does it read 35 degrees C  when the amp is cold?   and is it that hot in 
your shack?    if this is the reading from a cold start I am guessing 
the temp sensor is not calibrated correctly and it is reading quite 
high  possibly falsely indicating a high temp when its not really that 
hot.   either that or the ambient air temp is to high.
