I’ve been in the mood to modify my PC lately and I’ve been thinking about lowering temperatures in my full ATX air-cooled PC. I though about making 3D-printed air ducts, but I think that it’s a huge hassle and might not be that effective.

Here’s a list of the small things I plan to do:

- Seal off the edges of each fan to prevent recirculation and streamline the intake
- Seal off PCIE grills to prevent recirculation on GPU
- Have intake RPM be slightly higher than exhaust RPM (Using Arctic P12 PWM PST)

Will this be a good idea and do you guys have any suggestions? I really don’t mind noise. I even set my GPU fan curve to turn up to 50% at 50C and then ramp up to 100% at 75C. I’ll probably be setting my fans to run at around 1300 for exhaust and 1600 intake unless you guys have better suggestions since I haven’t tried it yet and I’m still waiting for my fans.

Also, I’d like to ask how my CPU fans will affect the exhaust rate. I plan to set a custom curve for the 2 Arctic P12s I’ll be putting on my Hyper212 and I’m worried I’ll end up with negative pressure. Considering the fans are inside and closer to the rear exhaust fan, I’m guessing it’ll help the exhaust fan more than it’ll help the front intakes.
