Out of interest I just measured heat off my Blizzard 1230 Mk1 with a QFP packaged 030.
The CPU (mounted underside like Blizzard 1260's) was 62 deg C after 30mins! I had the AGA game Tornado (3D flight sim) running the 'drone demo' from main menu.

Numerous other parts of the accelerator board were over 50 deg C.

Im not a fan of the QFP 68Ks. They cant get rid of heat very well.

I see on eBay/web there are lots of Thermoelectric Coolers. The profile looks low and the size seems 060 ish. Plus they are cheap.
Not entirely sure how this would be wired up or if the 060 would generate enough heat to be viable. So the heat generates a voltage and to dissipate that we could run a fan? Or just burnt off via an LED or resistor.
