AI Verdict
This 240mm AIO with a Seventh Gen Asetek pump and 81 CFM fans is for users prioritizing RGB aesthetics and broad CPU compatibility.
This AIO is a strong fit for users building an RGB-centric PC, especially with an ASUS ROG motherboard, due to its Aura Sync compatibility and ROG aesthetic. The Seventh Gen Asetek pump and 81 CFM fans provide effective cooling for a wide range of Intel and AMD CPUs.
If you need more cooling capacity for extreme overclocking or higher-TDP CPUs, look for AIOs with a larger radiator (e.g., 360mm) and higher pump wattage.

Pros
- Seventh Gen Asetek pump delivers cooling with an operating range starting at 840 rpm.
- ROG-designed radiator fans generate 81 CFM airflow and 5.0 mmH2O static pressure for cooling.
- Individually addressable RGB lighting on the NCVM-coated pump cover and fans syncs with Aura Sync.
- Reinforced, sleeved tubing, 380mm in length, offers increased durability and flexible installation.
- Compatible with a wide range of Intel (LGA 1700, 1200, 115x, 1366, 2011, 2011-3, 2066) and AMD (AM4, TR4) sockets.
Cons
- AM5 socket compatibility requires a separate mounting kit, not included out of the box.
- Some users might mistakenly expect a custom display on the pump, which it does not feature.
- While minimal at low RPMs, fan noise levels can increase under heavy CPU loads.
- The 3-watt wattage for the pump is lower than some competing AIOs, potentially limiting extreme overclocking.
Dimension Scores
The Seventh Gen Asetek pump and ROG-designed fans deliver 81 CFM airflow and 5.0 mmH2O static pressure for cooling.
The Asetek pump starts at 840 rpm for minimal noise, and PWM control helps keep fan speeds low during light loads.
Features like reinforced, sleeved tubing and a copper cooling plate with micro-channels indicate a focus on durability and thermal efficiency.
The 380mm sleeved tubing offers flexibility for routing, but specific cable clips or integrated management features are not detailed.
Best For
- PC builders aiming for an RGB-synchronized aesthetic with ROG motherboards.
- Users needing a 240mm liquid cooling solution for Intel LGA1700 or AMD AM4/TR4 CPUs.
- Gaming setups where CPU temperatures need to be managed under load without excessive noise at idle.
Not Recommended For
- Users seeking an AIO with a customizable LCD screen on the pump.
- Budget-focused builds where a simpler, less expensive air cooler might suffice for non-overclocked CPUs.
Watch Out For
- AM5 users need to acquire a separate mounting kit for compatibility, as it's not bundled with the cooler.
- One Reddit user was misled into believing the pump had a custom display, noting it's just a flat surface for personal prints.
- The 3-watt pump wattage might be a limiting factor for users pushing extreme overclocks on high-TDP CPUs.

What Buyers Say
Users frequently highlight the cooler's visual appeal, especially how the ARGB lighting on the pump and fans integrates with ASUS ROG motherboards. Many report effective CPU temperature reduction, even under gaming loads. The installation process is often described as straightforward, which is a plus for new builders. However, some buyers were disappointed by the lack of a true customizable display on the pump, mistaking its flat surface for a screen. The need for a separate AM5 mounting kit also caused some frustration for users with newer AMD platforms.
“Dude, this thing looks SICK in my ROG build, the RGB is perfect. Keeps my 13700K chilly even when I'm hammering it, but seriously, why no AM5 bracket in the box? Had to wait for that to show up. Still, looks and cools awesome.”
Common Praise
- The ARGB lighting on the pump and fans looks fantastic and syncs well with other ROG components.
- CPU temperatures remain low during gaming and heavy workloads.
- Installation is easy and straightforward for most users.
- The pump operates quietly at lower CPU loads.
Common Complaints
- No AM5 mounting bracket included, requiring a separate purchase.
- The pump top is not a customizable display, despite some users expecting one.
- Fans can become audible at higher RPMs under sustained heavy loads.
Ownership Tips
- The NCVM-coated pump cover resists fingerprints better than glossy plastic.
- Aura Sync software can sometimes be finicky to set up initially for perfect RGB synchronization.
- The 380mm tubing length is generous enough for top or front mounting in most mid-tower cases.
- The pre-applied thermal paste is adequate for initial use, but enthusiasts might prefer their own.
Frequently Asked Questions
Is this cooler compatible with Intel's latest LGA 1700 socket?
Yes, the ASUS ROG Strix LC II 240 supports Intel LGA 1700 sockets, along with LGA 1200, 115x, 1366, 2011, 2011-3, and 2066.
Does this AIO come with an AM5 mounting bracket?
No, while compatible with AM5, the mounting bracket for AM5 is not included in the box and needs to be acquired separately.
How quiet is the pump?
The Seventh Gen Asetek pump is designed for minimal noise, with an operating range starting at 840 rpm. It uses PWM control to spin slower at idle for reduced noise.
Can I customize the RGB lighting?
Yes, the pump cover and fans feature individually addressable RGB lighting that is Aura Sync compatible, allowing for multi-color lighting effects.
What is the length of the tubing?
The reinforced, sleeved tubing is 380mm in length, providing flexibility for radiator installation in various chassis.
Buying Guide
When you're looking at an AIO liquid cooler like this, you're essentially getting a self-contained water cooling loop for your CPU. It's designed to pull heat away from your processor more efficiently than air coolers, especially for higher-end CPUs or if you plan on overclocking. The '240mm' refers to the radiator size, which means it uses two 120mm fans. This size is a common choice for balancing cooling performance and case compatibility.
Seventh Gen Asetek pump
Asetek is a major manufacturer of AIO pumps, and their 'Seventh Gen' indicates a refined design focusing on both cooling efficiency and reduced noise levels, especially at lower RPMs. Think of it like a car engine – newer generations are usually more efficient and quieter.
81 CFM / 5.0 mmH2O fans
CFM (Cubic Feet per Minute) measures how much air the fan moves, while mmH2O (millimeters of water) measures static pressure, which is how well the fan pushes air through restrictive spaces like a radiator. High numbers in both mean the fans can effectively cool the radiator, even if it's dense.
LGA 1700, AM4/TR4 support
This tells you which CPU sockets the cooler can physically mount to. If your CPU's socket isn't listed, it won't fit. LGA 1700 is for newer Intel CPUs, while AM4 and TR4 are for various AMD CPUs, including Ryzen and Threadripper.
Alternatives
If this 240mm AIO isn't enough, search for 360mm or 420mm AIOs for increased cooling capacity, or consider AIOs with higher pump wattage for extreme overclocking scenarios.
