Yep sorry I didn't comment on this before but yes base freq may not be suitable for fans...especially the mag-lev computer types. Generally its fine to run the fan from 9~12V ...depends on the HSF performance. Generally the faster the fan the better cooling but some lower fan speeds are acceptable. Depends..If we get a suitable TEC @9v DC we have to test if the fan can remove the heat enough at this voltage. If we are talking >2.5A...I'd say yes....at a guess.

Just going to buy a cheap TEC controller wit ha bigger range doe TEC testing. Its no PWM...but you get a good idea is the TEC can fit the range we need.
