For Sale:
[For Sale] D5 pump

Will Ship To: US50, US48

Please read the details if you consider buying this. This pump is usable but is not fully functional, and hence is offered at a discount. I want to be very clear about what is working and what is not working.

This is Swiftech D5 PWM pump, or was, originally. What then happened is I once accidentally plugged the RPM/PWM header into the motherboard with one pin offset. Since that mishap, the pump always reports zero RPM.

Furthermore, when my motherboard sees no RPM readings, it does not send PWM signal. I suspect that if the pump is used with a fan controller that always sends PWM signal even when no RPM is read back, then PWM control would actually work. But I have no way of verifying this. Hence to be on the safe side, let's assume that PWM control is in-operational as well.

So, as a work-around, I kept the PWM/RPM header unplugged, and only connected power. In this mode, the pump always spins at default RPM which I think is around 50-80% [update: 60%, thanks to @geort45] of the full speed. So essentially this is now a fixed RPM pump. I used it like that in my loop for some time, and it was actually working fine, and was still creating enough of water flow. Eventually I still ended up replacing it though.

The pump has no mechanical issues (motor, impeller, etc.), and had been in use for few months. Perhaps someone with enough expertise can re-solder the circuit board to bypass the RPM circuitry, and that would make the pump always run at 100% RPM. I don't have enough knowledge to do any of that though, or to even tell if this is really possible.

So, here it is. I offer this pump for sale at about half the price - $50, including shipping. Preferred payment method is PayPal. O-ring and stock mounting ring are included. What you see in the pictures is exactly what you get. Hope someone finds it useful, as a back-up part, for flushing / leak testing / etc., as a source of spare parts, or maybe it can even be repaired.

Oh and if you want, I'll throw in stock D5 pump top at no additional cost to you, just let me know.

Hi buddy! I was very interested about the price, but it googled around and it seems the default speed is ~60% if no PWM wire is connected frown.gif

Yep, that's right in the range that I suspected. I amended the first post with your info, thanks!
