Temperatures and Boost Clock
The card boosts to just under 2700 MHz when cool enough. This is also not a fair-weather boost, which in my very extremely demanding test game (this time Wolfenstein: Youngblood) still offers a proud 2648 MHz and more as the temperature rises. Amazing. The memory can also be overclocked to 1900 MHz. The GPU could be overclocked stably up to 2.75 GHz with this cooler including MorePowerTool, not bad either. In the end, however, the self-modified cooler with the two meager heat pipes is severely challenged here. Edge temps are really acceptable at 55 to 57 degrees even after an hour, chapeau and ashes on my head for this conversion!
Now let’s move on to the recording with the high-resolution infrared camera. The PI640i from Optris has a true 640 x 480 pixel bolometer and records at up to 30 FPS. Here I use the normal lens and calibrated film with a known transmittance, so that I can de facto see inside the closed housing. I’ll leave the backplate off so I can take better measurements. Everything is rather unspectacular in idle:
Now, if you give Wolfenstein: Youngblood free rein and some air, everything heats up nicely. The bottom of the VRM is as hot as 86 °C, with two things taking revenge here: On Semi’s rather inefficient DRMOS and the meager VRM heatsink. The memory shows a maximum of 77 °C on the PCB side, but this is due to the significantly hotter PCB at this point, although the modules are cooled well from above. The hottest spot is the area of the current carrying tracks between the PWM nodes and the BGA, with the GPU seeming almost cold in comparison. Cost down on the board and therefore higher temperatures, but still not harmful.
If we switch to the torture test, I’m starting to get a little concerned. Because the almost 98 °C in the hotspot have nothing to do with the cooler itself, which works perfectly. Here simply the board losses strike and I can only advise to pack a heat conduction pad between board and backplate at this point!
Fan speed and volume
Now let’s look at the consequences of graphics card warming. Of course, I’m also interested in the noise level of what is now being emitted as complex fan noise. Whether closed or not, the temperature curves look very similar. The card in the closed configuration still acts very, very confidently, with the revs only just above 1250 rpm. Amazing, but true, so you can hardly hear them despite prolonged full load.
Now let’s move on to the noise level and the sound character. With about 34.7 dB and a power consumption of plenty of 140 watts, I measure a very low value, which can still be noticed, but which is absolutely not disturbing. The sound characteristic mixes a barely audible hiss with a slight bearing noise, but this disappears completely towards the top. The stock noise creates a kind of slight peak in the low end and lower mids. Nevertheless, you can live with it well, because it remains reasonably quiet overall. Of course, this is not the original radiator, so I only have the reading but no detailed analysis. I’ll have to post those when fans are available.
