Using a fan controller to control pump noise

[Kninetik]

Got a slight problem here. My MCP650 is too noisy to take naps with on and after 4 months, I've had it. I ordered a Noise Isolater 5.25" Fan controller to go with my new fan setup. I was thinking of hooking my 4pin MCP650 into a 3pin adapter, then running it to the fan controller so I can adjust it to full during the day, and slow it down at night.

The problem lies here. The pump takes 24Watts 2.0Amps at 12V full running. The controller's maximum is 20Watts 1.67Amps per channel. What will happen if I run it for days at maximum? Will the unit blow up? catch on fire? just malfunction quietly?

I may have found a solution to this but I need experts on this. The controller's max is 20Watts PER channel. There are 3 channels available. So what if I split the 4pin into TWO 3pin molexes, and run each to different channels. Will that be able to safely run my pump at its maximum for months without dying?

I had one of those pumps and tried to control it with a fan controller. The damn thing still makes an irritating noise even with it turned down to like 9 volts. As far as the fan controller goes, it was fine at full power, where you run into problems is when you actually turn it down. I actually recorded temps over 200F on the heat sink of the channel it was on. That was on a Vantec Nexus controller and it just flat-out fried my Fan Master controller.

Your best bet is to change that thing out to a AQX-50Z or a MCP350. Both have great performance and are whisper quiet. If that doesn't work for you then maybe wrapping the pump in some kind of sound dampening material. Wish I had a better answer for ya but that pump is just a loud piece of crud.

Good luck.

Ah~! There goes my hopes of a quiet pump. Im definately sticking with this because of its great flow rates, naturally 1/2" and ability to be hooked directly into the PSU. Time to wrap it in some type of material! Thanks

I just put my 650 on a fan controller and it is still too loud. I may replace it with a modded 350. Also, be careful of your pump temps if you are going to rap it.

Hmm this is getting complicated. I assumed most of the heat gets transferred into the water. Im just going to have to put padding on the area surrounding the pump then

You might try running the pump on 5 volts from a power supply molex and see if it comes on. If it can function there it should still push enough water to keep your system plenty cool, in all likelihood. If it does indeed work you may just want to add a switch to change between 5 and 12 volts when you need the extra cooling or when you need quiet.

As for a fan controller, pumps use tons of power and most controllers are only able to supply enough for fans and maybe lights, relatively low-power devices-- a pump is likely to fry them.

i was thinkihng about doing that, but then i felt the back flat round part (with all the text) and noticed it was pretty damn hot. if you tried to do you that you will probably melt the padding and possibly fry your pump. if heard if it is mounted correctly there is very little noise. I'm working on my new case so when thats done i'll mount the pump better, and see if this myth is true. Anyways good luck, and keep us updated on what you do and your success.
