Swiftech MCP655-B on a 30-watt per channel controller.

post #1 of 7
Thread Starter 
So I just ordered a Swiftech MCP655-B, upgrading from an EK-DCP 4.0, which is kind of loud, is the MCP655-B going to be about the same? Or less noisy? Or less likely, even louder??

But mainly wondering is it OK to run that pump off of a fan controller period? And if it is alright, is a 30-watt channel enough to push the pump? Looking for those with experience with it, any advice would be greatly appreciated thumb.gif

Or just don't worry about it at all and run the pump 100% all the time? biggrin.gif

Thanks

Maybe, it draws around 12 or so watts, but I also don't trust fan controller specs much. I've tested so called 30W fan controllers that fail with as little as 20 watts.

I would think it'll be ok if the controller has a large heatsink to dissipate the heat and you have good airflow right there.

Just be careful with a fan controller, if you accidentally bump a knob to less than start up voltage, the pump would fail to start and you would have no idea unless you had some sort of RPM warning/alarm setup as well.

honestly at that point i'd just use a standalone rheostat, or just grab one of these koolance voltage controllers you won't be able to run it super low, but you can over-volt it if you want


i thought the d5 was pretty quiet either way if you mount it right

Mine has been perfectly silent for me. Except for my first fill. It started to get bubbles caught in it but the problem fixed itself as quickly as it came.

I'm using the same pump (MCP655-B), with a Rheosmart 6 fan controller. It works perfectly fine and with no noise.

OK well thanks for your feedback guys. Just got the pump today, waiting on a couple more things before installing it. I was gonna test it out anyway before putting it in the Switch, guess depending on how it sounds then, I might just be running it 12 volts 24/7.

I just recently got a MCP655 variable speed pump and I thought It would be as loud as my DCC 12v pump that makes a humming noise.. I was shocked when all the air bubbles finally got out of the loop that it was completely silent.. I didn't even know it was still on.
