EK-Supremacy MX is a reduced cost variant of EK-Supremacy EVO flagship performance water block, introduced in 2014. It has been designed to lower the production costs yet still offer premium hydraulic- and thermal performance at the best price.EK-Supremacy MX is a reduced cost CPU water block that fits all modern Intel LGA-115x and LGA-2011(-3) socket motherboards and comes with pre-assembled, error-preventing mounting mechanism. The result is a perfect installation which results in optimal performance every time.The key features are:ultra-high thermal performance - only slightly simplied copper base allows EK-Supremacy MX to achieve almost the same cooling potential as EK-Supremacy MX.very high-flow design - low hydraulic restricion allows this product to be used in setups using weaker water pumps.pre-assembled mounting mechanism - blazing fast installation, especially on Intel® LGA-2011(-3) platform.CPU socket compatibility:Intel LGA-1150/1155/1156Intel LGA-2011(-3)Enclosed:EK-Supremacy MX series water block with pre-installed mounting mechanismEK-Supremacy MX Backplate (for Intel LGA-115x platforms)TIM / thermal grease: EK-TIM Ectotherm (1g)Torx key T20PLEASE NOTE:Narrow server type LGA-2011 is not supported by default – a Mounting plate Supremacy LGA-2011 Narrow ILM is mandatory to install this water block on narrow server type LGA-2011 motherboards.EK-Supremacy MX Backplate is to be used only with Intel LGA-115x type motherboards.EK-Supremacy MX is not compatible with LGA-2011-3 motherboards that do not have mounting holes through the circuit board (e.g. some ASRock and Gigabyte motherboards). The problem can be remedied by purchasing separate EK-Supremacy EVO PreciseMount mounting mechanism.
