- Dedicated DisplayPort interface allows the 3.5-inch 60Hz IPS panel to function natively as a secondary Windows display.
- RS II Unified Frame fan system eliminates daisy-chain clutter with a single direct 4-pin PWM motherboard connection.
- Quiet 20 dBA pump acoustic floor paired with high static pressure fans reaching up to 4.2 mm-H2O.
- Broad socket retention system supporting AMD AM4/AM5 and next-generation Intel LGA 1851/1954 platforms.
- Horizontal screen mounting on AMD platforms requires Bracket Revision 1, potentially requiring a support ticket if bundled with Bracket 2.
- Requires routing a dedicated auxiliary DisplayPort cable alongside motherboard wiring to power screen visuals.
- Unified dual-fan configuration requires verifying motherboard CPU_FAN header amperage limits.
Overview
Driving thermal dissipation through a high-static-pressure dual-fan assembly, the FlowDrive 2S pump circulates coolant across an expanded micro-fin copper cold plate into a 240 mm (9.45 in) aluminum heat exchanger while sustaining an acoustic floor of 20 dBA. Rather than relying on proprietary USB-based command hubs, the cooling subsystem routes video signaling for its 3.5 in (88.9 mm) 480×640 60Hz IPS panel directly over DisplayPort, enabling the integrated LCD to interface natively as an auxiliary monitor within Windows. Thermal exhaust is managed by a pair of RS II unified-frame fans employing magnetic dome bearings, delivering up to 73 CFM of airflow and 4.2 mm-H2O of static pressure across a 0 to 2,100 RPM operational band.
Corsair streamlines internal chassis integration by packaging the dual fans into a single rigid unified frame, terminating in a single motherboard-direct 4-pin PWM header. This architecture eliminates the cable clutter and failure points typical of multi-fan daisy chains, though builders must verify that their motherboard CPU fan header can comfortably accommodate the combined current draw of both fans. Coolant travels through 17.7 in (450 mm) black-sleeved low-permeation rubber tubing, providing ample length and flexibility for front- or top-mounted configurations across both legacy and modern sockets, extending to AMD AM4/AM5 and Intel LGA 1700, LGA 1851, and LGA 1954.
System telemetry and display personalization are governed by Corsair iCUE, which synchronizes performance metrics and graphics across the 60Hz screen without requiring secondary controller modules. However, physical integration presents an acknowledged hardware quirk on AMD platforms: achieving a proper horizontal LCD screen orientation requires a specific revision (Bracket 1), while units packaged with Bracket 2 necessitate a support ticket and replacement hardware from the vendor. Once mounted with the appropriate retention hardware, the assembly maintains dependable thermal transfer backed by a five-year warranty.
