MSI GeForce RTX 3070 Ti SUPRIM X 8G: Comprehensive Thermal Pad Replacement Guide

Why Correct Thermal Pads are Crucial for Your MSI RTX 3070 Ti SUPRIM X

Thermal pads are essential for bridging the gaps between heat-generating components—like VRAM (Video Random Access Memory), VRMs (Voltage Regulator Modules), and other ICs—and the card's sophisticated heatsink and backplate assembly. Efficient heat transfer is vital to prevent these components from overheating.

Using deteriorated, incorrectly sized, or improper thickness thermal pads can lead to:

• Elevated Temperatures: Potentially causing thermal throttling, where the GPU reduces its performance to avoid damage.
• System Instability: Overheating can result in crashes, visual artifacts, or freezes during demanding gaming or creative workloads.
• Reduced GPU Lifespan: Prolonged exposure to excessive heat can degrade components over time.

Replacing thermal pads with new, high-quality ones of the correct thicknesses is a key maintenance step to keep your SUPRIM X performing at its best.

Recommended Thermal Pad Thicknesses for MSI GeForce RTX 3070 Ti SUPRIM X 8G

The MSI RTX 3070 Ti SUPRIM X 8G utilizes a range of thermal pad thicknesses for different areas of the card. Please refer to your own visual guides (e.g., a "photo with color marks" if you have one from the source of this information) for precise locations of some side pads.

Front Side of PCB:

• VRAMs (Front): Requires 2mm thick thermal pads.
  • One sheet of 85mm x 45mm x 2mm is reported to be more than enough material to cut and replace all pads on the front side of the VRAMs.
• Capacitors on the side (reportedly marked "Yellow" in some visual guides): Requires 1.5mm thick thermal pads.
  • Users will need to measure the dimensions (length and width) of these components and cut pads from a 1.5mm thick sheet.
• Smaller components on the side (reportedly marked "Blue" in some visual guides): Requires 1mm thick thermal pads.
  • Users will need to measure the dimensions (length and width) of these components and cut pads from a 1mm thick sheet.

Back Side of PCB (Under Backplate):

• VRAMs (Back): This is a critical area requiring 4mm thick thermal pads.
  • The source information mentions "2 pieces of 85x45x2mm - It's 4mm thick!" This is somewhat ambiguous. It strongly indicates that the target thickness for the back VRAM pads is indeed 4mm.
  • To achieve this 4mm thickness, you would either need to source 4mm thick thermal pads directly, or if you only have 2mm pads, you would need to carefully stack two layers of 2mm pads for each VRAM module on the back. Stacking should be done with high-quality, compressible pads to ensure good contact, but a single 4mm pad is generally preferred if available. The "2 pieces of 85x45x2mm" might refer to needing enough 2mm material to cover the area of two VRAM groups if stacking, or it might be an error in conveying the need for 4mm pads. Prioritize achieving the 4mm thickness.
• Other Backplate Pads: The general backplate area has "extremely height thermal pads," estimated to be between 3.5mm – 4mm.
  • Important Note: It's stated that these general backplate pads (and other minor pads not detailed) "are not necessarily have to be changed." Focus on the VRAM (front and back) and the specified side components unless you observe significant degradation on other backplate pads.

Purchasing Recommendation Summary: To cover the detailed areas, you will likely need:

• One sheet of 85mm x 45mm x 2mm (for Front VRAMs).
• Sheet material of 1.5mm thickness (for "Yellow" side components).
• Sheet material of 1mm thickness (for "Blue" side components).
• 4mm thick thermal pad material for Back VRAMs (or double the amount of 2mm material if careful stacking is your only option).
• Optionally, 3.5mm or 4mm material if you decide to replace other general backplate pads.

Crucial Action: Measure Individual Pads! Except for the front VRAMs where a sheet size is suggested for cutting, users must carefully measure the length and width of all other components (side capacitors, smaller side components, back VRAMs) on their specific card during disassembly to determine the exact sizes to cut from the appropriate thickness sheets.

Why Choose Fehonda Thermal Pads?

When replacing thermal pads, especially with various thicknesses and custom cutting involved, quality is essential. Fehonda thermal pads are a strong contender:

• Premium Quality: Made from high-grade materials for excellent thermal conductivity and longevity.
• Enhanced Cooling: Designed to efficiently transfer heat, helping to lower component temperatures.
• Expertise: Fehonda focuses on thermal solutions, understanding the needs of modern electronics.
• Versatile Solutions: Offering sheets in various thicknesses allows for the flexibility needed for complex cards like the SUPRIM X.

Tips for Replacing Your GPU Thermal Pads (MSI RTX 3070 Ti SUPRIM X)

This process requires significant care due to the card's complexity and the varied pad thicknesses. If inexperienced, seek professional help or follow very detailed model-specific video guides.

1. Preparation: Gather tools: Fehonda thermal pad sheets (1mm, 1.5mm, 2mm, and 4mm or 2x2mm for stacking), precision screwdrivers, sharp craft knife/scissors, ruler/calipers, non-metallic prying tools, isopropyl alcohol (90%+), lint-free cloths, and an anti-static wrist strap.
2. Consult Visual Guides: Refer to any color-coded images or disassembly guides you have for identifying the "Yellow" (1.5mm) and "Blue" (1mm) side components.
3. Disassembly & Measurement: Carefully disassemble your SUPRIM X. Meticulously measure all components requiring pads to determine the length and width for cutting from your sheets of the correct thickness. Pay extreme attention to identifying front VRAMs (2mm), side components (1mm & 1.5mm), and especially the back VRAMs (target 4mm).
4. Remove Old Pads & Clean: Gently remove all old pads. Thoroughly clean component surfaces and heatsink/backplate contact points with isopropyl alcohol. Ensure dryness.
5. Cut and Apply New Pads: Precisely cut pads from the correct thickness sheets. For back VRAMs, if using 4mm pads, apply directly. If stacking two 2mm pads, ensure they are aligned perfectly and from a compressible material; this is less ideal than a single 4mm pad. Apply to components after removing one side of the protective film, then remove the other before reassembly.
6. Reapply GPU Thermal Paste: Clean the GPU die and apply fresh, high-quality thermal paste.
7. Reassembly: Carefully reassemble, ensuring even pressure. Do not overtighten.
8. Testing: Install and monitor temperatures under load to verify success.

Disclaimer: GPU disassembly is risky and may void your warranty. Proceed at your own risk.

Conclusion: Maintain Your SUPRIM X's Elite Cooling

Proper thermal pad replacement is vital for the MSI GeForce RTX 3070 Ti SUPRIM X 8G to continue delivering its top-tier performance. By using high-quality Fehonda thermal pads of the correct thicknesses (2mm for front VRAM, 4mm for back VRAM, 1.5mm and 1mm for specified side components) and meticulously measuring and cutting each piece, you can ensure optimal heat dissipation, leading to a cooler, more stable, and longer-lasting graphics card. Remember the advice that general backplate pads may not need changing, allowing you to focus on the most critical areas.
