Sep 21, 2022 · As everyone else said, add another 360 rad. 2x 360 rads will be enough to achieve reasonably lower temps and let the core boost for longer period. I have added an external radiator to my pc for 4080/4090 upgrade.

I use TWO 360mm radiators for a 5900X and 1080Ti, personally I wouldn't even consider running a 13900K and 4090 in a loop with only one 360mm radiator. It'll probably perform worse / be louder than just sticking with the stock cooler on the 4090 and a …

Nov 17, 2022 · I got a RTX 3090 which hits 400w and a 13700k under 2x 360 mm ek SE rads you hits about 60c and cpu around 70c with my ek harder fans at 1300 rpm. The 4090 draws around 450w in gaming from what I've seen excluding benchmarks and stress tests so it should be fine.

Oct 23, 2022 · My side mount is taken up by my Distro plate, so I can't install any rad there. I will be power limiting the 13900k to Eco mode (90-125W) and as well as the 4090 to 70% (315W). Will both rads...

Apr 8, 2023 · I am in the process of planning an RTX 4090 and 13900k build. I have an NZXT H9 Flow for my case and could run a max of 3 360mm radiators. In terms of thickness: Top: 30mm ideally, 45 mm would be pushing clearance for motherboard Side: 30mm, 45mm would be cramped Bottom: If I don't mount my GPU v...

Jan 19, 2023 · Hello, I would like to put RTX 4090 Gigabyte Windforce which is 331mm, and Artic Liquid Freezer ii 360mm rad inside Fractal Design North case. Is there enough space ? I would like to use 360mm, because my cpu is 13900k

Jun 25, 2024 · As for the rad - it depends if you want to exceed 600rpm or not. If you want to exceed - then HWlabs GTX, most balanced rad on the market. If you want to run below 600RPM, HWlabs SR2 is better and is not restrictive.

Aug 5, 2023 · Need some advise. I have slowly began a build in a 4000D airflow. My plan wa to get a 4090 and a EK Nucleus 360 rad for the front. Would this even fit or will I need to go with a top rad? Thanks

Nov 22, 2022 · I still want the head room for the 4090 to be able to hit its max boost as well. Both rads would be in a Fractal Meshify 2 case. So one rad in the front drawing air in, and the other 360 at the top exhausting air out. Thanks!

The general rule of thumb is at a minimum you need 120mm worth of rad space for every 100w of components. That said, I have a 7800X3D and a 4090 with (3) 44mm thick 360 rads and wouldn't want to have only 2 because of thermal overhead.
