hmmm...alright, well, i might have been exaggerating just a little. the 60mm medusa i had was not in exactly the best shape and it has comparable temps in the same setup geared for the same speed at a similar max rpm. the bearings were getting pretty rough too in the medusa.
i do think these would do alright in a maxx or revo geared for ~30mph. once i get my revo fixed, i will try it out and might finally have a reason to use the blower.
