is it okay to run the compac f with 200Mhz without a cooling fan? I tried it but it gets very hot. What is the maximum recommended working temperature for it?
Define 'very hot'. If you can touch it for a few seconds and not get burned it's fine. Plus even with a fan, the f;s still refer to run at a quite warm temp. Around 125F is ideal.
The other thing is that really prefer using a
starting freq of at least 300MHz. Just the nature of the chip used (and most mining chips)
