Applying liquid metal tim to the radeon vii only lowers its temperature by 5 ° c

The famous Der8auer overclocker has returned for further testing on the AMD Radeon VII, this time to try to improve its operating temperatures with the use of a liquid metal TIM.

AMD Radeon VII is subjected to liquid metal

Replacing the heating pad between the Radeon VII GPU and its TIM with liquid metal reduced the maximum temperature of the GPU by about 5 degrees, and German overclocker professional Roman "der8auer" Hartung also observed a 24 MHz gain in speed. minimum clock.

This does not seem like a significant reduction in temperature, so we could conclude that it is not worth the effort, the money invested, and above all, the risk involved in doing this.

AMD uses a highly conductive Hitachi Chemical TC-HM03 Thermal Pad Strip. Based on vertically oriented graphite wires, the TC-HM03 offers a thermal conductivity of 25-45 W / mK, superior to most fluid TIMs on the market, including those based on diamonds. Conductivity and longer pot life compared to fluid TIMs is probably the reason AMD chose it.

The maximum temperature dropped from 106 to 101 degrees

Liquid metal is the best thermal interface material currently available on the retail market, but it requires very careful application because it is electrically conductive and can short circuit anything soldered to the processor. This must be why der8auer has used nail polish to protect the welds around the GPU matrix.

In conclusion, the maximum GPU temperature dropped from 106 to 101 degrees, and the minimum GPU clock increased from 1709 MHz to 1733 MHz. The turbo frequency, however, remained around 1, 780 MHz.
