Windows: why does the cooler start making noise in display sleep mode?

Question

Windows

On a laptop with Windows XP, as well as on a desktop with Windows 7, I have been observing the following picture for a long time: some time after Windows goes into sleep mode, the processor fan starts to make a frantic noise.
It would seem that the problem could be in a specific computer, but this happens the same way both on a laptop with XP and on a home computer with seven.
What could it be?

Answer 1

Hmm... And on your system for an hour, does anyone count bitcoins in idle? Are you sure that the system is clean from viruses and trojans?

Answer 2

1. carefully and thoughtfully check the bios and operating system power settings. My laptop stopped making noise with the cooler when I messed around there.
2. check if all recommended and additional updates are installed on the OS and all other software,
if the latest versions of bios and drivers are installed.
3. check your antivirus settings, do a full system scan and defrag after clearing browser caches and temporary files, and check the machine with live-cd cureit, for example.

Answer 3

Try disabling wake timers in the OS: Control Panel\Hardware and Sound\Power Options\Change plan settings - Change advanced power settings - Sleep - Allow wake timers set to Disable.

Answer 4

For the sake of checking, you can also leave the running task manager on the performance tab - you will see if there was an increased load on the processor. My microsoft anti-virus program sometimes does something in the background.

Answer 5

Maybe it's just hot and the iron, relying on the indicators of the sensors, accelerates the airflow? In such a case, Windows is irrelevant to the question.

Answer 6

Are you sure it's the cpu noise? Most likely your hard drive is disabled. Or the green functions are incorrectly configured. Go to power options and check everything there.
