BL20p G2 Overheating

[Tony Cresswell]

We have 2 blades (in the same cab but different enclosures) which are displaying errors that say the Temp Sensor #2 (CPU) is overheating and a shutdown will occur. 10 seconds later another message says its below it threshold and the shutdown has been aborted.
The enclosure is fully populated and the 2 blades are not near each other and no other blades are affected.
I would say it was a h/w fault but its a bit of a coincidence 2 blades going faulty at the same time?
Help!
