How loud is the MCP35X supposed to be?

[Mabyboi]

I just picked up an MCR320-Drive R2 Rad/Pump/Res and its running great so far. My question is how loud is the pump supposed to be? Theres an audible vibration/whine coming from it and im wondering if thats normal or not... if it is how do I silence it?

Thanks guys!

How do you have it mounted? I have mine rubber isolated otherwise the case picks up and amplifies the pump noise.

Its mounted vertically like so:

I have the first 320 MCR pump/rad setup with the original pump before your model came out. My 320 is set up vertically outside my case using a rad box. The pump is not in contact with anything and it's silent.

The only time I hear noise from the earlier pump is when it's in contact with something. It's hard to see from your picture if the pump is contacting your case. Sounds like there is some contact. Either try keeping the pump free of contact with the case or isolate the pump bottom with some of the gel pads that are available.

I just isolated it on a gel pad and its not really lodged into the case anymore... but now its louder and there seems to be A LOT of air passing through... heres what it sounds like recorded from my iphone from about a foot away.. http://soundcloud.com/akdmcdonald/pump-8/s-9ZkzV

have you considered that the radiator itself is acting like a resonant pad? vibrations transfer from the pump to all the surface area of the radiator.

consider a form of softmount inside the case to help dampen this vibration. as far as which type of softmount will work best, that is up to trial and error. different materials dampen different frequencies.

Hate to point out the obvious but if you hear air then its clearly not fully bled. Get rid of the air and Ill bet you get a lot less noise.

My current 320 is my second rad/res combo radiator. For me, I love it. What I have found out using this combo, is that it is best to fill it & bleed the air with the system outside of the case, with the blocks at the lowest point. I also cap the rad and move the blocks around to ensure all air is out. Makes for very good leak detection / hose tightness check.

In my setup, with the rad on the back of the case, I thread the blocks back into the case through the second PSU hole in my case. My case is an older Stacker.

Looking at your setup, it looks like you can pull the rad & connected block / graphics card out, bleed the system, then reinstall inside the case. I bled my current setup with the graphic card attached to the graphics cooling block.
