.... you can't do it. Upgrade the drive I mean.

If you upgrade the supplied drive the fans go crazy. Looks like the temperature sensor has been built into the firmware of the drive - or rather the detection has.

Put a C300 in mine, performance was stonking, full SATA-III goodness. But the fans were at 4K+ constantly.

Bear this in mind.... I thought it was a shortcut to getting an SSD equipped i7 iMac, but I guess not.

To be fair the supplied 7200RPM drive ain't too shabby - but it's not an SSD.

My 2011 MBP i7 feels faster in general usage, but the iMac can handle far more multiple tasks.

For example I've got Win7, Win 2008R2 and Handbrake running right now, and you wouldn't notice.
 
This is bad news. In the not too distant future I may need a multi monitor desktop again to go with my MBP. I will be going for a Mac Pro now.
 
I looked at that, but I don't think it's applicable to the 2011 units. The trick of shorting out the sensors worked on the 2009/10 units - but they had a separate sensor?

I'm not going to be the first to try shorting anything on a 2k bit of kit, even I'm not that daft :D
 
It's far from absurd. It's a very clever and simple way of making sure that if you don't want any hassle, you will pay Apple extortionate prices to upgrade your HDD. I can see RAM becoming the next victim of the home upgrader with future iMacs.

It looks like the hard disk also has a propriety connector too:

Ifixit have posted more information on it.

It's a standard connector except pin 9 which apparently usually does the HD activity light in PCs is now where the data for the temp sensor comes from.

If you short pins 1 and 9 out it things the bay is empty and everything is good again.

Not an out and out catastrophe as you lot seem to think :p

Not so good though when the disk gets hot and the fan doesn't spin up.
