omgggggg I never knew that ?

I always thought it pushed out hot air facing from the fan... ?

The "open" side of the fans (the side that does not have the blades obstructed by the frame holding the motor) are the intake side of almost all fans universally.

Hey everyone,

So I was planning on building a new PC in the ITX form factor and when I was looking for a case I decided on this https://www.newegg.com/p/2AM-000Z-00051

It says I have room for two 120mm fans at the bottom of the case under the GPU, but I was wondering wouldn't it create negative airflow? If the GPU is exhausting hot air and the fan is taking in fresh, wouldn't that suffocate the GPU?

Here's a pic for example https://www.dvhardware.net/news/2019/lian_li_tu150-2.jpg

If it were a blower style GPU I guess it would be ok, but I plan on keeping my EVGA GTX 1060 6gb, so it would be blowing air down.

If I'm just not understanding something any opinions are appreciated!

GPU's intake air from their fans and push it out the faces as exhaust. It would not suffocate the GPU.

NO

You have the privilege to have 2 bottom fans, they should absolutely blow air straight on the GPU...
