laptop fan noise
Friday, January 3rd, 2020 02:11 amI have wasted several hours today trying to figure out why the new laptop I bought my mom has its fan running most of the time, even when CPU usage is very low. My own laptop usually does not have any noticeable fan noise until CPU usage goes up beyond what is used for normal web browsing.
Both are HP's; both have only SSD hard drives.
Mine is Windows 8.1; the new one is Windows 10.
The new one has twice as much RAM as mine.
The new one has twice as much SSD drive space as mine.
CoreTemp shows similar temperatures for both laptops.
Both SpeedFan and HWMonitor fail to find any fans in either laptop, so I can't compare fan speeds.
The BIOS in the new laptop has an option "Fan Always On", but disabling it made no difference.
Lowering the "Maximum Processor Speed" in the power plan settings made no difference.
When I put the laptop to sleep, the fan turns off. When I wake the laptop, sometimes the fan stays off for a while, sometimes it comes back on fairly quickly*.
I doubt the noise will bother my mom much. But it bothers me to think that if I ever buy myself a new laptop in the far future, there's no way to know if I might end up with this same problem. I thought one of the benefits of SSD drives is that they run cool and quiet.
I am curious now if the laptop I ordered my niece (a different brand with different specs but also Win10) will have this problem too or not.
*If the noise ends up being from the laptop doing some kind of temporary automatic scanning or updates in the background, I'll kick myself for having wasted so much time researching the (non)-issue. But I'd also like to kick Windows for making it so that such processing is never accurately reflected in the Task Manager's CPU usage.
