    Hello,
    Just by starting Windows 11 in Parallels Desktop 19.2.1 (I'm not running anything there besides Windows itself), makes my macbook fan runs like crazy.
    If I shutdown Windows and close Parallels they soon get back to silent.

    Before Parallels 19 I never noticed such high speed fan. If I let my Windows on, it keeps the fan at 100% the whole day. This is super annoying.

    Anyone facing this and tips to troubleshoot it?

    Thank you.

    My specs:
    =================================
    Macbook Pro, 15-inch 2019
    Intel Core i7, 2,6 Ghz
    Radeon Pro 555X-4Gb / Intel UHD 630 - 1536Mb
    16Gb 2400 MHz DDR4
    Sonoma 14.3.1

    Parallels VM configuration:
    CPU&Memory : Automatic (6 CPUs, 8Gb RAM and up to 4Gb for graphics)
    Graphics: Scaled + Always use High Performance Graphics
    Windows 11 Pro N (latest updates)

    Issue continue after 19.3.0 update and after installing MacOS Sonoma 14.4.
    Anyone experiencing this issue?

    Hello,
    Same issue for me as well: Macbook Pro Intel with Ventura and Windows 10 VM. Parallels version 19.3.0. In addition: Windows black screen when not used for a while + Windows screen autoscale... it's going worse and worse... Experience is becoming unacceptable.
