Hm, I have my fans at 900 RPM, so that I can´t hear my fans at all, so I´ll here only the pump.

If I adjust the speed, the higher I go the sound gets more of a high buzzing "sssrrrrrrrrrr" and if I turn down the speed it gets more like a deep humming "brrrrr".

But the noise level is more or less the same.

Sorry for highjacking the thread like this.

Thanks again for all of your answers, I´ll put something under the pump to buffer the vibrations and will give it a bit more to bleed out completely.

The next step would be to skip out on the drainport, cause like I said before I´ll suspect it to suck a little bit of air in some way

Edit: After sitting next to it for a while now, it definitely got better now that I dislodged the pump from the mounting bracket.

Still a constant deep rumbling sound from the pump "brrrrrrrrrr"

So the tone of the sound is changing, but not the volume of the sound, correct?

And for what it's worth, I only run D5's, and I can't hear any of them!!! But I also only run the Alphacool branded ones personally.

If I test the resistance on the molex, I think that´s what you mean by OHMS, how do I read the results, what am I looking for?

When you put both leads from volt meter to both pins on molex as long as you get a number you are good. If it reads 0 then game over. Also check how many amps the motor is drawing. Check what it is rated for under full load and then put pump under full load and see what you get and compare. Lower or higher amps also means windings are failing not getting enough voltage etc...

should really make a video, we will be able to judge the sound much easier that way.

I also have a D5 but its a newer model as it is a PWN version.

It is super quiet even when Im pushing 4.5GHz

Also after reading your other posts it just sounds like the pump is just vibrating off the case. You could try some rubber washers to help with that.

Yeah correct, only the tone is changing

I´ll try tomorrow, but I really don´t now if the mic of my phone is good enough

The vibrations made it worse but the pump is not quiet at all, even if I´m lifting it up completely its a deep rumbling sound, like an engine for example

Will try to put a buffer under it tomorrow.

For a second there you got me believing that i had some special stuff for my loop frown.gif

Regarding the vibration, here is my fix for that;

Well I've just finished installing the cooling in mine and I'm pretty happy with it.

The CPU is cooled by the black loop - black tubing with Mayhems Pure Black liquid.
The GPU's are cooled by the white loop - This is clear tubing with Mayhems Ice White liquid.

Apologies for the poor pics, late at night, terrible lighting and a crap photographer. I'm contemplating adding some interior lighting now and spraying the ram covers white.

One things for sure, after this build, it will be a while before I do any upgrading!

Now I´ll have to look for something to put underneath it,

I still ahve all the packing materials. Thanks for the tip. I´m going to figure that one out tomorrow.

Nonetheless, the pump seems a bit too loud for me. Are there any highquality videos of a D5 running to compare the noise?
