How to make Antminer Z15 work with immersion cooling?

[Mr.Claw]

Hi, i'm new to mining, we have bought 2 Inno A10 Pro miners and 2 Antminer z15's to try out mining. A10's were prepared for immersion oil cooling with fixed fan speed, but Z15's arent. Is there are way to make them work with it? Firmware controls for it are very limited, section that had custom fan speed doesnt appear in the configuration and there are no advanced options available, SSH controls seem to be completely disabled.
All they do is just start up, run the fans at quite high rpm for a sec bubbling the oil and then stop with a failure light, probably because it cannot reach required speed on that fan.

There are fan speed sppofers you can plug into the fan cords to trick the control modules into thinking the fans are running fine. This enables you to eliminate fans entirely and cool your Z15 any way you like.

I'd first look at alternative firmware for these ASICs. They might have a fan speed controller or fan shutoff feature, but these firmwares are paid.
If such solutions don't exist, then you'll need to look for a sensor that can fool the fan speed controller.

A quick search didn't find any simple solutions, as the Antminer Z15 isn't the most popular ASIC for mining in our country. There are generally many ready-made solutions for Bitcoin ASICs.
