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.

This three pack was an amazing upgrade to the thermal status of my system. Installed seamlessly with either the long screws into the case or short screws into the fans. System integrated them into the fan control sub-system to provide RPMs on demand. Very minimal increase in noise considering went from three to six fans with this addition.

These fans seems to move a good amount of air through my pc and are fairly quiet. Especially after tuning the fan curve. Solid choose for affordable fans that are not too noisy

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

I used 2 of these for a deshroud mod of a msi 6700xt mech 2 that was getting way to hot with tj temps hitting 110 emedietly under any load, I also repasted the core and put new thermal pads on everywhere, I also needed a set of gpu pwm fan header to 4pin fan header adapter, now I'm not directly put hate on the 6700xt this heat issue was entirely my fault I had put this already hot running card into the wierd mounting position of an h1 v1 Rev1.0(I replaced the fire starter pcie risser and destroyed the old one so no worrys) and that case had the gpu verticle long ways with the gpu io down so the whole heat threw the channel design of most high end gpus with "heat to the back to the io" simply is turned on its head in this case BUT these slim fans fit perfectly and altho i do still get high junction temps these fans can spin at full speed and there whisper quiet unlike the ones from msi which were the only things I could hear in the entire home office...unexceptable...but these bairly fit into the space between the mesh filter and the deshrouded heatsink of my gpu and they don't make any noise at all and they do infact keep the regular temps down a bit so that's a double win in my book, I can sustain full load on the gpu without throttling so that's a successfull deshroud mod in my opinion and for the cost..ya I like this build now with its 128gb of ddr4 4000mhz and 5800x3d it has evolved to be a very nice linux dev and gaming system for me...

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.

I got two of these ultra slim fans because my case don't have a lot of room. There quiet and push quite a bit of air. I did although had to modify one of the fans mounting holes because it didn't clear my ram locking tab. But other then that, there VERY reasonably priced. An not to mention, i love the sleek black look. Im not an RGB fella so the black look is VERY clean.

Hardly any noise, fits perfectly between my gpu and case. Daisy chaining makes great use of limited fan headers on my itx motherboard.
