Which way should my fans be facing PC?

When mounting case fans, air flows across the open side towards the side with the protective grille, like so: So the open side of the fan should face outside the case for intake fans on the front or the bottom, and it should face inside the case for fans on the rear or top.

Is positive or negative airflow better?

Positive – there is more fresh air coming into the case than there is hot air exiting the case. Basically, the CFM from intake fans exceeds the CFM from exhaust fans. Negative – there is more air exiting the case via exhaust fans than fresh air entering the case via intake fans and vents.

What’s better 3 120mm fans or 2 140mm?

Generally speaking, with airflow equitable, the 140mm will be spinning slower and quieter. However, most 120mm will spin at max faster that a 140mm, so 3x 120mm can put out more cfm, if barely. Mostly it boils down to aesthetics.

Is negative airflow bad for PC?

Negative air pressure is where you have more air being pushed out of your case than sucking it in. This causes air to be sucked in through gaps in your computer case, which can pull in dust, dirt, and hair. All of which are bad for your cooling situation.

How do I cool my GPU?

1. Vacuum the dust from your case. If your computer’s case is filled with dust, cool air cannot flow in and hot air cannot flow out.
2. Add another case fan.
3. Install a PCI fan card to blow on your graphics card.
4. Add an aftermarket GPU cooler to your graphics card.

Which way should GPU fans face?

At idle they normally should not be running, but running the fans constantly should not be a problem for the longevity of your gpu fans.

What direction do GPU fans spin?

The gpu fans blow air toward the heatsink, which then exhausts in all directions. It doesn’t matter which way the 212 evo is mounted, but I would recommend having the fan blow air through the heatsink rather than suck through it.

Are 140 mm fans better?

They boast several impressive features, including noise levels many users would consider acceptable. However, the 140mm fans’ sleek performance makes it noteworthy. With better noise levels and airflow, the 140mm would be more superior.
