Are there suitable fans with tach output?

supposedly... you can get just about any fan with a tach output from most companies...

It's not exactly plenty of slim 40mm fans with speed sensor... I found two, but one was too noisy. This was only looking in the Farnell catalogue though. Did find another one that might fit, but it was 25mm only, so would probably need some modification to install it...

Checked this since I also requested two MAX6651 when I sent the request for the DS1721...

Genixia, still up for being bribed into adding PWM when I manage to make some boards for the 6651..?
