I have been looking at getting a System Saver for my fanless compact macs, but I'm not really keen on the integrated electronics or the price. I searched to see what people had built to add an external fan but didn't find anything.
I printed a speaker grill and added a $6 80mm fan and attached it to a silicone cake pan I cut up and soldered a power plug for a 12V adapter.
It makes a big difference - After running for a couple of hours, without the "System Saver" the temp at the top of my Mac Plus on the analog board side hit around 50c. The hot spots on the outside analog side board of the Mac were around 38c. With the "System Saver" the temps for the same period of time at the same locations were 32c and 35c, respectively.
It would be nice to get the analog board side temps down further, but by exhausting all of the hot air that seems to sit at the top of the Mac's case, I can't imagine this isn't an improvement regarding component life.
