  • Hi ist there any possibility to test if the USB4 Port are fully capable of using the TB3 protocol needed for eGPU’s?

  • Hi, I just tested usb4 port is working with Razer core x egpu enclosure, and nvidia drivers installed successfully.

  • Hi. Having seen a YouTube review of the PN64, where they mentioned the high fan noise level, is it the same with the PN53? Thanks in advance.

  • Perfect thanks for the answer, because I ordered a 6900HX here aund my main GFX card is in an Razer eGPU enclosure.

    Hopefully I get my system soon

  • Oh, thanks. Probably the thermal management is different from that of the Intel PN (in the YouTube video it is very noisy, one of the noisiest, compared to e.g. a Minisforum UM690…).
