GamersNexus has tested MSI’s M.2 Shield thermal impact on M.2 SSDs and find out that M.2 Shield has actually had a negative effect on an M.2 SSD’s thermal performance raise SSD temperatures instead of lowering them like advertised.
As you can see from ‘GamerNexus’ video on MSI’s “Heat Shield”, were they showcases several design flaws on the product, which uses an exceptionally thin metallic shield as a heatsink which does little to help cool the SSD and has the unwanted side effect of trapping heat inside of SSD, increasing the temperature of the underside of M.2 SSDs.
In GamerNexus’ testing, it was found that the top side of the SSD had thermals lower by 1-2 degrees Celsius at idle and under load, with the bottom of the SSD having thermals increase by around 4 degrees at both in idle scenarios and under load.
This raises a major issue with modern M.2 SSDs, which have components on both sides of the PCB, causing heat to be produced at both the top and bottom of the SSD. This makes these SSDs difficult to cool efficiently, especially when under heavy loads.
While some M.2 SSDs have been found the issue of suffering thermal throttling under load, though it also is said that this only happens under benchmarking loads, as no day-to-day applications can produce enough data to cause such thermal loads. GamerNexus’ tests were conducted over a 60-minute period under IOMeter, which is an SSD load that is higher than any consumer system could produce outside of benchmarks.
While MSI’s M.2 Shield has been found to increase thermal loads under benchmarking loads, but the question is if this will actually affect consumers, as will anyone actually have their SSDs under full write loads for 60-minutes in the real world any given time?
