Windows 10: Fan still running even no reason

Hello,
I have All in One PC Acer Z3-710 with i5 on Win 10 (Anniversary). Unpacked a week ago so no dust inside etc.

Current temperatures all in normal
CPU 45-50°C
GPU 40°C
HDD 36°C
Also HW usage in normal
CPU 2-5%
HDD 0-10%
RAM 60%

Can anyone explain to me why chassis fan still running on 1100 RPM and not slowing down even for a minute?!? There is no reason to keep fan running when no activity in Win! Don't know how to fix it...already tried:
- flashing BIOS
- updating GPU (Intel+nVidia) drivers
- stopping "superfetch" service
- changing power consumption plan
- even booting in "Safe Mode" fan still running
- Acer bloatware is uninstalled

:)

 

Display drivers frezes during gameplay

Is there any plans for a Intel HD 3000 Windows 10 update? Intel aren't budging on the issue for some reason and I find it bizarre that the Windows 10 compatibility tool said that my system was fine for an upgrade only to find that in reality the graphics
card driver isn't supported by Windows 10. I think that this was one of the reasons why my CPU fan was spinning like crazy when I switched to Windows 10. I would never have upgraded if I knew that in reality the hardware was unsupported.

Its crazy that so many manufacturers are unsupporting Windows 10 with hardware that is still capable as it means that we can't switch up as we'll run into issues.

My CPU fan hasn't been the same since the switch to Windows 10. Even when I downgraded back, I'm running into issues with fan noise and hanging on shutdown.

 

Fan won't shut off after Windows 1709 Update

After doing the latest update 1709 (KB4088776), my CPU and disk usage exploded. I was able to lower that even though the CPU still runs high.

But, the really annoying thing is my fan is constantly running. My computer is cool as a cucumber and it still runs. It is idle and it still runs.

What can I do to get this fan to stop running? I tried troubleshooter and changing my bios settings, so don't say that. Something is causing this CPU to keep churning and this fan to keep running. My system was running perfectly before this forced update
ran. I have not added software for weeks. This update caused this.

What is the fix?

 

Don't see any problem with your fans running, from your temps they should be running, see the snip of my CPU/MB temps and fan speeds

 

Have info from Acer support that fan shouldn't be still running. Would be raising and falling according to performance. Think should be almost silent and passive if no reason. In my case 1130 RPM loud and disturbing.

 

With a CPU temperature of 45C to 50C I would expect the fan to be running. My CPU is at 36C and fan is at 2300+ rpm, I think fans will always be running as long as the computer is on. This protects the CPU from being overheated, as to fan noise, that's a different thing. I don't believe you're ever going to see fans not run at all when the computer is on.

 

Sure thing that fan won't stop at all but I believe around 800 RPM enough if no activity. Then silent. Not like now...

 

Fan speed is regulated thru BIOS, see if it allows you to change temperature/fan speed curve.

 

Flashed BIOS so checked all before. Only 1 option to control "Smart fan Enable/Disable". Nothing else. Of course tried both options. If enabled still 1120 RPM but when disabled over 4000! RPM constantly. Like vacuum cleaner. Crazy. Fan not slowing or speeding.

Tried. Not able to add Fan and control RPM. Unable to see my fan at all. Using HWinfo or BIOS for speed detection.
