Review on Thermalright TF8 Thermal Compound Paste: High Performance Carbon-Based Heatsink Paste, 13.8 W/mK, CPU Cooler Interface Material - 2 Grams with Tool by Brian Gopalan

I used this on an i9-9900k, a hot CPU, just to be sure. Radiator - Corsair AIO 240mm. The composition came out of the tube with a very liquid consistency, it didn't look like it was fully mixed as there was also a clear liquid inside. However, I applied a large grain of rice/small peas to the center of the heatsink and attached my cooler. Idle temperatures were a good 29-32C, but every load caused the temperature to rise, only running Chrome caused the temperature to rise to 60C+ and running a moderately demanding game like GTA V caused the temperature to climb and hover around 90 -95 °C remains C. This is on a stock watch, mind you. So I figured my cooler must have been installed incorrectly so I removed it, cleaned the CPU of the old paste, put a new one in and reinstalled the cooler. Same problem. I then tried an updated BIOS, which didn't change anything either. Finally. I switched the thermal paste to a different brand and the temperature under load dropped drastically. Now I'm playing GTA V (same game as before), my temp is around 63-71c on all cores. This is about what they should be for this processor. I had high hopes for the Thermalright TF8, it looks good on paper and may have encountered a bad batch, but its performance was definitely not acceptable to me.
