How to disable HD temperature sensor Mac Mini 2009

I just broke off the temperature sensor cable of the HD SATA board when putting in an SSD. It really looked like a spudgeable thingy, yet it wasn’t.

The sensor should be no longer relevant, but the system now thinks it is a Nuclear Power Plant core and turns the fans to a zillion RPM.

So my question is: how to fool OSX to think this sensor IS NOT THERE in the first place, and taken out of the equition to calculate the fan speed. No problem to Hex Edit some kext files.

Options I consider no solution are:

Installing MacFanControl. I did that, it helps a tiny bit, but only from 10 seconds after boot.

Connecting the 2 pins on the SATA board with some conducting material. It does not work.
