Swap top fan for intake rather than exhaust?

post #1 of 26
Thread Starter 
Here's a diagram of my setup right now.

Should I swap the top fan for an intake instead?

How about the H70? Do you think I should make that an intake instead?

Shouldnt your side fan be set up for intake? that would work the best if possible
post #5 of 26

In your case, yes, I would recommend the top fan as the exhaust... I actually have the 300 as well, and the temp difference was non existent, with the front fans on medium...

However, some cases do benefit from direct cool air from the top... Like my HAF-X...

Depending on your setup, it can actually hurt the temps since the hot air exhausted from the back will rise to the top, and will be sucked back in from the top fan...

When thinking in terms of heat let's remember where that hot air wants to go and where it's going to come from. The BEST way to vent out hot air, which, as every 5th grader will answer both on TV and off is going to rise, is from the top of the case. Very few fans are going to be able to prevent heat from migrating to the top of the case somehow- even if heat is all relative. If you put 5 degree centigrade air in your case, the air that warmed up from being exposed to your components would rise and the cooler air would drop.

I think we've been over this once before. MOST H70s will actually benefit from drawing in cooler, outside air- unless of course your ambient air outside the case is warmer than 30+ degrees but I doubt it will be. So best to have the H70 as an intake. Equally, the warm air in your case is going to migrate to the top... so best to keep that as an exhaust.

Given the limitations of the Antec 300 and the fact that you have an H70, I agree with this.

Right, I'll try out the H70 as intake.

Also, since my GPU is just a bare heatsink (blows hot air all over the case) and not shrouded, when I had the side fan as intake, my GPU temps actually got worse than with no fan.
