XSPC X2O Delta CPU waterblock

Pressure Drop

Determining pressure drop for water-cooling components is really quite easy and should give the prospective purchaser some idea of how well or how badly a particular component restricts/resists the natural flow of a pump. This is especially important when designing your water-cooling loop to ensure that your pump flow doesn't come to a crawl because of your cpu block, gpu block and possibly chipset block. Factor into the equation a reservoir, various curves and connectors and the amount of pressure drop can become an issue. Hence the reason why we need to assess for pressure drop.

You can see from the above graph that although the D-TEK Fuzion provides less resistance to the pump's presure, the XSPC X2O Delta didn't trail far behind it. The reson why this has happened could probably be best explained by the fact that the D-TEK Fuzion has many special channels moulded into its copper base which essentially divert the coolant through the path of least resistance. The X2O Delta on the other hand simply dumps the coolant into the waterblock, which it then has to fight its way through all those densely packed copper pins on the way to the outlet. The end result is a loss in pressure.

Simulated Water-cooling loop

On the previous page I promised to show you the idle and load temperatures of the heatsink that Intel supply with their Core 2 Quad processors, merely to illustrate the efficiency of water-cooling. So here they are:

Intel Stock heatsink

In all honesty, it's only just a heatsink. Having the Q6600 at idle allowed for perfectly acceptable temperatures, but loading all four cores delivered abysmal results. Now on the testing summary on the previous page I mentioned that I was going to test the waterblocks at various pump speeds to see if there was any noticable difference to temperatures with less/more flow. After an exhaustive process I am pleased to announce that the results were so rediculously small that I shan't be including the temperature variations here. Let's see how the XSPC X20 Delta handled the increased heat-load of a quad-core...

You will notice that Core #2 remained consistantly cooler throughout the testing phase, and this was refected during the entire test. I re-mounted the XSPC X2O Delta and D-TEK FuZion waterblocks numerous amounts of times to ensure that it was sitting 'flush' with the Q6600's IHS, and every time, the result was always the same.

I also performed some quick and dirty overclocking on the Q6600 to see how far the temperatures could be pushed. The results you can see below:

The XSPC X2O Delta handled the extra heat from the Intel Q6600 very well and in fact, given the opportunity for a larger radiator the results could well have improved somewhat. Now let's head over the page to see how the D-Tek FuZion handles the heat...

We take XSPC's latest CPU waterblock and pit it against the D-TEK FuZion. Take a look at the review and the results may surprise you.

Excellent review there PV,

I've been waiting nervously for this cos I'd already plumped for the FuZion

I'm now very happy I did with my hotter running B3

Thanks Uncle_Fluffy for the feedback. The X2O Delta is still a very nice block and more than capable of cooling your quad-core. But you'll enjoy your D-TEK too

Nice review as ever Pvs.

nice review Matt, i would not be surprised if this block would out preform the fusion when the 8 and 16 cores come out. kind of like the storm and fusion today.

Hi ai_01 and Ham...thanks for the feedback. Your comment certainly holds some weight as XSPC are working on a new revision of the Delta as we speak. As I find out more details I'll let you know...

Superb review mate.

Having just ordered the fuZion I was especially pleased (as was Fluffy) when the comparison between the two concluded with the fuZion retaining the cooling crown.

This talk of revising the Delta has me worried!

Must... Have... Best...

Thanks mate Yeah XSPC want to beat the FuZion for sure so it'll pay to keep an eye out in the near future, and with the next revision they may well do it.

Tip top review there mate, well done. I'm happy with my Apogee for the moment though

I would have though that the block not coming with barbs would have been seen as a con in the conclusion.

Nice review othwerwise though.

The block does normally come with barbs but due to the supplier being exceptionally busy I was cutting him some slack. If you order the Delta it will come with barbs, hence the reason that I didn't include it as a con. Thanks for the feedback anyway mate

Nice review, this may be the CPU block I will use for my WC setup

Thank you. The X20 Delta is a very capable waterblock and as an added bonus you get to save some money along the way.

Aye this is a lovely waterblock, been in my loop since dayone, lovely
