Why Correct Thermal Pads are Crucial for Your TUF RTX 3080 OC
Thermal pads are critical for dissipating heat from vital components like VRAM (Video Random Access Memory) on both the front and back, VRMs (Voltage Regulator Modules), and other "pads on the side." They bridge the gap between these heat sources and the card's extensive heatsink assembly (including the additional VRAM heatsink). Efficient heat transfer is paramount.
Using old, worn, or improperly sized thermal pads can lead to:
- Increased Temperatures: This can cause thermal throttling, where the GPU reduces performance to prevent overheating.
- System Instability: You might experience crashes, artifacts, or freezes during demanding gaming sessions or creative workloads.
- Reduced GPU Lifespan: Prolonged exposure to high heat can degrade components over time.
Replacing thermal pads with new, high-quality ones ensures your TUF RTX 3080 OC's advanced cooling system functions optimally.
Accurate Thermal Pad Sheets & Dimensions for ASUS TUF Gaming GeForce RTX 3080 OC Edition
The ASUS TUF RTX 3080 OC requires thermal pads of 1mm, 2mm, and 3mm thicknesses for different areas. Due to the additional heatsink for VRAM, ensuring ample material for 2mm pads is particularly important.
Specific Pad Requirements:
VRAM (Front Side of PCB - Under the additional VRAM heatsink & main heatsink):
- Required Sheet & Thickness: Uses 2mm thick thermal pads.
- It's recommended to use at least one full sheet of 85mm x 45mm x 2mm thermal pad material. Given the "additional removable heatsink between the main heatsink and the VRAMs," the source suggests you might "better go with at least 2 pieces of 85x45x2mm slice" to ensure complete coverage for all VRAM modules and potentially related components needing 2mm thickness in this area. You will cut individual pads for each VRAM chip from this material.
VRAM (Back Side of PCB - Under Backplate):
- Required Sheet & Thickness: Uses 3mm thick thermal pads.
- It's recommended to use one full sheet of 85mm x 45mm x 3mm thermal pad material for the VRAM modules on the back. You will cut individual pads for each chip from this sheet.
Pad "Between the heatsinks":
- Dimensions: One (1) piece, 47mm x 10mm x 2mm
- This likely refers to a pad interfacing between sections of the main heatsink assembly or the additional VRAM heatsink.
"Pads on the side" (e.g., VRMs, MOSFETs, other PCB components):
- One (1) piece: 66mm x 12mm x 1mm
- One (1) piece: 100mm x 10mm x 1mm
- One (1) piece: 105mm x 6mm x 2mm
Purchasing Recommendation Summary:
To perform a full thermal pad replacement, you will need to acquire:
- 1mm thick thermal pad material: Sufficient for cutting two large strips (66x12mm and 100x10mm). An 85x45x1mm sheet should typically cover this, but a 100x100x1mm sheet would offer more flexibility.
- 2mm thick thermal pad material: Crucial for front VRAM, the pad between heatsinks, and one of the side pads. Given the advice, plan for at least two (2) sheets of 85mm x 45mm x 2mm, or one larger sheet (e.g., 100x100x2mm or more) to be safe.
- 3mm thick thermal pad material: For back VRAM. One sheet of 85mm x 45mm x 3mm.
Important Note: While sheet sizes are recommended for VRAM areas, and specific dimensions are given for other pads, users must always measure the components on their specific card during disassembly to confirm the exact length and width for cutting VRAM pads and to double-check the other specified dimensions.

Tips for Replacing Your GPU Thermal Pads (ASUS TUF RTX 3080 OC)
This process requires significant care due to the card's construction, including the additional VRAM heatsink. If inexperienced, seek professional help or follow very detailed model-specific video guides.
- Preparation: Gather tools: Fehonda thermal pad sheets (1mm, 2mm, 3mm as per recommendations), 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 & Identification: Carefully disassemble your card, paying attention to the order of heatsink layers, especially the additional VRAM heatsink. Identify all VRAM locations (front/back), the spot "between the heatsinks," and the "pads on the side."
- Measure & Verify: Measure all VRAM chips to determine the exact L x W for pads to be cut from your 2mm (front) and 3mm (back) sheets. Verify the dimensions for the other specified pads (47x10x2mm, 66x12x1mm, 100x10x1mm, 105x6x2mm) against your card's components.
- Remove Old Pads & Clean: Gently remove all old pads. Thoroughly clean component surfaces and heatsink contact points with isopropyl alcohol. Ensure dryness.
- Cut and Apply New Pads: Precisely cut new pads from the correct thickness sheets. Apply carefully, ensuring full coverage and good contact after removing protective films.
- Reapply GPU Thermal Paste: Clean the GPU die and apply fresh, high-quality thermal paste.
- Reassembly: Carefully reassemble, ensuring the additional VRAM heatsink and main heatsink are correctly seated with even pressure. Do not overtighten screws.
- Testing: Install and monitor temperatures under load to confirm a successful replacement.
Disclaimer: GPU disassembly is risky and may void your warranty. Proceed with extreme caution.
