ARCTICP14 Slim PWM PST - PC Fan, 140mm Case Fan, with PWM Sharing Technology (PST), Pressure-optimised, Quiet Motor, Computer, Extra Slim, 150–1800 RPM - Black

I love this fan. I put it in my 3D printed BeamCase SW in place of my CPU cooling fan, and it does a phenomenal job. It's very quiet and it cools really well. My temperatures dropped 15-20 degrees C vs. my stock Thermalright 120mm fan, while keeping noise levels whisper quiet, even at high speeds.

I upgraded my stock power supply to an SFF-L model and needed these slim fans instead of the stock ones. These do a sufficient job at cooling my radiator even though they are not technically design for it. I'm very happy that I was able to fit my larger power supply and these fans were available from Artic.

These are a must if you are building SFF. Simple, easy, stealthy and slim. Sound level is also acceptable. I would absolutely buy more if they made a reverse blade variant because the fan is so slim that on the non grate side the blade can rub on the mount location. This is problematic for my build in top exhaust spot.

Works fine but was a little too thick for my case.

the bad- they wobble -slow startup - blade is offset to one side ,not good for side intake blades can rub, not very good fans at all , the good - well they work - there cheap - they push more air than a 120, had to use washers to stop rubbing .

Great fan for small form factor builds that support 140mm.

I got a liquid freezer ii some time ago and while it’s been great, I can only use it by mount it one way, the front of the case. This was fine and kept the cpu very cool, but it increased gpu temps and limited the length of the gpu. Tried it in different orientations and recently bought a new case (not for this reason but still) and there was no luck, the rad was too thicc so the included fans wouldn’t fit due to it running into the motherboard. Fast forward to today and I was finally able to mount both the fans and the rad on top resulting in lower gpu temps granted with higher cpu temps, probably need to switch some fan speed profiles anyways so not too worried.Overall, really happy with these fans. Came with standard case screws and rad mounting screws which was perfect.I will say, the box it came in was incredibly tight fitting, it actually required me to tug on the cord it was so tight, with no packaging so I could assume the bad reviews of this arriving broken are from that.

I use the Arctic Freezer 280 in a nzxt h7, and it didn't fit up top due to the motherboard heatsink and colum in the case. Using these, it fits perfectly with some room to spare, and performance wasn't really all that affected with my oc'd 13700k. Temps maybe changed 1-2c, maybe? But nothing to worry about. They're also very quiet, even running at max speed. Fwiw, I also received the fan blades that are connected at the ends, they feel pretty durable and I haven't experienced any of the issues mentioned in other reviews. I'll update if I do, but in the meantime, I would recommend them if you need to fit a radiator in a tight area.
