Well, points are not rewarded by how difficult it is to get a score or ranking...points are rewarded by how they rank. Which brings me to that I agree the points don't matter, it's the ranking that matters. And it will be screwed up by rewarding aircooling high points. If that is the case then you have to separate the enthusiast from extreme completely. And that does not seem like a good idea...
I do not think overclocking will be more popular be quick rewards, it's not candy crush...Overclocking requires a lot of time and effort, if you don't have the patience and interest you will never continue anyway. OC will never be for the masses. I'm fine with that, it's great fun the way it is for those of us who has the special interest needed.
