There's also a solar panel optimized version which is distinct in that it has very low starting voltages and is hilariously expensive :lol:
However, as far as I'm aware, the mechanical internals are quite the same (the solar version maybe has a slightly adjusted electric motor, idk), it's just the electronic control elements that are different.
I once read somewhere that all Laing pumps are made by Delphi anyway (as are the EKWB and Phobya pumps and all those that look the same), and from time to time you will stumble on a Laing pump listed as Delphi, so basically all you need to know if you need a vario or a non-vario, with or without tach signal, 3 pin or PWM. The rest is just different stickers (aside from the Aquacomputer Aquabus version).

Cheers guys . With the tacho signal, how does that work exactly ? Plug into motherboard header, and you can get the pump speed ?
It looks like i'm going to go for the Koolance PMP 500, smaller than the D5 more power, but around 2 - 4 decibels louder . But there is no need for a top , and it has a built in heatsink. Dam sexy looking to.

Pretty much, a M/B fan header or a fan controller (such as a Lamptron) that can read the tach signal.
The Aquacomputer D5 (the normal one, without Aquabus interface) has a 4 pin molex for powering the pump and an additional 3 pin fan header to which only the tach cable is hooked up. So you can plug the pump into the PSU directly and deliver the tach signal to your M/B or whatever have you.
I'm not sure how this is with other brands, but I actually have the AC one.
The new Swiftech D5 runs of PWM so you would plug the power cable into your PSU and the control wire into your motherboard/fan controller and it will allow you to vary the speed. How much use that would be is up to you, but it looks like a promising development for those of us who like to quieten down our systems as much as possible.

I cut the tacho wire off mine.
If you've got the vario, there's really no need for it IMO

Well, need is a very relative term when it comes to water cooling anyway imho :lol:

If the pump's power is connected to the PSU, and the tacho wire connects to your motherboard, I can't see how the flow of the pump can be adjusted? Unless this is a newer model I've not seen (did a quick search and couldn't find anything).
I thought the aquacomputer version was the only one that had flow control (via aquabus) instead of the red potentiometer on the back of the pump.
I take it back mate, turns out Swiftech do have a controllable D5 pump! The MCP 655-PWM Drive version:
