Did I use the correct thermal adhesive tape?
I just replaced the HDD from my iMac 20" late 2006, because the old one was broken. I installed Snow Leopard and everything seems working fine! I used this guide to do the job: iMac Intel 20" EMC 2105 and 2118 Hard Drive Replacement
At step 23 I was not able to keep the adhesive tape for the thermal sensor and ordered a new one ( http://www.amazon.com/Akasa-ak-tt12-80-T... (in my store it was much cheaper) ). I'm unsure if this adhesive tape is the right one for this. It has compared to liquid thermal adhesive a much lower thermal conductivity. The tape has a thermal conductivity of 0.9W/mK and a liquid thermal adhesive of 9.0W/mK.
I choosed the tape, because it was much cheaper, it is easier to handle and to remove and it seemed that it was originally used by Apple, too.
Do you think, that the thermal sensor measures a too low temperature as the thermal conductivity is that low? It would be bad as the fans wouldn't speed up when needed.
I don't know the "normal" temperatures for a HDD. As I'm writing this (and doing nothing else) the HDD has temperature of 37°C (98.6 F). Does that make sense?
Thank you very much for reading!
That's what I tried to say, yes.
Okay so here are the temperatures. Unfortunately Temperature Gauge Pro doesn't support Snow Leopard. So I looked for another program and found Temperature Monitor from Bresink (couldn't add a link, because it was flagged as spam)
I started the computer and did stuff like streaming HD videos and copying large files to the HDD, so I think the computer won't get any hotter. After that it cooled down a little bit but not completely. I didn't know how to change the language (from german) to english of the program so I will just try to translate it:
purple: surrounding air (I think it's just the air in the computer)
green: CPU temperature diode
white: CPU area
turquoise: graphics processor temperature diode
orange: HDD bracket (I think this is the sensor I reattached)
pink: optical drive
There are two sensors for the HDD. The first (red) one shows the capacity of the new disc in its name , so I think the sensor is from the HDD itself. Further I can know that the sensor is still attached to the HDD as long as the orange and the red temperature is similar. Otherwise the orange temperature will drop as you said.
I hope I translated everything correct and the rest of my text is understandable. If not just tell me and I will try to find other words!
