hey, so like I replaced my cpu fan with an older computers fan that worked perfectly, everything is fine now but it's really loud and gives me a headache. I'd like to lower the fan speed, it's currently at 4500-5000RPM and is insanely loud (It is pretty old but atleast it survived longer than my dumbass 2 year old current computers fan). I've tried SMART Fan in BIOS and Speedfan, but neither seem to do the trick (Maybe I'm doing it wrong?) The fan is a 3-pin connector and connected into what is I believe the CPU fan plug/header/whatever its called. Incase anyone needs my specs: MSI 760GM-P34 (FX) mb AMD FX 4300 MSI GTX 650 1GB 8GB DDR3 RAM - some random old asus fan covering the cpu, temps look normal.
