Diamond aluminium heat sink

The SXDOOL H-617 is a compact 5 V cooler built from aluminium with a honeycomb fin structure. It measures 4.4 cm square and 1.15 cm thick, making it suited to tight spaces on small boards or modules. The unit includes a double-ball bearing fan that spins at high speed. A central 2.7 cm diameter mounting area sits 1 cm high for thermal contact.

Builders who accept audible fan noise

This cooler fits projects where a small 5 V active heatsink is needed and a slight increase in noise is acceptable. It is not for silent PC builds, noise-sensitive lab equipment, or sleeping-area media players where even low fan sound is unwanted. Users who cannot supply a 5 V header or solder point should look elsewhere. The fixed high-speed fan curve offers no PWM control for quiet idle operation.

Verify 5 V power and 4.4 cm clearance

Confirm the target device provides a stable 5 V supply capable of driving a small high-speed fan. Measure the available mounting area to ensure the 4.4 cm footprint and 1.15 cm height fit without fouling adjacent components. Check that the 2.7 cm central contact diameter aligns with the heat source. The fan can be removed and replaced with a quieter unit using adhesive if required.

Questions about this item

What power source do I need to run the 5 V fan on the H-617 cooler?

You need a 5 V DC supply such as a USB port, a 5 V pin header on a motherboard or a dedicated 5 V adapter that can deliver enough current for the double-ball high-speed fan.

Will the 4.4 cm square base and 2.7 cm centre cut-out clear the components I keep on my board?

The cooler measures 4.4 cm by 4.4 cm with a 2.7 cm diameter central opening 1 cm tall, so check that your existing parts fit inside that circle and that nothing taller than 1.15 cm sits under the fins.

How can I verify the H-617 is cooling properly once installed?

Monitor the temperature of the device you are cooling; a drop under load confirms the honeycomb aluminium sink and 5 V fan are moving heat away as intended.
