In the past, many people argued that adding a chipset block provides no significant improvement, but only adds heat and reduces the flow of the coolant in the current loop. Danger Den may have changed that with the MPC series of chipset waterblocks. The temperatures of the CPU did not change at all by adding the chipset block, and the design of the two blocks allows such high flow rates that the flow rate is still pretty good. According to Martins Flow Rate Estimator (a popular source for flow rate testing), the flow rate of the loop should still be above 1.73 GPM (which is considered "great" according to Martin's testing), thanks mostly to the excellent flow rate of the MC-TDX CPU block. And with some chipsets allowing voltage increases in the range of 40% or more, extra cooling will always help improve stability.

I found that the craftsmanship and the design on the MPC-975X chipset waterblock were excellent, as one would expect from Danger Den, and the base on this block has to be the single flattest base I have seen to this date. One problem I had with the MPC series is that some exposed chipset cores may be better off with a foam pad to help protect them from getting chipped, but a pad was not included with this block, leaving the small extra cost on the consumer. The other issue was something that is typical of Danger Den and some other manufacturer's waterblocks, and that is that these chipset blocks are specialized in nature and may not always be transferred from one motherboard to another. However, Danger Den does sell different tops, which can be used to match the block to a new motherboard.

Overall I was pleased with the MPC-975X chipset block and would suggest picking one up, especially if you plan on using the Danger Den MC-TDX CPU waterblock for some serious overclocking on the i975X platform.
