Keep your critical electronics running cooler with this Easycargo VRM copper heatsink kit. Each tiny 9mm x 9mm x 4mm copper block is designed for passive cooling of the small, hot components that often get overlooked: VRMs, MOSFETs, stepper drivers, VRam regulators and laptop PC boards. Copper conducts heat far better than aluminum, so these mini coolers pull heat away from sensitive chips and help stabilize performance under load.

The kit includes 10 heatsinks, each with pre-applied thermal conductive adhesive tape on the back. That means no messy paste, no clamps and no drilling. Just peel, place and press onto a clean, flat surface. It is an easy, low-cost upgrade for DIY builders, repair technicians, 3D printer owners and anyone tuning a compact PC or single-board project.

• ✓ Copper body moves heat away from chips faster than standard aluminum sinks
• ✓ Pre-applied thermal adhesive tape makes installation tool-free and clean
• ✓ Compact 9x9x4mm size fits tight spots on dense boards and small enclosures
• ✓ 10-piece set lets you cool multiple components or keep spares on hand
• ✓ Ideal for passive cooling where a fan cannot fit or where noise must stay low

These mini heatsinks are built for passive cooling of small, high-heat components. Common uses include VRM and MOSFET cooling on motherboards and graphics cards, stepper driver cooling on 3D printer and CNC control boards, VRam regulator cooling, and general component cooling inside laptops and compact PCs.

To install, clean the chip surface, peel the protective film from the adhesive backing, align the heatsink and press firmly for a few seconds. Allow the adhesive to set before powering on.

• 10 x Easycargo VRM copper heatsinks (9mm x 9mm x 4mm)
• Pre-applied thermal conductive adhesive tape on each heatsink
