Single or Double pass?

[enz660]

I will be building a watercooling system with a gpu and cpu block. I was told that this will need a high pressure pump, I think the mcp350 pump will do well for this. I found a black ice triple core radiator, it comes in two versions, single pass and double pass. Which one is better for my system?

Search button please.

EDIT: This has been heavily discussed in the past, some of the huge threads might be helpful to you.

probably the single pass. cause you want to get maximum flow considering you have gotten a lower head pump.

[Arca_ex]

MCP350 is not a lower head pump, unless you consider a D5 a lower head pump too...

Double Pass

[Rickster]

MCP350 as compared to MCP655 has lower head pressure. but you can mod the top of the MCP350 to get more head pressure

[Deathknight]

The MCP350 top mod will reduce head, not increase it. This mod increases flow.

[Rickster]

so deathknight, what is your suggestion for enz660 then?

[soulfly1448]

Buy an Eheim 1250.

Um, the mcp350 has MORE head then the mcp655 (d5). It's lower flow though. When you mod the mcp350, the head actually drops a little but you get a lot more flow out of it. The MCP355 moded should even beet the MCP655 at all flow points (except max free flow, maybe).

I'd say it depends on your loop. If you can route tubes better with single-pass, then go with that. If you can route better with double-pass, stick with that ;)

From the research i've done, most people have said the difference isn't that great between them. Most say to just use whichever one will make your loop shortest.

Single pass will help you squeeze out that last bit of perfomance because it simply eliminates !some! of the pressuredrop from the rad. But rad size and density decisions will have a far greater effect on the performance of your loop.

senater is your sig correct? A mobile barton running at 2873 mghz!221 x 13 = 2873 Impressive if not a mistype. sorry for the small thread crap guys.:beer:

single vs double... it doesnt matter. temp will be within 1 degree of eachother...

I agree on the "using the search button" first for this thread as this topic really has been covered over and over again with some very detailed discussions on the pros of one vs the other.
