Poor circulation under my graphics card. How to improve?

They have expansion slot coolers you could put into one of those free PCI slots and use those as an exhaust

I dunno about an exhaust fan, wouldn't that just play tug-o-war with my graphics card fan? It points downward and sucks air upward into the heatsink. An exhaust fan would pull air downward and away from the graphics card, wouldn't it?

As for the air filter--, would that be a cheese cloth or something like that?

I just had another idea too, what about putting a "snorkel" over the vent so the air intake is higher off the floor? It would probably be pretty stupid-looking, though, and I don't know exactly how I'd make it.

There are some things you can try that don't involve a lot of cash or modding. EG, you could temporarily mount a small fan (you might have one laying around) inside the computer case, "below" your vid card, and pointing at the back of the case (the two remaining expansion slots). Then remove the slot covers to provide a vent. If your case has enough incoming air, this fan would blow the hot air out the now-open expansion slots.

If that works, you could then mount the fan to your case's side cover in roughly the same position - double stick tape, velcro, whatever without doing anything to your case.

A bit cumbersome when you remove the cover, but if that's a problem find a way to screw the fan to your case's side cover. (L-brackets)

If that doesn't work well, position the fan against the two open expansion slots for a more direct exhaust.

Otherwise, you could buy a slot cooler and try that.

Okay, I remembered wrong, sorry. There's only one free PCI slot under the graphics card, since the cooling system takes up a two slots' worth of space. So there's really not much room underneath the card.

I do have an extra 80mm CPU fan I'm not using, complete with home-soldered "extension." I had the idea to do something like this with angle brackets, inside the case:

This is definitely NOT to scale, because my memory (as in, memory in my brain) is bad. If I actually did it, the fan would tower over the card, which is only an inch or two off the bottom of the case. Still it would force some air underneath the card. Anyway, an exhaust fan in that limited space would be out of the question, as it would fight against the graphics card fan.

Remove the metal slots below your Video card where you would normally put more PCI-e devices. That cooled my video card down a hell of a lot.

i would use a tools and cut out part of the side of the case for air intake for a side fan

Thanks for all replies.

I hope to get as many opinions as possible before making a decision.

I'm the one that posted the link to that cooler lol

You have a vga card that does a good job of getting heat off of the vga chip, but it then dumps it into the case where it can recirculate. Not very good in a small form factor case.
You need to get that hot air out asap. The slot coolers mentioned that exhaust air should help. Can you increase the cfm of the intake and output fans in the case to create more flow?

Another option is to replace the stock cooler with a dual slot cooler that sends the hot vga air directly out the back of the case.

Would you consider replacing the 4850 with a card with a good shrouded dual slot cooler?

from what i see, that card isnt pumping air out, just venting it.

thanks for posting that link it really makes sense now, u need to open ohe expansion slot below the 2nd 4850 slot so new air can come into the fan, also ur case has to have a really good exaust system, i actually cut a hole in the top of my case and put a 12cm to suck air out, but a rear fan can work just as well, if theres a grill behind ur rear exaust fan, remove it the air will flow out more freely.
