For quite some time I own an Arctic Cooling T2 case and really enjoy the new-found silence when working with my computer. However, this silence has been disturbed by my recent acquisition of a Matrox P750 (see Finally) and this little screamer here:

It took exactly half an hour to decide that the noise level is unbearable, so I got myself a Zalman ZM-80D-HP:

I read on a forum that with the P750, There is one slight problem, though, and I am wondering whether this is normal. Instead of everything lining up nicely, so that the heatsinks are all square with the board itself, they are slanted somewhat (I would guess 10 degrees maybe).

Turned out that this is true, thanks to some screwy decision by Matrox to not place the heatsink holes where they are supposed to be:

That way, the whole construction looks weird at best (no, I haven't been drinking while composing this monstrosity), although it is fully functional:

Fully functional meaning "Ah, the silence is back!"
