I’m thinking of adding more fans to my system, to cool my GPU and more importantly in controlling the amount of dust getting in to my pc case. Thus I’m hoping to set up a positive air pressure with more intake airflow than exhaust.
However I am confused with the following, because I’m using the massive Noctua NH-D15 CPU Cooler to cool my processor, it has two 140mm fans attached on top of the heatsink like this:
So I have a total of 4 fans (140mm) in my system, 1 intake in the front, 1 exhaust in the back, and 2 fans in between attached to my heatsink. What I’m wondering is, because I’m hoping to create the positive air pressure, does the 2 fans attached to my heatsink count as intake or exhaust?
I can’t find any definite info on this, I remember reading an article stating the CPU fans also affects the air pressure. So I’m hoping to ask you guys, do I need an extra intake or exhaust fan in my situation, to create this positive air pressure I’m hoping to achieve?
Thank you so much for reading and I appreciate your responses!
