And these folks have. I absolutely LOVE IT! Pros: It works like a charm keeping routers, laptops, YOU cool Examples: Wifi link in the garage gets super hot in the summer time. But this did the trick so my speeds are back up and connections are not dropping like they used to! I also use it on a verizon 5G wifi cell modem. It's like it was made for it. I also use it under my high performance laptop to keep it cool and this does it so so so well. No laptop fans buzzing all the time. Instead with two of these fans running in my office I barely notice them. The noise at best is white noise, but when you're working or on a call I would challenge you to hear them going. Cons: I am not a fan of the button control. I know why it was done this way, but I'm not a fan of it. When the power goes off, this won't turn back on. So that is a major bummer. I get away with it using UPS units, but a rocker switch would have made more sense. Instead of three speeds there's at least two and when the power blinks it comes back on when the power comes back on. Honestly I could change it myself but I'm so lazy lol These folks have done a fantastic job with this and frankly I'm sucker for folks willing to put in a little time to innovate something that patches a major hole in router and modem cooling. Thanks for making these, love it! Review: Works with a little attention. - One thing to take note of. When ordered the description calls out 5v usb power. When I got this the included user manual calls for a 12v 2amp power supply. Most 12v power supplies are wall chargers that use a barrel plug that needs to be removed. The fan side usb connection will need to be removed as well Another option is a usp swap for the barrel plug. Don't know why this change happened. There's no mention of the 12v 2A power requirement untill you get the user manual. Update, ordered a fan from a different company. It included a 5v usb supply with included fan speed control. So much better than this fan. Update, decided to try a normal 5v charger with this fan and it's working well. Still don't know why the manual called for a 12v power supply. I have it running to cool my modem. Will update if anything goes wrong. For now it's working well and perty quiet on the medium setting. Last update. It's been some time now and things are good. The wall chargers is still cool to the touch and the fans are still running. The modem is much cooler than without the fans. Normally warm but pertty cool now. Good quality great price, I can definitely recommend it after you get past the power supply misunderstanding. ## Features - 2 IN 1 USB Fan 120mm, 2 fans connect to one USB cable and work at the same time.

Thankfully my WD Black 8tb external is only on when I backup files. I would not use it for always on drives as it is noisy. But it does work, in the lowest speed it drops temp from 55-60 C to 35-40 C. ## Frequently Bought Together - Wathai High Airflow Router Cooling Fan for Computer Cooler TV Small Box DC 5V USB Power 120mm 240mm Fan with Multi Speed Controller - ELUTENG Dual USB Computer Cooling Fan - High Speed 120mm, Adjustable 5V USB Port Heatsink for Laptop, Receiver, DVR, PlayStation, Xbox, Desk, Computer, Cabinet Cooling - 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.id/products/155979613-240mm-usb-fan](https://www.desertcart.id/products/155979613-240mm-usb-fan) --- *Product available on Desertcart Indonesia* *Store origin: ID* *Last updated: 2026-04-23*
