Fans always at 4k

    So lately I've noticed my Macbook Pro to be quite noisy. According to iStat menus, the fans seems to always be running at 4,000 RPM, even if I am just staring at my desktop, with nothing open.

    They speed up normally when the CPU is under load, but they never go lower than 4k.

    I tried using SMCFancontrol to restore the default settings, but they still run fast. I even reset the SMC the other day hoping that would fix it, but it didn't.

    I've checked activity monitor and used a few terminal commands to check for any processes that are causing high cpu load or anything weird, but I haven't found anything.

    Any suggestions or ideas would be great!

    Run Apple diagnostic and see if any codes pop up. I had a similar problem with my fans and ended getting the top case replaced.
