The Shadow Rock LP is a 75mm tall low profile heatsink rated for heat loads up to 130W TDP. It's built around four 6mm diameter copper heatpipes and relies on a single 120x120x25mm "PureWings 2" fan operating at 1500RPM (51CFM at 1.25mm/H2O according to manufacturer specs) to move air through a 22mm thick, horizontal nickel plated aluminum fin stack. The large fan gives the Shadow Rock LP an effective footprint of 122x136mm, with the solid copper heatspreader located asymmetrically to one side.
