Phison has a fix for its overheating PCIe 5.0 SSD controller
Phison has acknowledged serious overheating issues with its new PCIe 5.0 controller, the E26, which can cause drive shutdowns and file system errors. Phison, arguably the leading producer of SSD controller chips, says it has has a new firmware fix in the works.
Speaking to Tom's Hardware(opens in new tab), Phison says the new firmware is currently going through a full validation process before it can be released. However, the company also emphasised that SSDs using the new controller need to be run with some kind of heatsink, even with the new firmware.
«It is important to note that all E26 SSDs shipped without a heatsink are intended to be used with a heatsink,» Phison says. That inlcudes drives like the Crucial T700, which we've taken for a spin(opens in new tab), and the Corsair MP700 which we'll have a full review of shortly.
The Corsair drive in particular is interesting because it ships without a heatsink. Both Corsair and Phison say that most PCIe 5.0 enabled motherboards ship with some kind of cooling for M.2 drives.
In theory, then, most buyers of bare M.2 drives with the Phison E26 controller, like the Corsair Corsair MP700, should be OK. But an SSD that absolutely needs a heatsink to run is something new that will take a little getting used to.
You could argue that CPUs need heatsinks and can be bought without them. But that's long been the case. Up to now, SSDs have always been in a category of devices that could be run out of the box without additional cooling. If you bought a graphics card and it turned up without a cooler that wouldn't be, well, cool, would it?
Apart from anything else, one immediate question is whether drive performance will vary depending on the quality of the M.2 cooling provided by
