President Electronics designed the radio to accept up to two ACMD901 fans on the rear heatsink and controls both automatically through the APM system. The single-fan kit is a starter configuration; the two-fan setup is the maximum cooling the radio was designed for.\u003c\/p\u003e\n\n\u003ch4\u003eDo I really need two fans or is one enough?\u003c\/h4\u003e\n\u003cp\u003eOne fan is enough for most operators — trucker use, moderate SSB, mixed-mode operation. Two fans are the recommended setup if you run high-duty-cycle SSB DX sessions, long repeater nets, extended base station use, or operate in a hot climate. Two fans also protect your finals better long-term by keeping peak internal temperatures lower.\u003c\/p\u003e\n\n\u003ch4\u003eIs the dual fan kit noticeably louder than one fan?\u003c\/h4\u003e\n\u003cp\u003eOnly marginally. Both fans run under APM control and only spin up when the chassis is warm. When the fans are engaged, two 40 mm fans produce slightly more airflow noise than one — but they also cool the chassis faster and cycle off sooner, so the total on-time is often less than a single fan working harder alone.\u003c\/p\u003e\n\n\u003ch4\u003eWill installing two fans void my President warranty?\u003c\/h4\u003e\n\u003cp\u003eNo. The ACMD901 is a factory-approved accessory. Each kit includes two replacement warranty stickers (four total in the two-pack) specifically so you can restore the warranty seals after installation.\u003c\/p\u003e\n\n\u003ch4\u003eCan I install these myself?\u003c\/h4\u003e\n\u003cp\u003eMost operators install the dual kit themselves in 30-45 minutes with basic hand tools. The 2-pin connectors are plug-and-play — no soldering, no splicing. Full instructions are included with each fan.\u003c\/p\u003e\n\n\u003ch4\u003eAre these different from the single-fan kit, or identical parts?\u003c\/h4\u003e\n\u003cp\u003eIdentical parts. Each ACMD901 in the two-pack is the same OEM President fan kit sold in our single-fan listing — you just receive two of them together, packaged for the dual-fan setup the Washington was engineered for.\u003c\/p\u003e\n\n\u003ch4\u003eCan I run these on a Washington-100 or only the older 80W Washington?\u003c\/h4\u003e\n\u003cp\u003eBoth. President Electronics kept the same chassis, heatsink mounting pattern, and internal fan header layout across the older 80W Washington and the current 100W Washington, so the ACMD901 dual kit is a universal fit across every version of the radio.\u003c\/p\u003e\n\n\u003ch3\u003eReady to order\u003c\/h3\u003e\n\n\u003cp\u003eAdd the ACMD901 dual fan kit to your cart with your \u003ca href=\"\/products\/president-10-meter-radio-president-washington-10-meter-radio\"\u003ePresident Washington radio\u003c\/a\u003e for the maximum-cooling factory-approved setup.
