Fans running loud - error code 4SNS/1/C0000008 TSOp —124
Hi,
My imac has the fans running at full speed and Apple diagnostics give me the error:
4SNS/1/C0000008 TSOp —124.
I have used the website below to try to decipher the code, but I haven’t been completely successful.

The codes on the link above, seem to apply to macbooks, not iMacs, since there is no upper-case “S” (only lower-case) and the lowercase “s” refers to the trackpad.
So, this is what I’ve decoded.
4SNS - Sensor, T - Temperature, S-? (capital S), O-Optical drive, p-?
What’s the “C“ in C0000008, is it just an hex address of some sort, or does it mean CPU?
I’ve bought the software TG-PRO, and it shows both optical and CPU fans at max speed and points problems with sensors, but cannot identify which ones.
Should I assume that I have to replace both sensors?
Thanks in advance.
Best regards,
Pedro
Is this a good question?
