The quietest pump - bar none?

post #1 of 11
Thread Starter 
All,

I'm currently running an MCP-355 with an EK acetal pump top. It is a pretty quiet pump, but when I have my fans dialed all the way down,it is the loudest component. I've got 4x Noiseblocker multiframes on an RX480, and NB Blacksilent Pro case fans, all on a fan controller or PWM control. The amount of cooling I get at very, very low fan noise is pretty amazing.

The thing that's bugging me is their is a bit of a whine with this pump. It's not much, but it's there. I have it mounted on a gel pad in the bottom of my TJ, but even decoupled I can still hear a bit of a whine.



TL;DR: Will I be wasting my money to go to a variable speed D5...will it be quieter if I adjust the speed? What's the best aftermarket top/pump shell for the D5? I'd like one that will work with 1/2" compression fittings. Also to consider, my res will be directly above the pump and will have tube run to the bottom compartment of the TJ. It seems the D5 intake isn't set up ideally for that but I could always get some 90's or something. I'm not that keen on running a 35x in PWM mode, are there ANY other pumps out there that will be quieter than my 355 running full bore all the time?

Thanks for any help!

The D5 is the quietest around but have you considered putting your DDC on a fan controller and dialing it back? Cheaper than buying a new pump and top.

From what I've read the risk isn't worth the reward. I would prefer to not clutter up the look of my case as well.

Awesome, thanks. Will I have any issues feeding the pump from above and discharging to a rad parallel to to the pump in a TJ 07?

You will be okay with "feeding the pump from above". In fact, that is the way it should be. Your pump should always be right after your res and below it, hence you will be feeding it from above.

If you want your pump to accept 1/2" compression fittings, you might have to get a pump top that will allow you to do that. As that pump most often comes stock with barb fittings.

I just found it odd that the intake on a D5 is on the side and the output on the top. I will definitely get custom parts with g 1/4 threads.

can you not just turn the pump on it's side? it's what i planned on doing, and didn't think there would be an issue with that.

Thanks guys, I'm settled on the D5. Just found BP mod top that allows the in/out positions I need. +Rep incoming for you, for some reason it's not working on iOS.
