About Slot fan
Keep your system cool with this add-in PCI expansion slot cooling fan. This quiet-running fan mounts to your computer's case and exhausts warm air out of adjacent PCI or ISA expansion slots, improving video card (GPU) performance by preventing overheating. It also helps prevent throttling, in which your CPU or GPU deliberately slows down its operations to avoid overheating. https://www.fomototo.com/
The fan is powered through a standard LP4 pass through plug from your power supply and features an Ever Lubricate bearing for longevity. Its high efficiency blade design and brushless motor help to move 36 CFM of air, keeping your expansion cards cool. It can even be daisy-chained with other fans to reduce cable clutter.
This is the perfect cooling solution for your hot-running 3D accelerator or older PCI graphics card. By maintaining a cooler temperature you can dramatically improve performance and increase the lifespan of your hardware. By exhausting the warm air from your expansion slots, this fan can directly target areas where other case fans may miss. Cooler temperatures reduce the risk of premature hardware failure, so a simple yet effective cooling solution like this one can save you money and time in the long run.
