Power supply noise

[ArunprakashK]

My corsair vs450, makes a weird noise under moderate to heavy load when i orient my pv vertically. The weird part is, when I use is horizontally ( which i have been doing for about 6 months), there are no noises whatsoever?? Does this have a simple fix. ??

Is it a buzzing sound or is it a fan sound?

pretty sure its the fan. As it occurs only when place the supply facing down, and no noise when placed sideways.

When did you purchase the power supply? There's not much you can do except contact the manufacturer and submit an RMA.
Messing around with internal components of the power supply can get you killed.
