Lol spring loaded center punch, like 4%.
Thats soon many fans lol. My case is a full tower, I run 3 intake up front, 3 exhaust up for the aio, 1 exhaust on the back, one intake on the bottom, and then power supply us also setup for intake at the bottom power supply blows directly across the gpu pushing the hot air up and back to the exhausts. I never head a peep out of my power, and it's at ear level on my desk.
