This is my collection of heatsinks and fans that I have grabbed from old VGA cards, motherboards and power supplies.
In today’s market for PC cooling more is always better, which can make it difficult fitting modern oversize heatsinks to vintage hardware with limited space for cooling. Finding these small heatsinks in shops can be difficult if you are not willing to order from specialists on the net focusing on overclocking and modding such as Performance PCs which offers heatsinks from the tiniest to the extreme (they also got a 120x58mm Delta fan which draws around 30 watt).
Older motherboards usually have a low stack height heatsink on some of the chips and older graphics cards from the GeForce 2 era have heatsinks that will most probably fit your Amiga project. I have even found small heat sinks in a switch once (the two tiny silver heat sinks in the middle of the image) which would be ideal for cutting up and apply to tiny chips.
I can also recommend the VGA memory heatsinks by Zalman, they are the blue ones on the right. The eight small blue parts on the left are super tiny Zalman heatsinks that come with their VNF-100 VGA cooler. Those heatsinks are just a couple of millimeters tall and are going to be mounted on the chips under the 72-pin SIMM slot in my CyberStormPPC.
There is also an actual Motorola 68040 heatsink to the left of the green one and the fan at the top right is an actual silly five mm and five volt fan from an CyberStormPPC.
