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 ### ⭐⭐⭐⭐⭐ It's a server fan, not a normal desktop PC fan. *by N***R on May 10, 2025* I bought this as a cheap fan to pair with my Noctua as my motherboard takes four-pin connector and with the exception of that Noctua all I have are 3-pin 80mm fans. The Noctua came with some adaptors, including a splitter and noise reducer. When I first fired this baby up when it was connected to the splitter with my Noctua, it was louder than a jet engine. I ended up hooking the noise reducer between it and the splitter and it quieted right down. Even with the noise reducer, it has great airflow. It was after I set it up that I went back to the product page to realize it's a server fan. Explained the noise and the fact it was cheap. It's actually a good fan, it was my fault for not paying attention about it being more for servers than normal desktop PCs. So yeah, five stars due it it's ability to keep my PC cool. ### ⭐⭐⭐⭐⭐ Loud, but great air movement. *by A***M on August 3, 2025* I put these in a server to replace some of the old 80mm fans. They're definitely loud, but that's what I expect from something this small, that moves this much air. Good price for the amount of air it's moving. ### ⭐⭐⭐⭐ It does what a fan is supposed to do, but at a price, and I'm not talking about money. *by R***Q on October 19, 2023* If you need a fan to blow lots of air and don't care about the noise, look no further. It works great. It's not the rush of air that is so annoying though, but the double ball bearings make a loud harmonic wine, even at low speed. It's a trade off and something you want to think about before deciding. I realized I couldn't live with the noise after a few minutes, but that's just me. Maybe you're deaf or maybe you're used to the sound of a jet engine in your living room, then you're golden. Maybe you want to put it into your wife's computer as a joke. But if you reside in hell, I think it's perfect. It will keep your CPU cool no matter how hot it gets down there. ## 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.bo/products/178713143-3-14inch-4pin](https://www.desertcart.bo/products/178713143-3-14inch-4pin) --- *Product available on Desertcart Bolivia* *Store origin: BO* *Last updated: 2026-04-29*
