To find the supported temperature on an Intel® Optane™ SSD or module, follow these steps:
Generally, it is not necessary to have a cooling solution system for the Intel® Optane™ SSD or module. If a system comes with a cooling solution system for the SSD or has the option to install one, it can be integrated.
Without a thermal solution, it's possible to experience a performance impact if the device reaches a temperature of 80° C (throttle set point). At this temperature, the device will limit its performance to prevent overheating.
The SSD won't be damaged as the throttle set point has been reached. However, the built-in thermal throttle safety feature that prevents damage can result in significantly lower performance or shutdown.
If your motherboard came with a thermal solution, you can use it. Under heavy sustained storage workloads these thermal solutions may extend the time for the SSD to reach its thermal throttle set point. Although Intel hasn't validated these thermal solutions to deliver the same level of sustained performance as the solution provided by Intel, any thermal solution will provide some benefit. Results may vary based on the efficacy of the solution.
