Icom IC-7300 Noisy Fan Mod

This resource details a modification for the Icom IC-7300 transceiver to reduce cooling fan noise. The Icom IC-7300 uses a 12VDC fan run at approximately 6VDC, with a 10VDC 'kick' on transmit, which many users find too noisy. The modification involves replacing the stock fan with a Noctua NF-A8 PWM fan. This replacement fan is described as 'silent,' even during the initial 10V transmit kick. The page notes that the Noctua NF-A8 PWM fan is available on eBay in the UK for under £20. The modification is presented as a simple way to improve the operating experience of the rig. It also mentions that suitable 2-pin fan plugs with pre-attached wires are available on eBay to facilitate a neat installation. The page includes a picture of the new Noctua NF-A8 PWM fan and specifies the wiring: black for negative and yellow for positive.
