Client gave me an Imac 20" 2008 (I believe)

Fairly chuffed about it

anyway, the drive that was in it is a HDP725025GLA380 Mac FW 2008

Recovery was done on the drive (thats how i ended up with it)

I have replaced the drive with a small SSD and as a result the fans go mental. This is a known issue as there is a connection with the temp sensor and the Apple FW of the drive.

I have looked at all of the online fixes for this but im not getting anywhere,

This is a long shot but would it be reasonable to assume that if an identical 250 Hitachi was obtained and the FW was swapped over that this would sort the issue?

alternatively if anyone knows how to stop the fans from revving then pls let me know. Tried all the usual fan control software and its driving me up the wall

cheers

Andy

Some of the iMacs use a 3 terminal TO-92 sensor that's attached to the chassis of the drive. That's less of a challenge than the version that I gather the one you are talking about, which has an auxiliary connector that plugs directly into the hard drive.

In the latter case, I don't know if the associated FW is located in the EEROM or on the platters, or both.

If it's the ROM, you'll have to determined the location of the code and modify checksum, etc. If on the platters, you'll have to identify which modules are involved. No doubt that the FW version will be different from the stock hard drive, so you run the risk of bricking the drive by doing a partial transfer.

We see a lot of Macs and are interested to know, too. We haven't had time to experiment, but if we do, we'll let you know.

In the meantime, the only remedy that we know of consists of buying a replacement from Apple.
