just bought arctic p12 but not spinning when connected to cpu fan header even not spinning at all when start/boot up my pc tried to connect another fan to pst header , the fan connected to pst header working normally but the p12 not spinning at all, tried another fan to cpu fan header working normally it means the cpu fan header is not faulty , tried the p12 to sysfan (3pin) somehow it working and spinning tried back to cpu fan header (4 pin) not spinning again , what's wrong?? i use an old motherboard msi h97m e35 the 4 pin only on cpu fan header remaining header are 3 pin (sysfan) , bios setting also doesnt have PWM or DC option tried to turn off smart fan mode also doesnt work..im out of idea is this normal??
summary:
-tested different pwm fan connected to cpu fan header (enermax TB silince 4 pin fan) works fine
-tested arctic p12 to different fan header (sysfan 3pin header) spinning normally
- tried to connect enermax fan to arctic p12 PST header and arctic p12 pwm connected to cpu fan header , result arctic fan not spinning but enermax fan spinning
- tried reset cmos , still no results
- tried to turn off smart fan mode also no result , the fan always showing 0 RPM
