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 ### ⭐⭐⭐⭐⭐ No nonsense mass air flow *by on Reviewed in the United States 10 January 2025* I got these to replace my aging bronze bushed 80mm exhaust fans, my case uses 4 80mm fans for exhaust.These things move a ton of air, they seem well made.They are loud, i already knew this, i could care less about having a silent case.I ran them for a short time at 100%, was like an SR71 Blackbird spooling up for take off and stuff began blowing around the wall.They create a lot of air pressure.Presently running them at 30% until the case temps climb up ### ⭐⭐⭐⭐⭐ It's a server fan, not a normal desktop PC fan. *by on Reviewed in the United States 10 May 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. ### ⭐⭐⭐⭐⭐ 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. ## Frequently Bought Together - Wathai 80mm x 38mm High Static Pressure Fan 12V 4 Pin Dual Ball PWM 8038 High CFM for PC CPU Cooler GPU Server Computerc Case Cooling - Wathai 12038 120mm x 38mm PWM Computer PC Case Fan 12V 4pin 5300rpm 230 CFM High Airflow Duall Ball CFM FG DC Brushless Cooling Fan - ARCTIC S8038-10K - Server Fan, 80x80x38 mm, 500–10000 RPM, PWM Regulated, 4-pin Connector, 12 V DC, Rack Cooling Fan - Black --- ## 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.us/products/454917600-wathai-4pin-pwm-dc-12v-80mm-high-cfm-fan-12](https://www.desertcart.us/products/454917600-wathai-4pin-pwm-dc-12v-80mm-high-cfm-fan-12) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-08-22*
