Case Fan makes videocard overheat?
 

Hello,

i recently tried to install a case fan ( http://www.antec.com/images/400/80mm_4pin.jpg ). i placed it at the back side under the power supply, label pointed towards the outside.

after the placement my case temps dropped by 8°C, so that's good :) BUT, my videocard started to act strange, weird artefacts until the whole system hung.
i've now removed it and everything is back to normal.

is there anything i can do about this??

some info (maybe useless, i dunno)

do you have intake fans?

hi,

no i don't have intake fans, i had 1 case fan lying around which would have been the ONLY case fan in the entire system :)

edit: i figured that i should let it blow hot air out rather than suck cool air in? i haven't tried it the other way though.

Should have both intake and exhaust case fans. Likely your case has min. air flow from the front to effect vcard performance after exhaust case fan installed.

put an intake fan on the side over the vc

that seems the most logical explanation. there could be a vacuum above the vidcard so that heat builds up there.. or something.. :) i'll get a second fan to get cool air in. thanks!

this might stir up the CPU cooling, one in the front, on the in back would be ideal :)

if you use only 1 fan, put it in the back to suck hot air out of the case

i have 1 front intake, rear exhaust, and side exhaust, my case temp never goes over 25. ideally u need more exhaust than intake to make sort of a vacuum

"and side exhaust"

you're saying 2 different things here :)

ya ya, im describing what i did, since some1 else said it wud be better to put an intake at the front....which cud b true......if possible, experiment with it
