OverSpeed Fan!

I have a small problem with my current fan set up. I have a 12 PAPST fan blowing air directly on my CPU from the side of my case. Keeps Every thing at good temps , which is good but my chipset fan gets a bit of a speed rush with all the air coming in threw the side fan. It seems to be wearing the chipset fan out due to speed. I just put in my second chipset fan in 3 months. I put a blue orb that i had spare this time and my monitoring software reckons it is spinning at 21039 rpm belive it or not it is still wearing out fans. What should i do to fix the problem?? Maybe I could funel the air a way some how but were too???????????:disgust:

If it's getting so much ventilation why not remove the chipset fan & just leave the heatsink?

If there's that much wind going by it then it will be fine with just the heatsink.
 
I found a company in Australia with a Zalman NB32J Gold passive northbridge heatsink.
I gather this is the same thing.
 
How big is this 12 PAPST fan? I really doubt that a fan could wear out a chipset fan. And that 21039 rpm reading is totally messed up; no fan spins that fast; even hard drives don't spin nearly that fast.😉
 
he means that he has 12 pabst fans, not a 12 pabst fan ...

his computer moves about 6 M³ air each minute I think ... now that's a load ...
 
Thanks all for your help it is one 12cm papst fan type 4112 GXM and it is straight above the chipset.
I pulled the side of the case and disconected the power to the fan. But the chipset fan still gives the same reading must be a faulty reading somehow. The first chip set fan burnt out really quickly though.
With out a chipset fan system temp is normally 1c above ambient with the blue orb on it the temp is 1c below ambient or so it recons. I have used three diferent monitoring programs and still the same. So fingers crossed it all right and the board does not get fried.
