Why Correct Thermal Pads are Crucial for Your PNY RTX 3090 XLR8 REVEL
Thermal pads are vital for conducting heat away from the potent GDDR6X VRAM modules (on both front and back), VRMs (Voltage Regulator Modules), and other critical components to the card's heatsink and backplate. Efficient heat dissipation is paramount for a card of this caliber.
Using incorrect thermal pad thicknesses can lead to:
- Poor Contact & Overheating: If pads are too thin, they won't make proper contact, leading to overheating. If too thick, they can put undue pressure on components or prevent the cooler from seating correctly on the GPU die.
- Performance Throttling: Overheated components, especially VRAM on an RTX 3090, will cause the card to reduce its performance significantly.
- System Instability & Reduced Lifespan: Chronic overheating can lead to crashes, artifacts, and shorten the card's operational life.
Thermal Pad Thicknesses by Revision for PNY GeForce RTX 3090 XLR8 Gaming REVEL
Here’s a breakdown of the reported thermal pad thicknesses for each revision:
Revision A:
- Front Components (including VRAM): 2mm
- Back Components (including VRAM, under backplate): 2mm
Revision B:
- Front Components (including VRAM): 1mm
- Back Components (including VRAM, under backplate): 2mm (Consistent with Revision A for the back)
Recommended Thermal Pad Sheets (for cutting individual pads):
Based on the revisions, here's what you'll need for the VRAM and general backplate components:
- For VRAMs on Revision A (Front): One (1) sheet of 85mm x 45mm x 2mm.
- For VRAMs on Revision B (Front): One (1) sheet of 85mm x 45mm x 1mm.
- For Backplate Components (including Back VRAM - for BOTH Revisions A & B): One (1) sheet of 85mm x 45mm x 2mm.
Important Note on Other Front-Side Components (VRMs, etc.): The information provided primarily distinguishes the front VRAM pad thickness based on revision and specifies the backplate pad thickness. For other components on the front side of the PCB (like VRMs, MOSFETs, etc.), you will need to:
- Determine your card's revision (which dictates the general front-side thickness – 1mm or 2mm).
- Meticulously measure these other front-side components during disassembly to cut pads of the correct length and width from your chosen front-side thickness sheet (1mm or 2mm).
Crucial Action: Disassemble and Measure! Regardless of the general sheet recommendations, users MUST carefully measure the length and width of all individual VRAM chips (front and back) and any other components requiring thermal pads on their specific PNY RTX 3090 XLR8 REVEL during disassembly. This will allow you to determine the exact sizes to cut from your chosen thermal pad sheets.

Tips for Replacing Your GPU Thermal Pads (PNY RTX 3090 XLR8 REVEL - Revision Awareness)
This process requires extreme care due to the card's value and the revision uncertainty. If inexperienced, seek professional help or follow very detailed, model-specific video guides.
- Preparation: Gather tools: Fehonda thermal pad sheets (it's safest to have one 85x45x1mm sheet and at least two 85x45x2mm sheets to cover both revisions and the backplate), precision screwdrivers, sharp craft knife/scissors, ruler/calipers, non-metallic prying tools, isopropyl alcohol (90%+), lint-free cloths, and an anti-static wrist strap.
- Critical First Step - Disassembly & Revision Identification/Measurement: Carefully disassemble your card primarily to identify the thickness of the pads on the front VRAM. This will indicate if you have Revision A (2mm front pads) or Revision B (1mm front pads). At this stage, also meticulously measure the Length x Width of ALL components needing pads (front VRAM, back VRAM, and any other front-side VRMs/components).
- Remove Old Pads & Clean: Gently remove all old pads. Thoroughly clean all component surfaces and heatsink/backplate contact points with isopropyl alcohol. Ensure complete dryness.
- Cut and Apply New Pads: Based on your identified revision and precise measurements, cut new pads from the correct thickness sheets.
- Front VRAM: Use 2mm pads if Revision A, or 1mm pads if Revision B.
- Back VRAM/Backplate components: Use 2mm pads.
- Other Front Components (VRMs, etc.): Use the same thickness as your front VRAM (1mm or 2mm depending on revision), cut to your measured L x W.
- Apply carefully after removing protective films.
- Reapply GPU Thermal Paste: Clean the GPU die and apply fresh, high-quality thermal paste.
- Reassembly: Carefully reassemble, ensuring even pressure. Do not overtighten screws.
- Testing: Install and monitor temperatures (especially VRAM junction) under heavy load.
Where to Purchase Fehonda Thermal Pads
For high-quality Fehonda thermal pad sheets suitable for your PNY GeForce RTX 3090 24GB XLR8 Gaming REVEL, check online marketplaces like AliExpress:

To be prepared for either revision:
- Purchase at least one (1) sheet of 85mm x 45mm x 1mm.
- Purchase at least two (2) sheets of 85mm x 45mm x 2mm (one for potential Rev A front, one for the backplate common to both revisions, and potentially for other front components if Rev A).
This approach ensures you have the necessary materials once you've identified your card's specific needs upon disassembly.
Conclusion: Navigate PNY RTX 3090 XLR8 REVEL Revisions for Optimal Cooling
Thermal pad replacement on the PNY GeForce RTX 3090 24GB XLR8 Gaming REVEL requires extra diligence due to the two manufacturing revisions affecting front-side pad thickness. Disassembling your card to measure and verify the required front-side thickness (1mm for Revision B, 2mm for Revision A) before applying new pads is paramount. For the back components (including VRAM), a 2mm thickness is consistently indicated. By using high-quality Fehonda thermal pads and meticulously following these guidelines, you can ensure your powerful GPU receives the optimal cooling it needs for sustained performance and longevity.
