With these 2 iMacs of mine it is nothing (no fan.) the power cord might as well not even be connected.

The cold is back with a vengeance to the U.S. East Coast. I am going to see if they boot under much colder ambient air tomorrow morning. They (and all of my old Macs) are in a partially finished upstairs that is quite drafty. The temp will be around 60F at boot up time. If they happen to boot in the cold then Merry Christmas to me. Otherwise it is definitely CAPS replacement time. I will probably go for those ESR CAPS since they seem ideally suited for power supply applications.

Are you still on your original 3.6V MB battery? If so, it might be time to open it up for a replacement. With the battery replace, it's also the ideal time to up the internal 256MB DIMM to a 1GB and max your Luxo baby out if you have not done so already. If you have never opened it before, have some compressed air standing by. You probably have enough dust accumulation for building your own dust hamster as I did. Also, watch for the very tightly sticking motherboard. If mine was like that then chances are that yours is too. The original Apple (foxcon?) paste apparently becomes evermore gluelike with age.

I will post back with my Christmas Day cold boot results tomorrow...
