This part means literally nothing. 50C is scalding to the human body, so using touch to determine heat is literally worthless when it comes to PC parts since most parts run at higher temps. Same with the PSU. It's rated to run at 40C (for full wattage). 40C is pretty hot to the human body.

 

You most likely aren't pushing the unit to the point it needs to actually spin up the fan. It'll start using the fan to actively cool the PSU when the PSU needs it to. As you can see in this 2600 review (with a 1080Ti in the test setup), Cinebench doesn't really push the system wattage that much (only around 150w). Even in gaming it only pushes less than 400w altogether (1080Ti and 5700xt actually have similar power draw).

 

Basically, your PSU is fine.

Rx5700xt and a R5 2600, running Supposition benchmark on high or Cinnebench r20, nothing seems to get the PSU to start spinning its fans. Once I took off the side panel to touch the top of the PSU and it was pretty hot. On system boot the fan does one or two spins and then never spins again. Is the "zero fan" thing going too far with this one? Its only few months old.

It's fine. The PSU fan is temperature controlled. If it just never gets hot, it won't spin. Hot to the touch means absolutely nothing, and is a useless way to the temperature.
