When you touch it with a wet finger and you hear a
hissing sound, you know it's >= 100 oC:)

Or if you touch it with a dry finger and you hear a hissing sound....

But then you lack the protective water film
between the hot surface and your finger. You
most likely will do this only once:)

Code:

BXF 1: 52.2C | 5.333G/5.322Gh/s | A: 328162 R: 330 HW: 201 WU: 74.4/m

These have temperature sensors, and that's with an 80mm fan pointing at it. Without the fan it gets to over 90 degrees and then I pull it out with gloves on for fear of it melting. This engineering sample doesn't shut off even after I close cgminer so it just keeps getting hotter unless I pull it out.

How the designer of the Red/BlueFury cools his down.

Does he really do that? I might buy one off of the store right now and test that out.

Anyway, I'm working on some auto protect feature for the Bi•Fury firmware that shuts down the ASICs when they get too hot.

Just be wary, these things are thirsty for power. Mine stopped working when I moved it around to a different USB outlet on my pc till I realised it was because it was sharing the same power line as the ~~bpmc~~ redfury I had. Putting them on separate usb hubs even directly on the pc made a difference...

Original RedFury. BMPC = Dead or Non-existent.

How is that RedFury in comparison to the BiFury? Guessing both pretty stable USB miners eh?

They both just keep on hashing without any issues whatsoever. One is warm and 2.3GH, the other is 5.3GH, dangerously fucking hot and needs serious cooling.

EDIT: But it was an engineering sample and I have absolutely no idea how representative it will be of the released hardware!

Temperatures above 50 oC can feel painfull for humans,
but are ok for electronics:) Did you take the actual
temperature?

And a little fan can do a lot as I found out with my Block Erupters:

I was going to get 20 for my Anker hubs, but after researching it appears that each hub will only support up to 6? Anyway, I got enough for 5 for each hub, just in case. It seems like these will be profitable in the very long run...

When do orders placed today get shipped?

Well, I just bought one off the website. I wanted to get my hands on one and the prices these things are going for on ebay are insane.
