I doubt these are PWM controlled so it's a pass...

Less than $4.50 per fan. Pretty good deal for a good brand with a good product. Lots of airflow, and reviews say they are almost silent. Uses 3-pin. 🤷

Great fans. Something to note is that they use less than 2 watts per fan (1.92), and they don't have the PST feature (another connector to let you connect fans to each other and then plug into the motherboard fan header), and they use a 3 pin connector. Most motherboards are fine with a 3 pin connector on the fan header, as they adapt from PWM (4 pin) to voltage control (3 pin) just fine.

Fan controllers are usually PWM only, and will supply 12 volts to all fans, meaning they will run at full speed.

If you want to install more fans than you have fan headers on your motherboard look for a cable that will let you connect multiple fans (3 pin or 4 pin are fine) together. Because these fans use less than 2 watts each, and most motherboard fan headers can output 1A (please check your specific motherboard!) you could connect all to one header. I'd suggest connecting no more than 3, in case your motherboard is limited to half an amp. You'll also be able to control the two groups independently if that matters to you.

These fans are fine, excellent value. If the above considerations seem annoying, you may want to look for Arctic fans with PWM and PST features. Those will use 4 pin connectors, support daisy chaining, and will be compatible with PWM fan controllers.

These are not PWM. 3 pin = set fan speed, 4 pin = pwm

I'd pay the extra $5 for the ARCTIC P12 Pro PST 5-pack. It has a 4-pin connector, and was updated to 7 fins and a stiffening ring, which increased the air-flow and reduced the noise compared to this model.

Edit: Looks like the Pro is OOS, but I'd still rather just wait for it to come back in stock.

I have a bunch of the PWM version. I had one vertically-mounted fan die a few months in. The rest of the vertically-mounted fans are still going 2.5 years in. The horizontally-mounted fans are another story though. I've had 3 of those fans already. It seems these fans just don't like being mounted that way. Arctic has not given me a hard time about replacing them under warranty, but the last time it did take them over 3 weeks to respond to the ticket.

It's 2026, don't buy fans that aren't 4-pin PWM

This is incorrect. 3 pin fans can have their fan speed controlled. You need to plug them directly in the motherboard (or to a fan splitter, not a hub). Motherboards can read RPM data on the third pin and reduce voltage to adjust fan speed.

I bought this exact same 5 pack from Microcenter years ago and used a 1 to 4 fan splitter to connect them to a single motherboard port. They pull like 2W per fan and most modem motherboards support up to 12W on a single port. I use these on builds where price is a major factor for my friend/family member and I've never had a complaint about noise.

120mm at 1800RPM is too loud for me.

If you're running fans full-speed for a rad or something, I'd get a molex or sata to 4-fan splitter. No sense running more current through the board if you don't have to.

Bought 140mm versions of these some time back for very cheap, and holy hell they are loud AF. Even used FanControl to slow them down and only got to tolerable levels when under 40%, unfortunately they shut off completely at much lower than that.
Do yourself a favor and get fans that don't have such high RPMs at stock settings
