However, you can control the rate at which they spin using fan control software.Ī good fan control application makes it easier to tune the CPU and GPU fans for maximum performance with minimum noise. But sometimes, the fans might spin at a high RPM by default, which can cause the system to get noisy. Generally, they spin at different RPMs (Rotation Per Minutes) depending on the load on your system. Something like that might be the most compact and straightforward option, if you don't have another USB header to spare.The fans inside your computer keep the component and the system cool. Those will plug into a USB 2.0 header and split it into two or more headers, just like a USB hub, only for internal headers. Some will also have a plug to receive power from the PSU though, so don't mistake that for a USB header.Īnother option would be a USB 2.0 header splitter. Most USB 3.0 cards with an internal header will probably have a 3.0 header though, so an adapter may still be necessary. Those tend to start around $15 or so on sites like eBay, though you may be able to find some for less if you are willing to wait longer for shipment from China. Most of those add additional external USB ports, but some also include an additional internal header (or only internal headers in some cases). If you don't have a free USB header of any kind, but do have a PCIe 1x or larger slot available, it's also possible to add a USB PCIe card. You would want to make sure you get one with the metal pins on the smaller 9-pin 2.0 side, and holes on the larger 3.0 side if you did though, as adapters with the opposite arrangement also exist. If not, you can get a USB 3.0 to 2.0 header adapter for a few dollars or so off eBay, and use it to convert the header into a 2.0 one.

Click to expand.The cooler's USB adapter connects to a USB 2.0 header, though your motherboard probably has at least one of the larger 3.0 headers as well, unless you are also using that.
