Stock performance on the Antarctica is certainly impressive, clocking in around the same as the Dark Rock 3 and the TD02 AIO water cooler from Silverstone, of course, we’re hardly taxing the cooler at stock clocks, but this is a solid result overall.
Putting it under pressure with 4.5Ghz clocks, the Antarctica didn’t move too far from the middle of the chart, competing with many more expensive coolers, including a few AIO water coolers and that’s certainly impressive overall. It’s on par with the similar design AR07 from SilverStone too.
Barely a whisper at stock clocks, you’re unlikely to hear this at all when it’s running.
A bit of heat pushed the fan RPM up a little, but it’s still remarkably quiet and unlikely to be of concern. Although given the temperatures we’ve seen, you could easily lower the RPM to cut some noise, or get away with pushing the fans harder for better performance, the choice is yours.
