Hey I just built my first pc. I put everything together and turned it on. The fans spin, the hdd light flashes, everything seems to be working. Then in about 5 seconds the PSU fan stops spinning. Everything stays on though. The PSU is a Corsair 650tx

I believe that model has a temperature controlled fan that varies its speed depending on the temp. It may, in fact, turn itself off if the temp is low.

Use a power supply tester because the fan should not stop spinning completely.

A PSU tester will just present the voltages that are present. It will not 'test' the fan.

In this discription of 'how to test the PSU', it mentions that the PSU's fan may not spin if the temperature or electricl load is insufficient. (Step 2) Your PSU is doing what it was designed to do.
