Currently OpenBSD won't automatically change clock speed unless running
on battery. To workaround you can either manually set to another speed
(in your case 2000 would at least disable 'turbo' which will probably
help with the temperature), or run "obsdfreqd" (not in 7.1 ports but
the -current port will build ok on 7.1), or use this diff - of course
results will be better if you can get the acpi problem fixed too.
