RE: Removing top cover...

My understanding is that all the A1 models use the ribbed cover as a heat sink. It is coupled with thermal paste to a metal (aluminum?) bar inside. The output transitors are mounted on the bar.

The heatsink cover is working properly when running hot. It is drawing heat away from the bar/output transistors.

The fact that the temperature has remained consistent all these years is a good sign that the integrity of the thermal coupling is intact. In fact a "cold" cover would indicate an internal issue.

The fan you bought will help the cover dissipate the heat faster and allow the temp to drop to the touch and internally.

Excellent fan suggestion by Duster in that it can work vertically.

Overall good idea to cool things down to prolong the life of your amp.
