It's not an issue with overheating the CPU, it's an issue with stability. When I was running unencrypt with the original setting, I found that my box wasn't acting quite as it should after a couple of days and that behaviour seemed to clear up when I set it to only run overnight. At the time, I didn't want to risk making boxes unstable, resulting in unnecessary warranty returns of boxes with custom firmware on them - that would probably not do the project any favours in the eyes of Humax.
However, it now sounds like more and more people are running it all the time and are not experiencing problems, so please give it a go and let me know how you get on. The simplest way of making the change is to use the file editor in the diagnostics section of the webif and to edit the file /mod/var/spool/cron/crontabs/root so that the line
Code:
1,31 1-6 * * * /mod/sbin/unencrypt "/mnt/hd2" > /mod/tmp/unencrypt.log 2>&1
becomes
Code:
*/10 * * * * /mod/sbin/unencrypt "/mnt/hd2" > /mod/tmp/unencrypt.log 2>&1
Save the file and power cycle the box and let me know how you get on.
