GPU and System Cooling and Airflow Considerations

[dannymangman]

Hello friends,

I recently purchased a Cyberpowerpc that came with a liquid cooled 8700k, 32gb RAM, and a GTX1080ti (The MSI Armor OC Model). Im not overclocking anything and the 1080ti runs at a steady 1830MHz

Initially, the card was quickly reaching the 84C point within minutes. I installed a few additional case fans to bring my system to look like the graphic I have attached to this thread. Max Temperatures are now at around 80C with a 90% fan for the graphics card. The ambient room temp is around 23-24C.

All of my systems fans are on a curve based on system temperature and they all get up to just about max with the exception of the 2000RPM intake which i cap at 1700 or so due to noise.

The graphics card expels some hot air out of the back end of the computer, but some it comes out of the other side and hits the intake airflow.

Can someone offer any insight as to how my case fans are set up. Is the right-side GPU exhaust an issue that it turbulates with the intake airflow?
80C seems a little too hot for the GPU even though it is below the temp. limit and well below the 90C safety limit.

Thank you in advance to anyone that takes the time to offer any advice

Best Regards,
Dan

What case is it in? That front panel is heavily limiting your airflow (based on your drawing).
Also, you should be using identical fans at identical speeds on a push/pull setup, the way you have it now really isnt doing anything productive over a single fan.

It is a Phanteks P400 Eclipse Tower with Tempered Glass. The Push/Pull Fan set up is actually the one cooling aspect of the case I haven't changed. Not too worried about it since the CPU is pretty cool anyway.

It definitely is a bit limiting, but the bottom and top do have a decent opening so not quite as bad as my drawing insinuates.

Im not really seeing any "better" options in that case then, your layout is about the best you can do other than maybe different model fans.

The intakes are like $25 Noctuas and the exhausts are like 10 dollar thermaltakes.

Probably only be marginally better getting somewhat better fans. What if i perforate the front panel? Or maybe just put the PC in the fridge at this point lol

Well you are using static pressure fans, not airflow fans (I think based on the models). You dont really need more pressure.

I took off the front panel yesterday night and load temps dropped almost a good 8C.

I guess I can probably try a custom cut of the front panel.

Thanks for your help man.
