Hello,
I am currently in the process of upgrading the fans for the KPA3 100 Watt
Amplifier module because the heatsink temperature gets too high for my
liking. I am upgrading both fans to a fan with higher CFM output. Last night
I hooked both fans up to the KPAIO module to test and see if they will work.
When I am on fan power level one, the fans try to but are unable to start
up. I have to bump them to start them spinning. Power level two has no
problem spinning them up. When I went to power level four and then brought
the power level to one, the fans did not have any problem continuing
running. The fan specs can be found here

Is there any components that I can add in line to provide the necessary
power to start the fans up at power level one?
Thanks
Brian Binkley
