Summary: My i5 has barely been tested, but I worry that it won't survive a simple overlock with this cooler. Motherboard reports CPU temperature an average of 87 degrees. The fan is relatively quiet, but does not produce much suction/blow. About as effective as a 120mm case fan. It's so big, it nearly didn't fit. In fact, part of it is resting on top of one of my RAM cards.
Summary: Probably okay for a light computer user, and some video gaming, but not at all for creating digital media (Adobe Illustrator, Premiere, After Effects, etc). -A little too big. The edge of it is actually resting on the heat-spreader of one of the RAM cards. -Average temperature is about 35C during cool days and 45C during hot days. However, you can't overclock at all with this cooler, as it springs to 85C+ during any rendering or media conversion.
