You're kind of going about this the wrong way.
You shouldn't have any problems cooling a 7970. 70F ambient temp is irrelevant. Are you forcing the fan to 100% before starting a run?
If the fans are at 100%, then it sounds like you have an OEM design card, which, as has been explained on these forums multiple times, are designed for gaming workloads, and cannot cope with compute workloads.
If switching out the card for a reference design card is not an option, then your next option should be to underclock. Try bringing the core clock down to 850-900 Mhz and see where that leaves you.
