Aorus RTX 4080 Super Master 16G: A problem for the RX 7900 XTX

Methodology: temperature tests

The biggest hardware changes compared to non-Super cards concern the GeForce RTX 4070 Ti Super. What’s different is the GPU, the amount of GDDR6X memory or the width of the memory bus. We have the RTX 4070 Ti Super in one of the cheapest non-reference designs, the Ventus 3X, for analysis and it will be about “reputation repair” as well. MSI has somewhat tarnished it in this line of graphics cards in the past, but now it’s a technologically very attractive solution.

Methodology: temperature tests

We’re also bringing you temperature tests. You are at HWCooling after all. However, in order to make it sensible at all to monitor temperatures on critical components not only of the graphics card, but anything in the computer, it is important to simulate a real computer case environment with healthy air circulation. The overall behavior of the graphics card as such then follows from this. In many cases, an open bench-table is inappropriate and results can be distorted. Therefore, during all, not only heat tests, but also measurement of consumption or course of graphics core frequencies, we use a wind tunnel with equilibrium flow.

Two Noctua NF-S12A fans are at the inlet and the same number is on the exhaust. When testing various system cooling configurations, this proved to be the most effective solution. The fans are always set to 5 V and the speed corresponds to approx. 550 rpm. The stability of the inlet air is properly controlled during the tests, the temperature being between 21 and 21.3 °C at a humidity of ±40 %.

We read the temperature from the internal sensors via GPU-Z. This small, single-purpose application also allows you to record samples from sensors in a table. From the table, it is then easy to create line graphs with waveforms or the average value into bar graphs. We will not use the thermal camera very much here, as most graphics cards have a backplate, which makes it impossible to measure the PCB heating. The key for the heating graphs will be the temperature reading by internal sensors, according to which, after all, the GPU frequency control also takes place. It will always be the heating of the graphics core, and if the sensors are also on VRAM and VRM, we will extract these values into the article as well.

Full of latest hardware and… surprises – SOŠE Liptovský Hrádok

The last stop of this year’s HWCooling Techtour. It was different, but still energetic, professional and enriching for students. In Liptovský Hrádok, we found out the “overall winner” of the skills competition and managed to do other things that we hadn’t quite done before. Third time’s the charm? Definitely. The students were (again) very active, curious and overall well prepared. Read more “Full of latest hardware and… surprises – SOŠE Liptovský Hrádok” »

Premiere of Intel Core Ultra 200S at SPŠT Martin

The old cinema hall of the Secondary Industrial Technical School in Martin has come to life again. On the occasion of the world premiere of Intel Core Ultra/Arrow Lake processors and Gigabyte Z890 motherboards, we organized expert lectures for the students and they could also physically see the hardware on site. In addition, they demonstrated their knowledge and also their excellent skills in mounting coolers on a CPU. Read more “Premiere of Intel Core Ultra 200S at SPŠT Martin” »

Intel Arrow Lake pre-premiere at SOŠE Žilina and we’re going further

In the spirit of “Hungry for Knowledge”, to celebrate the release of the new Intel Core Ultra 200S (Arrow Lake) processors and Z890 motherboards (Gigabyte Z890), we’re making the rounds to a few high schools to show the public the latest hardware. In Žilina, it was yet unreleased desktop processors and motherboards, so in this case we are writing about a pre-premiere. And a worldwide one at that.
