A pair of the UPGRADED Copper Heatsinks for HP Machines.

The standard ones are Aluminium only and these Copper ones are a good upgrade from them.

Part numbers are 662522-001 and also 654592-001.

As long as one of these part numbers matches, the item will fit your machine.

These heatsinks are necessary for the  130 Watt & above more powerful CPU's but are still worth it for thrower powered CPU's as Copper heatsinks always give superior cooling.
