Would you still need a heat sink/fan if you were using an 040 that was actually rated for 40mhz?
Yes. The 40 MHz part is made exactly the same as the 25 MHz part, so you'd definitely need a heatsink at minimum. On the other hand, if you can get your hands on a Freescale made m68040, they will run almost cool at 40 MHz without a heatsink.
