My desktop is as follows: i7-920 (stock: 2.66ghz, currently: 3.0ghz) Thermalright Venomous-X cooler w/ 1 fan 24gb 1600mhz ddr3 (G.Skill) Nvidia GTX 660 (bought it because it was hackintosh friendly) Tons of harddrives Gigabyte X58-UD3R motherboard (v1.0) Dualboots Ubuntu 17.04 and macOS Sierra (hackintosh) I'm hoping to push it to 3.4-3.8ghz on air. To do that I'll need a second cpu fan (really, I'll just get 2 new fans) and a good cleaning of my case (its been awhile, its super dusty). Any recommendations for 2x 120mm cpu cooling fans? I'm not worried about noise, my computer is in my home office and won't disturb sleep. It does run 24/7 though. I'll post some pics of the case cleanup and the new fans once I get them.
