First things first I have an XSPC dual pump res. using 2X MCP355 pumps along with the spec's listed below.

System Spec's:
AMD 955BE Phenom II
MSI 790FX-GD70 M/B
8GB 1600MHz Corsair
4X4890 XFX
Coolmaster ATCS 840

Other Parts:

1X ex-blc-569 EK Supreme Universal CPU Liquid Cooling Block - Acetal

4X ex-blc-599 EK Radeon HD4890 VGA Liquid Cooling Block - Acetal

As listed above the XSPC res. w/dual MCP355 pumps.

1X quad 120mm dual pass Koolance rad. (for the 4x4890 XFX)

1X triple 120mm dual pass Koolance rad. (for the AMD 955BE)

As for the questions:

1. Will one of these pumps be able to keep up on the 4X EK 4890 blocks with a quad rad?

2. Same as question 1 but with a Ek cpu block on a triple rad?

3. And what size tubing should be used 3/8 or 1/2?

4. As i have already purchased the listed items, is this a safe setup? If not, i would like to try and save as many items as possible or just improve the current setup by adding to or revising this setup.

Any and all opinions and suggestions are welcome.

Thanks, Crazy V

The EK block and that pump/rad is just just fine.

The same with the GPU's etc. GPU blocks are high flow, so you should be fine. Your GPU temps won't be as low as some rigs, but it's never about crazy low temps on GPU's. It's getting temps to the 60's or even low 70's and removing those friggin fans. You'll be fine with that rad.

Tubing size I have an issue with. You probably will be just fine with 3/8 ID hose, but you will lose some flow rate. With such a massive system, is there any reason you want 3/8 instead of 1/2 or 7/16 ID? If your going for performance, why lose a bit anywhere?

You should be getting at least 1.6GPM using a XSPC res. with MCP355 (DDC 3.2) with that loop.

All your parts will have 1/2" barbs by default, including the XSPC res., so you'll naturally go with 1/2" ID tubing.

A DDC3.2 aka 355 and the XSPC top is better than the D5 vario, tested by Martin. That said, either pump is plenty. Again, the GPU's aren't crazy particular about insane low temps.

The XSPC res is NOT 1/2 barbs. You have to buy the barbs in the size you want.

Yeah I see the data now. XSPC res. DDC 3.2 is clearly better as you've stated.

Oh, didn't knew that. Thanks.
But rest of the components should come with 1/2" barbs by default.

They might, but many resellers sell parts with options for barbs. Have to be careful. In the US, 1/2 barbs is most common. In EU, 3/8 ID or umm 8mm is very common.

Reply to Conumdrum

More than likely will go with 1/2 or 7/16. Was never fond of using the 3/8. Had a lot of flow issues in the last setup till i upgraded to 1/2.
