So, after all the product data, the two parts have to show what they can really do. Money wasted or good added value after all? First of all, let’s look at the curve diagrams of the probe. Interestingly, the final values are almost exactly the same as those that can be read out with HWInfo64, for example. However, the measurement intervals there are much too coarse to get a good timeline.
By the way, we can recognize the passively cooled runs by the dashed curves. Of course, the curve of the original looks the most horrible here, but I had already written that. The temperatures rise up to 71 °C (even up to 72 °C for a short time), then the SSD throttles and it returns to an almost constant 70 °C. The other curves are actually self-explanatory and the increase of the other cooling variants is not quite as steep.
Now let’s take a look at the bar chart. At a room temperature of about 20-21 °C, the active variants are only 4 to 5 degrees above this ambient temperature, because the SSD still consumes some performance even in normal idle. Even without a fan, the somewhat weaker G-M2HS03-F is still just under 30 °C, while the original heatsink is in the table with 34 °C. If you now look at the temperatures at full load, it becomes clear why I didn’t even disassemble the cooler, but left it on right away.
The maximum values and the average values are always on par with the two coolers from Graugear. A feat, because nothing throttles. With 33 °C at full load and 5600 rpm, the G-M2HP04-F is even cooler than the original at idle! The G-M2HS03-F can also convince, but is about 5 degrees warmer. In passive mode, the difference is only 4 degrees, whereby both coolers stay below 50 °C and can thus be operated without a fan without any problems. But we wanted it to be especially (nicely) cool.
Summary and conclusion
The German supplier CHAB GmbH with its Graugear label and the Asian ODM have actually done everything right, and the build quality and performance are also really good for a new product. The price could certainly have been lowered if they had paid more attention to the tooling and not designed two similar products independently of each other. The U-frame could have been identical, the fan of the G-M2HS03-F should not have been hidden and the accessories are also a bit too lush.
But what the heck, in the end the 2-3 Euros don’t kill you either, because the competitors are even more expensive in some places. No, they are all not cheap, but if you want to be beautiful (cool), you just have to suffer. The performance is more than sufficient and I do not send the parts back. It wasn’t that expensive, after all. But unfortunately not cheap either. Only with the flat heatsinks, in contrast to the SSD, I could not really warm up. They really only fit on an older PCIe 3.0 SSD.
