Test run and temperatures
As always, I connect the graphics card directly to the Chiller to offer absolutely the same test conditions at 20 °C water temperature. After a density test with 600 l/min, I start the test run with a more moderate water flow rate of 80 l/min and with +50% power limit including maximum clock speed. I then take the hardness test with manual OC, just under 2.2 GHz and just over 300 watts of GPU power, which as a tBP total crumbles the 350 watt mark with a gesture of nonchalance and is realized with 120 l/min flow. So here we are knocking and not cracking!
As already written: the water temperature was as always constant 20 °C and the room temperature was 22 °C. This means that we now have the best conditions for later comparisons with other products, which I also had in advance in the test. But how well is this cooling adapted to the Sapphire RX 5700 XT Nitro+ in reality and with the extreme OC? The 2 GHz mark is not a hurdle. According to diode, the GPU is 40 °C warm, the board under the BGA then 4 degrees more.
For the 2.2 Ghz I need a little more bums and the power consumption of the GPU alone is already just over 300 watts, i.e. 110 watts above what is due with the original model. Since the flow has been increased for safety reasons so that the GPU does not become too warm, it then reaches just under 44 °C at 50 °C on the board below. As a positive consequence, the voltage converters and also the RAM are really cool, because the well over 350 watts TDP as a total power consumption are no longer a small matter.
It turns out that in each of the two cases, the cooler obviously benefits from the new pads, especially when it comes to memory, and that Sapphire has produced a really well-designed board that can make overclocking quite a lot of fun. However, since this cooler differs significantly from that of the reference design, it is difficult to compare the values. But the performance is right.
Summary and conclusion
Conveniently designed cooling block meets well-designed graphics card. For this there is my special Approved-Award, because the 2.2 GHz are not from bad parents at such temperatures. And it is also a prototype that also makes it into the series, because it should also be available for order. You have to wait a little longer, but I have a little more for my museum. Because I will have to dismantle the Nitro+ for further tests. It's a pity, but I only have one 🙂
