D5 vs DDC 3.2, and pump speed control

They seem to have similar performance. Both of them are the same price if you buy the pump alone, but D5 is more expensive in a bundle.

What is the difference between these two, and will I be able to slow down the DDC by using a high power fan controller?

Thanks in advance.

Edit: I'm planning on getting a Koolance 380, a Enzotech 81 MOSFET block, twin 3*3 rads, and perhaps a GPU block if I upgrade my GPU (not gonna happen anytime soon).

Might want to look this over ... http://martinsliquidlab.org/pump-planning-guide/

Get a standalone D5 with a koolance top - benching shows they are the quietest. Get a separate rez and get the speed controlled version of the D5 it will cost less than a controller.

Yuck bay res... It's not what you're asking but I'd be remiss in my duty by not telling you to look at getting a 35x and optional res or other tube res. Btw, 35x has pwm control so you get fancy pwm control heh.

Thanks for the inputs, but is there any direct comparison test between the DDC 3.2 and the D5?

This is the newer DDC 3.25 with a Koolance top vs a D5 which is pretty close:

The older DDC3.2 is very similar..has a touch more head pressure below 1GPM and more above. The DDC with top will generally produce more flow than a D5, but the D5s are quieter. Each has it's own advantages, but if you are really sensitive to noise, then get a D5 and DO NOT get a bay reservoir....stand alone and decoupled from the case.

Pretty much this.

I mainly use D5 pumps, both single and dual.

I have 3 rigs that use single D5. 1 with a bay res, 2 with a cylinder res.
I also have 2 rigs that use dual D5's. 1 with a bay res, 1 with a cylinder res.

You can get a bay res to be very quiet, but you really have to make sure you secure it with the rubber gaskets, or at least make sure it doesn't hit any of the edges of your case. Generally, they are more of a pain to make quiet, but it can be done.

The cylinder reservoirs are by far my favorite. Since they are decoupled, it is very easy to make them quiet. I think they look better. But in a lot of cases, it is just easier to mount a bay res.

The other nice thing about D5's over DDC's ... the D5 is cooled by the water that it pushes. With DDC's, they are cooled by air, and in some cases, you might want to go with an after market heat sink on them.
