ye..its huge looks cool too

btw today i updated my bios version to fc. I had the fa version and the CPU FAN MODE Option was on PWM
But after i loaded optimized defaults that went to auto.. to be honest i don't know what those settings stand for cause there is no descriptions available :
AUTO
VOLTAGE ?
PWM ?
so i was wondering about which one is the best..?
Also has anyone noticed any differences between fa>fc version as for cpu temps?
