@dude I believe I’m facing the same problem as @nfishr. Changing the line and rebuilding as suggested here ( did not resolve the issue, CPU load is still at 100% (although this hits only one core, with or without the changed source).

@nfishr It's very simple, there's only a single line of code that needs to be changed. Check the wiki if you don't know how to build packages manually.

@dude I was able to get rid of the log-warning by adding values to the thinkfan.conf, but the CPU-Load is still 100%. That issue from Github looks interesting, although I'm not sure how I would go about implementing it. Thanks though

@nfishr That Sensor warning looks somewhat suspicious to me. Sounds like it could be a config issue. I would also recommend taking a look at the issues on github, this one in particular:

@dude unfortunately nothing suspicious in the logs:

@nfishr I haven't had this issue. Can you post your configuration and recent journald log entries for thinkfan?

nfishr commented on 2019-02-18 22:31

just updated via this package to thinkfan 1.0.1 - VERY DANGEROUS: uses 100% CPU-Load when running. Could easily burn your CPU if not saved by BIOS!

dude commented on 2019-02-18 20:55

I've just adopted this and updated it to v1.0.1. Please let me know if you run into any issues. Thanks

We should update thinkfan.service from



ExecStart=/usr/bin/thinkfan -n

instead. This prevents thinkfan from starting as a deamon and allows us to debug it with journalctl -u thinkfan.
