And what about the direct and indirect consequences of heating due to the electrical power absorbed? Of course, I will later be interested in the noise level of what is now emitted as complex fan noise. No matter if gaming or torture, the temperature curves look very different between the cards!
MSI RX 6950 XT Gaming X Trio
Let’s start with the big card. The cooler does its best to dispose of the more than 400 watts of waste heat properly, but it gets quite tight. At 1800 rpm (later 1500 rpm), the three propellers already rev up quite a bit and in very poorly ventilated cases, it even gets really loud from 2500 rpm. MSI would have been better off using the cooler block of the RTX 3090 Ti SUPRIM X, which easily irons out 500 watts. I don’t want to write uncharitably, but what was still possible with the RX 6900 XT is already too tight here for my taste.
The punishment follows on its heels, because the 43.3 dBA at around 410 watts are quite audible, unfortunately. And it’s not just the propeller tearing noise (see range around 1.8 KHz), but in the lower frequency range also the drive between 100 and approx. 240 Hz.
MSI RX 6750 XT Gaming X Trio
The medium-sized card also benefits from the adopted cooler of the larger RX 6800 Gaming X Trio with now three instead of two fans, which are then also allowed to turn a bit lower. The 1200 rpm are actually always undercut if the case is well ventilated and there is no heat buildup.
The card is still relatively quiet with 34.3 dBA, but you can already feel that the fans have to push more waste heat through and away.
MSI RX 6650 XT Gaming X
The MSI RX 6650 XT is the coolest and quietest of the three cards tested. At just over 1100 rpm, the two fans are barely audible. The initial loop at about 1300 rpm again follows AMD’s peculiar “fuzzy” logic and is the trademark in the RDNA cards.
You won’t do anything wrong with the measured 32.3 dbA and you won’t get a hearing loss. Here, the larger cooler shows that it is not a bad investment to oversize something for a change. Fits like this.
