The advantage of switching to an SSD equipped with a PCIe Gen5 interface is the very high data rates. On the other hand, you have to deal with significant heating, at least for this type of hardware… And especially if they are not properly cooled.
Be careful with the cooling of PCIe Gen5 SSDs!
In their tests, ComputerBase.de found that performance could become catastrophic if this type of storage was not properly cooled. Indeed, without a heatsink, the performance of the T700 from Crucial dropped so much that the throughputs were at the level of a mechanical hard disk. The latter were then at the level of 100 Mb/s.
The other observation they made was that the maximum temperature of the Phison E26 controller was around 86°C. It is at least from the latter that serious problems start to occur. On the Crucial, the flow rates are down to preserve the controller. On the MP700 2Tb from Corsair, the system crashes, or even crashes which can lead to a risk of data loss. Well, really average behavior.
Anyway, it’s not for nothing that manufacturers recommend to use their heatsink… Or the motherboard’s heatsink. In these conditions, the temperatures are not pretty, but the T700 of Corsair holds the tests by approaching the 80°C with a throttle all the same on CrystalDiskMark.
