Test setup
I already wrote on the first page that the test system still had to be changed. An overclocked and slightly undervolted AMD Ryzen 9800X3D is used on an MSI MAG X870E Carbon WiFi with 2x 16 GB T-Force Delta RGB DDR5 6000 (32 GB kit) @CL30 as well as a TB MSI Spatium M480 Pro and an M580 4TB. The whole thing is powered by a Be Quiet! Dark Power Pro 13 1600 Watt. A semi-custom water cooler from Alphacool in the form of the Eiswolf Extreme keeps the CPU cool.
I have been using an Optris Pi640 for the heat flow analyses and infrared images / radiometric videos for the non-contact measurements for years and because I had to change the system, I am using the “old” T70 benchtable from Lian Li with special film and cover), which I can also close like a PC case. The Pi640 is an industrial camera with interchangeable lenses, various additional parts and functional software. With a full 640 x 480 measuring pixels, the bolometer for capturing thermal radiation is already as large as a normal VGA camera, which is interpolated into the image for optical enhancement in many cheaper devices. Not much more is currently possible. The videos are recorded at up to 30 FPS (Hz), which is also in a class of its own.
The Keyence VHX-7000 system with coupled AE-300 from my own laboratory is a versatile 3D profilometer and the powerful microscope (max. x2000) can also be used perfectly for such investigations with its HDR function, automated lighting scenarios and huge depth of field. It can also be used for material analysis, for which I don’t have to use an expensive SEM EDX. Vacuum? I no longer need it and it saves a lot of time. As long as you know what you’re getting into and what the limits of the method you’re using are, it works really well. That’s exactly what we need today.
I test the heat conducting materials with my TIMA5 to real industry standards. Here I also have the further links for you:

 Here you can find out why effective thermal conductivity and bulk thermal conductivity can be completely different in practice, what role the contact resistance between the surfaces and the paste plays and how thermal paste can be measured precisely. There is also a detailed description of the equipment, the methodology and the error tolerances. |
 You will learn how laser-induced plasma spectroscopy works and the advantages and limitations of the measurements. There is also high-resolution digital microscopy and analysis of particle sizes. This information is also used to estimate the long-term stability of a paste. |
However, the measurement of detailed power consumption and other, more in-depth things is carried out in the lab using two different methods: high-resolution oscilloscope technology and the MCU-based measurement setup I created myself for motherboards and graphics cards (pictures below) and NVIDIA’s PCAT. Of course, I use a redundant system with the same components because such measurements are rather difficult in the case.
The audio measurements are taken outside in my chamber (room within a room).
I have also summarized the individual components of the test system in a table:
