CPU liquid cooler

Robert W. Gamble "bobby", Amazon
3 weeks ago
  • Summary: It is pretty quiet if connected properly but my first connect was wrong and it made this liquid CPU cooler very noisy. Once I got it connected properly it runs reasonably quiet and it lowered the CPU temp by about 25 degrees. I cannot speak about its reliability yet since I have only had it a couple of days but it appears to be a quality CPU cooler.

this unit does no better than my coolermaster EVO 212 (

Chris Lagemann, Amazon

  • Summary: I'm not that impressed. Unless I'm doing something wrong, this unit does no better than my coolermaster EVO 212 (?) air cooling unit. As a matter of fact, I think it's about 5-9 degrees (f) hotter than with the other cooler. I have the fan blowing inward to blow cooler air trhough the box and even added another side fan. No difference. I'm running it on an fx8350 black edition 8 core processor.

Stopped the clicking sounds coming from the pump

Min, Amazon
16 November 2014
  • Summary: If you hear some clicking sounds from the pump, here's a couple things to check: * you may have the pump connected to the cpu fan header. Try putting it into a sys fan header instead * and tell your motherboard to 'spin' that fan at around 60% I was hearing the clicking when the pump was 'spinning' too slow or too fast (50% and 100%), somewhere in the middle seems to make it happy.

Good but I think the V version is better.

Michael Garcia, Amazon
12 November 2014
  • Summary: After installing a number of AIO cooling systems for my PCs I found this one to be right in the middle. It installs easily. The tubes are stiff but you can manage the angle to make for nice clean airflow to the radiator. The back plate was a little tougher than others to manage since it was secured buy the heat sync and not with screws first then the heat sync like others of the genre.

I can't believe how much I paid for a piece of ....

JS, Amazon
7 November 2014
  • Summary: GARBAGE. Just took this thing out of the box. The pictures don't match the parts list and the instructions are next to nothing. There is a part in a picture for AM3+ that doesn't even exist in the parts nor did it come with my new motherboard. Additionally, the description states "Pre-applied thermal compound is also included."... WRONG!!! There is thermal compound, but nothing applied.

The performance of this cooler depends on you BIOS.

Ronald Buckingham, Amazon
21 October 2014
  • Summary: Thankfully, my Asus Z971-Plus automatically utilized this cooler to keep my CPU at a temperature under 40 Celsius (I'm Canadian). This is the first water based cooler I ever used, and I am impressed and considering getting a water block for my GPU. These devices are great at cooling!! Just make sure your BIOS is configured properly, that you assembled the fan rig correctly, and applied thermal paste in "proper" amounts.

Great cooler, could be just a little better

Glen Martin "the rev", Amazon
19 October 2014
  • Summary: Great performance ... running memtest86 5.0.1 with a 4690K, my reported cpu temp dropped from avg 51C using the stock cooler, to avg 39C with this one. The heatsink just barely fit interior to the back of my case, a cross strut is right up against it. In a pinch I could have filed a bit off the strut, but happily I didn't have to. Otherwise it was dead easy to install and the kit came with everything I needed.

All good save for the box fan

R. Helms "Casual gamer", Amazon
9 October 2014
  • Summary: After a year or so, the fan in mine developed an annoying rattle. Apparently, the bearings in it are cheap. Aside from that, the instructions are moderately easy-to-follow, and it fits quite well on an Intel or AMD series CPU. The hoses are quite stiff, making placing the fan inside the cabinet difficult at times. It is a sealed system, so the fluid part and circulatory system should not give you maintenance headaches.

Not cooling that great :p

DeuceX,, TigerDirect.com
26 September 2014
  • Summary: I really expected water cooling to keep my CPU under 60 deg C but When playing high graphic games it can get up to 67 deg C. AMD chips run pretty hot compared to Intel but still. It was really important to install another intake fan to suck air into the case which significantly improved the cooling. When it's running on high fan, it's loud!
