Hello ! Today I bought a Fortrek titan dark knight pc case. After changing my pc case with this one, everything works fine except my cpu fan. I've ran my pc for about 2 hours and thought it was normal for the fan to spin that way, and after those 2 hours I couldn't hear that noise anymore. It is spinning very very very loud and fast at the speed of 33280 rpm. Yes, 33k rpm !! ( I used cpuid hardware monitor because no other program can detect my fans ) Printscreen here : Usually when I power up my pc the fan is silent but after 15-20 secs aprox it starts to spin like hell. I tried to lower the speed through speed fan but it won't detect any pc fan, it's all empty. I tried to lower it through bios, but I couldn't find any fan speed setup (windows 10). At this point I'm even afraid to power up my pc because I don't wanna break any of my pc components.. My cpu : intel i5 2400 3.1 quad core Sorry for my bad english. Any idea ??
