AMD Radeon RX 480 8GB Review – Polaris Is Here
Radeon RX 480 – Temperature and Noise
The reference blower type cooler on this RX 480 isn’t the best cooling solution out there. Expect that partners with their non-reference cooler will do a better job at keeping the RX 480 cool. But it doesn’t mean that the reference cooler can’t do its job either. I’m getting an average of 49° degrees Celsius during idle to light load operation. The fans do not stop spinning but they are silent at these temperatures.
I opened and simultaneously run both Heaven and Valley benchmarks, and at full load the temperature quickly went up to 82° degrees Celsius. I could feel the heat exhausted at the back already. The fans also start to increase its RPM, but the default fan profile will only let the fan run up to 2200 RPM. Beyond that speed and the fan become noticeably loud, and anything above 3500 RPM fan speed is already noisy and very loud.
Overclocking the Radeon RX 480
Overclocking the AMD Radeon RX 480 was easy thanks to the new Wattman application. However, I wasn’t able to get any much higher from the stock speeds. There were lots of options to tweak the card, but I could only push the card up to 1350MHz. Beyond that, I would see artifacts, flickering or would result in a video display failure. I also can’t push the card any further due to its reference cooler. I hope that AMD’s partners could hit better out of the box overclock speeds with their non-reference design and cooler.
The improvement or difference in overclocking the RX 480 can be seen on my 3DMark Sky Diver and Fire Strike benchmarks on the next page.
Now, let’s proceed to the most important part of this review, the benchmark results of the Radeon RX 480.
