You can also check if the 1541 can be set to 240V input voltage. If yes, 
do that and it will get less hot.

Take a look at the transformer and if there is a another wire on the 
input side, measure the resistance against the other 2 input wires. It 
should be obvious what you should measure if it's the wire for 240V.

The 1571 with a transformer PSU has ready to use jumpers on the power 
supply PCB marked 220V and 240V.
