Nice work! Promising results how did the cooling hold up?
They normally run much cooler than the erupters in the same hub. nothing accurate, i'd say 10 degrees hotter than normal, just bearable to hold the finger there.
Eruptors run too hot, touching them hurts.
I also have it furthest from the fans (should probably change that) so heat might be slightly exaggerated.
I might be able to get a photo of the hubs with my IR-Blue, wont be untill sunday evening though, I left it in the office.
