Erm as i've come to expect potential problem
I had the prommie fitted and then it was having problems so connected the usb bit to a spare pc to flash the firmware.
Little did i know the unit was running as it should while this is happening.
When i realised i thought hell why not start it up and take advantage of the cold.
No post. Not sure if its because the chip was sat with about 30mins of -50 action while giving off no temp but just removed the head and no water is around.
Came to take the chip out and the screw to release the chip is frozen so can't do anything for the minute
