Each different GPU manufacturer has its own methods of attempting to reduce and eliminate noise from fans while also managing to keep the heatsinks cool enough to keep the GPU itself from slowly melting. These efforts always have varying results, so how did SAPPHIRE do with the R9 390(X) Nitro Series? Our measurements are taken 20cm away from the case. All Fans were disabled while testing. Our testing device however, has to be replaced as it has only a low sensitivity rate starting from quite some decibels. While cooler designs get more silent by the year, we'll need to be able to go in more and more detail...
Idle noise is astounding as always with those new coolers. Our testing device isn't sensitive enough to measure the differences between the coolers from Club3D, MSI and SAPPHIRE when in idle state. In load however, we can see some changes. the SAPPHIRE Nitro editions aren't as silent as those Twin Frozr fans from MSI, but certainly do a great job as it's more silent
than the triple-fan design of Club3D on the RoyalAce. When we're using the card on full load, the noise is barely noticable as the rig is located under our desk. Turning the fan's speed over 50% gets quite noisy to our opinion, but still reasonably silent. However, the noise accumulates quickly after this value. We've never seen the fan's speed pop over 40-45% implying that the temperatures aren't too high.
The intelligent fan control of SAPPHIRE's nitro series ensures you get the lowest possible noise for every appropriate use. Depending on the load rate of the graphics card, the fans will be enabled and spinned faster.
Let's have a look upon the heat dissipation effeciency of Tri-X thermal design.
Room temperature is 24°c
The Tri-X design can take a hit and keeps the factory overclocked cards very cool (and quiet). While Club3D's RoyalAce takes the lead, we can see that the Tri-X cooler from SAPPHIRE delivers a better cooling job than MSI's Twin Frozr design. The reason why the GTX980 has a lower tempurature is partly related to the fact that it consumes a fair amount less. However, while MSI can easily adjust the fan speed to deliver better cooling, SAPPHIRE's solution will be a little noisier when increasing the fan speed. In the end, the thermal design really stands out as one of the better we've seen so far.
