PC case CORSAIR FRAME 4000D RS Midi Tower White — ATX, tempered glass, 3x120mm front fans, supports 360/240/140mm radiators

The CORSAIR FRAME 4000D is a modular mid-tower PC case designed for flexible builds and high airflow. It supports modern motherboards and next‑gen GPUs, offers multiple dedicated radiator locations and extensive fan mounting options, and includes accessories such as three RS120 PWM fans, a GPU anti‑sag stabilization arm, and a cable shroud for a tidy internal layout.

Advantages

The FRAME 4000D provides near‑limitless modular upgrade options, including replaceable front I/O panels and an upgradable motherboard tray. Its InfiniRail multi‑point steel fan mounting system lets you position fans precisely (up to 200mm at the front and 140mm at the roof). The new 3D Y‑pattern steel front panel improves airflow by up to 12% compared to traditional designs. The case supports up to two 360mm radiators and up to ten 120mm fans simultaneously, enabling powerful and quiet cooling when paired with included RS120 PWM fans featuring magnetic dome bearings and daisy‑chain connectors.

How to use

Install the motherboard and routing accessories, then choose fan and radiator positions using the InfiniRail sliding mounts to target airflow where needed. Fit the included RS120 PWM fans and daisy‑chain their connectors for simplified power and control. Mount radiators in the preferred combination of front, roof, or side locations up to two 360mm units. Use the cable shroud and internal routing channels to hide unused or long cables and attach the GPU Anti‑sag Stabilization Arm to support heavy graphics cards.

Recommendations

For optimal cooling and noise balance, use a combination of front intake and roof/side exhaust fans and consider installing up to two 360mm radiators for high‑performance liquid cooling. Ensure motherboard connector orientation is compatible if using reverse‑connector boards from Asus, MSI, or Gigabyte to maintain unobstructed airflow.
