PowerColor Red Devil AMD Radeon RX 6800 XT: Thermal Pad Guide (1.5mm & 2mm)

Why Correct Thermal Pads are Crucial for Your Red Devil RX 6800 XT

Thermal pads are vital for your graphics card's cooling system. They bridge the microscopic air gaps between heat-generating components—such as the VRAM (Video Random Access Memory) modules, VRMs (Voltage Regulator Modules), MOSFETs, and other ICs on the PCB—and the card's substantial heatsink and backplate assembly. This direct contact ensures efficient heat transfer, preventing these sensitive components from overheating.

Using old, deteriorated, or incorrectly sized/thicknessed thermal pads can lead to several significant problems:

• Increased Operating Temperatures: This can cause thermal throttling, where the GPU intentionally reduces its clock speeds to prevent heat damage, directly impacting your gaming performance.
• System Instability: Overheating can manifest as game crashes, visual artifacts on your screen, or even unexpected system shutdowns.
• Reduced GPU Lifespan: Prolonged exposure to high temperatures can accelerate the wear and tear on electronic components, potentially reducing the overall lifespan of your valuable graphics card.

Replacing thermal pads with new, high-quality ones of the correct thicknesses for each specific component is an important maintenance step to keep your PowerColor Red Devil RX 6800 XT running optimally.

Recommended Thermal Pad Thicknesses for PowerColor Red Devil AMD Radeon RX 6800 XT

For the PowerColor Red Devil AMD Radeon RX 6800 XT, the information available indicates that the card utilizes a combination of 1.5mm and 2mm thick thermal pads across its various components.

CRITICAL NOTE ON IDENTIFICATION AND SPECIFIC DIMENSIONS: The provided information does not specify which exact components (e.g., VRAM, specific VRM sections, MOSFETs on front or back) use 1.5mm pads and which use 2mm pads. Furthermore, the length and width dimensions for any individual pads are not supplied.

Therefore, it is absolutely essential for users to:

1. Carefully disassemble their PowerColor Red Devil AMD Radeon RX 6800 XT card FIRST.
2. Identify all components that are currently using thermal pads (or appear to require them based on contact marks on the heatsink/backplate).
3. Meticulously measure the thickness of the original pads for each distinct component or group of components. If the original pads are too compressed or degraded to measure accurately, you will need to carefully assess the gap between the component and the heatsink/backplate to determine if a 1.5mm or 2mm pad is most appropriate for optimal contact without undue pressure.
4. Measure the length and width of each area where a thermal pad is needed.

Purchasing Recommendation: Based on the known required thicknesses, you will need to purchase thermal pad sheets of both:

• 1.5mm thickness
• 2mm thickness

A common starting point would be to acquire at least one sheet of 85mm x 45mm for each thickness (i.e., one 85x45x1.5mm sheet and one 85x45x2mm sheet). Depending on the number and size of the components on your specific card after disassembly and measurement, you may need more material of one or both thicknesses.

Why Choose Fehonda Thermal Pads?

When undertaking a thermal pad replacement where user measurement and precise application are paramount, the quality of the thermal pad material is crucial. Fehonda thermal pads are a recommended option due to several benefits:

• Premium Quality: Fehonda utilizes high-grade materials in their thermal pads, ensuring excellent thermal conductivity and durability for long-lasting, effective cooling.

• Expertise: Fehonda specializes in thermal interface materials, offering products designed with an understanding of the cooling needs of modern, high-performance electronics.
• Versatile Solutions: Providing thermal pads in various thicknesses and common sheet sizes (like 85x45mm) offers the flexibility to custom-cut pads for a wide variety of GPUs and component layouts, which is essential for this particular card given the lack of pre-defined dimensions.

Tips for Replacing Your GPU Thermal Pads (Red Devil RX 6800 XT - Measurement is Key!)

Replacing GPU thermal pads on a high-performance card like the Red Devil RX 6800 XT requires precision, care, and patience, especially as you will be determining the thickness placement and all dimensions yourself. If you are not experienced with GPU disassembly, consider seeking professional assistance or meticulously following detailed video guides specifically for your Red Devil RX 6800 XT model.

1. Preparation: Gather your tools: new Fehonda thermal pad sheets (both 1.5mm and 2mm thicknesses), a precision screwdriver set (likely including various bit types), a sharp craft knife or precision scissors for cutting pads, a ruler or digital calipers for measuring, non-metallic prying tools (optional), high-purity isopropyl alcohol (90%+), and lint-free cloths. An anti-static wrist strap is crucial to protect components.
2. Critical First Step - Disassembly, Identification, and Measurement: Carefully disassemble your graphics card. This is the most important phase.
   • Identify every component that uses a thermal pad (VRAM, VRMs, MOSFETs, inductors, etc., on both front and back if applicable).
   • For each component or group of identical components, carefully measure the thickness of the original pad. If unsure or if it's compressed, assess the gap. Determine if it needs a 1.5mm or 2mm pad.
   • Precisely measure the length and width of each area requiring a pad. Keep detailed notes.
3. Remove Old Pads & Clean: Gently remove all old thermal pad material. Thoroughly clean the surfaces of the components and the heatsink/backplate contact points with isopropyl alcohol to remove any oily residue or debris. Ensure surfaces are completely dry before applying new pads.
4. Cut New Pads: Based on YOUR measurements and YOUR thickness determinations for each specific location, carefully and precisely cut the new Fehonda thermal pads from the appropriate 1.5mm or 2mm sheets. Aim for clean, straight cuts. The pads should cover the entire surface of the component they are intended for without excessive overhang.
5. Apply New Pads: Remove the protective film from one side of a newly cut pad, apply it to the corresponding component (ensuring correct thickness is used for that specific location), then remove the film from the other side just before reattaching the heatsink or backplate. Ensure good contact.
6. Reapply GPU Thermal Paste: Since the heatsink is removed from the GPU die, you will also need to clean the old thermal paste from the GPU die and apply a fresh, even layer of new, high-quality thermal paste.
7. Reassembly: Carefully reassemble your graphics card, ensuring even pressure when reattaching the heatsink and backplate. Do not overtighten screws, as this can damage the PCB.
8. Testing: Install the card back into your PC and monitor temperatures under load (e.g., using benchmarking software or demanding games) to verify the success of the replacement and ensure temperatures are stable and within optimal ranges.

Where to Purchase Fehonda Thermal Pads

For reliable, high-quality Fehonda thermal pad sheets suitable for your PowerColor Red Devil AMD Radeon RX 6800 XT, online marketplaces like AliExpress are a common source.
