Putting fresh air into a GPU can really help drop it's temps in my experience, imo they're kinda crap at in taking air on their own.
Well I really dont like the idea of cutting my case, but adding an extra fan is nice though, my front intake fan is quite weak.

Both of us have the same case (Elite 335)

I will post the result soon.

OK so here's the result

Furmark 5 minute benchmark

With fan


Without fan


Honestly I'm not really happy with the results, anyway the extra fan makes my system looks better (the only LED fan)

If the fan was setup as an intake, try the other way around (ie exhaust) to make the picture complete.

OK, I will do that

but it will take a while for me to change the direction of the fan, will post the bench result later~

Setting the fan as exhaust did drop the temp by a bit



So I'm quite happy with the fan as exhaust

hmm interesting, okay, I might get another fan and set it up as an exhaust, what kind of fan did you use?

we actually share the same idea i put a 80mm fan on my PCI slot as Exhaust
as i know exhaust would be better than intake..



so i also did a little experiment with my side panel fan.. since it is Meshed i didn't know
which would be better intake or exhaust.. hope this would be relevant here



i used furmark 1.8.2 Extreme Burn-in w/ Post-FX on my 6879 OC to 1000/1250 @ 1225v
pls. bear in mind that i leave somewhere hot in Asia so my temps would be kinda high..

btw i used a 120mm OEM Everflow fan 2.7k RPM 110cfm as a side panel fan which
is kinda loud but moves a lot of air..

side panel fan set on Intake 10 min furmark



side panel fan set on Exhaust 12 min furmark



temps differ 2 to 3°c so set my side panel fans now on exhaust..

well for you an exhaust in the back is better since your psu is in the bottom and intake would just suck in the hot air so exhaust is a better idea

Do you have your side panel fans as exhaust or intake?

does the side fans have that much effect on the temps? i have a side fan on mine as you know since we have the same case. I switched my 2 side panels so my air flow goes straight front to back. So I was wondering if you can test the temp differences. and what fans did you use?
