The AE240 V3 pairs a fourth-generation pump head with a 240mm black aluminum fin radiator and two 120mm ARGB fans (TL-C12B-S V2). Each fan spins at roughly 1500 RPM +/-10% and pushes up to 66.17 CFM at a noise level no higher than 25.6 dBA, so the pair can move meaningful air without dominating a quiet room. The pump itself turns at up to 2800 RPM +/-10% and carries a service life of 40,000 hours.

• 240mm radiator with protective mesh-wrapped tubing
• Dual 4-pin PWM fans that scale speed with CPU temperature
• 5V 3-pin ARGB header for lighting sync

Because both airflow and pump speed track CPU load automatically, noise stays low at idle and ramps only when the chip actually needs it.

The AE240 V3 mounting kit covers a wide span of current and recent platforms: AMD AM4 and AM5, plus Intel LGA1150, 1151, 1200, 1700, and 1851. That range means the cooler can move with a builder from an older Intel or AMD board to a newer one without buying a new cooling bracket, as long as the radiator size fits the case.

• Compatible with the two most recent AMD desktop sockets
• Covers five generations of Intel LGA sockets
• Standard 4-pin PWM and 5V 3-pin ARGB headers for motherboard control

Before installing, confirm the case has enough clearance for a 240mm radiator and dual 120mm fans in the front or top mount, since socket compatibility alone does not guarantee case fitment.

Pump head dimensions of 4.72"L x 0.98"W x 4.72"H keep the block itself compact, but the radiator and dual-fan assembly need real estate elsewhere in the case. Builders upgrading from air cooling should plan the radiator mount first, since 240mm units typically require a case rated for at least a 240mm front or top radiator with fan clearance.

• Octagonal pump head with an ARGB halo ring under the logo
• Aluminum fin stack paired with a mesh-protected water pipe for durability
• Fans and pump both draw ARGB sync from a shared motherboard header

Because the radiator and fans are matched to this specific pump, mixing in different third-party fans is possible but may change the noise and airflow figures listed above.

• The EPDM seal material is rated for strengthened, anti-leaking performance across all supported socket mounts

Because socket hardware differs between AMD and Intel mounting kits, confirming the correct bracket is included for the target CPU socket before installation avoids a mismatched mount.

RGB lighting runs through the pump head and the SickleFlow 120 ARGB fan, giving fully customizable lighting effects rather than a fixed static color.

• Lighting and fan speed are typically controlled through a motherboard's ARGB header or a bundled controller, depending on the build
• The EPDM tubing material is chosen specifically to resist leaks over years of use compared with standard rubber tubing
• Installation follows a standard AIO mounting process: bracket, pump, radiator, and fan, in that order, on the selected socket

Builders assembling a first liquid-cooled system should set aside time for radiator placement and cable routing, since AIO installation takes longer than a simple air cooler swap.
