Cooling Systems and Coolers: Why They're Tied to Board Revision

Why a cooler cannot be chosen "by size"

A laptop's cooling system consists of heat pipes, a heatsink, and a fan, the shape of which precisely matches the placement of the CPU and graphics chip on a specific motherboard revision. Even a visually similar cooler from a different revision might not align with the chip contact points.

Board revisions – a hidden trap

One laptop model line might have been produced with several motherboard revisions (different CPU/GPU configurations) – each revision often has its own cooler, incompatible with others.

One fan or two

Workstations and gaming models may have separate fans for the CPU and GPU – in such cases, the cooling systems and the fans themselves are selected separately, not as a single unit.

Typical customer mistakes

• "The cooler looks the same – so it will fit" – the placement of the heat pipes relative to the chips must match exactly.
• "I'll buy a more powerful fan for better cooling" – the mechanical mounting and the connector on the board must be compatible; a more powerful fan with different mounting simply won't install.

How to choose a cooling system from us

Provide the exact laptop model and, if known, the motherboard revision or the Part Number of the old cooler.
