For example, because it is conductive, if liquid metal TIM leaks onto the board, there is a risk of a short circuit in the board. Liquid metal TIM has many advantages, but it is a material that "poses a challenge to use" (Mr. Teaming up with a material manufacturer and know-how in application He believes that liquid metal TIM will be a powerful tool in cases where heat sinks are expensive and in need of help. Otori), but he prefaced it by saying, "As an engineer, the less expensive a device is, the more I want to use it" (Mr. So will liquid metal TIM be used in other electronic devices in the future? As for that, "I don't know" (Mr. In other words, the use of liquid metal TIM "makes sense in terms of cost and quietness" (Mr. The speed of the cooling fan can also be reduced, which reduces noise. In other words, even if we use liquid metal TIM, which leads to higher costs, we can reduce the total cost of cooling as a result," says Otori. On the other hand, if thermal grease is used, an expensive heat sink with high cooling performance is required. This is because if heat can be recovered efficiently near the heat source, there is no need to spend money on heat sinks and cooling fans. However, when considering the thermal design of electronic devices, the more effort is put into cooling close to the heat source, the "better the cost performance" (Mr. Liquid metal TIM is more expensive than conventional thermal conductors such as thermal grease. In other words, the smaller the die size, the lower the cost and the more difficult it is for defects to enter the die, which leads to higher yields. The reason for the small size of the SoC die is that die size is directly related to cost and yield.

On the other hand, it is rare for a PS4 SoC to operate at the very edge of TDP, and even when gaming, it generates only a few percent of its TDP. As a result, TDP (Thermal Design Power) values and the amount of heat generated during gaming are "about the same".

That's because the PS5's SoC "basically runs at almost full power during gaming" (he says). The heat density of the SoC, especially during gaming, is "much higher" (he said) than the PS4. They decided to use liquid metal TIM because the main processor (SoC) had a high operating frequency, but the die was small and the thermal density was "very high" (Mr. In addition to the design, we began to consider various aspects of the adoption of liquid metal TIM, from the manufacturing process to procurement. Preparations for the adoption of liquid metal TIM began about two years ago, when the configuration and shape of the PS5 hardware was roughly decided. This article will be divided into two parts, Part 1 and Part 2, based on the interview with Mr. The thermal design contributed greatly to the cost savings in achieving this price.

The PS5 is available in two models, one with an optical disc drive and the other without, priced at US$499 and US$399, respectively, which is a bargain against the specifications. The noise of the cooling fan during gaming varies depending on the situation, but according to Otori, "the PS5 is generally quieter than the PS4". Without this liquid metal TIM, the PS5 would have been larger, more expensive, and the cooling fan would have been louder. PS5 uses liquid metal as the heat conduction material (TIM) for transferring heat from the main processor (SoC) to the heat sink. Sony Interactive Entertainment's (SIE) PlayStation 5 (PS5) console is scheduled to launch in November 2020, and Yasuhiro Otori, who is responsible for the mechanical and thermal design of the console, has been working on the PS5 This is how he describes his thoughts on the technology that played a key role in making the He has been involved in the design of the PlayStation since the PS2, and appeared himself in the PS5 disassembly video released by SIE on October 7, 2020, to work and explain the process. It took a lot of determination and preparation. "I really wanted to use liquid metal as a heat conductor. The head of mechanical and thermal design talks about PS5 disassembly (Part 1) PS5 to use "liquid metal" for preparedness, the real aim is to cut costs
