To simulate a challenging gaming load I chose our lone “hot” day thus far in Michigan, and used the ASUS Strix GTX 1080 Ti in a very warm room (AC off, ambient over 80 degrees F) with an endless loop of Unigine Heaven. In this “worst-case” scenario I saw GPU temps max out at 84.7 C, with the fans spinning at 70%. The Ryzen 5 3600X CPU hit a max of 61.3 C during this test session, using the stock cooler. Noise hit 46.2 dBA with the SPL meter positioned 12 inches from the top of the case, above the running system in my build’s orientation. A more modest build (or an air-conditioned room) produced deltas that were much lower, with my living room RTX 2060 build producing a max 71 C GPU temp with ambient air of ~72 F / 22 C.
My son decided to use my infrared thermometer as a hammer, so it was unavailable for this review. The aluminum was quite hot to the touch after a long benchmarking session with a hot-running GPU, so keep that in mind when deciding on enclosure placement. Blower-style cards are a different story – but that’s always the case. If the GPU produces a lot of heat and doesn’t exhaust it from the rear bracket, any case is going to suffer without high airflow. This was a perfect test scenario for a top-mounted exhaust fan, but I did not end up getting to that. It should help – but in any event make sure you keep plenty of room above this case for heat to escape the panel above your system.
Ultimately take these results with a grain of salt, but essentially the SUGO 15 is open enough that it allows components to breath properly, and by the same token won’t mask noisy coolers if you have them.
