AI Verdict
This 240mm AIO with a 2.1" IPS LCD screen and 20 dBA pump cools Intel LGA 1851/1700 and AMD AM5/AM4 CPUs for users prioritizing visual customization.
This 240mm AIO offers solid cooling for modern CPUs and a unique 2.1" IPS LCD screen for personalization. However, user reports of fan and pump noise, along with potential iCUE software quirks, mean it's not a universal recommendation for silence-focused builds.
If quiet operation under load is critical, look for AIOs with lower reported fan noise levels (e.g., below 30 dBA at max RPM) or larger radiator sizes (e.g., 360mm) for more thermal headroom at lower fan speeds.

Pros
- The 2.1" IPS LCD screen allows custom images and GIFs for personalization.
- The pump operates at a quiet 20 dBA.
- A convex cold plate with pre-applied thermal paste simplifies installation and maximizes CPU contact.
- Daisy-chained fan connections simplify cable management.
- RS120 fans utilize AirGuide technology and Magnetic Dome bearings for efficient cooling.
- It is compatible with Intel LGA 1851/1700 and AMD AM5/AM4 sockets.
Cons
- Fans can become loud, described as a "jet taking off" past 30% RPM by one user.
- The pump is audible to some users, despite the 20 dBA specification.
- iCUE software might not always recognize the cooler, requiring alternative lighting control.
- Corsair does not publish pump block dimensions, making fitment planning difficult for some builders.
Dimension Scores
The 240mm radiator, convex cold plate, and RS120 fans with AirGuide technology provide strong cooling for modern CPUs.
While the pump is rated at 20 dBA, user reports indicate both the pump and fans (36 dBA at max speed) can be audible, with fans becoming very loud at higher RPMs.
Constructed from plastic, metal, and glass, with Magnetic Dome bearings in the fans, suggesting durable components.
Daisy-chained fan connections and direct motherboard plug-in simplify wiring significantly.
Best For
- PC builders wanting a customizable aesthetic with CPU temperature monitoring via the 2.1" IPS LCD.
- Systems needing efficient cooling for modern Intel LGA 1851/1700 or AMD AM5/AM4 CPUs.
- Users prioritizing simplified fan wiring with daisy-chain connections.
- Builds where a white AIO cooler complements the overall aesthetic.
Not Recommended For
- Budget-focused builds where the LCD screen adds unnecessary cost.
- Users who prioritize absolute silence under heavy load, due to reported fan noise.
- Small form factor cases without clear pump block dimensions for fitment planning.
Watch Out For
- Fans generate significant noise, reaching "jet taking off" levels past 30% RPM for some users.
- The pump's 20 dBA rating doesn't prevent it from being audible to some users.
- iCUE software has been reported to not recognize Corsair coolers, forcing users to use alternative lighting control.
- Corsair does not publish pump block dimensions, making it difficult to confirm clearance in compact cases.

What Buyers Say
While the 2.1" IPS LCD screen offers unique customization for displaying temperatures or GIFs, some users report issues with the iCUE software not recognizing the cooler, forcing them to use alternative lighting control. The pump, despite its 20 dBA rating, is audible to some, and the RS120 fans can get quite loud, described as a "jet taking off" past 30% RPM. Installation is generally straightforward due to pre-applied thermal paste and daisy-chained fans, but the lack of published pump block dimensions can complicate planning for compact builds.
“Honestly, the screen is cool for my temps, but I wish the fans weren't so loud when my CPU actually gets hot, and iCUE sometimes just ignores it, which is annoying.”
Common Praise
- The 2.1" IPS LCD screen provides a customizable visual element.
- Pre-applied thermal paste and convex cold plate simplify installation.
- Daisy-chained fan connections make wiring less cluttered.
- Compatibility with a wide range of current Intel and AMD sockets.
- Effective cooling for CPUs like the 7800x3d.
Common Complaints
- iCUE software sometimes fails to recognize the cooler.
- Fans produce significant noise at higher RPMs.
- Pump is audible despite its low dBA rating.
- Corsair does not provide pump block dimensions.
Ownership Tips
- The 2.1" IPS LCD screen remains bright and clear for displaying system info or custom images.
- The daisy-chain fan connections genuinely reduce cable clutter inside the case.
- The pre-applied thermal paste holds up well, even after a few months of use.
- You might find yourself tweaking fan curves to balance noise and cooling performance, especially under load.
- The white aesthetic integrates cleanly into white-themed builds.

Buying Guide
When picking a CPU cooler, you're balancing how well it cools, how loud it gets, and how easy it is to install. For an AIO like this, the radiator size (240mm here) dictates its cooling capacity, while fan and pump noise levels directly impact your daily experience. The LCD screen is a bonus for aesthetics and quick system monitoring, but it's not about raw performance.
240mm AIO
This refers to the radiator size, meaning it has two 120mm fans. Larger radiators (like 360mm) generally offer more cooling potential or can run quieter at the same cooling level.
2.1" IPS LCD Screen
This is a small display on the pump head that lets you show CPU temperatures, custom images, or GIFs, adding a personalized touch to your build.
20 dBA Pump / 36 dBA Fans
These are noise ratings. The pump is designed to be quiet, but the fans, especially at their maximum 2,100 RPM, can generate noticeable noise (36 dBA is like a quiet conversation).
Daisy-Chain Connections
This means you can link the fans together and connect them to a single motherboard header, simplifying wiring and reducing cable mess.
Alternatives
If you need quieter operation under load, look for AIOs with larger radiators (e.g., 360mm) or those specifically marketed for ultra-low noise, often with lower max fan RPMs. If the LCD screen isn't a priority, consider AIOs without displays for potential cost savings.
