is it possible to turn down the voltage on a ddc, say by using a rheostat or whatnot, to slow it down? im looking at making the pump a little more silent and i dont really need uber amounts of flow atm. cheers guys
Well according to a bit of googling the input voltage ranges from 6-13.2V, although whether that'll actually alter the speed I don't know. The D5 Vario was the only one (iirc) that would do what you want, although it's a bit late now... If your pump is too noisy I'd consider moving it, or getting one of those rubber mounting kit thingies, like you see for fans.
I believe you can. I landed one slightly used a year or so back that was branded....can't recall branding , but it had a 3-pin (power, ground & speed sensor) fan connector on it instead of the usual 4-pin molex connector (which of course is only using two wires) with the speed sensor separate. Alternatively, there's also a controller for the DDC made by Koolance ( IMHO ), but it's $20 or so. It's a small control board with a rheo on it for their branded DDC. I'm sure it works for any of them.
You can ajust the voltage, or stick onto a fan header, then onto a fan control. OR you can get an AquaComputer controller with a USB connection for it.. Those retail at about £18 though.
hurrah, cheers lads. dont need to alter it too much. just got the system down to the point where the only noises i can hear are the hdds click and the pump vibrate, so this'll hopefully silence the latter. then i just need a massive amount of lead or something equally stupid to silence the hdds with.
Yes you can but make sure that the fan controller can handle the amps. I had a D5 on a fan controller which had the required spec to handle it, but the heatsink on the fan controller almost reached melting point, the temperature inside the PC increased by 8c.
Ensure the fan controller can cope with 18w minimum per channel if it's a DDC3.2 18w model. If it's a 9w DDC, then the fan controller needs 9w per channel.
