Test setup
By popular demand, I’m going for a closed system in the form of a PC specially assembled for igor’sLAB by MIFCOM(exemplary product link, not an affiliate) this time. The case used is really good, has enough internal volume and also an excellent airflow. The used AiO compact water cooling in the form of Be Quiet’s Silen Loop II visually matches the GeForce RTX 4090 FE and the RGB accents of the RAM and motherboard can either be set to plain white or turned off completely in case of doubt. When things get too colorful again.
The PC was assembled nice and neat by MIFCOM (I’m always like that with the cables) and can be purchased in this configuration (see below) exactly the same or modified at the dealer. It was simply important to me here to use a commercially available solution and not my extremely chilled lab hardware in the climate oasis. There is enough space between the side panel (glass) and the graphics card and the storage space of the XL case was not even close to being used. Thus, even all other RTX 4090s without AiO still have enough room to breathe. So that should fit. I also only need two fans in the front. Unfortunately, the side panel only really closes smoothly here with an adapter cable from CableMod, so I use that.
However, the measurement of the detailed power consumption and other, more in-depth things is done in the lab on two tracks using high-resolution oscilloscope technology (there are also various follow-ups!) and the self-created, MCU-based measurement setup for motherboards and graphics cards (pictures below) or NVIDIA’s PCAT. For this, of course, I use a redundant system, with the same components, because such measurements in the housing are rather difficult.
The audio measurements are done outside in my Chamber (room within a room).
I have also summarized the individual components of the test system in a table:
- 1 - Introduction, technical data and technology
- 2 - Test System and the igor'sLAB MIFCOM-PC
- 3 - Teardown: PCB and cooler
- 4 - Gaming Performance
- 5 - Power Consumption and load balancing
- 6 - Transients and PSU recommendation
- 7 - Temperatures, clock rates, fans and noise
- 8 - Efficiency. summary and conclusion
