Scythe Kaze master Mofsets? reaching 91+C with 2 fans attached within specs??

[Diverge]

Their design and idea is great, however the implementation and correct use of parts could be better.

Would it be possible to replace the potmeters with ones that are more reliable/can handle more amps? If so, what specifications would they need?

The pots aren't usually part of the output stage. They control input to a much smaller transistor, which drives the output transistor.
