Small square aluminum heatsink with vertical fins and mounting holes

Graviton

Graviton Motherboard Chipset Heatsink 40×40×30 mm 59 mm hole distance

SKU CH-8XH1-SGM77

Aluminium heatsink cools North-South Bridge chips with 40×40×30 mm fins and 59 mm mounting holes

  • Cools North-South Bridge chips with 40×40×30 mm aluminium block
  • 59 mm hole spacing fits many motherboard mounting patterns
  • Extruded aluminium construction transfers heat away from chipset
  • Compact 30 mm height clears low-profile expansion cards
  • Single-piece design installs without separate brackets or clips

Purpose and Fit

This aluminum heatsink targets motherboard North-South Bridge chips needing passive cooling. Builders replacing a missing or damaged factory sink on boards with a 59 mm mounting pattern will find it a direct fit. It is not suited for CPU sockets, GPU memory or voltage-regulator arrays that demand larger surface area or different hole spacing.

Capacity and Headroom

The 40×40×30 mm fin stack dissipates heat from typical chipset components under normal desktop loads. Under sustained heavy chipset activity — such as high-speed storage arrays or multi-GPU configurations — the small mass and limited fin count can saturate, letting temperatures climb above comfort margins.

Deciding Specification

Mounting holes are spaced 59 mm centre-to-centre; verify the motherboard matches this dimension before purchase. The sink ships as a single piece with no thermal pad or adhesive included, so a separate interface material is required.
