so i'm hoping that i can get some opinions from you intelligent people in here.
situation :
friend says that his system is now reporting low chassis fan speed when it was fine a few days ago.
original fan speed was reported to be roughly 770rpms, and is now being reported as 570 *giving off a fan speed warning* ...600rpm is the set limit before warning.
he made sure to check for any dust build up, btw. seemed to be fine.
he has an Asus p8z77-v lk motherboard with Qfan enabled. he says that the Standard setting gives him 570rpms, and the Turbo setting gives him 590rpms.
he bought a new fan rated for 950rpms, put it in there, and gets the same results. (new fan is Kingwin 120 mm CFBL-012LB).
so i find that somewhat interesting. any ideas?
i mean, he could try a bios update maybe ...and that might help, but if the fan was reporting higher speeds a few days ago, and is reporting slower today ...something must be up, no?
