be quiet! Pure Loop 3 LX

A 240mm AIO liquid cooler rated to dissipate 250W. Noise is specced at 15.5 dBA; socket compatibility spans AM5, AM4, LGA1700. That rating covers flagship parts like a 14900K or 9950X under sustained load. Confirm your case has a 240mm mount before checkout.

Expect to pay around $139.50, which lands it among high-end options. Drop it into the PlanMyPC builder to check compatibility with the rest of your parts and compare current CPU cooler prices across retailers. Warranty coverage follows be quiet!'s standard policy — confirm regional terms on the listing.
