Antec 900 Fan configuration

Ok so im using the antec 900 , and currently have two intake fans in centre and bottom , with another fan on the inside centre , an outtake at the back and a 200mm top outtake fan (which draws out virtually no air , im guessing its due to the Zalman). Atm the front 120 mm intakes are blowing on the bottom of the case i.e. the PSU and bottom of the motherboard , and the other intake directly on the GPU. I was wondering if anybody else with this case uses some other configuration / layout. I was thinking moving the bottom one to the top which would blow air onto the CPU .

The 2 on the bottom blow in, 1 in the back blows out, and the top one blows out as well.

That's your best configuration for positive airflow.

The 200mm fan DOES daw out air, it's just that it's a slower rpm since it's larger, so it gives the impression it isn't moving very fast.

Ahh i see . So two front at the bottom rather then at the top blowing on CPU would be best? Also what about adding one on the side , would it make a lot of difference or would it just interfere ?

Your not going to see much change blowing it at the cpu considering you already have heatsink with a fan on it.

I would not put a fan on the side, that's just going to screw your positive airflow.

I'm guessing your having temperature issues?

Erm im not sure but i was looking to OC'ing some and i think my temps are waay too high :

Those temps look fine, Mike. Is that under load or at idle? Chris.

They have to be at idle.

You also have almost a 10 degree variance in your cores. Time to reseat your heatsink.

Actually yer it is looking a little "eskew" :P also culd do with a really good dusting :P Ill give it a good going over when i get time this week . Will i need to completly take off the Heatsink clean it , reapply Thermal paste etc. ? or can i just adjust it from where it is now ?

You can try blowing out the dust from, if that doesn't work, which I don't believe it will, then you'll have to take it off and reseat it.

lol yer i kinda tried blowing out the dust but theres actually like...a layer of it now . i cant see the copper thats behind the fan its all dust. After 3 months i kinda expected it but still its a crazy amount. But anyway once its seated correctly (hopefulyli wont need to take out the motherboard to do it ) and dusted it , what woudl you say about overclocking with these temps?
