HDPLEX H5 Fanless Computer Case Review

HDPLEX is widely known within the HTPC and audiophile communities for making premium, fanless computer cases. Can the second generation H5 build on the success of its predecessor?

Interior Components And Assembly

One of the major selling points of the H5 is that everything inside the case is designed to be passively cooled, and therefore silent. To accomplish this, the H5 comes with a specially designed cooling system that is built into the case. The system consists of a large, solid copper base, eight copper heat pipes, and the body of the case itself. The passive cooling system works by extracting heat from the CPU using the large copper base, which then transfers it to the case's left side panel using the eight copper heat pipes. The case's side panel then takes on the role of a giant heat sink and dissipates the heat into the surrounding environment. 

The passive cooling system is compatible with most mainstream Intel and AMD sockets including Intel LGA775 and 115X as well as AMD AM2+/AM3 and FM1/FM2/FM2+. The passive cooling system is also compatible with Intel's Skylake CPUs. Finally, the CPU cooling system is capable of passively cooling CPUs with TDPs up to 95W.

In addition to the passive CPU cooling system, HDPLEX also sells a separate passive cooling system for customers with discrete graphics cards. The GPU cooling system supports most mainstream cards with TDPs up to 95W

The Build

Even though users receive the H5 as nothing more than a large box full of parts, the process of assembling the H5 is actually pretty quick and straightforward. To make things even easier for the end user, the H5 comes with a 34-page instruction manual detailing every step of the assembly process. Today's assembly section will feature details on the normal assembly process for this case, using the case's passive CPU and GPU cooling systems.

The assembly process starts out by attaching the case's four metal feet, motherboard standoffs and left side panel to the bottom plate. From there, the copper CPU base plate is installed on the motherboard, and the motherboard is installed in the case. Thermal paste is then applied to the groves in the side of the case as well as on the copper CPU base plate and aluminum top plate. Each of the eight heat pipes are then inserted into their respective slots and are secured to the case by flat metal plates, and to the CPU base plate by an aluminum heat sink top that bolts to the top of the baseplate.

Once the CPU cooling system is installed, the case's right and rear side panels are installed. The graphics card is then installed using the supplied ribbon cable, and if it is being passively cooled, the GPU cooling system is installed using the same steps used in the CPU cooling system installation. Finally, the power supply and hard drives/SSDs are installed, and all necessary cable connections are made.

In case you were curious, here's what the inside of the H5 looks like when it's full of air-cooled parts. There really isn't much room for a CPU air-cooler inside of this case, but it's still possible to fit one in there if it's small enough.

Once the assembly of all internal components is completed, the top panel bolts on with six hex screws and the end-result looks something like this.
