H700i Bad Airflow.

[smgxr]

My H700i case is restricting my airflow so bad that I have to keep the front and top panel off. When they are on, I get 89c under load for my cpu, and 82c under load for my gpu. When the panals are off, I get 66 for the CPU, and 43 for the gpu. Before my CPU was at stock and now its oc'd to 4900mhz and runs fine without the panels.

Idk what to do except mod the panels myself to improve the temperatures. I cant leave them off because I have 5 dogs and 4 cats in my house, and I dont really need to explain why that matters.

Any ideas?

Well, what else you'd expect from a case that has solid front and top panels? While solid panels may look clean and neat, they wreck havoc on PC's airflow.

Since the airflow restrictions are so great for stock fans to handle and without modding the case itself, you're left with only by going with high-end static pressure fans. So, that the fans have the power to pull air in and push air it out through the small openings located at the panels sides.
E.g Noctua NF-A14 industrialPPC-3000 PWM with a static pressure of 10.52 mmH2O,

For comparison, the stock fan, Aer F140 has static pressure of only 1.42 mmH2O,

2nd option would be going with a PC case that doesn't have solid front and top panels, e.g Corsair 450D,

And to protect your PC's internals from animal hair, you can also use Demciflex filter kit with 450D,

I'm using Demciflex dust filter kits with my Corsair 760T v2 case (Skylake build) and Corsair 750D AF Edition case (Haswell build) and so far, i'm very pleased with the performance of Demciflex dust filters. (Full PC specs with pics in my sig.)
