I might have a solution for your problems. I just have to wait and see if it'll get done. Answer one thing for me though. If one has a product that can dissipate 2-3 times more heat then copper and with a little airflow (when vehicle is moving), would a fan still be needed?
Not saying my set ups are perfect but the fan is something I never had a issue with ?
I have 6 M.M.M's and a few have ben in for repairs, 1 has ben in twice but never a fan ?
Is the issue with wearing the fans out or them breaking from debris getting logged in there ?

I race weekly on 1/8 race tracks w/ large jumps.. the fans just give out over time from the hard landings I suppose.. notice they just released a 'new improved fan' so please don't think this has been isolated to just me. Most people I know have replaced the fans at least 1x. They are just cheapo computer fans after all, never designed for taking impacts etc.
Your "big jumps" on the track doesn't come close to the jumps I subject my trucks to.
15-20+ feet of air is the norm, and LOTS of hard ugly landings. I've killed a couple ESC's with these stunts but not the fan, go figure ?

With learning from what I have (A LOT) from Mr.BrianG over the last few years I agree whole-heartedly.
In 6 different trucks my fans never come on, and most are on 4s.
