Re-applied thermal paste to heat sinks in late 2006 iMac
5 - 20 minutos
The ATI graphics chip on this model overheats and causes the computer to have lots of on screen glitches. I have read that keeping the temperature down is the key.
The guides were excellent! Made a job that I thought would be intimidating very straight forward. The only thing that I would do differently is buy some of the EMI tape to reapply later rather than try to save it. It is too finicky and tears easily.
Not sure how well this will work but worth doing just to see how it all goes together. I added more memory at the same time. I would probably add a bigger hard drive if I had the case open again. Now I just have to get the fans running a little faster and break in the thermal paste (I didn't know it needed a break in period) so I can see if I achieved my goal.
