EK-AIO Basic 240 (240mm AIO Liquid/EK Waterblocks Entry Model/PWM Pump and Fans) Review
The EK-AIO Basic 240 brings EK Waterblocks, a brand with a long-standing reputation in the custom liquid-cooling loop space, into the pre-built AIO market at an entry-level 240mm size. For builders who recognize EK specifically from the custom watercooling world, this offers a way to get an EK-branded pump and radiator without building a full custom loop.

Thermal Performance and TDP Rating
A 240mm radiator with dual 120mm PWM fans covers mainstream and moderately demanding CPU cooling needs, positioned as EK's accessible entry point rather than a flagship performance play within the broader AIO market.
Pump and Fan Design
The PWM pump and fans allow standard speed-curve integration with system software, consistent with modern AIO design conventions across the category.
Socket Compatibility
Support for AMD AM4/AM5 and Intel LGA1200/115X/2011/2066 is listed out of the box; LGA1700 is not on EK's listed socket support for this kit.
Comparison to Sibling Products
Against the Arctic Liquid Freezer III 240, covered elsewhere on this site, that cooler carries a more extensively tested value reputation and Arctic's distinctive integrated VRM fan feature, generally the stronger default recommendation at a similar price point for buyers without a specific brand preference. Against the Cooler Master MasterLiquid PL240 Flux, also covered elsewhere on this site, both occupy a similar entry-level 240mm tier from established, if not primarily AIO-focused, cooling brands.
Who This Cooler Is Actually For
Buyers who specifically want an EK-branded product, whether from custom-loop brand familiarity or ecosystem preference. This is EK's accessible entry into the pre-built AIO space for exactly this audience.
Compact cases needing a straightforward 240mm liquid cooling solution. Covers mainstream needs without requiring 360mm clearance.
Not for buyers specifically chasing the strongest value-per-dollar in this radiator size without a brand preference. The Arctic Liquid Freezer III 240, covered elsewhere on this site, carries the stronger independent testing reputation at a comparable price.
