A few weeks ago while browsing the ebay vintage computing category I found a kit or a system where the CPU (soldered 386 or 486 in PQFP format) was pictured with a cooler on it (something designed for PQFP, not something improvised).

Now I'm trying to google a photo of such device for a bit more thorough studying, but either I'm not good at defining the object, or they are indeed hard to find...

Can you help me with this? I too have such a kit at home, and when its time will come to become a system I don't want to resort to superglue 😀.

Thanks.

They're just tiny heatsinks that would probably fit something like a 386SX. I seriously doubt you're going to find anything with a fan for a chip that small. PQFP chips don't sit in a socket so there's nothing there for you to be able to clip a big heatsink/fan to.

Those look like VRM heatsinks or something.
iulianv, I'm not sure what exactly you're looking for?
Is the CPU mounted directly on a (mother)board, or is it kinda like a very small square PCB with the chip on the top side and the pins on the bottom side?
