+100 @ philipma1957

I turned handles "outward" and added a fan, FINALLY got these Tubes to stop with the thermal runaway. Also +1 @ friedcat "they" handled the RMA on my burned up board, no additional costs.

Gee, I can't see why you guys are having any thermal issues at stock clock speeds. My 3 have been running continuously at 2.4T in the quite warm (90F+) mining area of my basement. With 1 fan, though the handles are pointing outwards. I hate to mention this, I'm only trying to help, but you guys are peeling the plastic from both sides of the thermal pads before use??? Embarrassed

I had to ask since my three have been amazingly reliable and robust so far...
The air coming out the center is as hot as a BIG blow dryer, and the chips are too hot to touch, so I'm wondering about longevity, but as long as they hash for six months I'm fine. Wink

I remember a discussion about the fan arrangement and whether it should push or pull air through the tube. I set mine up to push since I didn't want the fan and it's bearings to heat up because I thought that would cause flow issues. I have had no problems with the stock fan in a push config at clock of 280 and my 2 tubes are getting ~~1.7 T~~ more like 1.68 T.

I've got 2 with fans arranged as pull, clocked @ 290 Mhz in a quite warm 32*C+ basement with a bunch of other miners. Getting the same speed as you on average, going to try 280 see if I get any better.

You're running in a lot warmer environment that I.
One of these in in my basement ~23C and one upstairs ~ 25C
