For german user, I will sell Chilly's from Lucko next time at ebay.de.

They have installed a fixed firmware which pre-heat the VRM's slowly so the heat up problem is very seldom now only if my internet connection drops more than a few minutes.
No hairdryer heat up is needed for them. So they run stable after flashing the work around firmware.

Check ebay by using search word Chilly :-)

Lucko, I hope it's ok for you. If not delete this post simply 

Cheers...
