I’m looking for a fan to circulate air in a fridge not to cool electrical equipment down.** A: I don't know but I'd imagine condensation would be a problem and if very cold, ice. I don't think the unit is sealed well enough against moisture. Maybe a unit which is meant to work underwater might be better **Q: Do I need to buy sticky feet for this product or will it remain still whilst I play on my ps4?** A: The rubber feet stop the fan's vibration through to the unit, and will stop it creeping or sliding, keeping it firm. Any further demands above this may require sticky feet. This is a great product which is close to silent in its operation. **Q: how long is the usb cable?** A: It's well over a meter. Somewhere between 1.5 and 2m. The connector to daisy chain along is about a 1/4 of the way from the fan. Good bit of kit, very quiet. Keeping my ex2 has drive at about 30 degrees, was getting really hot before. **Q: Can this be mounted easily into the back of a cabinet?** A: Depends what you mean by 'cabinet' & also on your competence level. Great little gadget and I use one of mine hung against an amplifier side vent via a hook made from a paper clip. Buy it, you will not be anything other than pleased. ## Frequently Bought Together - AC Infinity MULTIFAN S1, Quiet 80mm USB Fan, UL-Certified for Receiver DVR PlayStation Xbox Computer Cabinet Cooling - AC Infinity Turbo Fan Power Adapter, for MULTIFAN Series USB Fans - AC Infinity MULTIFAN S5, Quiet Dual 80mm USB Fan, UL-Certified for Receiver DVR PlayStation Xbox Computer Cabinet Cooling --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tw/products/60449076-ac-infinity-multifan-s1-quiet-80mm-usb-fan-ul-certified](https://www.desertcart.tw/products/60449076-ac-infinity-multifan-s1-quiet-80mm-usb-fan-ul-certified) --- *Product available on Desertcart Taiwan* *Store origin: TW* *Last updated: 2026-09-30*
