Too bad i dont have any pictures. But a few of my onboard fans have been failing lately. So what do i do? I strap a 80mm fan on a 60mm heatsink with some duct tape (of course making sure its nice and tight ~.^) and its been doing pretty good so far. AND! Since my videocard fan pretty much failed i yanked it out of there, strapped a 80mm fan on the side door and have it blowing right on the card and wala. I have a computer that no only performs better! But runs cooler.
Not much, about two degree's celcius as i had a pretty strong 60mm fan it originally. But it is quieter.
You should duct the fans onto your heatsink and gpu. That way they blow more air onto the sink and gpu. Like this, they'll probably blow like half of it past the sides of the heatsink and gpu... P.S. It voilá, not wala
Psht, Viola, Wala..whatever. And the fan is ducted to the heatsink with electrical tape and duct tape ^_^
