The heat is caused by IC001 which is a regulator that is mounted on a completely inadequate heatsink on the power board. This component gets very hot during normal operation.
The regulator will usually last a couple of years, depending on how often the machine is used and then start playing up. The symptoms are intermittent operation, continuous self checking and rebooting, not being able to read discs and so on.
Eventually the component can short-circuit, burn out and take other components with it. The on-board fan is thermostatically controlled. It does not operate all the time, only when the unit gets hot enough. By using an external fan, you are keeping the unit cool enough for its own fan never to cut in. The additional cooling is probably squeezing a bit more life out of the regulator and is stopping its own fan from operating.
I have repaired lots of these and have never found a faulty fan, or fan switching fault. There's always a first time of course.
It is more likely that the regulator IC001 is faulty and if you are technically skilled, I would suggest you seriously consider replacing it. Use some heatsink compound and an extra heatsink, and it will probably do the trick. The regulator is an STRG6353. You can get these easily online from a number of outlets. Don't attempt a repair if you are unsure of what you are doing. Regards..

Yes, it would not recognize any type of disc. The disc icon was always present on the display even though no disc was inserted. Also, mine went out while recording from HDD to DVD. Panasonic had mine repaired in two business days and it' s working great.

You could try Changing the Remote Control code for your DVD recorder. If you have more than one Panasonic device, there's an option to give each device its own Remote Control code. The Default is DVD1. So for FixMick, it sounds like someone may have changed the Remote Control code on your machine to DVD3. For Dador, someone may have changed the Code to DVD1. So you'll need to change the Code on either the device or the Remote to make them match up (see page 19 of the DMR-EH65 Users Manual ... you can download it from the Panasonic website)
Sorry FixMick. I don't know why your display isn't working.

My remote is not working. When I press a button, I get the following message on my unit: U12, U30, SET #, CHK REMOTE #, or RC #. What can I do to fix this? The message displayed means that the remote control and unit are not communicating and the remote needs to be programmed. To program the remote, press and hold the same number that is displaying on the unit and the [ENTER] or [OK] button for more than 2 seconds. For example, if the unit displays “SET 2”, press and hold  and [ENTER] or [OK] for more than 2 seconds.
