Review on 💻 SYY Thermal Paste - 2 Grams CPU Paste Heatsink for Processors and Coolers, Carbon Based High Performance, 15.7W/m.k, Thermal Interface Material, CPU Thermal Paste by Nuntawat Bridges

I noticed that this thermal paste is said to have a thermal conductivity of 15.7 W/mK, which is higher than Thermal Grizzly Kryonaut, my typical paste. Also, this material was cheaper, so I decided to do some testing. My setup was an outdoor testbed with a Ryzen 2300x, 2x4GB Corsair DDR4, MSI B450 Max-Pro and a Zalman CNPS 10x Extreme Tower. Cooler. I ran five consecutive runs of the Passmark Performance Test CPU with both the TG connection and this connection and monitored the temperature with HWINFO64. I found that the Thermal Grizzly Kryonaut interconnect was an average of 2.2°C cooler at max CPU die temp and 2.0°C cooler at max motherboard CPU socket temp. The TG was also 2.0 C colder when idling. HOWEVER, the viscosity of Thermal Grizzly Kryonaut is lower than that of this SYY 157 blend. This makes a difference in distribution depending on the pressure on the cooler. My Zalman CNPS 10X Extreme CPU cooler has a fairly soft spring latch that secures it. It doesn't put much pressure on the CPU die at all, so I'm wondering if the SYY 157 connection would work better with a heatsink that puts more pressure between the CPU and the cold plate. (or maybe less?) Improvement, get a Thermal Grizzly. But if you're a GPU builder and rebuilder like me and need a quality, relatively inexpensive connection, get this SYY 157. It's really good stuff.
