Best Electronic Cooling Fans of 2025

"I bought this for a receiver that runs a bit hot, and it works very well at keeping the temps down. The noise is not really noticeable when the amp and music are on. It's a fairly thin unit that fits well in limited space, and it’s a great value for the price. I plan to get another for my other receivers."

"I needed something to cool off three power amps in a cabinet. After opening the cabinet door and noticing the heat, I found this fan on Amazon. It is exactly what I needed. I placed it on top of my third amp, and it cooled everything off within minutes. The fan operates automatically when the temp hits 88 degrees, and it’s only an inch and a half tall, fitting perfectly in my setup."

"I use this with my Denon X4700H, which runs quite hot. It has an auto mode for fan speed and turn-on. Although it’s not as quiet as some PC fans, it does a decent job regulating the temperature. I plan to enhance its effectiveness by using weatherstripping tape to create a better seal around it."

"I purchased these fans due to Noctua's stellar reputation and was pleasantly surprised by their performance. They are incredibly quiet compared to my previous Phanteks fans, and even improved my GPU temperatures. The build quality is superb, and I appreciate the vibration dampeners that match my color theme. Highly recommended!"

"For the quietest fan money can buy, I definitely recommend this one. It maintains a low noise level while providing excellent airflow. However, I faced a minor issue with stripped screws in the assembly process, which was frustrating. Nevertheless, the fan works really well overall!"

"These fans have been a game-changer for my build. They push air quietly and efficiently, especially when I configure them for temperature control. I bought a second set for my front intake, and the difference is remarkable. Highly recommended for anyone looking to optimize their cooling!"

"This fan is extremely powerful but quite noisy. I use it to keep my USB hub cool, and it does a great job at that!"

"The product is self-explanatory and effectively moves a lot of air. Setup was quick and easy, and I appreciate the controller for speed adjustment, though it is noticeably loud even at lower speeds."

"I found these fans to be great quality. I installed them in my RV fridge to pull heat from the back and exhaust it from the bottom. Currently, they're on a manual switch as a temporary solution until I get my 12-volt fridge. Great product, works as intended."

"For the price, they work well. I was surprised by how quiet they are. They provide enough strength for my application in creating a soundproof enclosure."

"I’ve been using one of these fans to cool a piece of radio equipment. They are pretty standard fans, but the thin blades and nice pitch are a plus. They include guards, which is a good feature. Fairly quiet, though not completely silent."

"I needed a cooling solution for my Onkyo TX-NR7100, which was constantly overheating. After trying various options, I decided to go with Noctua fans because of their exceptional build quality and quiet operation. With the included LNA cables, the noise level is just a whisper-quiet 34 dBA while maintaining solid airflow. The cooling performance is excellent; I rarely see temperatures above 83F-84F. The 6-year warranty is also a bonus."

"I replaced the stock fan in my desktop with a Noctua fan. The difference is remarkable—it's much quieter and performs better. Though it's not the cheapest option out there, I find that Noctua fans never disappoint, and this one is no exception. It’s a great choice for anyone looking for a high-quality case fan."

"I was building a new PC and needed something that would fit in a tight space. I decided to go with Noctua due to their great reputation. These fans fit perfectly with my AIO cooler and allowed enough clearance for my memory slots. They are rated even better than the original fans, and the noise level is impressively low. The only drawback is the price, but the performance is worth it."

"I needed to replace the board fan on my Ender 3 V3 SE, and these were the cheapest option available. They are super loud, probably about twice as loud as stock, but that’s fine for me since my printer is in a spare room. The airflow is great, and considering how often cheap fans fail, having 3 spares is worth it. I was down for 5 days waiting for these, but I’ll eventually get a quieter fan and hold onto these for backup."

"I replaced fans in a video switch that had gone bad, and these fans are so quiet in comparison. I got them for half the price of what the switch manufacturer charged. I bought additional ones to have on hand for future needs."

"We were searching for a low noise fan, and while this one claims 25 DBA, it actually measured at 55 DBA from one meter away. It does push 3 times the airflow compared to my failing fan, and it's just a little louder than my brand-new stock fan. For just $8 for 4 fans, it’s a solid deal."

“I can't fault this fan for being noisy since it doesn't claim to be a quiet fan. Even at low speeds, it moves a lot of air, but there’s a distinct whine that bothers me. If your server isn't in a noise-sensitive area, I highly recommend this.”

“I expected this fan to be loud at max speed, and it definitely is! I needed something to push a lot of air, and this fan really delivered. The noise is just what I anticipated, and I may add a fan speed controller to reduce the sound.”

“These fans exceeded my expectations. The noise and power curve are far better than many 80x38mm alternatives. I’ve been searching for a high static pressure solution in this size range, and these are the best I’ve found. I plan on ordering more soon!”

"I really appreciate the high quality performance of this product. It works flawlessly every time I use it."

"The durable materials used in this product give me confidence that it will last a long time."

"What I love most is how easy it is to use. I didn't even need to read the instructions!"

"I appreciate the well-designed plastic structure and good airflow. The low noise levels are a plus for me."

"I found it to be as described, but it can be a bit loud under load."

"Despite the hard starting at 1 Amp, it runs quieter than other server fans. I just need to set it to 9 Volts before increasing the speed."

"I use these USB fans to circulate air around my ham radio equipment when operating digital modes. They move a lot of air while remaining relatively quiet. The fan pair makes a small amount of noise, but it doesn't bother me. I have no complaints and would highly recommend this fan set."

"These fans are really nice to work with. I don't need a dedicated control system for them - they work perfectly with any USB device. In my case, they're running from a power strip with a USB-A port, and they work flawlessly. They are quite quiet, even behind the TV in a silent room. Since installing them, my router has improved significantly, and I've noticed fewer dropped internet connections. I've tried many fans before, but these have a premium feel and are perfect for everyday household needs."
