I recently purchased a brand new Thinkpad T490 with i5-8265u (1.6 - 3.9 Ghz), 40GB ram + 1TB NVME however the fan noise is driving me bonkers.
Using the ‘sensor’ app I can see fan at 0rpm with no input for a few mins but as soon as I open a random browser tab and refresh it ramps up to 3500rpm and stays there for about a minute if no further input. If I’m just casually browsing it sticks at 3500-4100rpm.
xentop looks how I would expect. I have 8 AppVM’s and 8 sys-VM’s running. 90% of VM’s are idling at any point in time. But I have also tested with no AppVM’s running after a restart and can reproduce the same fan noise with just some basic activity in dom0 e.g. Using Qube manager. I even notice the fans ramping up when accessing the GUI version of the UEFI setup utility (f1 on startup).
Laptop bios =
enabled but also tested with
Ambient temperature = 20c (68f).
I have an LG 4k external monitor attached but tested without monitor, same results.
I have also tried:
sudo xenpm set-scaling-maxfreq 0 1600 sudo xenpm set-scaling-maxfreq 2 1600 sudo xenpm disable-turbo-mode 0 sudo xenpm disable-turbo-mode 2
But I don’t notice any difference. I imagine many qubes users using machines with less resources so I just want to understand if this is normal/expected behavior and whether there is anything else I can do about it. Or do I need to purchase a desktop for silence?
