are these practically the same type of pump

Laing D5 / Swiftech MCP650/655


which one is better?

 

[aigomorla]

the 650 is also known as the D4.

The D5 and the 655 are the same pump.

Not sure, but I found this thread discussing differences between the "650" and "655".

 

[bleucharm28]

ok, so D5 and MCP /650 655 is the same type of design. Man this is some confusing stuff.

 

[aigomorla]

the D4 is the blue body aka the 650.

was replaced by the more powerful and also a lot quieter 655 known as the D5.

Get a 655 or a D5.
Dont get a 650 or a D4.

To be a little bit more precise, the MCP655 is a Laing D5. Laing is the original manufacturer, and Swiftech just re-brands them.

Other companies do also:

Koolance's D5: http://www.koolance.com/water-cooling/product_info.php?product_id=493
Danger Den's: http://www.dangerden.com/store/dd12v-d5_pump-variable-speed-by-laing.html?&cat=23
EK's: http://www.ekwaterblocks.com/shop/pumps-and-accessories/pumps/laing-d5-pump-12v-mcp-655.html

...they are all the same pump manufactured by Laing. The main differences you will see are that some have a knob that allows you to adjust the speed (1-5), this is the D5 "vario" (Swiftech MCP655); and one that is set to speed 4 permanently with no knob, this is the plain D5 (Swiftech MCP655-B).

...It's actually easiest just refer to them as "D5" all the time, and maybe "D5-vario" if the speed adjustment is relevant to the conversation. Everyone will know what you're talking about if you refer to it as a "D5".

 

[bleucharm28]

mmk, kewl guys. That definitely clear things up a bit.

 

[Gillbot]

There are also two models of the 655. MCP655 has adjustable speed of 1 (low) to 5 (high), the MCP655-B or "Basic" is fixed speed at around a level "4" of the regular MCP655.

more questions.

The radiator of my choice is:

My question is should i be using slower fan? and yes i would like it quite, and keeping my cpu/nb/sb nice and cool.

 

[Meghan54]

Just curious why that particular radiator? While the most expensive solution for the size, it's not better performing at all.

I'd really look at the EK Coolstream or the XSPC RX....both perform at least as well as the TFC at a much lower cost, esp. the XSPC.

No. There are two basic types of Laing pumps commonly in usage, the D5 and the DDC. Any aftermarket parts for one are not compatible with the other.

DDC:

Yes, this will work. This is a dual top though for running two D5 pumps in two loops. You can of course only use half of it to start with, and add a second pump/loop later if you want to.

My advice is to just buy a D5 without the top first, build your loop, and then see if you want to upgrade from there. This will give you a much better idea of what you want to do before you spend money on a top. I've looked at and measured my setup a dozen times now, and I'm still not sure what top/configuration I want to do next.

these are both for the DDC.

On a side note... Since you haven't bought a pump yet, now might be a good time to investigate the the pros/cons of a D5 vs. DDC pump. I don't have any experience with the DDC, so I really can't comment. However, if you look around a bit, you'll find threads about this on AT and other forums.

Here's a review of some of the most common 120.3 rads http://skinneelabs.com/triplesv2.html which includes results for different fan speeds. The 120.4 versions of these rads should perform relatively the same given they are the same construction only longer.

I'm also not sure what type of case/mounting system you have planned, but be aware that a 120.4 rad is frikken HUGE inside of a PC case. The thick TFC will be enormous. If you mount it on top, it will run from front-to-back in an E-ATX case and will take up at least two 5.25 drive bays.

Also, not all 120.4 rads are the same size... Case in point, the XSPC 120.4 won't fit in my case, but a Swiftech MCR420, TFC X-Changer 480, and Thermochill PA120.4 (15mm fan spacing revision) will.

I'm not trying to discourage you from getting a 120.4 rad, but just letting you know that you definitely need to measure and research dimensions before purchasing. Unless you are mounting externally or have a Mountain Mods case, chances are you will be working with mere millimeters to spare with a 120.4 rad.

hey guys

Thank you so much for clarification with those pump. i'm definitley going with the D5 with speed control. I did some measuring with my TJ07 caseand im sure the fesser radiator should fit. I think the gentletyphoon fans should work well. I really like http://www.frozencpu.com/products/10...namitedata.com because i'm trying keep the pump/reservoir inside the 5.25inch bays. This should give it a real clean look; i think. I just need to figure out what reservoir to go with, and i prefer something small.

This stuff gets really expensive, but i think in the end it be really worth it. The reason i bought the TJ07 was because of water cooling.

*sigh*

Why doesnt anyone listen to me...

The Laing D4 is rebranded and named the Swiftech MCP650.
IT looks like this:

You see it has a blue impeller chamber.

THe D4 is LOUD, and was quickly discontinued to the new D5.

Laing D5 is rebranded and called the Swiftech MCP655.
The D5 has a black impeller chamber like this:

The d5 comes in 2 versions, a vario and non vario.
Vario basically allows you to tune your pump speed.

The NonVario only has 1 setting of 4
The Vario has a setting of 1-5.

GAh i hate D5's to be honest.

Im currently using 5 DDC's in my system.

 

[smackababy]

aigomorla, can I inquire as to why you dislike D5s? I've only used DDC's in a system, but I currently have a D5 just waiting for my next build to be ready to water cool. It has made it as far as me opening the box to ensure it was intact.

 

[aigomorla]

There big.. ugly..

and reliability vs the new DDC's, i dont see it.

The new DDC's are fairly reliable, and there smaller, and they give better performance with an aftermarket top.

So the only advantage a D5 has is the size... you got a more durable motor tho, but that's about it.

When it comes down to it, they both have the same MTBF time, so they should be equally reliable since there from the same manufacturer.

Part of the reason I prefer the D5 is to annoy aigo.

Aside from that, the colored section you are referring to is not the impeller chamber. That is the MOTOR section. The impeller chamber is where the water is chief.

As for failure, I still think the D5 is more reliable. It has less to do with the pump though and likely more to do with the user. Since the DDC is smaller, people cram it into areas where it can't get enough airflow. Since the D5 is big and ugly, it needs more space and likely gets mounted in less cramped areas.
