    Laptop's fan always remains on and the CPU usage is high and drops quickly after opening...


    I own an Acer laptop with Windows 10 and recently the cooling fan is always remaining on. The temperature of the CPU remains around 70 degC(higher than usual) at idle state. Whenever I open task manager, the usage suddenly drops from around 80% to 10%.


    I am suspecting that there is some shady process running which closes itself whenever I open up task manager and then continues when I close it.


    Could it be malware? I have already scanned my PC multiple times using Kaspersky Antivirus multiple times and didn't find any threat......please help.

    :)

    High CPU Usage (& fan noise) Drop Drastically on Opening Task Manager


    I suspect you still have a little critter that actually forces the CPU to go high unless Task manager is opened

    High CPU Usage (& fan noise) Drop Drastically on Opening Task Manager


    Thank you all for pitching in.

    After debugging my laptop with quite many anti-malwares, anti-spywares and a few anti-viruses, I downloaded a software to observe the CPU temperature. It turned out that the sudden drop in CPU usage right after opening the task manager is only because of the momentary spike in CPU usage for opening the task manager, no other reason.

    As for the sound of the fan, after debugging my computer, now its sound remains consistent even after opening the task manager. Even at CPU usage around 10%, it continues to stay loud, at least by my definition of "loud". For this reason, now I'm trying ​​to find a fanless model to buy.

    High CPU Usage (& fan noise) Drop Drastically on Opening Task Manager


    I am using Windows 10 in ASUS ZenBook UX305. The fan of my laptop runs quite loud in general but it drops down drastically every time I open the task manager. The sudden drop in CPU usage can be seen immediately after opening the task manager. I have run Malwarebytes and Eset online scan and quarantined the threats found. But the suspicious behaviour of CPU usage has not changed. Please help.
