Just today I started my new build for the first time.
Last time I check, the PSU fan didn't spin at all when computer was running.
I thpight that since there isn't any load to the system it didn't spin, or maybe it only spins on certain temps.

The PSU is Corsair 850AX gold.

Should the fan spin all the time?
Is there a way to fix this?
And is there a simple way to check if the fan is spining, like a software or somewhere in windows, so I won't have to mess with the case, lift it etc..

According to specs it's a variable speed fan. Leave the system run or do a SiSoftware Sandra test to see if the fan will come on. Touching the area around the power supply if it gets too hot without the fan running you might have a defective fan. Keep an eye on the other temps as well. Keep the case in a position where you can see whether the fan is running as you won't be able to tell otherwise.

I tThank you. I tried Batman AC benchmark for a long time and it didn't turn on.

Also my Asus 670 GTX DC2T is getting somewhat hot - near and over 70 C at that benchmark.
CPU temps are ok I think, below 50

If a fan is detected then a program will show speeds.

Do you know how much load is on the GPU- check with this- http://www.gputemp.com/
If it doesn't break 85c then its okay...

If there are vents on the PSU, can you feel some heat?

I am running this Sandra2012 overall bench.
It really messes up my system in terms of my windows is terribly luggy and freezes every action.
But all checks so far came positive.
even under 100 load each core according to Core TEMP - core 1 reaches 45 temp, others stay at 33-35

PSU FAN DOES NOT SPINS. Not at all. But it doesn't emit heat or anything. It is rather chilly.. but this is strange.
