Why does my computer sound like it’s revving up?
That’s definately fan noise, but it could be coming from either the cpu fan or from the gpu fan. Take the side cover off and narrow down the area of the sound. Also, download and install hardware monitor (freebie) – check the temps of your cpu and gpu.
Why do my PC fans keep speeding up and slowing down?
Check the heat sink also on the CPU. If dust has accumulated in the heat sink finials then blow it out with a can of clean air. Try running the machine with the cover off to see if the extra air flow cures the problem. Your PC may be overheating causing the fan(s) to speed up to cool thing down.
Why is my computer fan speeding up?
The most common cause why a CPU fan would run at full speed is that its sensor is not working properly. The solution here is to replace the fan itself. But you need to see that the processor is not always hot. You can use third-party applications for this purpose.
