I have a towerized A1200 with a Blizzard PPC and 68060. The 68K side is completely stable and the fan that is on the board is sufficient to keep it running smoothly (it was replaced when the 68060 was upgraded). The PPC however has a solid plate heat sink and shortly after use becomes unstable due to heat issues.
I've tried a couple of times to solve it and they all worked for a while. Things like velcro'ed fans and what not but there is no good way I can see to attach a fan on there. Can someone recommend an actively cooled solution?
