I've had my i7-930 overclocked at 3.7Ghz for quite some time, whilst remaining undervolted. (1.12v)

Having a large amount of room heat wise, I was wondering what the limits were for the i7-930's in terms of Heat, and maximum voltage for 24/7 useage.

Well, brought the voltage up to 1.2 and it's now stable at 4Ghz.
Temps don't go over 80C and according to an hour of IBT with 8GB of RAM, appears to be stable.

I keep my son's under 72 at 3.8Ghz w/ HT enabled. Hits 74 at 4.0 Ghz w/ HT disabled for gaming. He can select which boot configuration to load from a menu in the BIOS.

From the specifications for the processor:

Tcase (processor case temperature) maximum at 130W TDP is 67.9c
Tstorage (absolute maximum temperature while in storage) is 125c (processor junction temperature)

VID must not exceed 1.375V (absolute maximum rated value for Vcc)

I imagine going beyond these specifications will result in immediate irreversible damage. Getting close would result in decreased longetivity.

It appears i'm having a voltage regulation problem. Setting it for 1.2775v results in being fixed at 1.305v, yet setting for 1.23 (or lower) works as intended.

** Setting it slightly higher seems to have fixed this, apparently only that particular value I was aiming for is bugged and sets the system at 1.305v
