I already read about some guys who already did it and had no problems. Getting the temp sensor from an older iMac would be an idea to solve the problem. So you may want to rethink your decision not to take it to either an Apple Store or AASP in your area. Meaning if you break it, you're paying to fix it, and that will NOT be cheap. Make sure it's magnetized, and even then the magnets holding the glass panel on will have a habit of grabbing the screws and your screwdriver.Īlso keep in mind that by doing this, you will be voiding any warranty you may still have on that system. You'll also need a T-10 Torx screwdriver to get the display panel off. And that glass on the front is not tempered, so it will break into very sharp little shards if you should drop it. I'd say it's at least worth a try, and you can probably find that cable on ebay or something.Īnd have you ever taken apart an iMac before? I won't say it's hard, but it does require some not so common tools to do it properly, and there are some potential safety hazards to be aware of, like two exposed power supplies once you get the display off. I can't guarantee it would work, but if you could get your hands on one of the old sensors from systems pre-2009, you could always see if that would work as a substitute. I have not seen any other drives, except those sent to me by Apple (I'm an ACMT) with those extra pins for the temp sensor, and a cursory look over the drive looks like there's a little extra PCB compared to other drives.

And while you could always choose not to connect this particular cable, it will cause your HDD fan to default into running at full speed all the time.
I can't give you all the details, but I can say that around the time of the 2009 models, Apple switched from using a sensor that was basically just glued or taped onto the drive to one being built into the drive. PS: I already did a lot of these things, please don´t tell me to go to a apple dealer. Is the Temp Sensor a Diode or a resisitor, or even the RS232 some guys believe (i don´t)? Do only OEM HDs have the right connectors or firmware? not a good idea in the tight-fitted iMac enclosure.ĭid anyone do it? or can give me a hint? Which Pins are used? - Maybe someone put his 1TB WD Model and knows. instead of ±4000īut the WD drive is a very quick 7200Upm drive and it surely will get hot during use. I know about the option to shunt out the connector, so that the fan will only have 1000upm. On the WD Descriptions it says, that 6 of the Pins are used (eg switching to SATA1-compatibility, but none for temp. My Problem is: The drive i bought has got an 8 Pin Connector instead of the 6 Pin Connector showed. on the picture above there are even the numbers to get it from an apple dealer. so it shouldnt be a real problem to solder it on the new drive or put a new Connector on the cables. 1109/cables1.jpg you can see the different Connectors, but there´re always the same 2 Pins used.
it´s not an external one anymore, but there´s a 2-Pin cable connecting directly to the hard drive (they say, i didnt open the iMac yet). Actually the WD drive is already lying here on my desk.

I plan to upgrade my HD from the built in 1TB Seagate ST31000528ASQ to the 2TB Western Digital WD2001FASS.
