Review: They Work Great but May Not Work With PWM--DC Mode is Still Very Good Result - I purchased a few packs of these as "performance filler fans." -- I like to use 140 mm case fans for my primary cooling duty but for rear exhaust and front "2nd duty" fans these really give a price to performance advantage. Actual fan speed I get: Approximately 690 > 1800 RPM in DC Mode. I first used these as "extras" in a new i7 2700K build. I used these as a quiet supplemental solution with somewhat high-speed capability to supply air to the bottom of my case while pulling some extra air out the back. The build I first used them in already has AIO pulling through the top and primary HPF fans so super high performance wasn't needed in the exhaust or the bottom of the case. That said the 1700 RPM these fans supply a very respectable airflow. USAGE: to supplement a Noctua High performance 140 mm and very high RPM Phantek T30-120 mm case fan in front of an AIO Cooled Corsair 4000D case "MSI i712700k build," also used as a rear exhaust fan. I chose these fans for the top speed per price and the fact they were supposedly PWM. The PWM does not work on my MSI motherboard, but they do work perfectly set to DC mode in the bios. PWM has the lowest speed of 1100 RPM. DC lowest speed 650>690 RPM. As long as you know how to switch mode from PWM to DC "as in my case" your golden. I put images of the low and top end speed I can get in DC mode from these fans on my MSI Z690 MB. This is much more respectable speed and very noticeable air flow behind the fan. These things are very silent until about 11500 RPM and have no excessive motor noise commonly associated with any fan over 1500 RPM. The noise is simple air flow. The sound of airflow is not a bad, it means your being cooled. In summary, I have no hesitation to create a full build around these fans. Impressively silent from 680 > 1200 RPM. Expected airflow noise past 1200 RPM.
Review: Recommended - Solid fans for a good price. They fit accurately, spin quietly, and cool thoroughly. Installed (six total ) in an ATX tower that runs 24/7 in 2020 (now 2025) and they're still spinning! Connectors and wires are solid, and look good in the case. Overall performance is great, adequately cooling a box with 6 spinning HDDs and 3 PCIe relay cards.

## Questions & Answers

**Q: Do the fans come with screws? Cause I dont have any??**
A: I received 8 screws...packed loose in the box with the fans.  It looked like an "open box" item, so definitely seems like a YMMV opportunity.

**Q: 4 pin connection?**
A: These have 2 connectors attached.  One is a 4pin molex passthrough (male/female).  The other is a 3 pin header connector (.1"/2.54mm)

**Q: do these need to use the molex power connector?**
A: Yes it is dual. It has a 4 and 3 pin connector, I'm using the motherboard (3pin), but I assume the molex (4pin) would work as well, without the control.

**Q: are these at the fasted speed connected to the molex?**
A: I want this answered too.  I believe you are asking if these fans run better with the molex connected, or the 4 pin, right?

### ⭐⭐⭐⭐ Quiet Cooling Power in a Value 3-Pack
*by E***S on August 26, 2025*

Quiet Cooling Power in a Value 3-Pack These 120mm upHere case fans turned out to be a great upgrade for my build. I installed all three right out of the box—one as an intake, two as exhaust—and immediately noticed how much better the airflow felt compared to my older stock fans. They move a solid amount of air without sounding like a jet engine, which is exactly what I was hoping for. The noise level is very low—just a steady hum that quickly fades into the background. The build quality is good for the price. The frame feels sturdy enough, and the blades spin smoothly. The black design is clean and doesn’t clash with anything inside the case, so if you’re not into RGB, these are a nice no-nonsense choice. Mounting was simple—screws lined up with my case holes and the fans went in without a fight. Things to keep in mind: these are 3-pin fans, so if your motherboard or controller is designed for 4-pin PWM control, you’ll only get voltage control for speed, not full PWM precision. For me, that wasn’t a deal breaker since my board can still adjust them, but it’s worth noting if you’re picky about fine-tuned fan curves. The cables are a reasonable length but not overly long, so good case cable management helps. Bottom line: A quiet, affordable, and effective 3-pack of fans that gets the cooling job done without fuss. If you’re looking to refresh your airflow without spending premium prices, these fans are an easy recommendation.
