Disabling built-in thermal control in fan

There is a Sanyo Denki fan I'm interested in (model 109R1212T1H162), however it's a thermally controlled fan with a built-in thermistor, which I don't want.

Is it at all possible to remove or disable the built-in thermistor, or no.

Also, if I can't disable the thermistor, what would happen if I hooked the fan up to a fan controller. Would the fan controller setting overide the thermistor?
 
Take a gander at this.

Essentially, you need to do the following to get the fan running at full speed permentally:
Temporarily short across the contacts of the thermistor with a screwdriver whilst the fan is connected to a PSU to check if the fans ramps up to full speed.
If the fan runs at full speed using the screwdriver trick, cut the thermistor out and solder a wire across where the thermistor was connected.
 
If I left the thermistor alone and just hooked the fan up to a fan controller, do you know if that would let me control the fans speed myself. Or would the thermistor still control the fan in some way. thanks
 
A fan controller would still cut down the volts going to the fan. . . but the fan would still have a heat-controlled variable resistor in there doing its thing, so it would still slow down. . . just moreso.
