Dell Optiplex 980 SFF Overheating
I just recently noticed that my DELL Optiplex 980 SFF is overheating. It has a Intel core i3 CPU 540 with Windows 10 pro and 12 GB ram and a 256GB Samsung SSD 840evo and a 1tb HDD. I removed my GPU and my HDD and cleaned the whole PC and PSU but still it is overheating in the PSU area. Even though the area is well ventilated it still overheats. I just use Microsoft Teams And YouTube in that PC. Please help me Dell Community

Probably an old/failing fan.
Or, the thermal paste on the heatsink has dried-up and your CPU needs to be re-pasted.

Will the thermal paste issue cause my PSU to overheat because no other component other that the PSU Overheats

Absolutely. Thermal paste eventually dries up after some years. Probably once every 5 years is good for replacement. Sooner if CPU regularly runs hot (gaming?) or there's overheating issues.
Thermal paste can be a little expensive for a little tube. But I suggest around $8-$10 tube and not $2.
You can see YouTube videos on application if you want. I apply it as 5 dots like the 5 on a dice. I don't trust just 1 larger dot in the middle to reach all the edges. And remember, no overflow.
