It's likely to get hot and go pop! and take some other components with it. Sorry but the PSU is not worth scrimping on. Live with the noise or provide more airflow to or around the PSU.

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 needs a fan, if yours does I don't know.
It may have a 850w label on it, but its real power is probably closer to 350w.
Its very similar to cheap hifi brands when they rate their systems using PMPO instead of RMS power.
Didnt ask if it came with a fan, i asked if it needs one. :/

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.
Cheap PSUs tend to use a fast noisy fan to compensate for the lack of heatsinks to keep things cool. Removing the fan will be a very bad thing as it'll warm up and go bang. You might be able to swap it for a slower speed/better fan with a simple but slightly dangerous fan swap mod.
Mind you at the power you will be drawing with your AMD and 5770 will be low enough that even if you halve your fan speed it'll probably still be fine.
Oh wait the installed fan is 13.8cm. Fail. I suppose you could add a resistor in line on the positive power wire.

Me? never.
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.
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.

I would suggest you do not mod a PSU at all.
I suggest you purchase a good quality unit.
I am the buyer for PSU's at OcUK so I would hope I know what I'm talking about.

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?

I haven't heard one but I really doubt if they are. If you want truly silent you'll need deep pockets for the top line Seasonic or Corsair series that only spin up their fans when at high loading.
The fan swap mod I mentioned would only be a temporary solution to save your immediate sanity, you'd need to get a decent unit eventually. I nodded my OCZ SXS1 unit because I felt it was too noisy in my P183 rig. It now spins at about 1100rpm rather than 1500rpm and is still the noisiest component apart from the loaded graphics card.
