Model GPU Backplate Cooler W / Thermal

  • Dual 70 mm ball-bearing fans adjust 1 500–2 800 RPM for strong airflow at 16–20 dBA
  • 5 mm aviation-grade 6061 aluminium backplate spreads heat over a larger surface than thinner designs
  • Upgraded elastic latch secures the cooler on flat RTX 3090, 3080 or 3070 cards without tools
  • Included 1.2 mm 7 W thermal pad fills gaps between memory and heatsink for better transfer
  • Compact 180 × 90 × 15 mm footprint fits tight builds while keeping weight low

GPU Backplate Cooler for RTX 3090

This aluminium backplate cooler mounts on the memory side of a graphics card. It uses two 70 mm dual-ball-bearing PWM fans that spin between 1500 and 2800 RPM. The 1.5 mm aviation-grade 6061 plate adds structural rigidity while spreading heat. A 1.2 mm 7W thermal pad is included for the memory modules.

For builders with flat-back RTX 3090 3080 3070 cards

The elastic latch secures the assembly on any flat metal backplate, making installation quick and tool-free. Noise stays between 16 and 20 dBA at full speed. Buyers whose cards have a curved backplate, a plastic shroud covering the memory area, or limited clearance between the PCB and the case side panel cannot use this cooler.

1.5 mm aluminium thickness decides fit

The 1.5 mm plate is thicker than common 1 mm alternatives, so it needs a flat mounting surface and enough vertical space above the memory chips. If the card’s backplate is uneven or the gap to the side panel is tight, the cooler will not seat correctly and memory temperatures will not improve.

Questions about this item

Does my RTX 3090 need a flat backplate surface for the 1.5mm aluminum heatsink to make proper contact?

Yes, the cooler is designed for flat universal graphics cards and must be installed on a flat surface; the elastic latch secures it once aligned.

Will the dual 70mm PWM fans connect to a standard 4-pin 2510 header on my existing graphics card?

The fans use a 4-pin 2510 PWM connector; verify your card has a matching header or an adapter before installation.

How can I confirm the cooler is operating correctly after mounting it on my RTX 3080?

Fan speed should vary between 1500 and 2800 RPM based on temperature, and noise should stay within the 16 to 20 dBA range under load.
