Impressive cooling, fan required
11 November 2013
Summary: The description on Amazon led me to believe that this is a fanless cooler, thus not requiring a fan. Wrong. The unit DOES require a fan, but does not come with one. I was looking for something silent. If I had known a fan was required I would not have purchased it. A side note about the effectiveness of the unit: My girlfriend bought one of these at the same time I did. Her idle CPU temp went from 33 degrees Celcius down to 21 degrees. Impressive indeed.
Summary: I've been building my own custom computers for over 15 yrs. I've always used a 100% air cooled system up until now. With recent high end cpu clock speeds in the 4ghz range air coolers have gotten ridiculously large and hard to work around. I really didn't want go 100% liquid cooling because of the expense and trouble so for my recent build I decided to go liquid on the cpu only.
Summary: Took me a bit to figure out how to mount it... But when i did, it fit firmly and obviously seated against the processor. My cpu temps are constant. Hoses barely reach to my box's exhaust port.
Summary: Ok, I'll admit I made a mistake! I bought this without any fans and ended up using my case fans to push air through it. Surprisingly, the temp of my cpu drop 50 degrees. It rarely goes about 119. Mother board is now staying around 109. Later I purchased a couple of Corsaid fans to use with it, and it still runs great, and a lot quieter than I expected. If you've never replaced a cpu fan of the newer types, make sure you READ all the instructions.
Summary: The mounting instructions are somewhat lacking. Even after watching youtube it was difficult. They aren't clear on how the back plate mounts. On my sabertooth z77 I had to twist the plate to line up with the mounting holes.
Summary: I bought the H70 (with no fans, I used my own) off of Newegg with a $20 rebate, and it was a very good purchase in my opinion, although I didn't really see a good improvement until After I added a second fan. My case is very small for a gaming case, and I can only fit one fan on the cooler before it gets in the way of my RAM.
Summary: Grabbed this in addition to a bracket from triptcc's website and was able to mod my GTX 580 in one afternoon. My temps were previously hitting 99+ degrees C under 100% load and this dropped the temps down to 60C max, with idles in the 30s. Much much improved. Beware the tubes coming from the radiator aren't as long as they seem. I was only able to mount this+fan to the back of one of the hard drive bays in my 650D case.
Summary: This was my first Corsair water cooler. Also my first 'all in one' water cooler, my previous builds all have 'built' kits which involved pumps, reservoirs and tubes, etc. Effective though. This unit is also pretty effective although I will admit I don't stress it very hard. However... The unit did fail (pump) after about 13 or 14 months (the machine is on 24/7). Contacted Corsair who shipped out a H80 as a replacement right away.
