MSI GeForce RTX 3080 SUPRIM X 10GB: Thermal Pad Guide (Detailed Sizes 1.5, 2, 3mm)

Why Correct Thermal Pads are Crucial for Your MSI RTX 3080 SUPRIM X

Thermal pads are essential for bridging the gaps between vital heat-generating components—such as VRAM (Video Random Access Memory) on both the front and back, VRMs (Voltage Regulator Modules), and other ICs—and the card's massive, high-performance heatsink and backplate assembly. Efficient heat transfer is paramount to prevent these components from overheating, especially on a card of this caliber.

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

Elevated Operating Temperatures: This can cause thermal throttling, where the GPU reduces its performance to prevent heat damage, undermining the SUPRIM X's capabilities.
System Instability: Overheating may result in crashes, visual artifacts, or freezes during demanding gaming sessions or heavy creative workloads.
Reduced GPU Lifespan: Prolonged exposure to high temperatures can degrade sensitive electronic components over time.

Replacing thermal pads with new, high-quality ones matching the precise specifications is a key maintenance step to keep your SUPRIM X performing flawlessly.

Thermal Pad Replacement Options for MSI GeForce RTX 3080 SUPRIM X 10GB

You have a couple of approaches for replacing the thermal pads on your SUPRIM X:

Option 1: VRAM-Focused Replacement If your primary concern is VRAM temperatures, a targeted replacement can be performed:

VRAM (Front): Use 2mm thick thermal pads. A sheet of 85mm x 45mm x 2mm is generally sufficient to cut pads for all front VRAM modules.
VRAM (Back): Use 3mm thick thermal pads. A sheet of 85mm x 45mm x 3mm is generally sufficient for the back VRAM modules.

Option 2: Full Replacement (Recommended for Comprehensive Thermal Restoration) For a complete overhaul and the best possible thermal performance, replacing all pads using original dimensions is recommended. This requires thermal pad material in 1.5mm, 2mm, and 3mm thicknesses.

Required Sheet Materials for Full Replacement:

One (1) piece of 85mm x 45mm x 2mm thermal pad sheet.
Two (2) pieces of 85mm x 45mm x 3mm thermal pad sheets (or one larger sheet equivalent).
One (1) piece of 100mm x 100mm x 1.5mm thermal pad "slice" (or an 85x45mm sheet if smaller pieces are cut efficiently).

Note on "Pads on the side" Summary: The provided input also mentioned "Pads on the side: 1.5mm, 3mm." For a full detailed replacement using the original sizes listed above, you'll see that front "side" pads are primarily 1.5mm and 2mm, while back side pads are 3mm. The detailed list is your most accurate guide for a full job. The initial narrative's suggestion of needing a "100x100x1.5mm slice to cover all those surface on the side" primarily refers to the numerous 1.5mm pads on the front.

Why Choose Fehonda Thermal Pads?

For a premium card like the MSI RTX 3080 SUPRIM X, using high-quality thermal pads is essential. Fehonda pads are recommended because:

Premium Quality: Made from high-grade materials ensuring superior thermal conductivity and durability.
Enhanced Cooling: Engineered to efficiently transfer heat, critical for reducing temperatures on a high-power GPU.
Expertise: Fehonda specializes in thermal interface solutions.
Versatile Solutions: Offering sheets in various precise thicknesses (1.5mm, 2mm, 3mm) needed for the SUPRIM X.

Tips for Replacing Your GPU Thermal Pads (MSI RTX 3080 SUPRIM X)

This is an advanced procedure due to the card's complexity. If you are not highly experienced, seek professional help or follow extremely detailed, model-specific video guides. Refer to any "attached pictures" or visual guides you have for pad placements.

Preparation: Gather tools: Fehonda thermal pad sheets (1.5mm, 2mm, 3mm as per full replacement list), precision screwdrivers, sharp craft knife/scissors, ruler/calipers, non-metallic prying tools, isopropyl alcohol (90%+), lint-free cloths, and an anti-static wrist strap.
Disassembly & Component Identification: Carefully disassemble your SUPRIM X. Meticulously identify each component corresponding to the "original sizes" list if doing a full replacement. If VRAM-only, identify all front and back VRAM modules.
Remove Old Pads & Clean: Gently remove all old pads. Thoroughly clean component surfaces and heatsink/backplate contact points with isopropyl alcohol. Ensure complete dryness.
Cut and Apply New Pads:
- For Full Replacement: Precisely cut new pads from the correct thickness sheets according to the detailed "original sizes" list.
- For VRAM-Only: Measure your VRAM modules and cut pads from your 2mm (front) and 3mm (back) sheets.
- Apply carefully, removing protective films and ensuring good contact.
Reapply GPU Thermal Paste: Clean the GPU die and apply fresh, high-quality thermal paste.
Reassembly: Carefully reassemble, ensuring even pressure from the heatsink and backplate. The SUPRIM X cooler is substantial; follow torque patterns if specified in service manuals. Do not overtighten.
Testing: Install and monitor temperatures under load to verify success.

Note on Other Backplate Pads: The narrative mentioned some very thick backplate pads (beyond VRAM) "are not necessarily have to be changed." While the detailed list for the back side covers several pads (presumably VRAM and key VRM areas), if you encounter other extremely thick pads that are not listed and appear in good condition, you might prioritize replacing only those detailed or those showing clear degradation.

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