Pros: SUPER cool CPU
Easy setup
Affordable

Cons: Appeared to be missing a small washer
Louder than Corsair H series (although personally not a con for me)

Other Thoughts: Bought this for my 5820k recently to replace the Corsair H50i that crapped out on me after a year and started sending my temps around 80c idle, was not happy.

I may be slightly biased on the setup due to the fact that I was able to use the same backplate from the Corsair and did not have to remove the motherboard, but the setup was very easy, exactly the same as the Corsair. Case is full size HAF-X, so space was not an issue.

Temps now around 22 - 27c idle, just over 30c for mild activity, have not yet stress tested. Fans are louder but certainly not too loud, I think a big performance PC should have a little grunt to it personally. If I cared about noise, I'd drive a Prius and own a Mac.

Pros: Extremleycool temps. AMD FX 8300 idle temp is 6c. Temps rarley go over 35C
So far so good!

Cons: This product has some of the poorest documentation I have ever seen! If installed on an AMD machine it is even more difficult. The instructions are extremley unhelpful and so is the Thermaltake website. This is my forst forray into water cooling. Even though it works well right now I don't think I would purchase another Thermaltake cooler again. Complete lack of support. I am unable to control the fans as the the thermaltake software still does not recofnize the cooler. I have seen this issue over and over again on the forum threads and the company does not seem interested in anyway about addressing this. The mounting brackets for the intel install are much more robust than the AMD. It took longer to mount because of the poor instructions than it took to build the entire PC from scratch!

Other Thoughts: If poor customer service doesn't bother you then this is for You!!!!!!!

Manufacturer Response:

Dear Customer,
We at Thermaltake apologize for any inconvenience this has caused.
The unit you have is the Water 3.0 Extreme S (CLW0224-B). That version does not come with software like the original 3.0 Extreme (CLW0224), as there is no USB connector. For your version, the fans will be connected to your CPU fan header and throttled by your motherboard.
If you have any further questions or concerns, do not hesitate to contact customer support.

Pros: Setup was straight forward, Fits in my CFI case just fine. The cooling is much better and the fan setup gives me more overall cooling ability and control. Instead of the cpu heat blowing around in the case it is directly blown out the top of the case.

Cons: None

Pros: Water cooling. This will help keep a CPU cooler at higher loads than a fan.

Easy to install. It was a snap to install.

Quiet

Cons: None

Other Thoughts: I recommend this product, especially if you have a Thermaltake full tower case like the Chaser A71 or one like it. I love the design and the concept of water cooling systems. I just think their cool. I recommend any Thermaltake product.

Pros: It works even at 100% load stress test, cpu (i7 4790k) stays in the 55-60 degree area, normal/ low use stays around 30-34 degrees. And quiet.

Cons: Installation instructions have no words just vague pictures for similar looking parts, boy some words would have been nice.

Doesn't 100% easily fit in Thermaltake's A31 Chaser chassis, it took some fandangling and ugly cable management to make it fit, as the the power pin to the motherboard / some other parts of the motherboard are kinda really close. This tight fit could be alleviated if you wanted to personally drill some holes and mount the fans on the top of the case vs the inside like the instructions show.

Another Con was the "backplate" kinda cheap plastic would have preferred something more solid, and the front mount is really difficult to actually screw down, and I really feel could be improved on. So I have to knock a mark off for it.

Other Thoughts: Aside from the installation which is still worlds less work then a custom water cooling solution, really could have a bit of improvement, I can't really find anything else to complain about.

Pros: work very good I'm very happy with it & it fits my Thermaltake chaser A31 just fine

Cons: none at this time

Pros: work very good I'm very happy with it & it fits my Thermaltake chaser A31 just fine.

Cons: none

Pros: Works real good.

Cons: This Thermaltake water cooler would not fit the universal screw hole pattern on my Thermaltake case, they made a cooler that wont fit their towers.

Pros: keeps my amd. 9550 cup cool as can be

Cons: none as of yet

Pros: Very easy to install. Does require motherboard removal for back plate. Maintenance free system. Comes pre assembled and filled with cooling fluid, just install, and go. Worth. Every. Cent.

Before, my 4790k in my micro atx case would ping 100c and throttle down during a prime 95 torture test with in 30seconds to a minute. This had less to do with an issue with the processor and more to do with the lack of flow in my small case

I got a ~9700 with my current setup (on the stock cooler) on 3d mark

After installing this unit, the prime 95 torture test held at 66c. Remarkable.

added 300pts to my 3d mark score to 10,000

Additionally, it should be noted that the stock cooler that comes with the 4790k is quite noisy. Once I installed this unit, its silent. I havent event started playing with over clocking yet. Lots of flexibility given the two 120mm fans are running at about 600-800rpm with turbo running 4.4ghz

Cant say enough good things about this unit. Highly recommended

Cons: None as of yet.

Other Thoughts: Required some modification to my small box to accommodate the large unit, but it was more than worth the time spent to get it to fit.
