Last month, news broke that Sony was revising (albeit rather low-key) its original PS5 digital model to reduce its weight by about 300 grams. The new model has been sold in Australia and Japan and its ID is “CFI-1100B”. In terms of changes, there is a lighter plastic-head finger-friendly screw on the base that can be turned and loosened with your fingers instead of requiring tools such as a screwdriver.
But this does not explain the huge difference in weight. Well-known video blogger Austin Evans quickly disassembled the new model and found that the new model also uses a degraded heat sink, which is larger than the original The number of models has been drastically reduced. Most of the weight difference between the two versions seems to come from this change.
As one might expect, this led to a difference in temperature. The newer model runs at a significantly higher temperature, reaching 55°C, while the original version’s temperature is around 52°C. The measurement is performed in an environment of 24°C.
However, the fan noise of the new CFI-1100B model is lower than that of the old model, which means that people who are very sensitive to noise may prefer the new version. Compared to the original version, the fan is clearly better designed, which may help reduce the sound output, even though the device runs hotter.
Although the CFI-1100B is an improved version of the PS5 digital version, there may also be a revised CD-ROM version in progress, or it already exists as a different PS5 model, with the ID “CFI-1115A”, which was received by Twitter users as early as May. @geronimo_73 found.
