PSU Noise

DWorrall · 15 Feb 2011 at 21:53

Hi guys, today my new Fractal Design Define R3 case came

. The case is really sturdy and very very silent... but now ive gotten rid of a lot of my case fans ive noticed the noise output from my PSU and its very very loud.

I dont know the make so is going to be hard to answer, but its an 850W Modular PSU and i paid quite a bit for it, any ideas on how to dampen the sound of the fan?

Lower the fan voltage maybe? I need a solution or i feel ive wasted my money buying a sound proof case.

I said i dont know the make.

Oh yeh duh me -.- lol. I'll have a look

As far as i can tell, its make is "AlphaPower"... i paid quite a bit for it though.

How much is this going to cost me...

DWorrall · 15 Feb 2011 at 22:29

Im gunna have to stick with my noisy PSU then, cant afford a new one.

Quick question, if i drop the voltage of my fan will it affect it in any way.

is this psu for the spec in your sig?

if so, you can spend £70 on this - http://www.overclockers.co.uk/showproduct.php?prodid=CA-003-XF&groupid=701&catid=123&subcat=1497

or even this one - http://www.overclockers.co.uk/showproduct.php?prodid=CA-042-BQ&groupid=701&catid=123&subcat=1083

It is but as i said i just bought a new case which cost me £90, no money at the moment. Back to my last question, will dropping the voltage affect it?

or does a PSU even need a fan?

yes a psu needsa fan, if yours does I don't know.

Didnt ask if it came with a fan, i asked if it needs one. :/

Yes, and he answered you.
"Yes a psu needs a fan"

He changed his post.

Fair enough ill have to save up. Be a while i just feel like ive wasted £90 on a case that isnt doing its job.

a case can only be as quiet as the components you put in it.

unless you completely seal it and soundproof it then noise will always escape.

I know, i have 1/3 of the fans now as my last case so ive only noticed the noise from my PSU today.

DWorrall · 15 Feb 2011 at 22:56

Thanks for everyones help, i might replace the fan with a lower RPM one. But i'll most likely put up with it until i can afford a decent one. Im sure OCZ or corsair should be good.

i think you may find that the fan cables will be soldered to the pcb in the psu

I'm good with a soldering iron.

Lol, but i'll just end up buying one. Saying all this, it has cut the noise a bit. But not as much because of the PSU.

Seeing as im on a next-to-nothing budget, i mayswell ask... Anybody got a silent PSU going spare?

Also, are these as silent as they make out?

your attitude and tone stinks, I am surprised anyone is helping you quite frankly

You wasnt here at the time. He changed his post, he originally said "PSU's generally come with a fan" or something along those lines.

Honestly get that XFX psu, it's so damn good and the price for it is one of the best i've ever seen for a psu of it's quality.

I wouldn't even use that alphapower psu if i were you in a pc like you have....all your components could die if it blows whereas a decent branded one wouldn't do that if it died.

This? http://www.overclockers.co.uk/showproduct.php?prodid=CA-003-XF&groupid=701&catid=123&subcat=1497

For any PSU im gunna have to save. Ive had this PSU a while and its not blown so im sure it will last until i can get a decent one.

Mind you, i might ask at college thay have a few corsair PSU's lying around.
