"System exhaust fan.."

I've bought an Exhaust fan due to the fact that it's getting hotter and hotter and that will obviously sit in a spare PCI slot but I'm not sure where it is best placed?
I have one spare slot right next to the Radeon and another after that.

Normally its best nearer the top as heat rises but make sure it does not disrupt the air flow within the case.

Yea I just want to take a bit of the work load off the case fan.. might be a good idea if I placed it next to the graphics card.

well if it one of the fans I am thinking of [URL]http://uk.special.reserve.co.uk/q_GG1664_slot_fan_for_pc_1_.html[/URL] air blown down from the graphics card can then be chucked straight out the back of the pc

Yea exactly rather than it having to be blown out through the case fan.

I would mount it one down from the graphics card, as at that range both fans will work against each other - and the extractor will probably win, eg. cooler air, but less air pressure around your GPU. Give it a slot's space and you'll have a nice pressure gradient in the middle of the exhaust and GPU, so your GPU fan will have a nice supply of fresh, non-competetive air.

So your saying I'd best put it in the slot next to the GFX card, but putting it another slot up would be just as good?

Yeah. I guess the only real way to know is to test it.

Also most of these exhaust fans actually have the fan on the under side so putting it next to the Graphics card will only give it a barrier, you would probably be better off putting an 80mm fan in the front and back of the case and have it ducting like that. i found the PCI exhausts not to work very well at all.

I'm not to sure as one I had (which burnt out after a while) I could unhook the exhaust and turn it over.
