@paco @gsuberland but also, sometimes there's a contact that will break when temperature changes expand/shrink some part past a threshold. I've only seen this firsthand in the other direction though.

@regehr @paco the contact pressure should be more than enough to handle that unless it's a very sudden temperature change. but even then I've seen folks splash LN2 on running boards during extreme overclocking benchmarks and they continue working just fine.
