PSU make a difference to temps?

I'm getting around 85-90c on my i7 920 @ 3.8 bundle and just wondering if a different PSU would make any difference to temperatures and if so why?

not really, unless your current psu runs hot because its inefficiant or a new one would shift a lot more air.

you'll get better results getting a better cpu heatsink in there.

I swapped from a 1100W Tagan to a 750W PC Power & Cooling and temps droped 2degC not much but it can help (the old PSU was VERY hot though).

Badly mounted heatsink or faulty CPU/mobo.

It shouldn't run this high even if you had scrap of copper attached to it and cooling it passively.

That was after an hour of Prime95 sorry, not idle!

Doesn't matter, it shouldn't be going over 60-65 after 40hrs of prime.
I would dismount and, clean up, apply paste and mount the HS again.
