So i received the cooler, and installed it, idle temps are like 30ish, but as soon as I run Prime95, i get a BSOD?
Games and stuff are okay
Add more voltage if you can and assuming your temperatures allow it. What voltage are you at now? Idle temps are pointless, you need to know at load temperatures. Does it BSOD immediately or just after a little bit? Does it say anything like your workers are quitting on you? What clock speed are you at?
