486dx33 at 66 MHz ? Well, I don't want to be picky, but wouldn't
this result in 66 MHz CPU bus ? Sounds a bit off for 486 Boards.

Jep, the most notable CPU is still the AMD 5x86 (486dx4/133 with
extended cache) - I have them running at 4x40 MHz == 160 MHz without
any problem - only for high load apps the cooling must be presen,
a Linux (web) server can even run without a fan.

I found it hard to run NMOS 6502 on more than 1.3 times their nominal speed.


P.S.: When designing a new cooler element/radiator, keep in mind that
      silver is a way better thermal conductor than Al or Cu.
