Hey Lisa, Thanks for your quick reply. I have the X-C1 V2.0. should i remove the jumper cap for it to work or keep it there. The documentation mention only that Remove the jumper cap on "Fan FS" PIN of X-C1 V2.0 will lead to getting the fan to run on full speed. it doesn't mention removing the pin to get the script to work.so should i remove the jumper cap and test ?
