This isn't really a huge problem, but defintly bugging me. I have a exhaust fan in my case of course and recently purchased the Gigabyte M61P-S3 motherboard. Works fine, no worries...fans working too. Just noticed the other day in bios it says "Sys_fan = 0rpm." meaning it's not detecting it, but it's detecting the cpu_fan. Is it possibly because it's only a 2 pinned fan and not 3 or 4 pin, any help appreciated!
