Julo Petko, Strange, the patched driver works perfectly for me. I'm on kernel 4.13.8, maybe that has something to do with it.
Also, even with the patched driver you MUST set the tunables to GOOD in powertop, otherwise the CPU package won't get to C7. Another thing to check - did you do a cold boot after you installed the patched driver? E.g power off the laptop completely, and then power it back on? Apparently, this must be done according to the github page (If I understand it correctly) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1602888 Title: Dell Inspiron 7559 fans do not shut off once started, even when cool To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1602888/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
