This 3D-printed graphics card auxiliary cooling fan bracket is specifically designed for DIY enthusiasts, allowing standard case fans to directly blow cool air onto the graphics card. This effectively reduces the card’s full-load temperature, eliminating the headaches of thermal throttling and excessive fan noise.

The bracket features a snap-fit design that makes it easy to secure in the case or directly onto the graphics card. It’s compatible with mainstream 120mm case fans on the market, requiring no additional drilling or complex modifications—so even beginners can install it with ease. The bracket’s structure has been reinforced and optimized to resist deformation and breakage, ensuring stable airflow when paired with a fan. This helps efficiently dissipate heat from the graphics card’s PCB and memory chips, extending hardware lifespan and improving stability during gaming and productivity workloads.

✅ Compatible with standard 120mm case fans; highly versatile and universally applicable ✅ Tool-free snap-fit installation—no drilling required, making it quick and easy for novices ✅ Reinforced structural design ensures resistance to deformation and breakage, delivering long-term stability and reliability ✅ Optimized airflow directs cool air straight at the graphics card’s core and memory, effectively lowering full-load temperatures ✅ No support structures needed; beginner-friendly and easily printed using PLA or PLA+ filaments

Printing recommendations

• Layer height: 0.2 mm

• Wall thickness: 1.6 mm (thickening recommended to enhance bracket strength)

• Infill: 40–60% (provides better load-bearing capacity and vibration resistance, preventing deformation over time)

• Filament: Prioritize PETG or ABS (higher temperatures inside the case make PETG more heat-resistant and durable); PLA is also suitable for short-term use

• Supports: No additional supports required—simply print flat

Applicable scenarios

Upgrading cooling for older graphics cards, cooling gaming rigs, enhancing cooling for productivity-oriented graphics cards, optimizing airflow in DIY PC cases, cooling mining GPUs or used graphics cards, and retrofitting fanless graphics cards for passive cooling.
