Irony at its finest: I had taken the dust filters off my rad fans to see if I got better temps, and I did. So I planned on just putting the metal grilles back on the fans to protect the blades. I went to shut down the computer to remount the fans with the grilles on, and when I reached around the back of the rad, I put my finger in one of the fans and broke a blade off
The only other 120mm fan I have laying around is an 800rpm fan, so I have that installed along side the surviving stock fan. I have taken my overclock off and enabled cool n quiet just in case. Temps are fine under Prime95 though. Looks like I'll be getting new fans sooner than I thought. Are Yate Loon High Speeds comparable to AP-15s in static pressure? I'm not concerned with noise at this time.
