Plug in Computer Fan, 12v Fan with AC to DC Power Adpater

This fan is a perfect solution for keeping my electronic equipment cool. I use it to cool an amplifier, and it has lowered the temperature noticeably. The best feature is the speed controller: on the lowest setting, it's practically inaudible and still moves enough air, and if I need maximum power, it responds wonderfully. The build quality feels solid, and it's very easy to install—just plug it in and you're good to go. The included rubber feet are a great touch to prevent vibrations.

Fan works great and has good airflow. The speed controller allows perfect balance of air flow and noise level. I have the fan set where it is nearly quiet with good air flow.

so, I picked up a really nice wine fridge for free.. the only problem was the temp differences between the back of the fridge and the front of the fridge, (a design flaw, I'm thinkin. the temp difference was +20°F from backto front) I figured what it needed was some air circulation to fix the problem and I was 100% correct. (I usually am 😃) this fan is perfect because of the low speed it can run at. now I have a nice wine fridge that won't freeze the bottle in back and have lukewarm bottles in the front!

It is doing exactly what I wanted it to do! Great product.

This fan is perfect to keep my modem cool - a genuine solution for my T-Mobile rural Internet problem. It runs 24-7 without any problems thus far. That being said, it would be good to have had assembly instructions. I assembled the first fan I received and returned it because it didn't work. When I began assembling the replacement, I realized that I'd attached the fan guards backwards so that they kept the blade from moving on the first fan (pilot error). I would not have returned the first fan had I known how to properly assemble it in the first place.

The size is absolutely perfect, and build quality is exceptional! First fan has been running round the clock for a month, it is consistent with power and air movement ! It was easy to use and setup, the fan guard is well made and slim to keep the overall width small. The low noise level is absolutely phenomenal! Through low to high, it emits low noise and moves air well! The rubber stoppers help keep vibration down and allow it to be rested directly on what you want to cool or move air from! I purchased the first one to move air and remove humidity from my Dubia feeder colony. The second I got to remove humidity and circulate air in my Bearded Dragon enclosure. Really impressed by the quality and use of this fan.

Very cool (no pun intended) product. It does the job and the speed adjustment can be set so low you can't hear it or feel an annoying breeze if it's nearby. Some assembly required. Lay out the parts first, or you'll be frustrated, especially with the fan grills, which must be installed right side up so the fan doesn't hit them.

Power supply went dead after a couple hours. Unfortunately I did not get to my project right away and missed the 30 day return window by a few days.

I’ve been using the Qirssyn 120mm AC Powered Variable Speed Fan to cool down my Mini PC for nearly 4 years, and I’m genuinely amazed at how well it continues to perform. It’s quiet, powerful, and reliable, with zero issues since the day I installed it. The variable speed control is a great feature that allows me to adjust airflow as needed, and I used at lower settings, so the noise level remains impressively low. It’s been running almost constantly, and I can’t help but wonder—why don’t more products last like this anymore? If you’re looking for a durable, effective cooling fan for your PC, modem, AV cabinet, or other electronics, this is one of those rare purchases that truly stands the test of time. I highly recommend this without hesitation.

Buen producto de buena calidad y a un excelente precio, llegó rapidicimo recomiendo el producto y al vendedor

Product arrived in good condition and in time. It works perfectly as described.

fan in my RV gave up the ghost. so Installed this unit to compensate and its better than the original by far. too bad it wasn't actual 12v powered bit through a transformer plug. but it works under shore power great.

Use to keep xbox cooler. Works well.
