CPU fan is making loud cracking noise and nitrosense seems to have no control over cpu fan speed, however GPU fan is running smooth. My laptop gets super hot nowadays as only GPU fan is working well. How to get this CPU fan fixed at home preferably due to covid lockdown ? if someone knows the reason and solution please help.
Thanks.

    AshishJagdev, Hi, so recently i have opened the laptop, and then opened the cooling system, opened the fan disassembled it.
    I found that one of the fan was rubbing with the fan casing (as shown in photo , the metallic circle mark on casing was due to rubbing), It was because the casing was somewhat tilted, so i tilted it by force to other direction and made sure that fan lose contact with surface also i lubricate the fan using lubricating oil, cleaned it and its solved. No more rubbing and cracking noise from fan, its running smooth since then, no issue. 
    i think buying a new fan won't solve the problem as it was due to casing and not bcz of fan. you can also try that, just be careful with the delicate fan wire attached to the system, remove the battery first then proceed (i did without and there was sparking in circuit), remove all the wire connections. hope it solves the issue.

    egydiocoelho no brother its not under warranty now.
    Here is the link for the video     
    https://youtu.be/90raTbgXXxU
    every time i click on coolboost button on the nitrosense software the sound goes off for 1-2 min but then again same issue.
    the rpm control is also not responsive to the cpu fan as for max setting gpu fan speed is maxed out but cpu fan speed lags way below and cant reach to max rpm.
  • Is your laptop under warranty? Have you taken the laptop apart, to check if there is anything touching the fans?

    I have the same laptop with the same problem. It is very annoying.
    I haven't been able to find a solution either.

    I advise using an anti-static wristband and disconnecting the lithium battery.

    One of my buddies was having the same issue we took it apart and noticed color rubbing off the fan onto the fan casing due to friction. we tried the solution posted but it didn't help, we swaped the other fan onto the faulty fan case and it worked, the faulty fan wasn't having any issues in the other fan housing so it solved our issue.
