Hello,my computer technician put the cables of the power supply behind the motherboard...this cables are in touch with motherboard is it possible to cause an increase in temps?
 
in theory its possible to increase temps around a power lead...
it can happen when electrisity is flowing 1 way through the lead and the oposite way on the circuit board... between the 2 you may get an em field which would increase resistance and that increase could produce higher temps... but in a pc the chances are it would be much less than 1'c as theres just not enough unshielded wire to create the magnetic or electrical fields as the voltages are pretty small..

when 2 em fields cross they create eddies and its these eddies that increase resistance. this in turn raises temps... but if you loop the wires you can increase the field strength which again will increase resistance in the wire causing excess of heat,
so yeah like i said in theory its possible but in reality its unlikely.
