How much airflow you have originally anyway. And no, I would keep your side fan as an intake, directing air toward the graphics card, in order for the graphics cards fans to ingest the cool outside air and efficiently cool the card. https://www.maketecheasier.com/intake-exhaust-fans-airflow-desktop-pc I was thinking maybe it's battling the air and I can get lower temps. I never thought about this until I wanted to add 2 intake fans on the bottom of my case to potentially keep my GPU cooler but I realised I dont really know if the GPU fans are intakes or outtakes. You also want to match the CFM – that's the air flow rate – of the intake fans to the outtakes. The top fan is an exhaust and bottom fan is an intake. Members Profile.

If plenty, you could get away with Exhaust with little trade off. Better as Intake, simply because most GPU have more issue with heat management than the CPU, and often yields more noticable results from a GPU boost than a boost on the CPU from extra cooling. The additional exhaust fan made no … Reference coolers blow air out the case - but not very well. Of course there’s the CPU and GPU coolers as well as the PSU playing into it. This can be creatively modulated by CFM rating of the fans youre using. First, if you can orient the power supply so that it exhausts it’s heat to directly outside the case, that will be better. Your negative pressure graphic is not likely as you would never exhaust out the front. A blower GPU design covers these fins with plastic. GPU fans grab air and push them into your heatsink, which then blows out the sides of it.
