S5 temperature sensor disabled?

[greyday]

Apologies if the answer is out there somewhere, I've spent several hours reading threads here and googling to no avail; I bought a used S5 from aliexpress and it works great, but since I replaced the fan with a pair of much quieter ones, I want to be able to monitor the temps. However, the temp reading is constantly 0. The machine hashes fine, and it is not running insanely hot as far as I can tell, just warm or slightly hot to the touch, but I want to play with the frequencies and clock speed (part of why I bought it, a tester to see if I want to buy more), so I'd really like to re-enable it. I have been messaging with the seller, who is very nice but I think the language barrier is causing a problem, the responses are polite but tend to be more reassuring that it is working fine so I don't think what I'm asking is translating well.

Anyone have any ideas? I flashed the firmware to the Nicehash one (since I'll mostly be using it there) and it didn't seem to change anything so I think it must be a hardware hack. Any answers or information would help. I plan to take it apart this weekend and delve into figuring it out...

The temps sensors are chip level, there is nothing you can do that will revive it,  so I wouldnt bother taking it apart and risking damage for nothing.

Hmm. I guess I'll just cross my fingers and hope my fan replacements don't burn it out...
