Even though the Seidon 240M looks like it is a huge pain to be installed, it actually is not; as long as you have a case roomy enough. The first step is to place the backplate behind the motherboard. Cooler Master provides an Intel backplate which can be adjusted to fit any current Intel desktop CPU socket. The AMD backplate fits all current AMD desktop CPU sockets as well.
Once the backplate is in place, it needs to be secured with the thick nuts. The nuts have a black insulation ring on one side and the user needs to make sure that it will be the side facing the motherboard! Cooler Master provides a cap, which can be seen placed at the bottom nut of the above picture, in order for the user to tighten the nuts using a screwdriver.
Once the nuts are installed, it is time to prepare the block. There are two sets of retention brackets, one for Intel CPUs and one for AMD CPUs. The appropriate set of brackets needs to be installed on the water block assembly by using four small screws.
After the water block is prepared, installation is finalized by firmly screwing it down to the CPU, after placing a thin film of thermal compound on it of course. The fans can then be installed on the either side of the radiator, depending on the user’s preference and the size of the case. Aesthetically, it certainly gives a very different feeling than tower CPU coolers and it will also leave all RAM slots entirely unblocked, for the user to install RAM modules of any height.
