It works ### ⭐⭐⭐⭐⭐ Review *by A***Y on 9 June 2021* When I first set up the fan and turned it on, there was a clicking noise. It sounded like the fan was hitting the housing. I turned it off, and then back on. I turned the fan speed up as high as it would go, and the clicking stopped. The clicking has not returned at any speed setting. The fan has been running non-stop for about 2 weeks. I should add that Mars Hydro contacted me a couple of days after my purchase to inform me that there might be issues with the fan, and if there were to let them know and they will take would take care of it. They also offered me a free 5gl grow bag. ## Frequently Bought Together - MARS HYDRO 4 Inch Inline Fan Combo with Variable Speed Controller, Quiet Cooling Booster Fan,205 CFM Exhaust Fan for Grow Tents and Hydroponics - MARS HYDRO TS1000 150W LED Grow Light for Indoor Plants, with Patented Reflector, 5 Levels Dimmable Lights Daisy Chain Full Spectrum Growing Lamps for Seedlings Veg Bloom in 2x2/3x3 Grow Tent --- ## 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.sn/products/397054091-4-inch-inline-fan-carbon-filter-ducting-kit-exhaust-fan](https://www.desertcart.sn/products/397054091-4-inch-inline-fan-carbon-filter-ducting-kit-exhaust-fan) --- *Product available on Desertcart Senegal* *Store origin: SN* *Last updated: 2026-04-26*
