Related: I think I've read there is a way to lessen the load but I wouldn't have a clue how to do that, assuming I read correctly that there is a way.
Using the throttle directive as uncwilly suggested is one way. Reducing the number of cores in use by prime95 is another. Lowering the clock rate is another.

My guess is that cutting back on cores may not cost as much performance as the other approaches. While I've used throttle for years on a system whose cpu still seems fine, I wonder what the frequent thermal cycling it does means for reducing processor life.
