Is the D5 really quieter than a DDC?

I have both pumps though have only ever used the DDC in my loop.


I am thinking of going to an alphacool tube res-top for either pump.

Obviously the D5 takes up a bit more room but would consider it if it's quieter overall.
 
Thank you gents.
I prefer the look of the Alphacool Eisbecher D5 version it's meatier too. I just have a boggo standard D5 but at least their speed is variable. My DDC is currently on 12V and bless it does emit some noise.

Thanks for the input time to retire my faithful DDC.
 
Can you not tone the DDC down? I have a EK DDC 12v (but PWM) and at lower RPM's is just as quiet as my D5's at lower RPM's. Just whines somewhat when I notch up the RPM and D5 is quieter at higher RPM's.
 
I have the Maximus Hero X coming which has a high current (3A) pump header but as my DDC is not PWM i'm not sure you it will work though did read it can be for pure DC control too?

After my aquero system failed to start my pump twice (on one occasion frying two GPUs!) I now believe in pumps being 'hard-wired' into the PSU hence my interest in using the D5 which just has a simple Molex connector on the end!
 
I own both pumps and i believe its how you set the pumps and the pump tops itself. mine runs quiter than my d5 did and i am running dual ddcs, although mine are pwm

As for your aquero fail, im sorry to hear that, but really speaking from the amount of happy people i know who use them including on these forums/and the aqua computer forums and other forums, your case is quite unique and rare. i wont just point the finger and ask why you did not ask for helps in setting up an alarm which you can do in the software,and still would have worked regardless of you not being able to load the system(if you used an aquero computer) as all settings are saved to the device. i know this to be true because like an idiot when i first built my pc with aqua computer i couldn't be bothered to sort the cables at the back of the case so when i put the back case back on it had crushed the cables and thus the pumps was nto working. temps crapt up then a shrilling alarm went of on my aqua computer. the system does work. perhaps you did not set it up or understand what you had ?

If i am wrong i appologise
 
I had no alarm setup but end of the day it didn't power my pump on twice would you trust it again if it were you?
Why am I now going to risk my new 8600k and GTX 1080 to such a system.
Their software was broken from day one and now they want me to pay to continue using it/upgrade no thanks all it's good for is showing the rough temp of my water and controlling my fans.

The software i would admit is pitta to setup first time, not much around to help, all though there is a lot now, if you think its just for the above, clearly you did not understand quite what you was buying into. it is not just a basic fan controller, it is a very advanced computer.it has unparalleled configurations.

And yes i would still use it, i would look into he reason why if indeed it did fail. the aqua computer hardware is not cheap so jsut throwing it away is a compleat waste.

As for buying the software. no you dont have to buy it, although i did for a small charge. you just miss/loose the new features such as web, i t works perfectly fine without updating them.

If you want to change your mind about the aquaro just pop into the offical thread i see you posted in, there are plently of people who will help you including aqua computer themselves. there customer services are very good btw
 
I'm butt hurt sure but I had over £500 of gpus melt on me because of it. I just won't use their products again for imprtant things
 
Quite simply, in terms of noise/performance DDC pumps suck **** in comparison to a D5 pump.

My advice is never buy a DDC unless you absolutely have to (you don't have enough space to make a D5 fit)

PWM is terrible compared to a good old fashioned molex fan connector/fan controller set to fixed voltage.
 
Sorry to jump into someone elses thread but going by the posts in here from D5 users the D5 doesn't hum as it is working? My old Aquaextreme 50z pumps while still doing a sterling job have a annoying hum to them and it's the loudest sound from my system by far. If I swapped to a D5 with a decent top would I or wouldn't I still hear a humming noise?
 
I used to have a dual loop system with a D5 and a DDC, at low RPM as said above you can't really tell the difference. I wouldnt use anything else apart from a D5 now as they're pretty much bullet proof.
 
Before I tried using a DDC (started using a D5) I didn’t think for a second it would be enough to bother me, nor would I hear it over the fans I had running.

Unfortunately that wasn’t the case - the difference between the two is huge.

The D5 at full speed is completely inaudible while the DDC, as Jokester said, produces a horrible electrical whirring/whine even at low RPM. I bought the PWM version and while it does help, the pump runs at full pelt on PC boot and sounds absolutely horrible :(
 
not had a ddc but the d5 on setting 3 inside a case cannot be heard over the sound of the 5 140mm radiator fans running at 5-600rpm

I need to finally upgrade my pump then. Had my trusty 50z's since I started watercooling some 12 or so years ago.

You need the newer Aquacomputer pump, as I know you have a Aquaero already, hooked up the two work well together, at low Rpm its pretty much silent.

I had a D5 before and found that its "Hum" just used to pass right through the sound dampening and make the whole case act as a tuning fork, with zero fans in cold weather with the external water cooling the "hum" drove me mad!
