Hi! I am living in Shimla,and it's really cold here.my 3(SMPS,processor & one for whole cabinet) PC fans make a loud noise.I am thinking of disconnecting one manually(not the one of SMPS surely! ).Is there any need to keep all 3 buzzing in such a climate? Which one I should disconnect,the one of processor or of cabinet,or both? Idon't know how to disable them through BIOS,so I'll be unplugging them from motherboard,so pls help me!!
