Summary: Used in a HTPC build with Gigabyte Micro board. It has been in use for 2 weeks and CPU temps are 24C at idle. Full loads at 48C. With board control I don't think the fan is noisy at all. Unless your going to put right next to your ear. Inside my Silverstone case you can't even hear it.
Summary: Had this for 3 days now and its doin a great job, cpu heat went down from 59 C to 37 C. Just be carefull on install, you have to find right direction before you lock it down. My games and overall pc is doin alot better.
Summary: Works fine with my Intel LGA1156 cpu. Had an assembly problem when the single clamping screw thread stripped while tightening. Had to re-tap the thread for a larger screw. Not the best design for holding the cooler against the cpu.
Summary: My home server kept overheating and shutting down when encoding HD video using handbrake. (4TB Raid 5, Athlon II x4 640 quad core 3.0 ghz). That is until I got my new vortex plus CPU cooler. No more over heating, cpu runs 15 degrees (Celsius) cooler , and the fan is extremely quiet. HIGHLY recommend!
