DangerDen/Swiftech mag pumps... Radiator question

[megalomando]

Hi,

I'd asked this elsewhere but got no replies so perhaps someone here might have the answer.

I was wondering if there's any difference between the Swiftech MCP655 and the Dangerden DD-D5. They're obviously using the same exterior case and both have the rheostat but Swiftech mentions a new chipset controller which I didn't see on Dangerden's site.


Nother question;

I've been using a really sweet but large single pass Chevy radiator 12"x7"x2" with my Cascade and XP2600. I made a really nice manifold for it about 8" long with two slow moving fans. Cathar, the inventor of the Cascade & Storm showed me a link analyzing air flow characteristics of fans. Turns out for there to be no appreciable loss of cooling because of the hub you need a lengthy manifold (There's no air being moved by the hub so it's dead space on the radiator if the fan is close proximity to it) I needed a large manifold located outside the computer for max benefit as it wouldn't fit inside the mid-tower. To keep this computer portable I'm not going to use the separate manifold & I'll use that on my computer in my Ham Radio shack.

The distance between the fan & the radiator needs to be 3 times the diameter of the hub for the turbulence to fill in the dead air space left by the hub so I've had this mounted outside the computer in it's own separate case with the Iwaki inside the manifold to keep the pump really cool.

I'd like to mount everything inside my new computer (opty 165) this time & I bought an Antec Mid tower / 500WPS case. Here's the link to it: Antec Tower & 500W PS and I'm thinking I could remove the lower bay and put a smaller radiator inside with a smaller & less effective but probably adequate manifold.

So back to the second question... Looking at radiators I see the coolrad 12t which is shown here: Coolrad 12T is rated at 790KCal/hr

& there's this rad from Dangerden, the Black Ice X-Flow Extreme seen here: Black Ice X-Flow Extreme It's also rated at 790KCal per hour

So the question is any clue which is made better? The Black Ice is a single stage and the coolrad looks to be a 2 stage. I read single is better but with the same Kcal ratings I'm not sure if that matters.

Is there another radiator of the same size I should look at with a greater efficiency yet?



Any difference whatsoever electrically & mechanically between the DangerDen DD-D5 & the Swiftech MCP655 Pump?

Thanks for your input!

I found that helpful, compares a lot of different pumps

Nice link.

Looks like the 50Z is out of stock everywhere I've looked. I do have a Iwaki MD20-RZ which was what Cathar suggested I get back when I bought my Cascade from him. It's a marvelous pump but I'm looking for something a little more compact and will take the hit in cooling on this project.

I may use the MD20-RZ on another computer or I may sell it. It is a very sweet pump.

I'd like to find a comparable analysis of radiators like the one for the pumps. Some cores are the same size but rated differently. Question is if the #'s are using the same testing standards & if the results were altered for a sale.

Thanks for the link.

Just bought a coolrad 12T, a MCP655 12V pump and will be somehow fitting everything into my case but the radiator will be mounted to the back wall, not the front bottom blowing out.

Anyone know of someone using this configuration & how they like it?

Thanks,
