These heatpipe memory heatspreaders (HXR-5500BL) are an updated, improved version of Nexus' original memory heatspreaders. They include the addition of a heatpipe and increased heatspreader area.
These heatpipe memory coolers improve the dissipation of the heat which your memory chips are producing. Improved dissipation means less heat, which means more stable operation and less fatal errors. These Nexus memory coolers with heatpipe technology are now available in black and blue.
