The only reason I changed the Hz was for the new 2014 Corvette Spal brushless fan calls for a 100Hz signal. If you are still using the stock fan controller stick with the 128Hz. 128 Hz drives the new brushless fan fine as well but you would need to adjust the desired fan %. With the brushless spal and 128Hz, the fan is at max rpm at 70%. With a 100Hz signal, it takes 90% to max the fan out.
The spal brushless fans have the controller built right in the back of the fan.
Hope that makes sense?
