Review: Excellent 240L water cooler - This 240L water cooler from Cooler Master is replacing and Enermax made 120L RGB water cooler than served me well for approx. 2 years, but the pump developed a rattling noise that was very disturbing, and CPU temps were reaching 100C. I realized that the water pump was going to leave me. This was for an Intel 8 core I7 9700 CPU. I removed the Enermax and replaced with the Intel air cooler that came with the CPU. The system became quiet and temps stabilized around 50C which are normal. I ordered ths Cooler master that had excellent reviews. Very nice and quality built. Instl instructions were very easy to follow. CAme with the Creo fuse thermal paste that was fairly easy to apply, without any applicator. Straight from the tube. Installed everything and presto. System works very quietly and the temp stabilized around 32 C. the 2 fans are actually very quiet. Very happy with this new water cooler. The only con is the RGB. It's suited for 3 pin RGB headers while my motherboard, an Asus Z390-P model, comes with a 4 pin RGB header that is unusable. But this is a minor con. I will look for a 4 pin to 3 pin adapter cable, then this will work with RGB lights. Not an issue. Review: Good price, Works well, and easy to install if you read the instructions. :) - This is a great unit and all you have to do is carefully read the instructions and you will have a great cooler at a very good price that should last for years. I bought the 120L to replace a 120m. There was nothing wrong with the 120m, but it was installed for 10 years and it is important to keep the CPU cool or it will crash. Cooler Master writes their coolers last up to 8 years, so I was pushing it. I had to remove the 120m to install the 120L, and thought it would be the same, so I did not read the instructions, which was a mistake, as it was not going the way I expected. So, I read the instructions for the 120L, which is only photos, but if you look at the photos it is easy to install. If you ignore the photos, it will not be easy to install. ## Features - Cool for R7|i5 : Patented Gen S Dual Chamber Pump enhances water pressure and optimizes flow directly to the CPU hotspot, for AMD R7 and Intel i5. - Minimalist Classic Design: Minimalist pump design gives a classic facelift while enhancing white lighting dispersion for optimal illumination. - Sickleflow 120: SickleFlow 120 fans deliver premium airflow with optimized PWM blades, while simplifying the installation. - Dynamic PWM Fan: A PWM 4-pin header allows adjustable fan speeds from 650 to 1,750 RPM, to balance noise and airflow - Simplify Brackets: Redesigned brackets simplify installation on AM5 and LGA 1851|1700 platforms. - All Style, No Colors: Sleek all-black design, perfect for those seeking a stealthy, minimalist finish ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0CDF9343N | | Best Sellers Rank | #32 in Water Cooling Systems | | Brand | Cooler Master | | Brand Name | Cooler Master | | Compatible Devices | Desktop | | Cooling Method | Liquid | | Customer Reviews | 4.3 out of 5 stars 639 Reviews | | Included Components | ML 120L Core, CryoFuze Thermal Paste, Install Kits, Manual | | Item Dimensions L x W x H | 6.2"L x 4.7"W x 1.1"H | | Item Weight | 2.8 Pounds | | Manufacturer | Cooler Master | | Material Type | Aluminum, Copper, Plastic | | Maximum Rotational Speed | 1800 RPM | | Model | MLW-D12M-A17PK-R1 | | Noise Level | 12 Decibels | | Number of Items | 1 | | Part Number | MLW-D12M-A17PK-R1 | | Power Connector Type | 4-Pin | | Product Dimensions | 6.2"L x 4.7"W x 1.1"H | | UPC | 884102111037 | | Unit Count | 1.0 Count | | Voltage | 12 Volts | | Warranty Description | 3 Years | | Wattage | 12 watts | ## Product Details - **Brand:** Cooler Master - **Compatible Devices:** Desktop - **Cooling Method:** Liquid - **Material:** Aluminum, Copper, Plastic - **Maximum Rotational Speed:** 1800 RPM - **Noise Level:** 12 Decibels - **Power Connector Type:** 4-Pin - **Product Dimensions:** 6.2"L x 4.7"W x 1.1"H - **Voltage:** 12 Volts - **Wattage:** 12 watts ## Images ![Cooler Master 120L Core AIO CPU Liquid Cooler – 120mm Radiator, Patented Gen S Dual Chamber Pump, PWM Fan, White LED Pump Lighting, High Performance Cooling, AMD AM5/AM4 & Intel LGA1851/1700 - Image 1](https://m.media-amazon.com/images/I/41y0UD6cWtL.jpg) ![Cooler Master 120L Core AIO CPU Liquid Cooler – 120mm Radiator, Patented Gen S Dual Chamber Pump, PWM Fan, White LED Pump Lighting, High Performance Cooling, AMD AM5/AM4 & Intel LGA1851/1700 - Image 2](https://m.media-amazon.com/images/I/71tBl7omkDL.jpg) ![Cooler Master 120L Core AIO CPU Liquid Cooler – 120mm Radiator, Patented Gen S Dual Chamber Pump, PWM Fan, White LED Pump Lighting, High Performance Cooling, AMD AM5/AM4 & Intel LGA1851/1700 - Image 3](https://m.media-amazon.com/images/I/71+aqrj7CIL.jpg) ![Cooler Master 120L Core AIO CPU Liquid Cooler – 120mm Radiator, Patented Gen S Dual Chamber Pump, PWM Fan, White LED Pump Lighting, High Performance Cooling, AMD AM5/AM4 & Intel LGA1851/1700 - Image 4](https://m.media-amazon.com/images/I/719BtZdbtzL.jpg) ![Cooler Master 120L Core AIO CPU Liquid Cooler – 120mm Radiator, Patented Gen S Dual Chamber Pump, PWM Fan, White LED Pump Lighting, High Performance Cooling, AMD AM5/AM4 & Intel LGA1851/1700 - Image 5](https://m.media-amazon.com/images/I/716SOCAEYxL.jpg) ## Available Options This product comes in different **Style** options. ## Questions & Answers **Q: Does it come with AM4 cooling bracket mounts or do I have to purchase them separately?** A: It’s like the Wraith cooler hinges.

It's been 4 years so far since installation and no issues or loss in cooling efficiency. I ran the computer overclocked around 60c-99c for 2 of those years..... Years later this newer model replaced it. Different fan and I'm sure different pump design/motor. The pump face design is practically identical. Installation is a breeze, and it looks like it belongs in my build. This is the BEST budget AIO water cooler. I would not recommend anyone go lower than this brand's quality for aio's because it is a liability. I've herd too many horror stories about cheap aio's leaking, bursting, or random pump fails all within a year. I would be devastated to came back to a wet ruined PC because I cut cheap on my aio. Fan n' heatsink is too loud, and a full-blown water-cooling system is too much maintenance. This device fall's perfectly in-between and the fact the previous version of this model is still running perfect in spite of being run at near max operating temps for extended periods of time and it being well past its life expectancy without warranty voiding maintenance being needed. I always keep power to pump at 50%-65%. Anything higher does not improve cooling and raises operating sound, and if it does cool better, it's by 1 degree. ## Frequently Bought Together - Cooler Master 120L Core Close-Loop AIO Liquid Cooler, R7|i5 Gen S Dual Chamber Pump, 120mm PWM, 120mm Radiator, White Lighting, AMD Ryzen AM5|4, Intel LGA 1851|1700 Platform - ARCTIC MX-4 (4 g) - Premium Performance Thermal Paste for All Processors (CPU, GPU - PC), Very high Thermal Conductivity, Long Durability, Safe Application, Non-Conductive - CORSAIR VENGEANCE LPX DDR4 RAM 32GB (2x16GB) 3200MHz CL16-20-20-38 1.35V Intel AMD Desktop Computer Memory - Black (CMK32GX4M2E3200C16) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/549617933-cooler-master-120l-core-aio-cpu-liquid-cooler-120mm-radiator](https://www.desertcart.jp/products/549617933-cooler-master-120l-core-aio-cpu-liquid-cooler-120mm-radiator) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-05-09*
