The only difference is that the broken one is online and self update.

So same hardware, same OS, same settings. Both stops the CPU fan if I try to set it to anything. Replacing the boot drive again to the online (hence updated) one and neither v111 or v112 works. I took my computer offline, replaced the boot drive and then both v111 and v112 can suddenly control the CPU fan again where changing curve/controller settings adjusts the fan as expected. I cloned my boot drive a month ago and the clone haven't been online since. FanControl doesn't view this as errors, nor does it give any indication to what might be wrong. This would indicate that I somehow corrupted a setting, but I disabled starting at startup, rebooted and started with a fresh v111 and it still didn't work. Downgrading to v111 didn't fix the problem, nor did rebooting. GPU fan control seems fine though.Īuto pairing obviously doesn't work, but auto pairing and threshold setup worked earlier this week (v111). I have opened the computer and verified that the CPU fan does indeed stop.Ĭase fan control is dead in another way. Occationally it spikes for a single reading before stopping, like going 800-1100-0 RPM when it was supposed to drop to like 500 RPM. I even tried a flat curve at 50% and this went to 0 rpm even when the system set it at 47-52%. When enabling it jumps to 0 rpm within 1-2 updates regardless of selected curve. When the CPU fan is disabled, the system takes over and it reports RPM as expected. It asked if I wanted to upgrade to v112 and I clicked ok, it restarted and now the fan controllers can't be controlled. I had a setup with v111, which worked as expected.
