Link, comment follows. It should get warm. It's a power supply. But let's read http://www.rospa.com/productsafety/articles/temperatures.htm
Your product definitely is under the 60C mark (140F.)
Sorry but I don't think it's overly hot.

I recently got an Inspiron 8600 and a PA-10 power adapter (90 Watt). The adapter gets rather hot but I do not know whether or not this is unusual for this type. As a test, to achieve maximum load, I put in a fully discharged battery. I then let the battery charge while running a 3-D demo at 100% CPU utilization and a good workout for the graphics card too. With an AC power meter connected in front of the adapter input, under these conditions it consumes about 75 to 80 Watts of actual power. It gets so hot I can only touch it with my hand for a few seconds. How hot do these adapters normally run?
