Thanks pm-r. I think it was a WD drive that initially came with my iMac. Wonder if there is a series of WD drives that has the connector for the special temp sensor that Apple uses.
If there was, and I believe there were various brands Apple used, but each one as I understand, used their own style of connector, so not standard. And I don't think we can buy them via Apple or through an Apple Dealer.
So even if you still have the cable with the WD/Apple temp connector, no WD drive will be available to the general public.
You can use the temp sensor from the optical drive for the 3.5" HDD replacement to solve the temp sensor issue. Of course, you need to buy this sensor as the optical drive needs its own, too.

Wow. Finally made the upgrades and this 2007 iMac feels like a new machine! Added a 250 SSD and new 2TB WD HD. Created a Fusion drive and clean install of El Capitan. Still have to bump the RAM from 12 to 16 GB. I have one defective 4GB Corsair chip that Rember keeps finding errors in. Time to start migrating apps and data --I promised myself I'd get everything organized (remove duplicate files etc.)! We'll see how long this New Year's resolution lasts....

See, the machine is too fast for me now!
Late 2009 27" iMac running like a top!
I actually do have a 2007 and 2006 iMacs as well and wish I could spark some new life into them but you are correct, they suffer from the low ram limits... Still good for word processing though!

OK, but I thought from what you said in your post #33 above you were tweaking a 2007 iMac… "Finally made the upgrades and this 2007 iMac feels like a new machine!
We have our mid-late 2007 24" iMac and late 2007 MBPro 15" still running and still pretty fast for our limited use, and the MBPro works pretty well with a SSD installed, even though it only has a 1.5 Gb/s SATA bus. The conversion was done more for battery savings rather than speed, but still nice to have.
