Speedy custom desktop with 4x RTX 2080 Ti cards rips apart OctaneBench without going over 75 °C
Sometimes one high-end desktop graphics card just isn’t enough, and sometimes two or three cards aren't enough either. One PC builder decided that he required four GeForce RTX 2080 Ti graphics cards neatly jammed together for his customized desktop computer. The choice is understandable to a degree, as apparently the device is used for Octane rendering, but unsurprisingly there have been concerns raised about the potential for massive overheating.
However, the builder claims that the powerful and compact build, which as can be seen in the image also packs in an AMD Wraith Ripper cooler for the CPU, has managed to score over an incredible 3,500 points on OctaneBench while keeping its cool. Fortunately, the benchmark offers a comparison tool to help put this score into perspective: Systems with 1x RTX 2080 Ti have scored an average of 303 points, and builds with 8x RTX 2080 Ti cards have scored an average of 2,437.99 points.
To keep the desktop from melting down, the builder has utilized the Asus Turbo Edition of the GeForce RTX 2080 Ti that comes with in-built blower-style cooling. There are also a number of premium cooling fans from Noctua visible along with a hidden Ryzen Threadripper underneath its large cooling solution. On top of that lot, the builder also mentioned he had installed 128 GB RAM using eight sticks at 16 GB each and had selected a high airflow Corsair Carbide Air 540 case for this high-performance beast.
Apparently, the computer does not suffer from thermal throttling and has been measured at 45 dB under full load, so it seems the cooling system doesn't deafen users. Unfortunately, the builder didn’t offer screenshots of the incredible OctaneBench score and there were some slight discrepancies in regard to temperature (max. 75 °C and max. 78 °C both mentioned) and sound measurements (@full load, both 45 dB and 46 dB stated). Scores for systems wielding 4x RTX 2080 Ti cards average 1,182.25 on OctaneBench – but this is for version 4.0 and the builder may have used an older version. Or like he states in his original tweet - he has built a very fast computer.
