I just noticed that all 3 of my fans on my PC are not running.

There are 2 on the side and 1 on the back, at first I thought there were 2 on the back, 1 towards the top and one in the middle, but it turns out the one at the top isn't a fan, it's just blowing lots of hot air out of it. (atleast I don't think it's a fan)
I've taken some pictures (one with an arrow pointing at the only area where hot air is being blown) aswell as a screenshot of my specs, any advice or help would be greatly appreciated :)

I should also add that I recently cleaned out my PC for the first time in a LONG time, so I possibly may have knocked something I shouldn't have but I doubt it and I should also add that here in australia it is currently 40degrees during the day and 30degrees during the night.

Since those are LED fans and the lights are on, I would assume the blades should be turning. Desktop fans generally always run unless set specifically not to in the bios, it is possible it just isn't hot enough for the fans to run, if the motherboard is controlling them.

 

You may have bumped a 12v connector slightly lose while you were dusting the computer out, those LED's might run on the 5v line.

 

The power supply should have a fan (which likely explains why you feel warm air coming out where you mention), generally it is not something you see as it pulls air from the bottom (inside the case) and blows out the rear. I would try to get those fans turning as it will help keep the total case temp down.

Now that I think about it, there is a fan coming from the power supply but its on the inside of the machine, putting downwards.

That is the only fan that is running though, the one in the middle at the back is not and I do not know why :(

Sounds good! Fans do wear out, often if the machine has been running for years without stopping, when the fan stops, it just never starts back up. happy computing!
