The processor temperature remains unchanged regardless of reduced fan speed.
Hello, I see you're trying to understand why your CPU temperatures weren't dropping as expected during benchmarking. It sounds like the fan speeds were adjusted in BIOS, which likely helped reduce heat buildup. The results you shared suggest that even at 75% fan speed, temperatures remained relatively high compared to what you'd expect. Make sure your cooler is properly seated and clean, and consider checking for any dust accumulation.
Don't have to repeatedly enter BIOS to adjust fan curves... This GitHub release handles it. You can set a fixed curve at 84°C, so around 78°C the fan won't run at full speed—likely around 90%. The curve guides the fan speed changes based on temperature; it smoothly increases speed as needed. If the fan isn't responding to temperature changes, the issue might be with the tower's components like heat fins or spreaders.
The speed at which a fan operates affects cooling performance, though running it at full capacity isn't always necessary. Reducing fan speed can lead to increased heat buildup, but this isn't the only factor. As noted by @Dukesilver27, you don’t always need BIOS support for fan adjustments. The 77C processor may handle high loads well and cool down quickly afterward. First, assess your hardware’s heat generation and choose a case that fits. The cooler type, size, and orientation matter too. Your system’s overall thermal demand depends on CPU, GPU, and other parts. Ideally, you want a balanced setup with front intake fans, rear exhausts, and possibly an aftermarket controller. Providing detailed specs would help tailor the solution. Key elements include case design, fan placement, and expected heat output. Cooling demands change based on components, but generally aim for two to three fans drawing air in at the front, two pushing it out at the top, and one exhausting at the back for effective airflow. A common error is using solid-front cases that restrict airflow, which can hinder cooling. Liquid cooling isn’t necessary for most consumer setups. Putting an AIO into a tight front case with side vents is often counterproductive. For example, a Fractal Pop XL Air paired with a tower cooler on a 12-core/24-thread 5900X running PBO with an RTX3060ti-OC can stay under 70-72°C, while fans only reach 60-70% until the CPU hits its 90°C limit (or 88°C setpoint).

Hi there, thanks for the kind words. I've been working on this for several hours now, so I think it's time to pause and keep going tomorrow. Appreciate all the feedback! Take care!
