Summary: I'm using this on an Intel Core i7-4790K and it keeps the temperature around 70C while running Prime95 (Version 26.6) small FFT's with the fan at 100%. The latest version of Prime95, which really shouldn't be used for this CPU I've read, will push the temperatures well above 100C with the stock...
Pros: Easy installation. The thermal paste seems good enough and the fan provides adequate airflow.
Summary: My processor works 100% all the time. Doing a lot of Seti at home processing. With stock cooler the temps were hovering around 85C on all 4 cores. With the new Enermax cooler and 100% load on all 4 cores temps went down to about 50C.
Pros: Silent compared with stock cooler. Works great.
Summary: I didn't trust the fan due to my perception that it is not very high quality. I changed it out right off the bat and installed another well proven manufacturer. I am not deducting eggs for this because there was no actual failure.
Pros: Great for 5820K. Fairly easy installation procedure. Works very well. Well constructed heat sink. This thing is very large, so don't expect it to fit in a small case.
Cons: No real cons. Although see below related to the fan.
Summary: This fan is excellent. We all know that AMD CPUs run hotter than NVIDIA ones, but this aftermarket cooler is a lot better than the stock one and is top notch for the price. The only drawback so far is if you run 4 sticks of ram, this fan will cover your 4th slot so be warned.
Pros: - Really quiet running games on Ultra settings - CPU stays cool doing high demand gaming
Summary: Very easy to install. You have to have patience! This thing is heavy! It's made of solid metal! It is going to be a bit of a pain if you mount it to the motherboard yourself! Better to ask for help/extra hands!
Pros: Currently running Intel i5 4650k Devil's Canyon at 4.4ghz flat! Running 4x4gb memory OC to 2133mhz. CPU runs perfect and stable with this heat sink! It is massive! That is for sure! Barely fits in the "Rosewill BlackHawk" Mid ATX case! I had to remove the side panel fan so that the cover could cl...
Cons: Very large but, what else you expect?! It's not water-cooling! Make sure you do measurements! I didn't but, I already knew the case was wide. Overall, nothing to complain about!
