Log FormD T1 - first ITX build 5950x + RTX 3090 hybrid (CPU AIO - GPU Air).

Nice build but I would be a bit uncomfortable with those CPU load temps. You might have better luck with a custom loop or seeing if you can enable ECO mode on the 5950x. I have a 5900x / Noctua U12A in a NR200 that peaks around 73C on Auto OC for reference. 90C load is a bit toasty...

Agreed, I'm going the undervolt route (currently at -10 all core) @ stock clocks + adding some fans to see if that will tame the 5950x to more acceptable levels (specifically a 92mm slim to suck air from the side towards the mobo & an NF-A12X25 chromax under the rad as soon as Noctua releases it...). These 5950xs do run toasty, however they do throttle when hitting temp limits quite nicely as well. I've had no stability issues so far, but running benchmarks clearly shows the chip is temp constrained.

The next step from here would be a dual rad custom loop setup, but I'll cross that bridge a little later

Added a NF-A9X14 Chromax fan between the mobo and grill. It's a little loud so will probably need to do something about that, but 3DMark looks happier: https://www.3dmark.com/spy/18376348

Also added a simple grill on the NF-F12 to stop the AIO tubes getting in the way of the fan.
