Test Object: Monsterlabo and the Exploration of the Impossible
The Z390 board comes from ASRock, Intel's Core i5-9600K and Nvidia's GeForce RTX 2060. Oops, sometimes quickly rewind to the heel with the passive thing. And that should be passively coolable? The CPU is certainly it, but such a 160-watt graphics card? And on this topic Powercolor with Schmackes failed at that time and there it was only 130 watts. Oh, let's just let it crash, you'll have thought at Monsterlabo and you just started packing all the stuff in with vigour.
Which brings me to the test setup. I also want to spoil something: according to hardware info, Aida64 and GPU-Z, this is still wonderful even at 22 °C room temperature. Wouldn't it be me and the evil technique as a spoiler. If such an expensive fun cooling, then sometimes extra-expensive technology has to compete against it. technology that the manufacturer does not have. And so, rather unplanned, almost something like a partnership began, whereby the tester inadvertently mutates into the lifesaver of the installed hardware. Even without a rescue lane.
Test setup with new infrared equipment
As always, the infrared Trinity comes from Optris in Berlin and hears the name Pi640 and twice Xi400. The Pi640 has three interchangeable lenses, but this time I resorted to the normal lens. This allows the graphic art to be carefully illuminated. In addition, there is a camera with wide angle optics for the heatsink and one with macro lens for the voltage converter areas of the motherboard. The whole thing is wired separately and ends in a monitoring window. After all, you can already record nice videos with the 30 FPS, still images are not an issue anyway, they fall off by the way.
In the following, I have delighted all measuring points, depending on the surface, with special transparency varnish ("tropicalization"), matt-black measuring varnish or measuring tape. This also applies to heat sinks that I have attached, which I have used in the further experiments. By the way, I fixed these with thermal glue and not with tape. By the way, you can easily remove this adhesive if you use the capillary effect. Simply oisopropanol on the edges and wait for 10 minutes. Klack, and off it is again.
The still relatively market-fresh Optris Xi400 are what couch potatos are, because unlike the Pi640, they have an integrated moto control for focusing. And because I can, I also brush all relevant parts of the heatsink beautifully compliant with the rules with ugly black measuring varnish. Otherwise you only measure crap and the article would ultimately only be comedy. The camera technology is calibrated from the house and so the idle results in approx. 30 minutes of operation time the following image.
I later replaced the two motor cameras again and used them as described above. In the end, this resulted in better monitoring. Learning curve and so…
Full CPU Power
For this measurement I simply disconnected the CPU fan. The CPU part is still a slap in the back for the Monsterlabo First. The CPU runs under Prime 95 with AVX at a package temperature of 67 °C after 30 minutes. According to the sensors, the power dissipation of the CPU is 105 watts and only the motherboard has a slight fever curve in the voltage converters, which at the end at approx. 84 watts. This results from the rather small VRM heat sinks and the lack of cooling due to a helping air flow. With a fan, the fun is only 80 °C.
I see the limitation in the CPU range rather in the ability of the motherboard to work high performance on the voltage converters even without more fresh air still cleanly than on the housing and its cooling performance. So you have to pay attention to what VRM cooling performance gives when choosing the motherboard. If that's missing, there's some roast piglet Deluxe at some point or the hype train makes a smooth safety full brake.
