Geekworm Active Cooler H505 for Raspberry Pi 5 Heatsink with PWM Fan

Description

Product Overview

The Geekworm H505 active cooler is engineered specifically for the Raspberry Pi 5 series, covering models from 2GB to 16GB. Constructed from high‑grade aluminum, the heatsink provides a large surface area that rapidly absorbs heat generated by the CPU, GPU, and power management circuits. Coupled with a 30mm PWM blower fan, the system actively expels hot air from the board, creating a directed airflow path that maximizes cooling efficiency while maintaining a low acoustic profile.

Dimensions of the cooler measure 2.29 x 1.57 x 0.46 inches and weigh only 1.34 ounces, allowing it to fit snugly within most case designs without adding significant bulk. The included thermal pads are pre‑cut to match the major heat sources on the Pi, ensuring optimal contact and uniform heat transfer. The PWM fan operates between 0 and 12 V, offering precise speed control via software, which lets users balance cooling performance against noise levels according to their specific workload.

Manufactured by Geekworm, a brand recognized for reliable Raspberry Pi accessories, the H505 has earned a strong reputation reflected in its #24 ranking among heatsinks on Amazon and a 4.7‑star rating from over 80 verified customers. This product is a direct replacement for the stock passive cooling solution, delivering measurable temperature drops of up to 15 °C under sustained load, which translates into longer component lifespan and more consistent performance for demanding applications.

Usage

The H505 active cooler excels in environments where the Raspberry Pi 5 is expected to run for extended periods or handle intensive tasks such as media streaming, AI inference, or real‑time data acquisition. Its quiet 3007 fan makes it suitable for home theater PCs, digital signage, and classroom labs where audible distraction must be minimized. The cooler also fits well in industrial IoT gateways, where temperature stability is critical for sensor accuracy and network reliability.</n

Installation is straightforward: the heatsink attaches to the Pi’s board using the supplied mounting brackets, and the thermal pads are placed onto the processor, voltage regulator, and Ethernet controller. The fan connects to the Pi’s GPIO header or a dedicated fan header, and PWM control can be configured through common utilities like raspi-config or third‑party scripts. Users can adjust fan speed profiles to ramp up cooling during heavy workloads and reduce speed during idle periods, achieving an optimal balance between thermal performance and acoustic comfort.

Because the cooler is compact, it can be combined with protective cases, HATs, or additional modules without obstructing other ports. This makes it an ideal choice for hobbyists building custom robotics, edge‑computing devices, or portable development kits that require reliable thermal management in confined spaces.

FAQ

Does the H505 fit all Raspberry Pi 5 variants?

Yes, the cooler is compatible with the 2GB, 4GB, 8GB, and 16GB versions of the Raspberry Pi 5. The mounting brackets are designed to align with the standard board dimensions, and the thermal pads are sized to cover the processor, voltage regulator, and Ethernet controller on each model.

Can I control the fan speed manually?

The PWM fan can be controlled via software using the Raspberry Pi’s GPIO pins. Utilities such as fancontrol or custom Python scripts allow you to set fan speed thresholds based on temperature readings, giving you full control over cooling performance and noise levels.

Is the cooler compatible with existing cases?

Because the H505’s profile is low‑profile, it fits comfortably inside most standard Raspberry Pi 5 cases, including those with additional HATs or expansion boards. If you use a case with limited clearance, verify the internal height specifications to ensure sufficient space for the fan’s airflow path.

What warranty does Geekworm provide?

Geekworm offers a one‑year limited warranty covering manufacturing defects. If the cooler arrives damaged or fails due to a defect within the warranty period, you can contact support for a replacement or repair.

How does the active cooler compare to passive heatsinks?

Passive heatsinks rely solely on natural convection, which can be insufficient for high‑performance workloads. The H505’s active blower fan actively moves hot air away from the board, delivering significantly better temperature reduction, especially during sustained CPU or GPU usage, resulting in more stable performance and reduced risk of thermal throttling.
