Why Correct Thermal Pads are Crucial for Your PNY RTX 3070 XLR8
Thermal pads are a critical interface within your graphics card, responsible for transferring heat away from vital components. These include VRAM (Video Random Access Memory) modules, VRMs (Voltage Regulator Modules), and other integrated circuits (ICs) on the PCB, moving heat to the main heatsink assembly for dissipation. Efficient heat transfer is essential for preventing overheating and maintaining system stability.
Using degraded, old, or incorrectly sized thermal pads can lead to significant problems:
- Increased Operating Temperatures: This can trigger thermal throttling, where the GPU reduces its performance (clock speeds) to prevent heat damage, directly impacting your experience.
- System Instability: Overheating may lead to game crashes, visual artifacts, system freezes, or other frustrating interruptions during intensive use.
- Reduced GPU Lifespan: Continuous exposure to high temperatures can accelerate the degradation of electronic components, potentially shortening the operational life of your valuable graphics card.
Replacing thermal pads with new, high-quality ones of the correct 1mm thickness is an important maintenance step to keep your PNY RTX 3070 XLR8 or Gainward RTX 3070 Phoenix running optimally.
Accurate Thermal Pad Sizes for PNY GeForce RTX 3070 XLR8 Gaming REVEL (and Gainward RTX 3070 Phoenix)
All thermal pads required for these models are reported to be 1mm thick. Below are the specific dimensions for each pad. Please pay close attention to the notes regarding Pads A (11) and B (10), as there are potential discrepancies in the initially reported sizes versus what might be expected or more common for similar components. The original picture reference was from a Gainward model.
Specific Pad Dimensions (All 1mm Thick):
- Pad A (11): 73.7mm x 5.2mm x 1mm
- Important Note: This listed dimension is reported as potentially incorrect. It is strongly suggested that the actual size for Pad A (11) should be between 40mm x 15mm – 50mm x 15mm. Users must verify this dimension during disassembly by measuring the component or the old pad.
- Pad B (10): 82.1mm x 5.2mm x 1mm
- Important Note: Similar to Pad A, this listed dimension is reported as potentially incorrect. It is strongly suggested that the actual size for Pad B (10) should be between 40mm x 15mm – 50mm x 15mm. Users must verify this dimension during disassembly.
- Pad C (12): 27.1mm x 14.2mm x 1mm
- Pad D (1): 61mm x 5.5mm x 1mm
- Pad D (7): 9.5mm x 9.5mm x 1mm
- Pad D (3, 4, 5, 6): Four (4) pieces, each 7mm x 7mm x 1mm
- Pad D (2): 62mm x 7mm x 1mm
- Pad D (8, 9): Two (2) pieces, each 20mm x 7mm x 1mm
Purchasing Recommendation:
To cover all required parts on the front of the PCB for these cards, you will need a substantial amount of 1mm thick thermal pad material. It is recommended to acquire:
- Two (2) pieces of 85mm x 45mm x 1.0mm thermal pad sheets.
This should provide enough material to cut all the individual pieces listed above, allowing for some margin for error, especially when verifying the sizes for Pads A and B.

Tips for Replacing Your GPU Thermal Pads
Replacing GPU thermal pads requires precision, patience, and care. If you are unfamiliar with GPU disassembly, it is highly advisable to seek professional assistance or meticulously follow detailed video guides specific to the PNY RTX 3070 XLR8 or Gainward RTX 3070 Phoenix.
- Preparation: Gather your tools: new Fehonda 1mm thermal pad sheets (two 85x45mm sheets recommended), a precision screwdriver set, a sharp craft knife or precision scissors, a ruler or digital calipers, non-metallic prying tools (optional), high-purity isopropyl alcohol (90%+), and lint-free cloths. An anti-static wrist strap is crucial.
- Disassembly & Measurement (Crucial for Pads A & B): Carefully disassemble your graphics card. Before removing the old Pads A (11) and B (10), meticulously measure their existing dimensions if they are intact, or carefully measure the components they cover. Compare these measurements to both the listed dimensions (73.7x5.2mm and 82.1x5.2mm) and the strongly suggested alternative range (40x15mm – 50x15mm) to determine the most accurate fit for your specific card. For other pads, verify their sizes against the components they cover.
- Remove Old Pads & Clean: Gently remove all old thermal pad material. Thoroughly clean all component surfaces and heatsink contact points with isopropyl alcohol to remove any residue. Ensure surfaces are completely dry before applying new pads.
- Cut New Pads: Based on your verified measurements (especially critical for Pads A and B), precisely cut the new 1mm thick Fehonda thermal pads. Aim for clean, straight cuts.
- Apply New Pads: Remove protective film from one side of each pad, apply it to the designated component, then remove the other film just before reattaching the heatsink. Ensure good, even contact.
- Reapply GPU Thermal Paste: Since the heatsink is removed, 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 all components are correctly aligned and the heatsink applies even pressure. Do not overtighten screws.
- Testing: After reassembly, install the card back into your PC and monitor temperatures under load using appropriate software to confirm a successful replacement and improved thermal performance.
Disclaimer: Disassembling your graphics card may void its warranty and involves an inherent risk of damage if not performed correctly. Proceed at your own risk.
