A compact top-flow CPU air cooler from DeepCool — the UD551 — providing efficient heat dissipation with a large 136 mm fan, low noise operation, and customizable ARGB lighting. Ideal for AMD systems needing a balance between cooling, noise, and aesthetics.

Top-Flow Cooling Design with 136 mm Fan - The large top-mounted 136 mm PWM fan pushes air downward over the heatsink, cooling the CPU while also circulating air over surrounding components (VRM, RAM), helping maintain overall motherboard stability.

Quiet Operation (≤ 26.8 dB) - Fan operates at 500–1800 RPM, maintaining noise levels at or below 26.8 dB — making it suitable for quiet environments such as offices, bedrooms, or living-room PCs.

ARGB Ring Lighting & Motherboard Sync Support - Built-in addressable RGB (ARGB) LED ring lets you customize lighting (16.8 million colors) and sync with compatible motherboard lighting software — adding aesthetic flair without compromising cooling.

Compact Size & Easy Installation - With dimensions of 136 × 136 × 69 mm and net weight ~378 g, the cooler is compact enough for many mid-tower or small form-factor cases, and mounting is straightforward thanks to simple installation mechanism.
