I too have this problem. Razer has made a bunch of bugs in their software and drivers, and for several months the speed control of their Razer Hanbo liquid cooling system has not worked on Synapse. Is Razer thus prematurely damaging users' equipment?

I reported this issue as a bug and I was told that they could not recreate the issue on their equipment and that I am on my own essentially. The Hanbo also works properly on Synapse 3 for some reason, but will not detect any temps at all with Synapse 4. And Synapse 3 has become very buggy where it will suddenly stop detecting my devices randomly. It is very strange. I also have a Razer PWM PC Fan Controller and it doesn’t tell me the fan speeds on Synapse 4. This is months later with no fix from Razer. I am considering swapping out all of the razer fans and the AIO at this point, as this issue apparently cannot be solved by Razer. I can’t tell you how many times I’ve uninstalled and reinstalled their software to no avail.
