Why Correct Thermal Pads are Crucial for Your EVGA RTX 3080 FTW3 ULTRA
Thermal pads are vital for your graphics card's cooling system. They bridge the microscopic gaps between heat-generating components—such as the VRAM (Video Random Access Memory) chips on both the front and back of the PCB, and various "pads on the side" like VRMs (Voltage Regulator Modules) and MOSFETs—and the card's substantial heatsink and backplate assembly. This direct contact facilitates 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 performance.
- Reduced Performance and Stability: You might experience lower frame rates in games, system crashes, or visual artifacts during demanding tasks.
- Shortened GPU Lifespan: Prolonged exposure to excessive heat 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 is an important maintenance step to keep your EVGA RTX 3080 FTW3 ULTRA GAMING performing at its legendary best.
Recommended Thermal Pad Sheets & Thicknesses for EVGA GeForce RTX 3080 FTW3 ULTRA GAMING
For the EVGA GeForce RTX 3080 FTW3 ULTRA GAMING, different thermal pad thicknesses are recommended for various sections of the card. You will typically purchase thermal pad sheets of these thicknesses and then cut the individual pads to the specific sizes needed for each component.
VRAM (Front Side of PCB):
- Required Sheet: Use one (1) sheet of 85mm x 45mm x 2mm thermal pad.
- Individual pads for all VRAM modules on the front will need to be carefully measured and cut from this 2mm thick sheet.
VRAM (Back Side of PCB - Under Backplate):
- Required Sheet: Use one (1) sheet of 85mm x 45mm x 3mm thermal pad.
- Individual pads for the VRAM modules on the back of the PCB will need to be measured and cut from this 3mm thick sheet.
"Pads on the side" (e.g., VRMs, MOSFETs, other components on the PCB):
- Required Thicknesses: These components require a mix of 1mm thick pads, and either 2mm OR 3mm thick pads for other specific areas (notably, "two narrow pads on the sides" have been reported to work well with both 2mm and 3mm).
- You will need to purchase a sheet of 1mm thick thermal pad material (e.g., an 85mm x 45mm x 1mm sheet).
- For the components that can take either 2mm or 3mm, you can utilize material from your VRAM front (2mm) or VRAM back (3mm) sheets, or purchase additional sheets if extensive coverage is needed. User discretion based on observed gaps during disassembly is advised for these optional thickness areas.
Important Note on Specific Pad Dimensions (Length x Width): Specific length and width dimensions for each individual pad on the EVGA RTX 3080 FTW3 ULTRA are not provided in the source information. Therefore, users will need to meticulously measure all components that require thermal pads (VRAMs on front and back, and all "pads on the side") on their specific card during disassembly. This will allow you to determine the exact length and width to cut from your chosen thermal pad sheets of the appropriate thicknesses (1mm, 2mm, and 3mm).

Tips for Replacing Your GPU Thermal Pads (Custom Cutting Required)
Replacing GPU thermal pads requires precision, care, and patience, particularly when you need to determine the precise thickness for certain "side" components and measure/cut all pads yourself. If you are not experienced with GPU disassembly, consider seeking professional assistance or meticulously following detailed video guides for your specific EVGA RTX 3080 FTW3 ULTRA model.
- Preparation: Gather your tools: new Fehonda thermal pad sheets (1mm, 2mm, and 3mm), a precision screwdriver set, 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.
- Disassembly & Identification/Measurement: Carefully disassemble your graphics card to expose all components with thermal pads on both the front and back of the PCB, as well as the side components.
- Front & Back VRAM: Measure the length and width of VRAM chips for cutting from your 2mm (front) and 3mm (back) sheets.
- Pads on the side: Identify components needing 1mm pads and measure them. For the "two narrow pads on the sides" and potentially others, assess the gap to decide whether 2mm or 3mm pads would provide optimal contact without excessive pressure. Measure their length and width.
- 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.
- Cut New Pads: Based on your measurements and thickness determinations, carefully and precisely cut the new Fehonda thermal pads from the appropriate sheets. Aim for clean, straight cuts. The pads should cover the entire surface of the component.
- 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), then remove the film from the other side just before reattaching the heatsink or backplate. Ensure good contact.
- 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.
- 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.
- 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 EVGA GeForce RTX 3080 FTW3 ULTRA GAMING, online marketplaces like AliExpress are a common source.
