Depends on the motherboard implementation, I've built a half dozen PC's recently. The P4 AOPEN AX4SPE-MAX allow speedfan to control (2) case fans headers and CPU fan. The Asus P4P800dlx allows control only of the CPU fan. A micro-ATX Intel branded 865G board, forget the m/n, allowed control of case fan and cpu fan and the Shuttle MN31 IIRC did not allow control of any fans. If you do a search here for "speedfan NF7-S" you'll find a number of hits that are somewhat contradictory. But don't fret, the Globe fans will work in either case. If you can slow em w/ speedfan, great; they respond well to pwm. If not, just clip off thermal diode, short the leads together and wire the fans into fixed 5v from the a PSU molex connector. Globe fans will be very quiet at 5v and still provide adequate airflow for case cooling.

Could someone explain in details (mebbe even pics) on how to short the thermosistor on the globes?

I need to do this when I get home to hook it up to my fancontroller and am not to sure how :?

Sure, just snip off the thermistor. Then strip back the insulation on the two wires & twist em together. Wrap em up w/ electrical tape and you're done. Of course, if you like, you can do a more professional job with a soldering iron & heat shrink tubing. I found that the globe label on the fan housing is a big sticker. Upon peeling it up, there is a small printed circuit board underneath. The fan leads are all soldered to this pcb. I de-soldered the thermistor leads from this pcb, and replaced them with a wire jumper, then pressed the label/sticker back in place. Fans now look like factory 3-wire fans without thermal control.
