I built this PC about 2 months ago, but recently the PSU has been getting
noisier. It emits a constant 'whine' that changes depending on cpu load.
The changes in noise are particularly obvious when using the scroll wheel on
the mouse. Oddly, if I disable the AMD 'Cool & Quiet' feature, the noise
disappears, but the processor then runs very hot. The 'Cool & Quiet'
feature drops the clock speed and voltage when idling, keeping the processor
cooler, like variable underclocking. So the noise appears when there is
less load on the PSU!
The PSU is a good quality model, but I don't know if a replacement would fix

Are you _sure_ it's the power supply and not the
A replacement could easily solve the problem but the odds
are better to choose a different brand. Not that there's
necessarily anything wrong with that brand (that I know of)
but if it's design combined with your ambient temps and
system load are causing it, the best best is a different PSU
make and/or model.
