Question PMS-PD heating too much?

[SartoZ]

I recently notice that the USB port (and the nearby area) of the PMS-PD rev3 in my Ashida becomes quite hot after ~30 min of gameplay, I mesured 45/46°C. Besides that it seems to work fine.
Is it supposed to be normal or the PD is going to be fried soon?

SD to USB interfaces do get a little bit warm during use, and the PD doesn't have a heatsink. 45°C sounds about right for passive radiance

Thanks Stitches kind as always

If you want to improve the temps for peace of mind, you could get a bag of those little 8x8mm arduino heatsinks with the sticky backing and plop one on the warm boi
