Performance is all good, but what about operating condition? Well, without a heatsink, I simply cannot recommend the SX8000, or any M.2 SSD for the local environment. Our tests were done when the ambient temperature was 39C. And that’s not even the highest we have gone so far in the summer heat that’s yet to come. As mentioned in the unboxing section, XPG sent us their SX8000 M.2 SSD without a heatsink since they sent us their Storm M.2 RGB heatsink as well to use it with. The SX8000 is actually sold with a heatsink in the market, this is a special case in our situation. The results with and without the heatsink can be seen bellow and also, the following result can be taken as a general example for M.2 drives without the heatsink, which just isn’t really a good idea.

Once the system booted freshly, the SX8000 had a minimum temperature reading of 45C without the heatsink, however with Storm, we saw a drop of 10-degree Celsius in the minimum temperature. In a couple of minutes, the SX8000 was sitting at an average temperature of 59C on idle load without the heatsink. But with the Storm heatsink, we saw about 9-degree Celsius drop in the average temperature without load. The max it reached without the heatsink at no load was 62C. Whereas with the heatsink, there’s about 10C difference once again. And when we put some load onto the SSD with ATTO SSD Benchmark, the SSD reached a max temperature of 69C Without the heatsink. After the SSD reaches 70C, it will start to throttle the performance to prevent the SSD from getting burned or damaged. So even in such harsh condition, the SX8000 itself was able to perform at full speed without crossing that throttling barrier. And the XPG Storm dropped a few more degrees Celsius from the chart to make sure you don’t cross that barrier.

These are the results that we got from our test rig. Bear in mind that our test rig included a chassis with limited positive air suction, and the ambient temperature wasn’t really ideal for this testing. The readings may differ from system to system and, of course, from environment to environment. We wish that we could have tested the SX8000 with the heatsink that it’s sold with on the market right now as it would be interesting to see how much difference throwing a 20mm fan in the mix have. But we are glad that we had the XPG Storm to keep the temperatures under control.
