    I would not get the ppm as you would have to have the pulse width modulation ckt.

    Yes it is a Fenner Belt. I put it on the machine a short time after receiving it. The OEM Belt was horrible and would vibrate violently at high speeds. Noticed an immediate difference.

    Fenner belts tend to whine a bit when new but soon quiet down. After 5 years mine is very quiet and the sides are highly polished.

    Ken,

    You would want the 3 wire fan. This is a simple DC Fan, red and black source power to the fan and the yellow wire is tach feedback to the controller. The 4 wire fan is a PWM fan using a 3 phase motor and require a PWM controller to drive it.

    As for a Power supply, I added a 12VDC Meanwell Brick some time back for lights, fans, whatever and just use it. You can see it in the photos below.

    I see that Noctua makes an IP67 fan but it doesn't appear to be available in a non-PWM version except for 24 volt operation. What fan did you use?

    It looks like the Noctua F12 IP67 fan can just run without the PWM (presumably just not connecting the PWM wire). Otherwise you could probably just put 5V on the PWM pin and run it at full speed.

    NF-F12 PWM --> "Can I run 4-pin PWM fans on 3-pin fan headers?"

    I finally ordered a fan and it should be here in a few days. I'll post some pictures of the installation if paying work doesn't interfere too much! Thanks to everyone for their help!

    Nice find that is definitely a good fan per the descriptions I just read, will also look at adding this fan soon - man, I got to stop the upgrades soon . Please let me know if you are interested in selling the cad files or the printed part, your design seems to be very effective and simple. I am all for simple solutions

    Thanks

    Looks awesome! How is the air flow in comparison to the built-in one?

    I balanced my fan by putting some tiny screws in the fan in certain locations, but it is still not perfect. About 75% of the vibes are gone though.
