Why Correct Thermal Pads are Crucial for Your SAPPHIRE RX 5700 XT Nitro
Thermal pads are essential for efficiently transferring heat from critical components on your graphics card—such as the GDDR6 VRAM (Video Random Access Memory) modules, VRMs (Voltage Regulator Modules), and other ICs on the front side—to the card's substantial heatsink. Additionally, pads on the backplate help dissipate heat from the rear of the PCB.
Using old, worn, or incorrectly sized/thicknessed thermal pads can lead to:
- Increased Operating Temperatures: This can cause thermal throttling, where the GPU reduces performance to prevent overheating.
- System Instability: Overheating may result in game crashes, screen artifacts, or freezes.
- Reduced GPU Lifespan: Prolonged exposure to high temperatures can degrade components over time.
Replacing thermal pads with new, high-quality ones of the correct specifications is key to keeping your RX 5700 XT Nitro running at its best.
Accurate Thermal Pad Sizes & Dimensions for SAPPHIRE Radeon RX 5700 XT Nitro 8GB
The SAPPHIRE Radeon RX 5700 XT Nitro 8GB utilizes several different thermal pad thicknesses and specific dimensions for optimal cooling.
Front Side of PCB:
1. VRAM (Video Random Access Memory - 8 GDDR6 Modules):
- Required Thickness: 1.0mm
- Specific Dimensions: Eight (8) pieces, each 15mm x 13mm x 1.0mm.
- Sheet Recommendation: Approximately, you will need at least one (1) package of 85mm x 45mm x 1.0mm thermal pad material to cut these 8 VRAM pads.
2. Rest of the Front Side Components (e.g., VRMs, MOSFETs):
- Required Thickness: 1.5mm
- Specific Dimensions:
- One (1) piece: 103mm x 7mm x 1.5mm
- Four (4) pieces, each: 6mm x 6mm x 1.5mm
- Sheet Recommendation: You will need another package of 85mm x 45mm x 1.5mm thermal pad material to cover these components.
Backplate:
Purchasing Recommendation Summary:
To perform a full specified thermal pad replacement, you will need:
- One (1) sheet of 85mm x 45mm x 1.0mm (for Front VRAM).
- One (1) sheet of 85mm x 45mm x 1.5mm (for other Front Side components).
- Sufficient 3.0mm thick material to cut one 103mm x 7mm piece (an 85x45x3mm sheet would be more than enough).
- Optionally, extra material of suitable thickness if you plan to add more pads to the backplate.

Tips for Replacing Your GPU Thermal Pads (SAPPHIRE RX 5700 XT Nitro)
This process demands care and precision. If you're not experienced with GPU disassembly, consider professional help or watch detailed video guides specific to your Nitro model.
- Preparation: Gather your tools: Fehonda thermal pad sheets (1mm, 1.5mm, 3mm, and any optional thicknesses), precision screwdrivers, a sharp craft knife or precision scissors, a ruler or calipers, non-metallic prying tools, isopropyl alcohol (90%+), lint-free cloths, and an anti-static wrist strap.
- Disassembly & Component Identification: Carefully disassemble your card. Identify the 8 VRAM modules, the locations for the 103x7x1.5mm and 6x6x1.5mm front pads, and the 103x7x3mm backplate stripe.
- Remove Old Pads & Clean: Gently remove all existing thermal pads. Thoroughly clean all component surfaces and corresponding heatsink/backplate contact points with isopropyl alcohol. Ensure complete dryness.
- Cut and Apply New Pads: Precisely cut new pads from the correct thickness sheets according to the dimensions listed above. Apply them carefully to the components after removing protective films, ensuring full coverage and good contact.
- Optional Backplate Pads: If adding extra pads to the backplate, measure the gaps behind VRAM or other hot areas and cut appropriate pieces from your leftover (or dedicated) thermal pad material.
- Reapply GPU Thermal Paste: Clean the GPU die and apply a fresh, even layer of high-quality thermal paste.
- Reassembly: Carefully reassemble your graphics card, ensuring the heatsink and backplate are correctly seated with even pressure. Do not overtighten screws.
- Testing: Install the card and monitor temperatures under load to verify the success of the replacement and ensure improved thermal performance.
