4 out of 5 eggsGreat results w/ R9 290x + NZXT g10 + new fans

Pros: Fairly quiet from low to 1500 rpm
Cheapest asetek based cooler after rebate.
Radiator is shallow and easy to mount in midtowers
PWM fan included
On start up pump is audible and indicates it is working.

Cons: No Specifications on fan
comes with only 1 fan without a zalman option to get another.
Prepasted (decent paste though)
Min fan speed is not practical b/c radiator near scalding hot.
No indicator for pump function on this model.

Other Thoughts: Using this cooler with a NZXT g10 bracket attached to an R9 290x reference card. results as follows
Before upgrade
Generic cramped mid tower case: r9 290x reference cooler uber profile 92*C gpu stock of 1000mhz throttled to 940-970mhz

AIO cooling added:
Generic mid tower case, original zalman fan, r9 290x ran 78*C with fan at 100% during torture bench. 1100,hz OC

Final upgrade:
corsair 540 case, push pull sp120 high pro pwm 2x fans at 70-85% using gpu fan profile. GPU 60*C stress test @ 1110mhz core.

ambient temp 26-27*C (80s)

Cons: I mentioned the install was easy but i did have to fidget with it for awhile and make my own modifications to fit on my motherboard

Other Thoughts: One egg for the install issues i had

5 out of 5 eggs30 degree temp decline

Pros: 30 degree temp. decline over OEM AMD 8350 fan says it all. I added a second fan to the setup which was easy as the cooler is designed to take two.

Cons: Instructions.

Other Thoughts: Installed on a 1 year old build so I had to take everything apart in order to fit the back plate to the bottom of the MB. Instructions somewhat sketchy but, in the end, I was able to get it installed in about an hour.

5 out of 5 eggsPain to install

Pros: It keeps my CPU really cool compared to air cooling. between 30c - 50ish depending on what I am doing.

Cons: This can be a pain to install. Instructions aren't exactly clear so if you have never installed something like this before, then do some research on how to do it. Instructions are Bias against AMD CPU's and lean towards Intel oriented instructions. Takes up a lot of room with two fans installed, but does a better job than air cooled.

Other Thoughts: Its not extremely bad to install, but could be easier if the instructions are clearer. I am sure the foreign language instructions are clearer, but I cannot read them so it wasn't much help. I have my radiator set up with the hoses on the bottom and the block with the hoses on the top and I am getting good temps without any gargling sounds from air being trapped in the system.

5 out of 5 eggszalman lq-310

Pros: keeps everything cool. i've had this unit installed on 2 different cpus now (phenom2 965be & fx-8320) & keeps temp around 34C.
is very quite, no noise whatsoever

Cons: wish the hoses where a bit longer so i cound have mounted on the bottom of my case beside of the psu and used the back fan to cool the vrm's

Other Thoughts: i installed a second fan in push/pull before i mounted it inside the case.
radiator is a dust catcher and i take the air compressor to it out once a month. but this is not the makers fault

5 out of 5 eggsOh Yeah!

Pros: Cool, quiet, and trouble-free. This cooler has been keeping my i7-2600K cool for bout 2 years now. Performs flawlessly regardless to how much I overclock. Actually I only tested the overclocking ability in the beginning and now I run the chip on a normal setting. It's good to know though that no matter what I want to do (overclocking), this cooler Is ready for it.

Cons: None.

Other Thoughts: This cooler is absolutely silent. I'm not sure if the silence is because I have the NZXT H2 (quiet case) but I can't hear a thing. Keeps my CPU cooler than that bear in the Coke commercials.

2 out of 5 eggsDecent at cooling but not much else

Pros: It keeps my unoverclocked i7-920 15 degrees cooler than the stock heatsink/fan but then again so did my Corsair A50 and I would expect a liquid cooler to do better than a aircooled solution.

Cons: -Fan and waterblock take up a lot of space so make sure it will fit in your case before purchasing.
-The fan is not silent but at this price point you can't really expect an inlucded high-end fan
-The pump is very noisy for a closed loop watercooling system. Even louder than the fan.
-The heatsink that sits atop the cpu feels like cheap plastic and is prone to rattling.
-There are better products to be hat at the full retail price, only purchase when on sale

Other Thoughts: Not worth the price unless deeply discounted.
