So top case fans are better as intake or exhaust?

entirely depends on what case you have, what fans you have installed, and where the case will be located.

As long as heat still rises, exhaust.

So are you guys seeing reduced temps by just removing the grid behind the rear exhaust fan?

hell yeah, dropped temps by 2-4°.
since its ridiculous cold (and my ambient varies) here at the moment i cant tell you the exact value but the air coming out feels like twice as much. its worth it

as long as you don't have a roach problem:D the grill is there to keep things out of your case whatever they may be, but mainly fingers and roachs:D
post #757 of 2110
I have a finger guard over my rear exhaust where I cut the hole so mothing really gets in
also for top fans, it depends, hot air rises doesn't make a bit of difference when it comes to fans, you would have to test it out yourself, one time I had the top front intake and the top rear exhaust

I'll admit I didn't cut that one, but you can see the effect of an open space and a finger guard.

 

Here's an earlier case:

Oh yes: hot air rises, but even a weak fan is much stronger. Bringing air down from the top of the case presents fresh air to the heatsink and keeps the gpu's hot output from rising where it can be ingested by the cpu cooler.
