This 4-conductor Y-cable allows two fans to be powered from a single cable via this Noctua NA-YC1 splitter.
Warning: The OPTIONAL shipping method (large envelope first class mail) is the most economical, but does NOT INCLUDE a TRACKING number, and USPS does not seem to care about speed of delivery for it. If the buyer wants a tracking number, be sure to select the alternate USPS Ground Advantage. USPS has been very slow delivering first class mail--typically at least 7 days, and sometimes over 12 days. USPS charges over twice as much to handle Ground Advantage, but it is moving faster than first class letters in 2026. This ships within 2 business days, but because people get impatient when they choose the slow first class mail method which can take two weeks for delivery, a longer handling time is shown.
