PC fans tend to increase speed when under load rather than cooling down.
PC fans tend to increase speed when under load rather than cooling down.
Hi, I previously owned the 500FX case with four fans and later upgraded to a 7600X with 32GB RAM, a Vega graphics card, and an NZXT 750C cooling system. After installing these new components, my PC now runs at near full speed when launching applications—like Microsoft Paint, browsers, or Steam. The fans reach about 100% capacity, which is impressive, but it becomes annoying as the load increases. I’ve tried adjusting fan curves and even disabled FanControl, but it doesn’t work consistently. The fans still kick in during startup or heavy tasks, making the system noisy. It’s frustrating because I wanted a quiet build but ended up with a loud setup. Any suggestions would be greatly appreciated.
Did you verify if your fans use DC or PWM settings and adjust them properly in the BIOS?
Adjusted fans to PWM and voltage settings, but the issue persists with a different sound. I have five parameters to modify—CPU_FAN, CPU_OPT, SYS_FAN1, SYS_FAN2, and SYS_FAN3—but none resolved the problem.
The fans are connected via USB or power outlets. There is a label on the back indicating the power source. Please share photos of those labels and any connected devices.
I’m sure that’s what you intended. My setup included a hub, and the fans were already connected, though I didn’t interact with them. The second small compartment houses the AIO. I added an extra image to clearly show which cables correspond to the fans.
