cpu temperature

I have a Dell Inspiron 15 5510 Laptop and everytime I try a live USB with FreeBSD 13.1 or 14-CURRENT or after a bare metal installation I notice increased fan speed and overheating of my laptop. The cpu temperature rises to 55-65 Celcius at rest. The same thing happens in Arch linux. Only in...

There's a comment in the BUGS section of the OpenBSD cpu(4) man page: I'm wondering, whether * It's an Intel-specific bug, and both FreeBSD and OpenBSD have the same problem. OR * It's an OpenBSD specific problem, thus it doesn't apply to FreeBSD.

On a FreeBSD 12.1 install (powerd enabled and running), the CPU fan speed is at 100% even though top is indicating the system is 100% idle. If I do sysctl -a | grep cpu, I see the CPU frequency is the lowest (800MHz). As for the cx_usage, I see 100% 0% 0% on both cores. The CPU heat sink...

Hello, on a old Lenovo T520 I noticed that to set the CPU fan to .. sysctl dev.acpi_ibm.0.fan=0 sysctl dev.acpi_ibm.0.fan_level=7 .. results into an RPM of ca. 3300 where as the fan max is in the 5500+ area. In Windows with tpfancontrol the max rpm's can be set. I will test this issue with...

Hello everybody, Does anybody know how I can manipulate the fan rotation speed at my homeserver? Specs here. With FreeBSD installed the fan always rotates at maximum speed which is annoying due to the noise... Questions: 1. How can I monitor the fan regulation speed? 2. What is the FreeBSD...
