How to easily control Fan Speed of all your PC fans (CPU, GPU. Previously I had the NZXT Kraken x52 installed and had the same issues, but I swapped it out thinking it might have been a fault with the cooler, but the issue still happens with my new air cooler. Manually change the CPU fan speed at 100 RPM on the laptop or PC to avoid overheating. I calibrated the fans in the BIOS with Q-fan control, set it to PWM and when idle it runs between 300-400 rpm but every so often it will shoot up to 1500-2000 with no apparent reason. For example, I left my PC on overnight, at around 6am, it revved up loud enough to wake me up, then stopped almost instantly. I've checked temps and CPU usage when this happens but nothing changes, the fan just seems to speed up for no reason. Every now and then, even when completely idle, the fan will rev up to full speed for literally 1 second and then slow down again. SpeedFan can even change the FSB on some hardware (but this should be considered a bonus feature). My CPU cooler is connected to the 4 pin CPU_FAN header, my chassis fans are connected to the CHA_FAN headersįor some reason my CPU fan is running rather eratically. SpeedFan is a program that monitors voltages, fan speeds and temperatures in computers with hardware monitor chips. To run the tool, open the FanControl.exe file. Unzip the package and store all the files in a folder.
I built a new gaming PC in July, specs are as follows: Step 1: Download Fan Control from the official Github release repository.
