I have a laptop that I primarily use for Photoshop, After Effects, and gaming. I make sure to clean the fans regularly, but a few months back, I noticed that the CPU fan started making noise while it was running. I checked it out and didn’t see any obvious problems, and the fan looked clean as well. At first, I didn’t think much of the noise, but over time it became quite annoying, and the fan speed dropped to 4000 rpm. I thought about replacing it, but the service center informed me that I would need to replace the entire cooling system, which I decided against. Eventually, the fan stopped spinning altogether. That’s when I opted to buy new fans online and replace them myself. While waiting for the new ones to arrive, I noticed the old cpu fan was struggling to spin; they would get power for a moment and then lose it, and sometimes the CPU fan would start spinning without any issues. When the new fans arrived, I installed both the CPU and GPU fans, but I encountered the same problem. The GPU fan was working fine, but the CPU fan wouldn’t turn on. I checked it again and saw that it was trying to spin but just wouldn’t. Can anyone help me understand what might be causing this issue and how I can resolve it?
