How to make psu quiter

[Switch 82]

Hi all

I've currently got a cooler master 650w psu in my pc but its running really loud, always has done. is there anything i can do to quieten it down (in settings etc?). I'm mainly asking because i'm going to upgrade my pc after xmas but dont want to go an buy yet another psu just to have it as loud!

Cheers

so which one's would u suggest, i need as quiet as possible. doesnt really need to be stupidly powerful either as i only use photoshop, dreamweaver and football manager on it!
