Summary: I'm running an AMD 8370 CPU and this thing keeps it cool as can. I was playing GTA V for a few hours and my CPU never got over 30 degrees Celsius. I'm glad I didn't mess with liquid cooling. Between my full tower and this cooler I have no problems at all.
Pros: Price, performance, and quiet as can be. Cools great
Summary: Size isn't too much of an issue and over clocking is perfect (for me), for the Intel i5 4690k Devil's Canyon processor. Had been running this thing hard for a few months and no problems at all!!!
Pros: Excellent cooling capabilities! Have this thing cooling my OC'd i5 4690k to 4400Mhz without breaking sweat! Mounted to an AsRock Fatal1ty Z97 MOBO inside a Rosewill Blackhawk ATX case. Quiet but can get loud at times.
Cons: Blocks RAM slot 1 but easily resolved by moving fan up a bit. Super big and very heavy can be a problem for cheap mobo's. Had to remove side fan from computer case to make clearance for closing case panel.
Summary: I installed this on a fresh board. Installation is not as daunting as some of these reviews make it sound; more than likely, they left their boards in their cases. Use the guide to make sure the fan is mounted on the proper side of the heatsink, and don't force the fan clips; just give them a little...
Pros: Solid construction, dropped my FX-8350 OC temps by ~25C
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.
