Suspend mode and damn fans

All my life, including suspendmode on my computer, I became aware that the computer was getting quieter, but 1 fan is not being cut down, and I thought that this is how it should be.

But then a programmer came to visit me alone, and we touched on this topic. He was surprised that not all of my fans are turned off in the slipmode, and he said that probably because of the old motherboard or something else.

I was so sad! After all, some may not turn off the computer, put a sleep mode and sleep in the same room at night, without listening to zhzhzhzhzhzhzhzhzhzh

Yesterday I went into the BIOS, look for something on this topic. I went to Power, and there something like “turn off video on suspend” or something like that - it was disabled! switched ... and here it is.

In sleep mode, no sound, and wakes up a second for 2. Lepot ...

I hope there were the same lapuha like me to whom it was useful to know.
P.S. Yes, I confuse suspend, standby and sleep mode.
