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.

Would it be 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?
 

the last resort

well, no. im not actually sure what would happen. the thermistor measures resistance, which changes based on temp, so cutting it out would do something, not sure what.

hooking up a fan controller would control the fan speed from 0 to whatever RPM 100% is for that temperature. I noticed this with my AMD stock fan. If I turned the fan off, waited for the case to get warm, and turned it to full, the RPMs would be near 5000 instead of 3300 like normal. As soon as it cooled off again, it would be at 3300.

Were you able to completely control the fan speed by hooking it up to a fan controller, even with the thermistor intact. Did the thermistor exert any kind of control over the fan while it was hooked up to a fan controller, or was the fan speed completely controlled by you (via fan controller). thanks
