Best fans for price to performance
I've been using Arctic Fans since I got into PC building.Even singles are substantially less expensive than the market leader, Noctua. These are quiet and powerful. The PST means these are daisy chained and therefore dont need a splitter to connect multiple fans to one header.

one of the best fans around
bought these for my NR200 (long time user of artic products) to place under the gpu, fantastic fans that are very quite except at 1000-1100 rpm, just avoid that range and they are near silent with great airflow, amazingly cheap compared to the competition, highly recommended, if you want a simple way of changing fan speeds just grab fan control from github.

Quiet, easy to install, comes with screws.
The media could not be loaded. It's quiet, easy to install, comes with screws. Comes with a 3 pin and 4 pin header cable. Easy to setup the speed-temperature in the BIOS. As you can see I've an older PC case which has upgraded CPU and GPU so I needed better cooling. The GTX 1080Ti uses 250-280 Watts, the i7-9700k CPU uses 80-120 Watts, so combined that's a lot of heating inside the case. I bought this 15mm thick fan to squeeze above the CPU cooler and provide it with fresh cool air. It's reduced CPU temperatures by at least 10-15°C when gaming. CPU now has idle of 30°C and under load it's 55-64°C.Adjusted the BIOS to spin the fan faster as the CPU heats up, so the computer is very quiet when not gaming.Easy to recommend.

A little help to the airflow
Thin version of the popular Arctic P12 PWM PST. Doesn't move much air but at least it does so quietly. Its motor may be a bit wobbly so the fan blades can hit a grille at full RPM if it's too tight against the fan.

Comes with radiator mounting screws
Great fan and performs slightly better than my old 25mm thickness ones. Slimmer profile is exactly what was needed in my Mini-ITX build, buying precious millimetres. Should clearly say that it comes with 4 normal fan mount screws AND 4 radiator (through) mount screws for the 15mm width profile. No need to try and source them separately!

Arctic fans are FANtastic
I have some of the thicker ones on the back of my Freezer 240, super powerful and very quiet at high rpm, got this one to fit under my rad as I can only fit a slim one there due to its reservoir. Very quiet and powerful like the others

As described.
Just what I needed for a cramped space in my diy pc build. Does the job.

Great fan
They’re slim which is what I needed the arctic freezer 2 is one thick rad and the original fans where to thick and wouldn’t allow me to actually sit the GPU in the pcie socket at all. Good air flow and pressure optimised. Temps remain very low on a 9900k very happy. Cheap fans that do the job, compared to other slim fans this hits the nail on the head
