Amiga 500 & 600 thermal footprint.

I have borrowed a Flir infrared camera so i made some pictures

So, does this mean we should have some kinds of cooling? Are those chips ok to run at those temperatures??

I often wondered if there should be some kind of cooling on a stock Amiga. Jeff, do you have any other Amigas?

These are really cool

Nice! Do you have them bigger?

49c should be OK for electronics. Heat is the enemy of longevity though so perhaps it's not a bad idea to put on a few small chip heatsinks

Without a fan or some other active cooling, how much does a small heat sink really help?

A fair bit I believe. Before the Pentium came along x86 CPU's only used a heatsink (no fan).

It increases the surface area of the hot object so yes it will make a difference. Active cooling will obviously make more difference.

I've got little heatsinks on my A500 chipset and it does keep the chips cooler to the touch. I can't qualify exactly how much the difference is. I will happily accept a thermal imaging camera should you wish to donate one for testing purposes

The die will be hotter than the surface temperature of the chip due to the plastic not being a particularly good thermal conductor. Interestingly, the shielding on the 128 doubled as a heat sink (visible 2 minutes into the video): [ Show youtube player ]
