fan control

[robertgraham]

A cracking job exited because it exceeded thermal limits. That's a good feature, but a better one might be to increase the fan speed instead of shutting down.

I manually configured the fan to run 100%, and restarted the job. After 15 minutes, temperature is 59C -- which is actually lower than the 68C it started with.

Of course, this could be a bad feature if running the fan at high-speed for too long could hurt it.

After 43mins, temperature is now 58C with fan at 100%:

I disagree. We had the same discussion on here: http://hashcat.net/forum/thread-774.html

You are probably right. Your time is probably better spent doing something else, like tweaking kernels, or getting my 7970 working :-)
