Not really a problem as I am typing on this PC as I sit here but I have recently purchased a new video card since my old one crapped out and the new one is the BFG gts250 oc and it is a bit long but nothing the case can't handle but it comes right across the little motherboard fan and makes a kind of buzzing sound, now I have checked both the vid card fan and the mobo fan and both are fine. I was just wondering if there was a safe way to put something between them to make the noise stop.

Thank you
 
That's odd. Normally the CPU is installed on the motherboard far away from the card slots...

I've seen little fan covers that re-direct the air flow. Might be a good idea so each fan is getting fresh air.

You can also replace the stock CPU fan with one that stands upright. Might or might not help in your case.
 
The rear of the video card is across the top of the fan? If the fan is hitting the videocard, I don't think putting anything between them will help. You can try to find a thinner fan or get a different video card. I suppose that you could try to sand a bit off of the bottom of the video card where it is hitting the fan, but obviously this could have unintended consequences.
 
it is the square object behind the blue PCI E slot and to the left of the RAM slots amd it says Asus.
 
Is it the biggest fan on the motherboard? Is it rubbing on the thin (closest to the motherboard) part of the video card or the side?
 
If it's rubbing the heat sink I'd just try to bend or file it so it doesn't touch. It shouldn't hurt anything, though I'm sure it would void the warranty.
 
That's an interesting motherboard - never seen one with a fan in that location.

No it is rubbing against the big aluminum heat sinc on the video card.
Its the big thing on top with the guy.

I wonder if the large aluminum plate is really a critical heatsink? It may merely be a plate to direct the air flow over the card. I'm reasonably confident you could use a Dremel to remove the offending portion of the graphic card cover without affecting performance or cooling. Of course, as mentioned above, I am sure that would void the warranty.

I have put a little slip of paper and that seems to keep it quiet sometimes.

A piece of foam/silicon/rubber weatherstripping would probably work better than paper.
 
The A8N SLI is notorious for its poor northbridge cooler. Some people have managed to fit zalman passive coolers onto it, but that would not solve your problem because a passive cooler is taller to make up for it's lack of a fan. the Nforce chipsets tend to run warm, so removing it would not be a good idea. Is the noise the result of the vid card and the northbridge cooler vibrating against one another? if that is the case then as some have mentioned you could simply insulate them with some foam. It may be that your northbridge cooler is going bad causing it to vibrate and make noise, in which case you can contact Asus and try to get a new one. Or it may just be time to move on from socket 939 to bigger and better things, think LGA 1366 :D

Guys thank you I have just turned my PC back on after slipping some foam from the pistol case that came with my S&W M&P between the video card and the fan and it is now totally silent, and Sevorius (cool name BTW) I do plan at some point to go up to a nicer machine but the parts that I have right now where awesome some years ago.

AMD athlonX2 3800+ 939pin(with a large Zalman proc fan with green lights)
Asus a8n SLI
EVGA 7800GT 256mb (old video card)
BFG GTS250 OC 1gb (new video card)
2gb Kingston hyperx 3200
Antec Truepower trio 550
Thermaltake Shark case
Creative X-Fi platinum
Plextor DVD burner
Linksys wireless card

So I have good parts and the video card is the only thing that has broken in the last 3 or so years and for what I am doing right now, not so much PC gaming but maybe again at a later date. But at a later date I will upgrade my PC when I get the money and it will be a powerhouse again.
 
Oh yes tools involved in the process of foam insertion
Cold Python 2 SE (to cut said foam from pistol case and cut foam clipping in half)
Plastic toothpick from a small SAK (to help push the foam between fan and video card)
Surefire E1B (to light up the case to push the foam between fan and video card)
And my hands (to manipulate the tools above and pat myself on the back upon hearing that the operation was a success)
Oh and God because he makes all things possible.
