I am finding this whole experience with bitfury very annoying. 

Glad to see that I am not alone.

I have only seen the H-cards run for a few minutes before the overheating starts.

I don't want to waste time with adding heatsinks, or fine tuning voltage. I just want these to hash.

I really think that pushing the default config for the h-cards to the bleeding edge of performance was a bad idea.
