Yeah, this would be pretty easy, although there really isn't such thing as a good and quiet 92mm fan. Nowadays either 120mm or 140mm are the standard and are therefore available in may configs, optimized for air flow, or static pressure, or a balance between the two. Also, some have better noise signatures that others depending on orientation, resistance to airflow, and where in their operating RPM range you run them. They also make (or perhaps made) fans with temp probes sticking out of the inside of the frame to measure temp of the air flowing through the fan and automate the speed based on that temp. That curve can't be modified, so if the way it was tuned was unsatisfactory, nothing to be done unless you wanted to mass with putting some resistors into the circuit.
I have been building custom PCs for probably 30 years now, but have only really gotten into custom water cooling loops in the last 5 or 6 years, but in that time the proliferation of parts to support the industry has exploded, so there are probably plenty of options on how to mount and power the fans, as well as materials that are easy to modify to clean it up a bit and make it look OEM. Sky is the limit once modding comes into play! Or just keep it simple . I am about to do some rearranging to move my HA-1 to my main desk, I will check it out for options. If you want to look around at parts, fans, etc. it is performance-pcs.com, the only major custom PC shop with a good inventory for custom cooling left. Unfortunately, it is also the ugliest and most poorly designed webshop I have ever seen. I usually figure out what parts I need somewhere else and then just search their site to get to it.
Also, I have seen a bunch of interesting solutions being released as laptop coolers, which vary widely in approach and design. It is possible one of those would just work... perfpcs may have some of those, but Amazon would probably be a better place to check.
That said, this being a class A amp, it is designed to run hot. I recall hearing that good amp designers would account for the expected steady state operating temp range of the amp and optimize part selection and performance for that range, where a range was required as ambient temperature would affect it. That was what explained why some folks recommended a warm up period for class A amps before use. I dunno if that is true... but I heard it frequently when I was into 2ch and home theater in the 90's. Given that, rigging up cooling solutions was discouraged.
My HA-1 does run pretty hot so I used an IR temp gun to measure some parts through the mesh in the top. I don't recall what temps I saw other than I wasn't too worried about them. And I have never experienced any of the issues expected from overheating causing protection shutdowns or anything, so I never really worried about it.
