Watercool Your Memory: EKWB Updates RAM Water Block Lineup

EK Water Blocks has announced that it has released four new memory water blocks. The EK-RAM Monarch X2 blocks are designed to be a direct replacement for the passive heatsink installed on Corsair Dominator and Dominator GT memory modules.

EK-RAM Monarch X2 blocks are designed to cool two DIMMs at once, and they feature G1/4 threads, allowing them to be connected directly to a water cooling loop. These blocks mount directly to the top of the Dominator DIMMs using the same mounting points as the stock heatsinks. The company offers a heatsink for other memory types that allow for the EK-RAM Monarch blocks to be used with any brand.

EK has released four variants of the EK-RAM Monarch X2 blocks. They are available with clear acrylic tops or black POM Acetal, and each top can be paired with the option of an electrolytic copper base, or nickel-plated electrolytic copper base.

In addition to releasing four new blocks, EK Water Blocks has announced that six previous memory blocks have been discontinued, and the remaining lineup has undergone a name change.

The following products have been designated End Of Life. Once these are sold out, they will not be restocked.

    If your memory is running so hot that air-cooling isn't enough, you shouldn't have built your computer inside a toaster oven.

    Yeah I'm not seeing the point at all. Memory is so fast these days its almost never the bottleneck except on APU's but I just cant fathom wanting to do water cooling and using an APU vs just buying a discret CPU and GPU combo.

    I have to wonder what kind of system would push RAM so far that liquid cooling is necessary for it. I think this embodies the phrase, "more money than brains."
