We took note of the drive’s temperature during some of our benchmarking runs. Corsair's MP600 GS doesn't come with any form of heatsink which is always a bit of a worry because of the heat that Gen 4 drives generally put out. That worry is alleviated in the MP600 GS somewhat by the fact it uses a four-channel controller. The hottest the drive got during benchmarking was when it was running the default Peak Performance profile in CrystalDiskMark 8; 51°C for both reads and writes, which is about as close to the 70°C maximum you would want to get. When running the 4K tests the drive averaged 38°C comfortably inside that official limit.
