motherboard fan connectors - manufacturer and type?

Hi,

I've a graphics card where the fan connector is a little 2 pin job.
It's not the same as motherboard fan connecters (molex KK AFAIK) in
that the PCB header is shrouded on all sides (MB ones are open except
for plastic side clip). The cable socket has a plastic retain barb
molded on the side.

Any suggestions for manufacturer and type?

TIA

I take it you want to replace the fan.

If It Were My Computer (IIWMC) I would cut the cable to the old fan
and cut the connector off the new fan and splice the two cables together.

OTOH, if you really need the connector info: what is the pitch
on the new connector? 0.1", 0.05", 2.5mm ... and what is the
pin size? 0.025"? .... What is the plug dimension, what is the
shroud outer dimension? ... date of birth ... mother's maiden
name ... name of pet ...?

Oh, it's fun to charter a consultant,

- wait, haven't I heard that somewhere before ...

No, the fan is on a graphics card (Gigabyte FX5900 PCI-E) and it b^&*!
noisy (compared to the shuttle it's in). It's a special heatsink/fan
assembly and it seems to be glued to the chip so replacement of the
fan is not an option. I just hope it never fails! Possibly if I were
to warm the entire board it might come off - it could be a phase
change heatsink pad but instead I'm building a quick circuit to
control the fan voltage from 0-12V over the range 25C-50C on the
heatsink. In normal use it seems like the fan is not needed (you can
software sense the internal chip temperature), or at most work
acceptably at a lower, quieter, speed.
If It Were My Computer (IIWMC) I would cut the cable to the old fan
and cut the connector off the new fan and splice the two cables together.

But this would probably (certainly ?) invalidate the graphics card
warranty so not recommended :).
OTOH, if you really need the connector info: what is the pitch
on the new connector? 0.1", 0.05", 2.5mm ... and what is the
pin size? 0.025"? .... What is the plug dimension, what is the
shroud outer dimension? ... date of birth ... mother's maiden
name ... name of pet ...?

It fits a molex KK header so 0.1" pitch but could be 2.5mm. It's
smaller than KK and shorter in length. I've seen these before on PC I
think so they must be fairly standard.
Oh, it's fun to charter a consultant,

Chartered as in Royal Charter. Similar to your professional engineer
or the term engineer in Canada and others. You have to pass exams,
and peer review to become chartered. In UK you can't just call
yourself a chartered engineer like you can just call yourself an
engineer.

Merry Xmas
