Avoid the burn...
As above really...see how hot it gets, it shouldn't harm it, just cut out.
Something that might be of interest to you, i did have a thermal sensor relay cuircit from maplins, you can set the temperature to what you want and when it hits the sey temp it opens the relay. I have it installed next to my amp, so if it gets hot, the relay opens and starts up my fans and cools my amp.
