Those same educated engineers (and not our groceries salesman) thought that when its not really needed the fan can stop. So the "specifically" in your sentence is simple your opinion and not the reality.Power supplies are engineered specifically to be used with a fan by formally educated electrical, computer, and thermal engineers, designers, manufacturers, and software developers.
10hours of typical and some idle operation at 25C room temp. Do I need to start the fan? Is the PSU going to burn at 45C or even wear out?
Is the 15W avg (Input minus output power) or even the peak 20W heat going to heat up the rest of the system?
Same time and same environment for the GPU.
I guess 40-45C is too much... for something that that has a Tjmax close to 100C
FYI the same GPU under the same operating and environment conditions dumps the same amount of heat into the case with its fan spinning or with it stopped.
