Possible PSU coil whine


Amphosis

Recommended Posts

hi, i' have a problem with the infamous coil whine noise, but i'm not sure is the psu(ax 750 gold)

 

the problem occur in crysis 3 for now and when i'm mining(maybe you dunno what i'm talking about here lol) altcoin with x11 algoritm , regular scrypt not so much

 

the strange thing is that 2 day ago the problem didn't occur with only one graphic card in the system but only when i use two of them, now it appears even in the first case(only one of them being used)

 

so the guilty parts are between graphic/mobo and psu, i'm going to replace the MB and see if the issue is still there

It's very unlikely that it's the motherboard. Quite likely that it's one of the graphics card and equally likely that it's the PSU.

 

As load changes, the frequencies of different components change and sometimes that frequency can enter into an audible range.
