Copper Heat Sink & Thermal Pad for Steam Deck M.2 2230 SSD

Copper Heat Sink with Thermal Silicone Pad for Steam Deck M.2 2230 SSD

Keep your Steam Deck running cool and performing at its best with this precision-engineered red copper heat sink. Designed specifically for the M.2 2230 SSD slot in the Steam Deck, this compact radiator features an antioxidant-treated copper surface paired with a high-performance 5W/m.K thermal silicone pad to maximize heat dissipation and extend your SSD's lifespan.

Why Choose This Heat Sink?

• Premium Red Copper Construction: Made from high-purity red copper with a thermal conductivity of 401 W/(m·K) — far superior to standard aluminum alternatives. Chemically polished and milled to remove burrs, preventing short circuits and ensuring a flush, secure fit.
• Antioxidant Surface Treatment: Multi-stage grinding and oxidation-resistance processing means the surface won't rust, darken, or corrode over time — and it resists fingerprints too.
• High-Performance Thermal Interface: Bundled 5W/m·K thermal conductive silicone pads are soft, resilient, and form a tight bond with SSD particles, eliminating air gaps and ensuring rapid, consistent thermal transfer to the heat sink fins.
• Precision-Sized for M.2 2230: Measures approximately 26 × 23 mm (1.02 × 0.90 in) — precisely calculated to fit the compact M.2 2230 footprint inside the Steam Deck without installation deviation or risk of short circuits.
• Complete Installation Kit Included: Everything you need is in the box — no extra tools required.

Step-by-Step Installation Guide

1. Power down your Steam Deck and disconnect all cables.
2. Remove the 8 rear screws (four 9.5mm + four 5.8mm) using a Phillips screwdriver and keep them safe.
3. Pry open the rear cover by inserting the lifting blade along the right-grip seam and gently releasing the clips.
4. Remove the protective plate by unscrewing three screws (one 3.4mm + two 3.7mm).
5. Remove the existing SSD by unscrewing its retaining screw and carefully pulling it from the slot.
6. Apply the heat sink: Peel the protective film from both the thermal pad and heat sink. Press the pad onto the SSD chip surface, align the copper heat sink, and press it firmly into place.
7. Reinstall the SSD with heat sink into the M.2 slot and tighten the securing screw.
8. Reattach the protective cover, align it to the screw holes, and replace all three screws.
9. Clip the rear cover back onto the body and reinstall all 8 rear screws. You're done!

Note: Due to monitor and lighting variations, the product color may differ slightly from images. Please allow ±1–2 cm measurement tolerance.

Frequently Asked Questions

Q: Is this copper heat sink compatible with the Steam Deck M.2 2230 SSD slot?

A: Yes, this heat sink is specifically designed for the M.2 2230 form factor used in the Steam Deck. Its dimensions (~26 × 23 mm) and included thermal pads are sized to fit precisely within the compact installation space of the Steam Deck's SSD bay without causing interference or short circuits.

Q: Do I need any additional tools or materials to install this heat sink?

A: No additional purchases are required. The kit includes a screwdriver, pry bar, lifting blade, thermal silicone pads, M2 screws, and backup shell screws — everything needed for a complete installation on your Steam Deck.

Q: Will the copper surface tarnish or oxidize over time?

A: No. The heat sink undergoes a multi-stage grinding and oxidation-resistance surface treatment, ensuring it will not rust, darken, or corrode with long-term use, maintaining both performance and appearance over time.

Q: What is the thermal conductivity of the included silicone pad?

A: The bundled thermal conductive silicone pad is rated at 5 W/(m·K), offering high-performance heat transfer between the SSD chips and the copper heat sink to ensure efficient thermal management for your drive.
