Worried about PSU fan

Hi, my psu fan randomly stops and starts again right after, it is supposed to be a feature according to the brand. but it didn´t do it before
 
Have you tried opening and cleaning the PSU? The same with the CPU and GPU. Temps can affect power draw and efficiency.

The PSU fan stopping shouldn't be an issue as long as it spins up again when temps demand it to. During winter the room temp generally goes down so the fan will spin up less frequently.
