Refurbished GPUs are ideal for deployment for large-scale commercial uses. For these products, gpuShack honors conditions set forth under the gpuShack Warranty Agreement for a period of six months, beginning from the date of purchase.
All GPUs are thoroughly tested and guaranteed free from performance-affecting defects. All products sold on gpuShack come in plain packaging with no manuals, documents, cables, drivers, or software (except where stated) and only the actual GPU is included. Some GPUs' heatsinks, fans, or shrouds, may have light cosmetic damage such as light scratches.
The powerful modular fan upgrade allows for average operating temperature 10C colder compared to manufacturer stock fans. The modular fan uses 6+ watts, typically 4x more powerful than manufacturer 1.5+ watt stock fans. Ideal for deployment for large-scale commercial uses.
