XSPC X2O Delta CPU waterblock
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.
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:
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...
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:
