As expected the PCS+ R9 290 remains silent when it’s idling. While gaming, the noise level depends on the load, but for the most part the card stays on the quiet side. In very demanding scenes, at high resolutions like 2560x1600, the card gets a bit louder. However, even then it is quiet enough for just about any living room.
Even after a few rounds of GPU intensive benchmarks, the temperature never topped 64 degrees. Since our test bed Cosmos II chassis is spacious and well ventilated, we decided to switch off the case fans and reduce the airflow. That put a lot of strain on the PCS+ cooler, but it still performed admirably. The GPU heated up to 68 degrees and the fans spun up to 71%, or about 3000 RPM. They were audible, but not really loud. Needless to say this is a highly unlikely scenario, as every enthusiast knows that the chassis must be properly ventilated.
