Aspire 7 A715-42G-R20C SSD overheating
I was trying to connect an old internal HDD through USB and wipe free space using <cipher /w:D> when the command actually started wiping the free space on the internal SSD (C:) instead. This new Acer Aspire 7 A715-42G-R20C has a 512 GB M.2 SSD from SK Hynix that overheated to a scalding 68 degrees Celsius under full write load, and just stayed at that temperature even with both fans set to 80%. The AMD Ryzen 7 5700U processor is highly efficient and never exceeds 65 degrees under full load, but the SSD explodes to scalding temperatures in just a few seconds. It only operates at less than 400 MB/s because of the overheating, which is not much higher than HDDs, and cannot operate at the advertised speed in open air without overheating. The write speed dropped down to 35 MB/s, which is far slower than an old 5400 RPM HDD at 103 MB/s. It is a myth that SSDs are more reliable than a high quality HDD, are cooler, or "quieter" when the fans need to spin faster than an HDD platter. If this model had an HDD slot, I would pull out the SSD and install a nice set of pristine platters spinning at 7200 RPM.
