hi,
my 6 month old GA-P55-UD2, i5 750 3.36ghz (29c-50c), Corsiar TX 650w, XFX 5850 XXX, 4 pin H50 (800 idle), 3 pin 1x120mm sys (675 constant) fan is pretty quiet.
Smartfan on "AUTO".
But sometimes I get a low whump-1 sec- whump noise. Snowed in the town is quiet so started to fiddle.
Tried speedfan but didn't work (smartfan off). Hoped i could also switch of each fan to isolate.
Read about PWM phases. So tried Smartfan on "voltage".
Sys fan is up to constant 695rpm
H50 is down to 480 on idle. Even got 0 when PC was cool.
temps around the same. Used Prime32.
Half an hour, no whump-1 sec- whump noise so far.
It sounds that running H50 on "voltage" is fine. Correct?
