E-fan stumble

There have been several posts about this with the general consensus being "live with it".
My question is, will this thing work?

How about if I use the ECU to control the fan, will it still stumble?

What ECU are we running here?

If you use your ECU then you wont need this.

ECU- Currently a 951 (N/A)
I have two fans, a pusher and a puller, both on different sensors, set for different temperatures.
I'll be Installing a turbo this summer and have a 781 ECU I'll be using.

So, the ECU has some sort of soft start scheme?

Are you talking about engine stumble when the fan starts? I notice considerable less since I switch to a Denso 100amp and upgraded the ground - still need to upgrade the positive side too.
