at 16.00 was the system powered on and
a higher temperature than normal observered
power/currents adjusted on power supply

readout errors - adjust power + power off/on
at around 15.30 did the temperature start to rise
with 2.5 degrees on a FEC card.
Most likely it was drawing more current.
Fell again after adjust and power cycle

From this can I not conclude any reason for it,
but it is clear that the number of channels
with problems are increasing. Seems to be in steps.
