Heat Sink

To maintain maximum clock speeds (and thus performance) the electronic components need to be cooled. Our Spacer Wall design helps, but in heavily loaded cases, adding heat sinks to certain components will help even more.

Heat Sink Tape

A lot of so called "thermal adhesive tape" and heat sinks with "thermal adhesive tape" being sold on the market are NOT real thermal conductivity tape.

For example a lot of those tapes and heatsinks have "3M 9448A" printed on them, they tape is just a double sided tape - it is NOT design to transfer heat onto a heatsink.

Real 3M "Thermally Conductive Adhesive Tapes" are quite expensive and have numbers disclosing their thermal conductivity (measured in Watts per metre Kelvin e.g. most thermal bonding materials have values from 0.4W/m.K to 4W/m.K).

An alternative to thermal tape is to use Heatsink Adhesive (with minimum thermal conductivity of 0.6W/m.K) and to prevent the heatsink from falling off with a minimum breaking strength of 1.5MPa (Mega Pascal).

Heat Sink Colour

Assuming the material, shape and size are the same, if you have a choice of heat sink colours then pick Black for its abilityt o radiate heat away from the heat sink. lighter heat sink colours (e.g. silver) are normally only needed when there are external heat sources and their heat need to be reflected away.
