XFX fans are equipped to run at the highest possible performance, while our Zero DB Fan System will also keep your fans running at efficient RPM in order to minimize annoying fan noise by lowering RPM all the way down to Zero RPM. When the heat is on during intense gaming, our fans will speed up as needed.
The Speedster series exemplifies a modern aerodynamic style through a clean and elegant design. It is a thoughtful design with the sole purpose of maximizing airflow to improve cooling and performance.
With each iteration of the XFX Merc series, we have simplified the design while improving performance. This newest iteration introduces our all-new ridged backplate design which increases the overall surface area by 33%, the results are increased in heat dissipation when paired with thermal pads.
Our new design features a straight-through airflow venting to significantly improve cooling and compliments the open design of the Ghost Thermal floating shroud design along with numerous other cooling features.
The XFX MERC 319 7800 XT uses a vapor chamber design, a more efficient method for heat dissipation than traditional cold plates alone. The vapor chamber can quickly quickly and efficiently transfer heat from the GPU and VRAM to the heat pipes, and then into the heatsink assembly.
We know enthusiast like options, so for the XFX MERC 319 7800 XT graphics cards, we are offering dual BIOS. Giving a backup BIOS in the case of a failed BIOS update or flash.
With a 14-phase power design, and a dedicated 9-phases for GPU GFX Core, the QICK 319 7800 XT provides you with stable gameplay and gives better power distribution across the VRMs. This allows the GPU to operate cooler at baseline but also has tremendous room to overclock thanks to XFX's increased power delivery BIOS.
The MERC 319 7800 XT GPUs utilize 13-blade structure fans that provide better endurance and efficiency over other designs. Reducing friction and heat these, fans operate quieter and have increased lifespan.
