What's the max amps I can use for a power supply?** A: The unit at full speed pulls about .7 amps. My motherboard is capable of 1 amp on each fan header but I did have to get an ATX splitter with a sensor cable that goes to my MB as I ran out of fan headers to use and didn't want to use a basic splitter because each fan wouldn't receive the entire amperage they need. Not that I run them at 100% usually they are running between 30-60% but just in case I need them to operate at full speed they will. I just want the ability to if needed but if you had to use a basic splitter cord on a 1 amp header they would still run at about 70%. The motherboard still gets sensor data from one of the fans though so at least I don't have a dead sensor and I always run the two fans together at the same speed anyways. They run at 12 volts so if you're not plugging them into a motherboard I would find an adapter that would do 12 volts at 1 amp so you know that you're covered well. You can use an adapter that puts out more than 1 amp it will only use what it needs. If connecting directly to a power only you just need the red and black wires connected. You might be able to find an 80mm fan with an AC adapter I see some of them on here with them. The other two wires are used for computer fan header use and can be discarded if you aren't using them with a motherboard. These fans are extremely loud at full speed so you might want to end up using a 9 volt or 5 volt adapter anyways so they aren't at full speed. They put out a ton of air probably the strongest 80mm fans available but they also get quite loud. I have 4 in my computer case and if I tell my motherboard to run them at full speed it sounds like my computer is about to take off and fly. That was the point of me getting these fans was to make sure if my computer needed it that it could turn up the airflow as much as it wants. I'm actually using a very large ATX case but it's old school and can only take this size fan so I have two in the front and two in the back. I use the motherboard to control the speed and usually keep them at about 30% in normal use. If I'm heavily using my computer they might go up to 50-60%. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Is loud, but pushes a lot of air. *by on Reviewed in the United States 16 September 2026* This fan can really push some air. I mainly used it for some ESP32 projects and to show how PWM works, and this fan worked perfectly for it. If you're looking for something quiet, this is not that fan. In addition to pushing out a lot of air, it is loud. As to the speed control, if you set up a PWM signal to it, then you're good to adjust to your hearts desire. 12 VDC power supply is easy to deal with, and comes with the hardware kit to put the grates over it so you don't hit your fingers on it or other things. Overall, I am very pleased with the fan for the price is cost. ### ⭐⭐⭐⭐⭐ Good airflow, noisy *by on Reviewed in Canada 31 December 2024* Installed in RackChoice 2U micro ATX server rack. Noisy, but less than my HP Proliant DL380P. Very good airflow. ### ⭐⭐⭐⭐⭐ 商品について *by on Reviewed in Japan 5 February 2025* 冷却能力は高いですが、若干風切り音が気になります。商品としては十分機能しています。静かな部屋での使用には向かないですね。 ## Frequently Bought Together - Wathai 80mm x 25mm PC Computer Case Fan PWM 12V 4Pin Fan High Static Pressure for Server Box Enclosure CPU Cooler Cooling - JBtek All Black Sleeved PWM Fan Splitter Cable 1 to 2 Converter, 2 Pack - Noctua NF-R8 redux-1800 PWM, High Performance Cooling Fan, 4-Pin, 1800 RPM (80mm, Grey) --- ## 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.no/products/419918949-wathai-4-pin-80mm-pc-computer-case-fan-12v-high](https://www.desertcart.no/products/419918949-wathai-4-pin-80mm-pc-computer-case-fan-12v-high) --- *Product available on Desertcart Norway* *Store origin: NO* *Last updated: 2026-09-23*
