Graphite sheet application on SSD flash memory

SSD flash memory will wear out over time when exposed to high temperatures. This loss leads to electron leakage and misidentification errors. When an SSD overheats, the controller may fail, resulting in various erratic disk behaviors. For example, your SSD is not recognized by Windows. Your computer cannot find your SSD, Your SSD appears as unformatted. When you try to copy files from the SSD, your computer always crashes and other errors, so it is necessary to add heat dissipation materials to assist cooling, the following simulation flash memory hot spot area, test artificial graphite, silicone gasket + metal shell material on the hot spot temperature for difference comparison under the same conditions.

1. Test method：

a. Test in a constant temperature and humidity box, temperature 23~25℃, temperature: 30~70%

b. Simulation platform heating temperature, power 3W;

c. The highest temperature of hot spot on the back of heat source was obtained by infrared thermal imager.

d. Test time：3min;

2. The infrared imager takes the maximum temperature point.

3. Temperature rise ∆T/℃ data chart comparison:

4. Conclusion:

Too high storage temperature of desktop computer or notebook SSD will affect the performance, even lead to hard disk damage, so it is not worth the loss. You can try to install a heat dissipation solution for the SSD to reduce the heat on the motherboard when the large capacity SSD is running. Conventional cooling structure metal shell + silicone thermal pad is compared with the artificial graphite, the thickness of the graphite is only 0.5mm, the same as that of the silicone thermal pad, without the external metal shell, the temperature difference of the test under the same condition is ∆T/6.3℃, and the temperature difference of the test is ∆T/23℃ compared with direct heating, the temperature difference is small and the cooling effect is limited. For artificial graphite, the temperature difference of the test is ∆T/32℃ compared with direct heating , the temperature difference is large and the cooling effect is obvious, so the artificial graphite can reduce the hot spot density well and make the SSD run more stable.
