Love my VU+ Uno4K se bought recently from w.o.s. but only one thing worries me. I know it has external power, a decent heatsink so no need it seems for a built in fan. However the processor temperature does worry me a little, it can hover around 65 to 70c. is this normal? I have been using a usb fan on top of the box keeping the temperature at around 54c, it looked ok on my old Duo2 but not on this much smaller box. Advice needed.
