Video comparison of noise levels
We don’t want to miss out on our videos this time either and compare the fan speeds of the different load conditions, which are already documented in the diagrams, with the corresponding noise levels. The 20% speed at idle at a constant room temperature of 22°C is good for a very good 30.9 dB(A), but this is a very theoretical value because it is only achieved without “Lethal Boost” and in a well air-conditioned room.
Idle: 30% speed at 32.8 dB(A)
This value is more realistic and still acceptable, since it is achieved even in “Lethal Boost” mode. Only when the clock gets stuck at 1201 MHz because the downclocking doesn’t work anymore, you end up with almost 40% speed and about 40.6 db(A) after half an hour.
Average load: 50% speed from 46.8 dB(A)
A whopping 50% fan speed is due when using simple 3D applications (e.g. Google Earth) in “Lethal Boost” mode. It’s not much less with 44-46% in nominal mode. In Metro 2033, more than 50% is constantly used after a while, even in normal mode. This is already enough for a very memorable acoustic background of the stormier kind with 46.8 to 49.2 dB(A).
Load while gaming in “Lethal Boost” mode: 65-67% RPM from 54.2 dB(A)
Now it gets really nasty for the first time. With 65% and 67% (1201 MHz fixed) revolutions respectively, the card, as already mentioned, mercilessly strikes to cool something that wouldn’t have been needed so extremely. We are already on the level of the reference cards in terms of volume.
Full load in normal mode: 73% speed with 57.4 dB(A)
Anyone who thinks that all this cannot be increased is mistaken. With simple bitmining, you already catapult the speed to 73%. A proud 57.5 dB(A) now provides a Bundeswehr runway feeling.
Full load in “Lethal Boost” mode: 80% speed with 60.5 dB(A)
Now comes the jumbo. It’s practically unbearable how the fans struggle, even though the temperatures are so low that you really wonder whether they’re supposed to produce popsicles. A card that stays significantly cooler in OC mode than in the factory state should be awarded with the Golden Question Mark on the ribbon of honor.
Interim Conclusion:
It doesn’t really need to be commented on, the fan profile for the “Lethal Boost” mode is terrifically misshapen. Sapphire should definitely improve this, especially since the clock yoyo caused by the thermal peaks is more suitable for a PowerTune memory run than for serious use.
