Cooling and Airflow Help

[LaserDashz]

Hi,

I have a Spec-01 case and I need new fans for it as the summer heat is getting my GPU to temps of 90 degrees. I am deciding to get SP and AF fans from corsair. I want to put 1 SP fan as intake on the front lower panel for the drive bay and another AF fan as intake on the upper front panel. Both 140mm. Then I will put 2 120mm AF fans as exhaust on the top and at the rear I will use the stock Spec-01 case fan as exhaust at the rear.

Is this air flow set up correct or does anyone suggest a change in it?

Thanks

Yes, it is correct. Summing up: intake x2 in the front, exhaust in the back/top one each.

Ok thanks, but are the type of fans correct like my choice between AF and SP fans?

SP isn't really required. They are more for heatsinks and radiators. You can go ahead and use AF all around.

As for intake/exhaust. I count 2 in the front as intake. And 2 top exhaust and 1 rear exhaust. That's a lot of exhaust especially up top. The top one near the front may tend to exhaust the air entering the front preventing it from reaching the back. Having too much exhaust gives negative air pressure drawing dust into the case through cracks.

Also remember tat your video card acts as an exhaust. Also the PSU may if the intake fan is facing the inside of the case. Some better casees point the PSU fan to the bottom of the case.

Some newer cases come stock with top fans pointing in as intake. Front intake. Bottom intake. That brings massive air from top/bottom/front wrapping the inside of the case. The exhaust occurs at the back of the case with the video cards and fans. This insures that all components get some cool air as it wraps the entire case from top to bottom on it's way out the back. And with more intake it creates positive air pressure so dust is kept outside the case.

The only way to test is to get temperature readings. Then try flipping some fans, moving them around, etc... and get some temperature readings again.

Like gondo says, 2 top,exhausted unnecessary & can actually draw fresh air away from the gpu cooler.

2 x front 140mm intakes , & add a single 120mm fan as top rear exhaust along with your existing rear exhaust.

So 2 x 140mm intakes, 2 x 120mm exhausts.

Nicely balanced airflow, slight positive pressure system.
