Really confused about pumps HELP

post #1 of 12
Thread Starter 
Hi, OCN

First time water cooling:

OK I would be running two 240mm rads and a cpu and 1-2 GPUs in my water cooling Rig

I can't decide what pump I should get

First I was thinking about this : http://www.jab-tech.com/Swiftech-MCP-355-12v-DC-Pump-pr-3510.html

but then I saw these : http://www.performance-pcs.com/catalog/index.php?main_page=product_info&cPath=59_201&products_id=33265 which I would get 3 of and put them in this http://www.frozencpu.com/products/9872/ex-pmp-91/XSPC_Triple_Pump_Acrylic_Top_Laing_DDC-1T1TPlus_MCP-350355_Replacement_Top.html?tl=g30c107

or this http://www.frozencpu.com/products/10038/ex-res-161/XSPC_X2O_750_Dual_525_Bay_Reservoir_Pump_-_Updated_Version.html?tl=g30c107

But I really don't know I NEED YOUR HELP !!!!!!!!!

Also I don't want to spend too much on the pump like anything over 100$ dollars is kinda a bit too much

Thanks guys

OK, so the 355 pump is a perfectly good pump.

The DCLT is a very low powered pump and the res you linked to is not made for it. It is made for the 355 type pumps and would be silly for any normal build.

The X20 pumps have been reviewed by Martin and apparently are better than they used to be, however they still don't look like something I would want to depend on.

If you want a pump either a 355 or a D5 is all you need.

There's absolutely ZERO point to getting a 355 these days when you realize that you have to buy a top to get it to work in most loops. Adding a top to a 350/355 pump raises its price to the level of a 35x or more and in that context you'd be crazy to not just buy a mcp35x outright. The 35x is superior in every way, it's the alpha dog of DDC pumps.

Ok thanks for that but doesnt a MCP 35x also require a pump top ??

Also what do you think about the other pumps

Nope, it comes with the best top made already... which is why it is the alpha dog hehe.


Hmm, there's not much worth thinking about the other pumps, well the ones you linked in your OP.

Thanks for the help,

I seen many build logs and I see these Bitspower pumps but I cant find them anywhere I think they are D5pumps anyone link please ??

Yeah you must really like the MCP 35x, its in all your builds lol

yeah seems like a good pump have been looking around and see no bad reviews of it

EDIT: yeah its eaither the MCP 35x or D5

EDIT: we are talking about this right?? just making sure http://www.jab-tech.com/Swiftech-MCP35X-12V-DC-Pump-pr-4750.html

Yea, that's the one. I like the 35x because it is one stop shopping for the best balance of flow and head pressure. This is where it differs greatly from the D5, which has very little head pressure. Even a basic DDC like the mcp350 will blow by the D5 in head pressure. The D5 has very high flow, but high flow is not very useful for our blocks because over 1.5gpm and there are diminishing returns. There's a lot written on the differences and ppl will have very different feelings between the two pumps. Oh, the one thing the D5 really excels in is low noise... er if you run it at low speed IF you have a vario, ie. variable speed one. Also, I should add it is the king of bling as pumps go with all the dress up kits and what not.

But again for me I need head pressure and flexibility and the 35x gives me that, high pressure, small size, PWM control.

Describing the D5 as having very little head is pressure is a wee bit of an exaggeration. The difference at 1 GPM flow is around 6.5 PSI VS 5 PSI.

The D5 is quieter at the same flow rates. The 355 type pumps also get quite hot when running and there have been instances of them burning out. There is a reason they sell a heatsink for it.

In the real world there will be very little difference in the results you get in a normal loop. The 355 / 35X type are great if space is an issue, the D5 type are great if noise is a priority.

Edit: The "Bitspower D5" you see in a lot of builds is just any ordinary D5 type pump (all the diff brands are made by the one company) with a bitspower modification kit. After you buy the pump and then all the bitspower pieces it starts to get very expensive.
