A PC’s MOSFET chips are among the smallest PC components that generate enough heat to need added cooling. MOSFET heatsinks are sized accordingly, some being just under 7mm square. Despite their size, MOSFETS generate a lot of heat, and good heatsinks can provide more stable performance from them. TITAN RIG stocks copper heatsinks for your MOSFETS, sized for the job. Be sure when looking for them that they are sized correctly for your needs.
