Hello, After several months running OpenBSD 5.7 on my Thinkpad T410, this problem appeared a few days ago:
* when the systems starts, the fan is running at moderate speed, everything is fine. * after some 10/20 minutes, it speeds up to 4500 RPM and never slows down again. There is no CPU load, but it is possible that there is a short activity spike that triggers the fan acceleration. It does not happen on Windows, and when the fan is "stuck" at high-speed in OpenBSD, if I reboot into Windows 7, it will slow down after a while (a few minutes, perhaps) and behave normally after that (it speeds up when needed and return to moderate speed afterwards). "Normal" speed seems to be around 3600 or 3800 RPM (I saw once 1900 RPM) on OpenBSD, and "Fast" speed around 4500 RPM. On Windows, I saw 1900, 3600, 3800 and 4500 too. 3600 and 3800 are the most common. It oscillates between them depending on the load, moves to 4500 when there is alot of CPU activity and then goes down to 3800/3600 when this activity is over. 1900 does not seem to be achieved often; 3600/3800 are bearable, 4500 is not. When looking for information, I saw that this fan problem has already been reported, for example on this mailing-list in 2015: <https://marc.info/?l=openbsd-misc&m=142607724519024&w=2> I do not think I changed my system a few days ago, but can I check it? Is there a log of the /pkg_add/ I might have done? The other possiblity I see is that the OpenBSD driver may take into account a sensor that now returns bogus info (which would be ignored on Windows). Dunno. I always have this "PCH" temperature at 59°C, like the other poster. OK, now some info: =========================== $ uname -mrsv OpenBSD 5.7 GENERIC.MP#881 amd64 =========================== Taken immediately after boot (I just noticed the itherm0 temperatures were broken at that time...).
