We took more than two years to prepare well to solve these problems.” In order to handle such materials, it is necessary to take measures for manufacturing equipment as well. Above all, it is highly corrosive to aluminum used for parts such as heat sinks. “ However, since liquid metal is conductive, if it leaks to the substrate side, it will be short-circuited. “I’ve always wanted to use liquid metal,” he said. Liquid metal TIMs usually go hand-in-hand with certain issues, and according to Otori, Sony spent two years coming up with solutions to these problems.
Otori spoke more about the aforementioned difficulties in the manufacturing process as well. “Even after overcoming the difficulty of handling and adopting it in the manufacturing process, PS5 was finally able to adopt liquid metal, which is expected to have a great effect.” If you change to a TIM of 100 yen here, you can get the same cooling effect even if you use a heat sink of 500 yen. In other words, the total cost can be reduced. “ The standard for thermal design is to spend money near the heat source. As an analogy to general thermal design, let’s say you have a system cooling structure that costs 10 yen for a TIM and 1000 yen for a heat sink. “The main reason is cost,” Otori said when asked about why Sony decided to use a liquid metal TIM in the PS5. Even though a liquid metal thermal interface material (TIM) in isolation is costlier, it is effective enough that it allows Sony to go with cheaper components elsewhere. The PS5’s liquid metal cooling, for instance, was chosen for the console to reduce the overall cost of the cooling system. Similarly, they made cost-based decisions in other areas of the cooling system as well, as Yasuhiro Otori, the head of PS5’s mechanical and thermal design team, explained in a recent interview with 4Gamer. Sony have recently talked about how wanting to cut down the costs was one of the reasons for using a single large fan in the PS5 instead of two ( which is what resulted in the console’s large size). Under no circumstances can liquid metal thermal paste be used with heat spreaders or cooler bases made of aluminum.Earlier this year, reports began circulating that the PS5 would have an “unusually expensive” cooling system, and recent details that Sony have revealed about the console’s hardware have certainly fallen in line with that (and early impressions have suggested that the investment will pay off). It goes without saying that delidding a CPU voids the warranty and should only be attempted with proper tools and by advanced and experienced users only. This process is called delidding and since liquid metal TIM is more conductive than the default IHS, it yields even better results than applying the paste on the heat spreader. Overclockers often even remove the integrated heat spreader (IHS) of the CPU and apply the TIM directly to the die.
It works the same way silicone-based pastes do, but thanks to the higher conductivity, liquid metal users can squeeze the last bit of performance out of their cooler and, by extension, their CPU. Abstract: We present a single-phase liquid cooling technology that exploits the highly conducting nature and superior thermophysical properties of liquid metals to cool high density power sources (>200 Wcm/sup -2/) with very high heat transfer coefficients (/spl sim/20 Wcm/sup -2/K/sup -1/), and pump.

Liquid metal thermal compound has much higher thermal conductivity.Īs an example, the be quiet! DC2 Pro liquid metal TIM has a conductivity of 80 W/mK (watts per meter-Kelvin), while the silicone-based DC2 only features 7.5 W/mK. High-performance liquid metal cooling loops. It is easy to apply, easy to remove, safe to use, and for most users this will be the preferred method of use.
Silicone-based thermal paste, like the be quiet! DC2, can be used with any CPU cooler and processor. This is to improve heat conductivity and garner maximum performance.

The most common and often pre-applied thermal compounds consist of silicone oil and zinc-oxide as base components. Since air is an insulator, it is the highly heat-conductive thermal paste’s job to compensate for the imperfections and assure even heat dissipation over the largest possible surface area. These blemishes are unavoidable due to production processes, and they trap air when 2 surfaces are pressed onto each other with no filler material.

While the surface of a CPU heat spreader looks smooth from afar, under a microscope it can easily be mistaken for the surface of the moon, full of craters and imperfections.
