Review: be quiet! Straight Power 11 Platinum (1,000W)

Temperature and Noise

be quiet! does a good job at keeping the supply, if you excuse the pun, very quiet at all loads. You cannot readily hear the fan at 500W of load, and we know this because we connected it to a system powering a 64C128T Ryzen Threadripper 3990X running at full CPU load.

It also produces decent temperatures at low loads, though the 52°C reading at full pelt feels a bit high.
