Slot cooler fan w/rpm wire?

I'm looking for a slot cooler (small single slot hopefully)....it must have a 3-pin fan with rpm monitoring. Anybody have one? If so how quiet is it?
 
Thanks....have you seen my latest mod, a totally positive pressure Antec Aria.

This is what the slot fan would be used in. The main fan runs so slow (and quiet), the bios thinks the CPU fan has failed, and refuses to boot. I had to add a small HD cooler fan (with an RPM wire), attached to the CPU fan header. It tricks the BIOS and the thing boots normal. But I don't really need that small fan on the HD. A slot cooler fan would do this setup more good, as long as it would start and run quietly slightly over 1000 rpms.
 
I'm not a card carring member of the silent-set because my office/fort is in the back of a
deep 4car garage (my preference really) 1.5miles from two major freeway intersections 🙁

So intake air is filtered well to cool Intel 😉 I will read your linked thread later today.

They are OoS now but allelectronics.com had PIII HSF for $2.50. The 40x10 fan is very high quality w/tach wire and will be silent with the case closed at 5V. I use two over sinked fets.

Most current boards will permit disabling of the CPU sensor feed. Just use a tached fan to boot, then go into the BIOS and disable it.

Any other fan in your rig that has a tach feed can be hooked to the CPU fan header. Just put the yellow wire in a spare 3pin shell and hook it up.

There is only the one YL 120mm fan....it runs about 750rpms at start up. The BIOS needs to see at least 1000rpm, otherwise I have to hit F1 to start. I can find nothing in the BIOS to disable this "feature". Hense the need for a second quiet fan (over 1000 rpms), plugged into the CPU fan header.

A slot fan w/rpm undervolted to minimum would solve this little problem and be useful at the same time. I sure don't want to add any noise to this quiet box.....
 
I am not sure but I *think* disabling CPU Internal Thermal Control will shut off the need for a sensor feed.

I did look for awhile because this old fart did spot it about 6 months ago. A small encased circuit that plugs into the fan wiring to the CPU fan header that will multiply the tach signal. IIRC, it doubles the signal, so 750rpm would be sensed as 1500rpm.
It was not a controller with a built in alarm but a multiplier.

You might PM one of the WCed guys, like HardWarrior, into your thread because they have little need for the tach signal.

This device might do the trick....pretty pricy though. Plus I'm already using an external automatic fan speed controller, so I'd have the two devices in series before the fan. Lots of complication for the one little problem.
