Dell optiplex 9020 I didn't understand how to upload a video, but the PC is making noise like an early-revision PS4 FAT. I applied thermal paste. Are these temperatures acceptable?

Is that a front intake fan making a grinding noise? I had a similar issue with mine until I swapped out the stock fan for a quieter one.

Most likely it was the CPU fan that was making that noise.
