Success in removing the heat spreader cover from the processor AMD A4-5300 (Trinity) inspired our Japanese colleagues on a closer examination of the topic, and today appeared a more detailed study, in which regular thermal interface separating the cover and the crystal nucleus was replaced with more efficient thermal paste from other manufacturers.
Once again, remember that removing the cover from the processor results in permanent loss of warranty, and the event itself may end with damage to the processor with the loss of their efficiency.
The temperature measurements were made in a system with an A10-5800K, which is cooled by Thermalright Archon SB-E X2. Regular thermal interface after removing the cover from the processor was updated to OCZ Freeze Extreme, and then to Liquid Pro.
At a frequency of 3.8 GHz processor under load with the standard thermal interface heated to 76 degrees Celsius, with OCZ Freeze Extreme - up to 70 degrees Celsius, with Liquid Pro - up to 67 degrees Celsius. Overclock to 4.2 GHz with the core voltage 1.362 increased the gap with the standard thermal interface to 9 degrees Celsius in the case of OCZ Freeze Extreme, and up to 13 degrees Celsius in the case of Liquid Pro.
Finally, clocking up to 4.4 GHz with a core voltage 1.45 V retained the difference between alternative thermal interfaces at 4 degrees Celsius, but increased the gap with the standard Liquid Pro thermal paste to 15 degrees Celsius. The conclusion is that the regular thermal interface of Trinity processors has mediocre performance.. Related Products :
