sign of heat pad to hot?

[andrewrks123]

I use an infrared digital thermometer to monitor temperature:

A thermostat and/or rheostat to control the output of the heat pad are essential, I use the temp gun as a backup for double-checking.

Most heat pads run too hot, ~115-120F if uncontrolled.

thanks but then what should i do if they run to hot! theres no dial to turn them down!
