I'm at the point where i'm happy with my set up (e8400) and i've had my fun with air cooling in the past, now i'm looking at WC, i have a few questions though if somebody could help me...

1) what is (if any apart from size) the advantages of 1/2" ID hose compaired to smaller ID hoses (such as 3/8" or 8mm)?

2) anybody got any opinions on this set up...

Pump/Res - http://www.watercoolinguk.co.uk/catalog/product_info.php?cPath=77_87&products_id=697

CPU block (775) - http://www.watercoolinguk.co.uk/catalog/product_info.php?cPath=27_28&products_id=727

Radiator (will only be a 1x120)- http://www.watercoolinguk.co.uk/catalog/product_info.php?cPath=37_71&products_id=462

Fittings x8 - http://www.watercoolinguk.co.uk/catalog/product_info.php?cPath=39_65&products_id=975

Hose 2m - http://www.watercoolinguk.co.uk/catalog/product_info.php?cPath=38_89&products_id=660

Fluid - http://www.watercoolinguk.co.uk/catalog/product_info.php?cPath=34_96&products_id=440

then to add to that when they are available, a 4870/4870x2 GPU full block (hence the 8 fittings and not 6, for future upgrade)

3) the GPU block will probably be XSCP or EK... which would be a better choice, or are there any other brands to look for (wanting 1 with acrylic top on it)?

Cheers! :sarcastic:

Looks pretty good...I don't know much about the pump/res and have never used an integrated setup. 750l @ 1.5m head is pretty decent, though.

As for 3/8 or 1/2, it' won't make a huge difference; either way will be fine. Just go with one size or the other on all your fittings so you don't have to use different tubing sizes and screw up your flow rate.

For your radiator, you might consider (should consider) at least a 2x120mm just because you are cooling your GPU block as well. A general rule of thumb is a 1x120 per component being cooled...NB/SB excluded as well as MOSFETs.

So, CPU and GPU would mean a 2x120, adding another GPU would likely need an additional 1x120. Note: you don't have to have a single rad (1x120, 2x120, 3x120, etc), just the equivalent surface area if you want appropriate cooling. Again, general rule of thumb, may not fit everyone's case and/or budget.

Consider a t-line if you need to add coolant; it makes your life much easier to fill and bleed. You can keep a resevoir, but a t-line just before the pump is easy to feed as you fill the lines.

The pump is....serviceable I suppose. It's nto very strong when compared to more widely used pumps like the Swiftech models MCP655 or 355 (both have head of almost 11 feet which is more than twice the pump you indicated above).

An advantage that larger ID tubing (like 1/2 ID) is that, throughout any cooling loop, there are going to be points that will hinder flowrate more than others - like rads or fullbody GPU waterblocks). The larger ID tubing is more "forgiving" in that it allows you to have higher flow characteristics to compensate for the various points along the loops path that cause the flowrate to degrade. If you are going to use the fullbody waterblocks on yoru GPU than you'll want a better pump, especially if you ever add a second GPU to the equation.

I'm with rubix in that you need to allocate for a larger rad - at the very least, a 2 * 120. However, consider this, in your loop, if you have the CPU first and then the GPU (or vice versa) the second block is goign to be made to suffer from it's own heat AND the heat of the previous block as well. It doesn't matter if you have a 6* 120 rad, someone is going to suffer. If you do any o'clocking AND you intend on adding a second GPU waterblock to the loop than you might consider a second rad in a configuration like:

reservoir - pump - cpu - rad - gpu(1) gpu(2) - rad - back to resertvoir.

In that configuration, the two primary parts are each seperated by rads to cool the liquid. I hope you get the picture.

Now, as for the CPU waterblock you've chosen, it is functional. But, if you can afford it, the two best blocks you'll find on that site are going to be the EK Supreme or the D-Tek Fuzion.
