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?
I'm not sure there's a safe speed to run them without a fan. They get pretty hot.
And also these work better at higher speeds, so it doesn't really make too much sense to run them slowly, and therefore it doesn't make too much sense to run them without a fan.
You can get a PWM controlled fan that is pretty much noiseless and you would be able to run the compac f at full speed without worrying about it melting down or causing a fire hazard.
