after the first year it started acting funny and i thought it was going out. But when I cleaned it out I found some particals that might have been from one of my waterblocks. I cleaned it ou and havent herd so much as a hiccup form it since. OC CPU 32C at idel and 47 at full load.

Cons: If you're lazy like me dont use the coolant suplide. Just like on a car you have to change out the coolant at about 3 to 5 month. Ate up my aluminum RAM cooling block. I just used distilled water now and change it out every 12 to 18 months.

Other Thoughts: Before you put everthing together, put teflon tape on all fitting. Great precautionary measure.

2 out of 5 eggs2nd Thoughts

Pros: Cheap

Cons: Unreliable. My first pump went out in 1 1/2 months of use. Wasn't even left on 24/7. My second pump went out in 6 hours. Thanks to the quality of referb parts you get from Thermaltake. The turn around to get a replacement took almost 4 weeks. I'm still waiting for my 3rd pump.

Other Thoughts: I think you would be better off with the money spent here for researching and building your own from quality parts. I promise you it's easy to do.

4 out of 5 eggsService two thumbs down.

Pros: Awesome system goes in quick hassle free. Great price for what you get, and of course it looks great.

Cons: The only con I have is I bought this 3 months ago and the pump has already gone out. They don't provide enough fluid to fill the system. Even though they said my thermaltake case would hold it I still had to mod the case to hold the system.

Other Thoughts: After having my pump go out in this system I have been convinced I will never buy another Thermaltake product again. If you look at their site there is no way to contact them besides an e-mail form that doesn't work. Nor does their online chat. I've bought several products from Thermaltake, but never again.

4 out of 5 eggsBefore Buying

Pros: Great radiator column for cooling.
Very secure tubing connectors.
Easy to install CPU block for 775s.

Cons: Bulky, I almost didn't fit it all inside my Thermaltake Mozart, so if you have a normal sized case most of it will have to go outside.

CPU Block: be careful here, the I bracket that hold down the Water block almost didn't fit on my Striker Extreme, so make sure there nothing odd on your motherboard that could get in the way.

Other Thoughts: Before you buy consider the amount of tubing you might use. After installing into my Mozart case Theraltake had not provided enough coolant to fill the system properly, so you might require more.

3 out of 5 eggs

Pros: Great temps on my OC. 805D at 3.8ghz 24/7 rock stable. Instructions worked great and were easy to follow. Quality hardware.

Cons: My heat sink leaked out the side after 6 months of use. Tubing kind of cheap, it kinks super easy.

I had zero problems with the rest of the hardware.

Other Thoughts: I have stopped liquid cooling for now until finances are a little more flexable to replace parts in case of water damage.

Will do a custom set up for the next one probably using some of my hardware from this build.

5 out of 5 eggsGreat cooler, but on the noisy side

Pros: Moves a ton of liquid. If you only cool the CPU, it only needs one of the radiators. With only the small radiator, it keeps my 3.01GHz E6600 at a constant 45C under full load.

Cons: Pump is loud. No louder than my previous Air-only system, but still loud.

4 out of 5 eggsnot bad for starters

Pros: cools my 3800x2 at 2600 39 load and 32 idle. i cut the top off of antec nine hundred and put the external 240 on top. the fans on the 240 are pretty quite.
its not a bad starters kit. to peice a good kit together you will spend almost twice has much.

Cons: the 120 for the back can be loud but it does come with a fan controler. the pump is louder then 16 they claim, more like 26. you do have to be carefull putting the hose on because the solder joints are not soldered very good and will spin when you tighen the fittings.

Other Thoughts: i got rid of the green hose and put clear hose and put blue fluid xp in it. so far it has been running for two weeks.

5 out of 5 eggsGreat Cooling System

Pros: Kit has everything you need to get started on a complete liquid cooling setup. My temps went down roughly 10-12*C -- My current setup= (2) Opteron 2220, 8800 Ultra (liquid cooler block - BFG) 8Gig RAM, 800W PS (thermaltake), (3) WD Raptor 1500D in RAID0 array... all housed in a Thermaltake Armor case (black).

Cons: As with most Thermaltake equipment, you really need one of their full tower cases to use this to it's full advantage -- also with no modifications. Also did not have enough coolant included -- needed an additional 250cc.

Other Thoughts: My water flow = Pump->CPU#1->CPU#2->single 120 Radiator->8800 Ultra->dual 120 Radiator->Res->Pump. This setup was very easy on my Armor case and works rather well. Be sure to by extra coolant as I had to use a total of 750cc (only 500cc included). Had more than enough tubing and other goodies. Highly recommend this to anyone that owns a Thermaltake Case!
