Hi Folks/Girls/Guys/Gals/Aliens,

I'm ordering my new set up tomorrow but want advice about whether to have my side fans as intake or exhaust.

The case is a Corsair Vengeance C70 Midi Tower Gaming Case http://www.overclockers.co.uk/showproduct.php?prodid=CA-067-CS&groupid=2362&catid=1489&subcat=

It will have Akasa Apache Black Ultra Silent AK-FN058

2 as front intakes, 2 as top exhaust & 2 on the side panel which I was going to have as intake but wondered as I'm having a Gigabyte Windforce 3x 7950 gfx if they would interfere with the airflow on the gfx that already has 3 fans on board.

I definitely don't know much about fans so would like advice.

Reading around a lot of people recomend side to be intake to blow fresh air to the gpu. If your worreid about exhuasting the hot air from within the case thats what the top 140mm fan is for as heat rises to the top. Hope all is answered :)

I just ordered my second akasa apache today:D Very good fans.

Try it both ways and see which works best.

Here's what I found when using a custom cooler. Perhaps results would be different when using case mounted fans, perhaps not :)

Look at the light green and the gold bars.

LATE EDIT: VRM1 Temps were eventually reduced by around 10°C by using the large Alpefohn heatsink with the thermal glue.

Tbh, with your card it may even work better with no side fan at all.

Heat rises when airflow is stagnent (no fans)
But i agree with the side being an intake. But may make no difference anyway.

Air should "flow" through the case, having fans in all directions could hinder this, probably have to compensate by using brute force, ie turn the fans up which inturn creates noise, best way like petey is to experiment.

In that case, looking at the C70's side fan options, I'd say not to bother.
The top position would be directly on top of the CPU cooler if clearance allowed. This wouldn't really help whether intake or exhaust imo.
The bottom position would more than likely increase turbulence around the GPU fans and possibly hinder their performance if set to intake. If set to exhaust, it may well compete with the available air being drawn by the GPU's fans.

So yeah, I think you may be right in thinking that they'd interfere with the GPU :)
Agree with Nicko, leave 'em off and keep the view intact :D

Ed: Also note in the above barchart how side intake increases gpu temps compared to just having bottom mounted fans.

Thanks for advice.

I think I'll leave the side fans off then.

I can always get some help in adding them at a later date I guess.

Now going to bank to move money so I can order rig today.

Although they will work, wont both pairs have to be matched to realise there full potential in x79?
I'd of recommended some sammy greens, wont see them under that big cooler and if you wanted to have a play(OC) i'd imagine they'd have quite a bit more headroom.
 
I have an apache fn-062 side intake, when I get time I'll do a heaven run as intake then again as exhaust and post the results.

120mm fans = Gentle Typhoon 1850RPM
140mm fans = Akasa Apache AK-FN062

set up like this:
