This build was done in one of the first prototypes of the HEX GEAR R80 by our CTO, Hans Peder “p0Pe” Sahl, to test the R80 to its limits in both space and cooling capacity. With the help from some of the biggest companies in the business, we put together one of the most powerful gaming PCs possible and stress tested it to the limits!
We will be posting a separate article about the temperature results when we finish benchmarking this beast!

Temperature test results
Since this entire build was done to show how much you can cool with the R80 case, let’s get some results on the table! Worth noting is that the fans goes all the way up to 2200 RPM, but since we do not think anyone would be satisfied with having their system running at that noise level, we have decided to test what the minimum fan speed for acceptable temperatures would be.
First of all, we overclocked the CPU and GPUs to their limits to get most the performance possible out of the system. Then we ran a 3D mark firestrike test, which you can see by following the link below:
The system did not get anywhere near hot on this test as the benchmark is somewhat short. So to get some better real world results, we decided to push the system with a few classic stress testing tools.
The first test we did was with our render program Keyshot, which utilizes the CPU to the maximum, to render animations and 3D models. During this test, the system used a whopping 600W. We suspect that the reason this number is so high is because of the overclocked CPU that was fed a generous 1.3 Vcore.
CPU stress test – Keyshot
The picture above is our thermal setup where you are able to see all the temperatures in the testing setup. In each box is a description of what the graph shows, and in the right of each box is a number of values showing respectively:
- The highest value measured
- The lowest value measured
- The average value over the time measured
- The time shown on the graph (not to be confused with total up time – This timer only shows how far back the graph logs)
Looking at the picture above you see that keyshot ran for just about 30 minutes with the CPU reaching a maximum temperature of 72 C° on the cores, and 75 C° on the package. No doubt that this temperature can be improved by lowering the Vcore, or lowering the overclock. It is worth noting that smaller chips like the 6700K would not get anyway near this hot at the same overclock.
Looking at fluid temperature and fan speed, we see that the fluid reaches a max of around 35 C°, which gives it a delta c on 11c from the ambient room temperature with the fans spinning at a max of 1200 RPM.
Graphic card stress test – Furmark
If we go on to the more extreme benchmark called Furmark, which will stress all grafic cards to the max, we can really see where the 1500W power supply comes in handy. At this test, the system is pulling a whopping 1400W from the socket! We did also try running both Keyshot and Furmark at the same time, but this actually led to a lower total power consumption as well as lower overall temperatures, so this was without a doubt the most stressful test for the system. The graphic cards have been overclocked to the maximum stable clock which was +200 MHz on the core, and +500MHz on the RAM.
Looking at the temperatures, you see that the GPU temperatures reaches a maximum of 61 C°. The fluid temps climb up to just above 50 C°. All this with the fans spinning at a max of 1400 RPM. Turning the fans up a few hundred RPM did lower the fluid temp to just above 40 C°, but again, we where testing with lowest fan speed needed.
Overall real world test – Crysis 3
Last test is what we would consider a “real world scenario” with the CPU overclocked to 4 GHz and the GPU’s with the same overclock as before. We turned the heat up in our testing area a bit, now reaching an ambient temperature of 26 C°, and then sat down playing Crysis 3 for three hours straight.
We aimed for a slightly lower fluid temperature so the fans was put to a max of 1500 RPM, giving us very fine temperatures on both the graphic cards and the CPU during the entire gaming session.
The 60 mm thick 480+360 radiator we have in this build has proven to be more than capable of cooling this entire overclocked system. Thinking about how this system draws almost 1400W from the socket under load goes to show that if you are planning on a SLI system, you will never run into any problems cooling wise and can have your fans running at a very low setting. This, along with the fact that newer graphic cards will use significantly less power, makes the R80 a perfect combination of space and features and fits perfectly into our idea of not making the case bigger than it needs to be. If you still think that you need more cooling, there is the option of upgrading to two 420 mm radiators, which would increase the total radiator surface from 100800 cm^2 to 117600 cm^2.
