Question M.2 NVMe Heatsink Touching GPU Plastic Shroud; Issue?

[theageless1]

Hi folks,

I recently installed a M.2 heatsink (Sabrent Rocket) for my Hynix P41 which was running +80 degrees hot during heavy workloads; the temps have now dropped by 30+ degrees.

However the heatsink is slightly touching the plastic shroud of the GPU (6700 XT). From what I saw there's no pressure, it's mostly like the GPU is slightly resting against it, quite minor however. How resistant is the plastic shroud to direct heat transfer? I just remember that plastic in general is a poor thermal conductor.

Especially during GPU heavy workloads where the fans kick in and create vibrations, potential issues?

Any input is appreciated, thank you!

It might be slightly touching the metal case, here are some photos:

Different types of plastic melt at temperatures varying between 180C and 360C so there's no danger from the M.2 heatsink which is probably under 60C. There are hotter components on the GPU PCB, e.g. RAM, which may reach 100C+.
