Thermalright TL-G12B: Black 120mm Computer Chassis Fan with 1500 RPM maximum speed and PWM control. This 4 pin fan uses a hydraulic bearing for quiet operation at just 23.6 decibels. It delivers strong airflow of 62.6 CFM, making it suitable for cooling PC cases or radiators.
About Thermalright TL-G12B
The Thermalright TL-G12B moves air with serious purpose thanks to its clever blade design. You get a focused airstream of 62.6 CFM with a strong 1.78 mmH2O pressure rating. This combination means the fan can push air through tight spaces like radiator fins or past hard drives without losing power. Seven specially shaped blades work together to direct the air exactly where your computer needs it most.
Noise is kept in check even when the fan is working hard. The hydraulic bearing uses a lubricant film to let the blades spin smoothly without grinding sounds. You will only hear about 23.6 decibels at full speed, which is quieter than a typical library. This bearing also lasts longer because it resists wear and never needs oiling or other maintenance from you.
You get full control over how fast this fan spins using the 4 pin PWM connector. Plug it into your motherboard, and it will listen to temperature signals automatically. During light web browsing or office work, the fan slows to near silence. When you launch a heavy game or start rendering video, it ramps up to 1500 RPM to pull heat away fast. This automatic adjustment helps prevent your computer from slowing down due to overheating.
The physical build of this fan makes installation straightforward and secure. It measures the standard 120mm by 120mm by 25mm, so it fits into almost any case fan slot without issues. The included 55 centimeter cable gives you plenty of slack for routing, and you can connect multiple fans in a chain. Soft silicone pads on each corner stop vibrations from traveling into your computer case, keeping everything solid and rattle free.Thermalright TL-G12B: Black 120mm Computer Chassis Fan with 1500 RPM maximum speed and PWM control.

Reviews Thermalright TL-G12B
Really impressed with how quiet this fan runs even at full speed. I have it pulling air through a thick radiator and it still pushes plenty of air. The cable is long enough to reach my motherboard header easily.
Got two of these for my gaming rig and they keep everything cool under load. The rubber corners really help with vibration since I barely hear any hum from my case. One small thing is that I wish they came in white to match my build.
After trying a few cheap fans that got noisy after a month, this one feels solid and well made. The PWM control works perfectly with my motherboard software. I love that I can daisy chain multiple units to keep my wiring clean.
