Testing on a new setup with an Intel 12900k and various components. The cooling setup includes a Lian Li Galahad 360, Z690, ROG 3090OC, 6600MHZ DDR5 RAM, and nine case fans. I’m checking if pressure from the fans is excessive or if temperatures are unusually high. During a single Cinebench run, CPU temps reached 96°C on one core, rising to over 100°C with longer runs. Prime95 caused a blue screen. I’m unsure what’s causing these issues and would appreciate any guidance!

It looks like a solid 12900k is achievable. These high-performance chips really demand careful voltage and bios adjustments to unlock their full potential. For cooling, consider placing fans on the sides and bottom for intake air, with the top as exhaust. Prime95 isn’t really useful here—it usually shows much higher temperatures than you’ll actually experience. Just a note: your 12900k lets you run RAM at 6600 MHz, which is impressive compared to many 12th-gen models that struggled around 6000 MHz before IMC instability problems emerged.

Based on ASUS's website, these components should work at 6600 MHz. They seem quite sensitive at that speed—stock performance is likely better than XMP settings. Your PC didn’t handle the XMP profile well, so stick with default speeds unless you have another suggestion.

It seems there’s a lot of air entering the case with very little escaping, which is the main problem. You also lack rear exhaust, and it looks like you’re using side intakes instead of front ones—this makes things a bit unclear. (I’m not even sure what you mean by “no ideal setup”). In short, you need to consider air cooling as if you’re working in a wind tunnel, with fast airflow in and out.

currently the setup has the AIO handling fresh air intake while the remaining units manage exhaust. I changed this mainly because when fans were reversed—bottom, back inlet, top exhaust—the bottom fans produced a louder sound, likely from the filter.

Motherboard makers often highlight their memory speed potential, mainly for marketing purposes. Boards with eight layers and 4 DIMMs featuring Alder Lake CPUs can reach speeds around 6200 MHz, but achieving higher frequencies usually requires significant tweaking and isn't easy without substantial work.
