It seems unusual for this to occur now. The CPU doesn't typically fail like that in today's technology. A paste change would be helpful, but I'm not sure we ever really understood the exact cooling system. Is the cooler water-based or just an air one? What kind of fans are inside the case? How many? What type of case is it? I need to understand the airflow and how the CPU's heat gets released.
It seems the discussion only mentions the cooler without details. Could you clarify whether it’s an air cooler or a liquid cooler? That would help explain why the pump stopped working.
It's just an air cooler. The Be Quiet model isn't clear to me. The case setup is also confusing—I don’t know what they did. He bought it ready-made. For the fans, I really dislike how the installer arranged them; only one on the cooler and another as exhaust, no intake at all. That seemed like an issue right away. Apart from that, he’s only experiencing overheating during shipping, not while using it normally. Everything else stays cool and comfortable.
Honestly, if you decide to keep that case, add a few fans at the front intake to let in more cool air. Otherwise, I can inspect the fans, heatsinks, and other components for dust buildup. Dust can really slow down cooling performance. What kind of workload does the exporting application use? You could check Task Manager to see how each core is performing during that process. Is this a new project? Are these exports significantly different from what you’ve done before? Has anything changed recently—drivers, internet connection, PC positioning? Anything at all? Because a CPU reaching thermal limits usually happens only if the CPU is actually failing, not just because of heat. Something must be causing it.
May has likely addressed the matter further. In FLStudio there is an option for multithreaded mixer and generator processing. Turning it off reduces export temperature but increases playback load since it runs on a single core. Could a Windows program be trying to make use of multiple cores that conflicts with FL's own optimization?
Many motherboards, by default, enable unlimited turbo power settings for peak performance. However, this can generate excessive heat that a standard air cooler struggles to handle. To maintain quieter operation, adjust the BIOS settings and lower the PL1 and PL2 turbo limits. Reducing power usage decreases heat production but also limits speed. You can fine-tune these values in the BIOS to achieve an optimal balance. ThrottleStop is a popular tool that lets you modify PL1 and PL2 limits directly from Windows without restarting. Most reputable motherboards support similar BIOS configurations. The 9900K features a 95W TDP rating, so conservative limits help keep temperatures in check. Historically, Intel suggested aligning PL1 with the TDP and setting PL2 about 25% higher. For example: PL1 = 95W, PL2 = 120W.
Could you share an image of the PC you're referring to? This would assist in recognizing components and diagnosing any issues.
how much thermal paste did you apply?... if you remove the cooler again, is it spread evenly or missing in certain spots? Typically a pea-sized amount in the center works, though some prefer a small spatula to cover it uniformly. then secure the cooler with balanced pressure on all fasteners; my 9900k still runs around 75 when using all cores. additionally, I have a large water cooling loop. however, uneven pressure on the CPU can cause problems.
Here are some images of the PC. Apologies for the delay. I've been fairly active over the last couple of weeks.
