Exhaust or intake?

[S7117]

I bought a h100i gtx water cooler and want to know if I should sit up the rad as an exhaust or an intake?

Is there any performance difference for intake into the case vs exhaust out of the case?

Note: I have two 140mm AF140 corsair fans as intake in front and a af120 in exhaust in the back. I also want to have a positive air pressure in the case to keep dust out.

Thanks!!!

exhaust it because it just dissipates heat better. if you intake some heat gets blown into the case more then usual but that's just from my experience

If you want a positive pressure, then install your aio as intake

maybe turn the fan in the back around so it is an intake, and have the cpu cooler as exhaust. You wouldn't not want the cpu cooler to dump hot air all up in your grill...

I do have two 140s in the front and a back af120 in the back right below the aio... The case is a corsair 450d

and change your rear exhaust fan to intake and be sure to get a dust filter before doing it

exhaust because you're trying to cool the radiator. and intake makes no sense as you're putting hot air back in the case.

You should install it as exhaust, u will get a neutral or slightly positive air pressure. BTW the hot air goes up because is lighter than the cold air, it would be controversial to set the top fans on the case as intake.

Thanks everyone!

Intake

Benefits:

Positive air pressure prevents dust from getting into the pc

The CPU will be slightly cooler as the radiator gets fresh air.

Negatives:

Other components in the pc if it doesn't have good airflow will be a lot hotter.

Semi Passive GPUs are gonna spin up earlier.

GPU overclock might be hindered.

 

Exhaust

Benefits:

Hot air gets quickly sucked out of the case making everything slightly cooler.

Negatives:

Negative air pressure gets dust sucked into the case.

CPU will run slightly hotter.
