i dont understand why they add this heatsink, i have 50 U1 and heat is not a problem at all

Because the U2 is intended to be overclockable out-of-the-box via software control. Naturally, people will be trying this and, knowing nothing of how heat transfer works, would be running into issues with them overheating with the U1's thin plate heatsink. I suspect you could still make the U2 overheat, too, anyway.

I figure if you've got 50 in one of those bulky USB hubs, a custom cooling solution is probably not out of reach if the physical dimensions throw a spanner into the operation. Or just get another hub Wink

running 1.95 ghs on each, 10 pcs in each hub and 2 fans..

in my country i also get free cooling from outside.. Cheesy

my basement is always cold, even with 50 antminers in the room.
