Noise of Fan from PSU

[kg11sgbg]

Recently,my Aerocool PSU (E78-530)has started a whinning noise on its fan,when I start the PC.Though the noise subsides gradually,and eventually everything seems to be running smoothly.
The noise comes out from other cabinet Fans,with a low sound and the Aerocool Fan seems to synchronize its sound with them.

Do I need a replacement of PSU now?

Or shall I run the system for some more days longer,before buying any PSU?

This is my query.

Its better if you replace the PSU fan.
Buy any 120mm fan and replace it.

First clean your PSU and system properly. maybe dust is accumulated so fan is not functioning properly. If this dies not helps then do as d6bmg said.
