I would have thought that your bios was set to go to sleep when you press the power button as well (I think S3 power sleeps but the fans run and S5 goes quiet with no fans), but if your sure thats not it, I would then look at your power connection to the motherboard. With the newer 20 + 4 pin setups of the new supplies (to accommodate both older and newer boards), its possible your 4 pin is not set properly. For most I have seen the 4 pin must be put on first so the 20 pin can hold it down, if you get it backwards the 4 pin can come loose. Its also possible you have a grounded mobo, if you put a screw where one is not meant to go (even if it lines up with a hole on the case) it can cause a direct short. A good rule of thumb is if the boards hole does not have a ring or star of solder on the top around the hole, then it is not meant to be used as a ground to the case and you should not put a screw or standoff there. And if your case has non-removable standoffs there (an actual metal bump from the case and the board doesn't have solder at that hole you would have to put some electrical tape there to prevent the short. Why engineers design boards with holes that line up but are not meant to have a screw is beyond me. I suppose their just stupid engineers. Stupid politicians, stupid doctors, stupid lawers, why not engineers too.
yeah i'd confirm in the BIOS and windows that you aren't putting it to sleep by accident.also blasting the dust with an air can might help.could also be a psu or a motherboard problem. i'd say the motherboard is more likely as it's telling the PSU to keep the fans on for some reason.
How are the fans connected? Are they to motherboard headers or directly off the PSU?

i think then the cheapest thing to do next is to take it to a computer repair shop explain the problem and suggest they test with a different PSU. ofc then they'll probably put a cheap PSU in there to replace the old one if that fixes it and charge you a premium for it.

The case fans are directly off the PSU, the cpu fan off the mobo.
