I was trying to see how quiet I can get my pc. I unplugged the front fan. It's 80mm and in the 5.5 bays (pics in my gallery). It's my only intake fan. Without it my temps seem to have actually dropped a tiny bit. So is it fine to have no intake? (I should mention the entire front of the case is mesh).

With intake:



Without intake:



The blue led fan that's the intake:

If your temps are still good i'd say your fine, but you may get some heat buildup while playing games without that airflow. If that does happen you may want to use that fan controller to turn it on for gaming, benchmark, etc.

I've wanted to do that, but the problem is that the controller makes the LED's on the fan not work, and it doesn't silence it as much as I'd like.

Plus I wanted to put that blue fan under my GPU, because that's where the loud fan currently is, and the blue fan is much quieter.

It was probably a fluctuation, and not because of the fan. 80mm fans are obsolete now, they don't do much.

Does it not have an on off switch? Well if not he may be right, negative pressure=FTW but idk, never tried that theory.

I think I had a pretty controlled environment going, room temps didn't change, and I gave it 10 minutes without the fan and temps don't change. And I just ran 3dmark06 and load temps seem usual also.

And I know they're obsolete, I just don't have any room in the front for a 120. I even have a spare 120 but have no where to put it.

If your room is cold enough it won't matter. The exhaust fans are still drawing air through the front opening even if the fan is off

K, is ~65F a good room temp? That's my average room temp I'd say, and the highest it's ever gotten was probably less than 75.
