The AntMiners get hot (and i'm overclocking them to 2.0Gh/s each), i've put some distance between them with extension cables and stuck them near a draughty cold window. Now I can touch them without melting off my fingerprints
Get a USB fan to cool them down.
+1 to that!
Mine were too hot too touch without a fan (way too many "hot potato" moments), but with an arctic cooling breeze fan pointed at them, they're practically cold to the touch now! (each one at 2GH/s and VERY close together on the hub)
! I have one of those fans on my USB hub with 9 antminers. Also clocked at 2GHs, but they're pretty hot when I touch them
I have mine near a window with an Arctic Breeze USB Fan on them and they're cool to the touch
