Howdy Folks:
noob here - great site
trying to aid my iMac G5 - need to figure out an external power source for a Papst 4312L 120 mm fan bare wire -
Specs from Dander Den dont mention specifics - is this a constant 12 V
any one know for sure ?
cheers in advance

Sepcs for this fan can be found here
http://www.datasheetarchive.com/pdf/354035.pdf
It uses a 3 pin connection, The source can be from ~6v to ~12v @ 1.2W
It uses Ball Bearings & 1550rpm @ 55.9CFM
This fan was replaced by the 4300
N series
It has no temp monitor and isn't a PWM fan (hence only 3pin) so
the speed is set by the input voltage.
My guess is the MAC will use 12v by default.
Good choice on the fan! Papst are one of my favourite fans! They last forever and you never hear any motor/bearing noise when at very low speed. --> You can't beat the Germans when it comes to engineering ;)

Howdy Kenc51:
Cheers ya for the data sheet - I ordered bare wire - hope that means just 2 wire - Danger Den only list it as 12 volt - as this will be an external fan on back of G5 case - I will want an external power source to drive it - dont wanna mess with the Apple Guts
According to this spec sheet this 4312L input is 1.2 watts - this is what i was looking for -
Yes - i ordered this online when I saw only taiwan and china made fans only available at local big Electronics store - Agree - german equip is most prefer 'd
Cheers ya:
