Cooler than the old Asicminers .333 in my hubs, U1 and U2 temps about the same.
5v at 5a PAdapter obn each hub - 5 per hub  35 to 42C with large destop USB fan resting on the cluster of devices.
110 is nothin. Temps taken with a laser gun on wide scan.

Without a fan of some sort they get hotter, 50 to 60c or so. Not hot enuf to melt hub or anything, it just cuts down their lifetime runnin hot.

ALL U1 and U2 set at .0981 volts for 2ghz average on bitminter. I like to allow 1amp per stick, ( I like the margin ) everything overbuilt, not stressed.

Thanks for the quick response man. So would you say that even with a fan they are still to hot to handle without gloves/protection? I'm waiting on my fan to be delivered, and as it stands I cannot touch them for more than a second without burning myself. FYI I'm running 5 on a rosewill 10 port. 5v 4a should be plenty

I am not qualified to answer that as a "Normal" person. I did mechanic/machinist work for 40 years, I can handle most anything hot others react to.
Used to ask people to "hold a wrench" I was using after it set in the sun for awhile, I handed it casual, they always jumped back and dropped it Smiley
Lot of fun, then I told them to not bug me as I was a bit hot, had been working in the sun all day. Asphalt I stood on was up to 138 degrees in summer, I worked in that environment all day every day, hell my under hat temp was way over 100 all the time.

Now you know why mechanics are "hotheads" Smiley

Retired now, just want to reflect from time to time.  Thank God I do not do that anymore.

My miners seem cool to touch, to me. they do not reach "melt the plastic hub temp" so all is well, I do not handle them much at all tho, they just sit and mine, since december when it was all asicminers .333 next would be chilis if I can get enough coin, 30gh for 150.00 when you can find them.
U1 and U2 are fine for now.
