The setup is only cpu, by this i mean the gpu is not in the enclosure but connected and drawing power. There is a large opening on the bottom, the psu draws the air in and vents it out. The only other fan is the cpu cooler. The airflow is in the path of the cpu cooler but unobstructed. The cpu has 95w TDP, stock settings, no overclocking of course. The intended psu would be a 50 celsius rated operating temperature psu, example: https://www.bequiet.com/en/powersupply/387 . This psu also has a larger fan and the airflow direction of the psu and cpu fans are the same. The psu is close to the cpu heatsink https://noctua.at/en/nh-l12s but not to close ,15mm. This would be almost a push\pull configuration while the pull part is also the vent. Also i attached here a scientific study performed on a 115 tdp pentium iv. https://www.researchgate.net/publication/257985684_Studies_of_Heat_Transfer_From_PC_Processor_to_the_Air_Cooled_Heat_Sink . From what i understand this study shows that the cpu only (ssd, motherboard, ram - but not the gpu) should not heat up the air temperature above 50 celsius (max 95w tdp).
Questions: 1.Does the PSU overheat? 2.How does the PSU react when power consumption is low but hot air is blown in from the cpu cooler?
If i am wrong please correct me.
