Optimized Low Noise Operation: Engineered with efficient fan blades and fluid dynamic bearings to reduce vibration and maintain consistent airflow with minimal noise output.
How It Works
The ARCTIC Liquid Freezer II 420 uses a closed-loop liquid cooling system to transfer heat away from the CPU. The water block absorbs processor heat and circulates coolant through tubes to the large 420mm radiator. Three PWM-controlled 140mm fans push air through the radiator fins to dissipate heat efficiently. The pump and fan speeds automatically adjust depending on system temperature for optimized cooling and quieter operation. An additional VRM fan helps cool nearby motherboard components for enhanced overall stability. This setup improves thermal management during gaming, rendering, and heavy multitasking workloads.

Great Socks.
Color: (002) Black / Black / Halo Gray, Size: Large
These are awesome and have become my favorite socks to have for everyday wear. I have since bought the hightop version as well and there are just as equally great. They fit almost like compression socks. Color does fade a bit after repeated washing but not enough to make a big difference in appearance. They have lasted for a long time and still going. They have lots of cushion which makes it very comfortable to wear.

Great Socks
Color: (001) Black / Black / Castlerock, Size: Large
I keep ordering these over and over again. They fit well, and are soft and comfortable. My feet don't sweat like crazy while wearing them. The cupped heel makes them fit even better. They hold up to everything from everyday use to active lifestyles.

Good sock but thick
Color: (001) Black / Black / Castlerock, Size: Small
These Under Armour socks are high quality and definitely durable, with great cushioning and a solid fit that stays in place throughout the day. The material feels supportive and they hold up well after multiple washes without losing shape.
My only minor downside is that they’re thicker than I expected. They feel more like a heavy-duty training sock, which is great for colder weather or intense workouts, but a bit bulky for everyday sneakers or warmer days.
That said, the quality is excellent, and if you prefer a thicker, more cushioned sock, these are perfect. Just something to be aware of depending on how you plan to use them.
