15mm Thick Brushed Aluminum Faceplate

Brushed aluminum faceplate cost 3X of a sand blast faceplate.
Heavy Duty 1kg Copper Base


It is a crime to use aluminum base as the contact surface between CPU and heatpipe in a passive system. Copper thermal conductivity is 2X of aluminum.

HDPLEX H5 Chassis CPU Compatibility


HDPLEX newly designed CPU heatsink system supports latest Intel LGA 1700 socket for Alder Lake, LGA 1200 for Comet/Rocket Lake, and previous Intel LGA 115x socket with TDP upto 125W. It also supports latest AMD AM5 Socket, Ryzen CPU with AM4 socket with 125W TDP.

Due to new copper block has long base design, Intel CPU with vertical socket layout which is rare might not be compatible as long base could conflict with capacitors on the narrow side of the vertical CPU socket.

H5 Support Horizontal CPU Socket



Motherboard List NOT supported by H5 CPU heatsink System (Update Nov 8th 2021):

Gigabyte B560M Aorus Pro

HDPLEX CPU heatsink system will also support Intel Xeon LGA 3647 socket both square ILM and long ILM with additional racks. The rack set for Intel LGA 3647 Xeon CPU will be available for purchase in the future. It will enable to you install ASUS C621E Sage Workstation Motherboard inside H5 for full passive operation.





Internal Power Supply Options for HDPLEX H5 Fanless HTPC Chassis


HDPLEX H5 fanless HTPC chassis takes a bigger step forward and supports rich variety of internal power supply options including ATX/SFX/FlexATX power supplies.

We have developed a multipurpose rack to support internal mounting of ATX,SFX,Flex form factor power supply. A 45cm length AC extension cord with 90 degree angle IEC C14 connector is also included.

H5 supports soon-to-be-released HDPLEX passive GaN 250W ATX PSU and HDPLEX GaN 500W ATX PSU. These two HDPLEX GaN PSU can achieve >90% efficiency.

Linear Power Supply Options for HDPLEX H5 Fanless HTPC Chassis


HDPLEX H5 fanless HTPC chassis is designed together with HDPLEX 500W ATX linear power supply to achieve the best CAPS platform targeting at computer audio customers.

To eliminate extra components in the power delivery chain, HDPLEX have developed ATX modular bridge input board to enable HDPLEX 500W ATX linear power supply directly connecting to motherboard and HDD. No more DC-ATX converter needed.

HDPLEX H5 also supportS HDPLEX 300W linear power supply + 400W HiFi DC-ATX converter for low power systems.

External Power Supply Options for HDPLEX H5 Fanless HTPC Chassis


HDPLEX H5 fanless computer chassis inherits the versatile power adapter plate from previous generation and supports self-lock 7.4*5.0 DC connector popular on 19V laptop adapters and used by HDPLEX 200W/500W DC-ATX converters, and C14 AC/IEC connector.

The HDPLEX ATX modular bridge input board designed for 500W ATX linear PSU also creates an interesting possibility in which user could place a standard ATX modular power supply outside the H5 case. This scenario has two advantages: removes a major heat source inside the case and supports any size motherboard for H5 fanless HTPC chassis.
