Whoohoo EP^^

It's me again with my heat issues.... while I finally managed to keep my CPU cool, this time it's my Graphics card who is getting loud...
It's a XFX 5770 and looks like this:





I cleaned it as much as possible from the outside but it still idles at around 75°C with 55% fan speed, which is still at acceptable noise levels for me, however as soon as I open Firefox 4.0 with hardware acceleration it rises to 82°C with 60% which sounds utterly annoying. I confirmed it's not a Firefox issue as this started a few days ago and I reverted back to a 2 week old build, still the same. Plus I'm sure when I got it in May/Juny it idled at 55-60°C

So yeah I wanted to ask, has anyone experience with removing the plastic housing? I don't want to remove the entire fan if possible as I... well lets say I have a few bad experiences with applying thermal grease myself... Just removing the plastic housing for cleaning would be enough.

I looked at the bottom of the card and there are quite a few screws I just don't know if I can remove them all without making the GPU loose as it's attached to a clamp.

Thanks for any help in advance!

Thanks guys!^^ Funny stuff... it wasn't dust, I found out it was a software problem.... apparently, having the same FullHD monitor connected to VGA and HDMI and duplicating the image on both outputs causes a massive heat rise

Oh well, she's back to normal again^^
