Choosing Your Thermal Solution: Pads or Shims?

Once you confirm PCH throttling, you have two primary solutions: thermal pads or copper shims. Both improve heat transfer, but they serve different scenarios.

Thermal Pads: The Flexible Choice

Thermal pads are pliable, silicone-based materials with thermal conductivity. They are excellent for filling irregular gaps.

This helps create uniform contact between components and heatsinks. They come in various thicknesses and thermal conductivity ratings (W/mK).

Higher W/mK values mean better heat transfer.

Copper Shims: Precision Performance

Copper shims are thin, solid copper plates. They offer superior thermal conductivity compared to most pads, but require extremely precise sizing.

Shims are best used when the gap is very consistent and flat, allowing for direct metal-to-metal contact with a thin layer of thermal paste on both sides.

Measuring for Success

Accurate measurement is critical. You will need a digital caliper for this task. Carefully disassemble your laptop and locate the PCH.

If there’s an existing thermal pad, measure its compressed thickness. If no pad is present, measure the gap between the PCH chip and the heatsink.

Aim for a thermal pad thickness that is slightly thicker than your measured gap.

It should compress slightly to ensure full contact without bending the motherboard.

For shims, aim for a thickness that precisely matches the gap, plus a minimal allowance for thermal paste.

Installation: Precision is Key

This is an advanced procedure, requiring care and attention to detail. Proceed only if you are confident with laptop disassembly.

Preparation Checklist

• Acquire appropriate thermal pads (e.g., Thermal Grizzly Minus Pad 8) or copper shims.
• Gather tools: small Phillips head screwdrivers, plastic pry tools, digital calipers, isopropyl alcohol, and lint-free cloths.
