ARCTICP12 Slim PWM PST (3 Pack) - PC Fans, 120mm Case Fan with PWM Sharing Technology (PST), Pressure-optimised, Quiet Motor, Computer, Extra Slim, 300–2100 RPM - Black

From a sheer performance perspective, and I'm talking pushing the most air through your case or into a heatsink, and doing so quietly, these fans are tough to beat. Considering they're only 15mm thick, I put them into my own best-of-class category.But while they do work great, they are on the flimsy side. I'll give you an example. After looking up the stats and reading some reviews, I decided to replace a competitor fan (name begins with 'Noc') with the P12 Slim in a sub-5 liter mini-itx case.I found the P12 to have slightly better performance by 2-3 degrees C in my case overall, with the noise the same as the Noc, at less than half the price. Only, when I first closed the case, the P12 wobbled at slow speeds, making an obvious noise along with it at startup and shutdown. This lasted for about 3 startups/shutdowns and just went away. I checked cables and all were clear, so it had to be coming from the fan. Considering its the same size as the other fan, which had no weird noise issues, I just felt the word flimsy came to mind. Maybe it twisted slightly to fit or something? I couldn't tell by looking. I'm not going to take a star off for this, but just be aware. I would have returned it if things didn't settle down.But it did, and it's been great, and mostly quiet, as the primary cooling fan for a Ryzen 9 7945HS. I'm not undervolting, and yet my temps are stable and well under 80C in normal use with temporary spikes up to 88C max. For the performance and value for the money, this is one of the best fans on the market at the 15mm height size.

My wife's new PC case couldn't fit standard fans in the front so once again I went with Arctic. Price for performance is absolutely the best. They hooked up and fit in her case fantastically. Definitely helps keep the temps down.

Fits my matx build with a tuf rx 9070 oc, mag mortar b650m mobo and asus ap201 case. Had the F12 pwm pst fans but they were too thick and was touching the GPU. These were a little more than half the thickness of the regular case fans. Works well, very good.

Works as expected and runs quite.

These fans are good if you need some air flow, but are limited by space. If you can fit 20 or 30mm fans, use those instead for much better airflow. That being said, if you need some fans and are limited by space these are a good option. They aren't the best for moving large amounts of air but they will create airflow.I'm using them in a SFF build to move a little bit of air over a thin radiator that compliments a regular 25mm radiator. So far they have helped bring my temps down by about 10C. Which is all that I was looking for. With just the one 240 radiator I was seeing temps get up to the high 70s and I wanted to bring them down. After some research I found that I could squeeze a thin 240 radiator and a set of these fans between the gpu and the side of the case. It's not optimal, and the fans are about 1mm from the gpu waterblock, but it's just enough to allow a little bit of airflow.

The small size is great for itx builds, and it wasn't loud. Was really impressed with this as it was part of a solution to help a problem with a build.My daughter has a small itx machine (super small case) where I upgraded her video card from a low power NVidia 50 series to a 70series and there was some airflow issues. I couldn't move the top fan down to the exhaust because of the clearance of a standard fan wouldn't fit over the heatsink on the machine. This one came in clutch though and the extra PWM sharing cable made doing wiring super easy, mostly with the limited fan headers on the ITX board.The fan worked fine for me. They aren't Noctua's, but it did work without issues for me.

Thin and pushes air well.

Even though a slim fan, cooled my PC down quite a bit as a 4th exhaust fan
