A bit of background from me first, I was running a 7700, and switched to a 5700. 7700 = hot hot hot, 5700 no problems at all.

Agreed. The ZX-5 has one of the closest fitting bodies I've ever seen. I cut a hole in the front window and it helped, but it was still hot.

Yep. 5700 is much better, 4600 better yet I think. The 7700 I had was fast as heck, but ran very hot. I can't imagine the 6900 would be much better.

As a bonus, the runtimes were much better as well :).

I agree 100%. I had a similar experience, I just didn't gear up because the 7700 was pretty insane fast.
