Just curious how you all would set up a tower with 4 fans.

I fired up MS paint and did a back, side, top veiw of my tower.




What will give me the best air flow??????

Forget the fan at the top, just add ventilation for the heat to escape. I would put one at the back, one on the side over the processor hsf, and two at the front for intake.

personally, i wud prefer having positive pressure inside the case (less dust gets in...supposedly if u use air filters over the exhaust) so i wud put 2 intake at the front, one at the side, and one at the back for exhuast. this is assuming ur using 80mm fans . if you have the option of using 120mm fans, i wud suggest doing what i do : 1 at the front as intake (covered with air filter), 1 at the side (air filtered) and one exhaust at the back.

back sending air out of case, top sending air out of the top and side sending air into the case.

There is no space on the front for a fan. I have 4 fans to put in ( was going to filter intake)

Will the one side intake feed 3 exhaust? Or will air enter from other areas to make up what the one fan does not push?

Sorry to go off topic, but Greywulf, looks like we have very similar cases. :D As for the cooling system, I've OC'd a few times, and all I have for fans on the case is the one on top and side, both outtake. Now that I come to think of it, no fans do intake (exept the one on the PSU. And I have never seen my sys monitor anywhere near the danger level.

if u are indeed stuck with that fan config, then following cooliscool's colouring wud be best i think....cept to reduce noise and add positive pressure, make sure the top fan is slow (doesnt need to be fast anyway) and the rear fan is not as powerful as the side fan...

thats true, but its being dragged in through the holes in your case where theres no filter....its not a bad idea (i had this config in the past) but ends up making your computer a lot more dusty. right now with my 3 fans i have positive pressure in the case and (before air filters were put in place), temps are cool and dust goes out from the holes where otherwise it would be coming in >_>

your choice really what to do o_O"

The best way is to have the total amount of air going out be the same as the air going in, negative pressure can cause dust buildups and possitive pressure can cause evecsive noise

IMO cooliscool's and Aided Onslaught's ideas are both wrong. First of all cooliscool you are just turning your airflow into a big mess that is going in all the wrong directions without any efficiency at all with thoes back fans going opposite.

Aided Onslaught if you were a heatsink and was friggin hot; would you rather have hot air pulled off of you, or cold air blown onto you? Therefore it would be best to pull as much cool air in as you possibly could.

I would want one fan on me...(like I have one fan for my cpu and one for my video card. Well two if you count the one on the video card.) and then more fans pulling that hot air out of the system.

Be careful with front intake air fans. They can cause the air to pass over the hard drives and then blow hot air over your components. Which can tend to be counter productive. My cooling solution is pretty simple.

One intake on the side and the PSU Blowing Air out. I have tried 3 others configurations with fans and none of them have been as effective, ((or quiet)

goodness....thats what i get for working 14 hours overtime...i thot the two at the back were for exhaust O_O.

possitive pressure can cause evecsive noise
which is when u get bigger fans that rotate slower and have less noise...or just get slower fans in general ...

indeed...again i forget to mention that i have only 1 hd and that hd is located in the highest HD bracket in the case so that only the bottom part of it grazes the airflow. if you have many, it might be in your best interests to invest in a (few) hd cooling bays or what not if you dont want to cool your harddrives with a front intake fan (in which case if u just leave them there with no cooling ur risking shortening the life of your drive iirc)

I removed my front fans because of both the noise and dust. My hard drives would just colect it. The noise was cut almost by half and temps lowered about 2C. Later on I cut my fron fan grils out since I have a cheif tech and you can't see in there anyhow. and I cut the back ones out too. I notice a little difference with that.
