TweakTown uses a different method for testing CPU heatsinks which allows for an even playing field across all product tests. We feel that by using the same ambient temperature and strict lab-like testing procedures we are able to accurately compare one product to another. More information on our testing procedure can be found in the T.E.C.C. article here.
The decisive moment for the ThermoLab Micro and with our high-end processor simulation; the performance was quite poor. The heatsink was not made to take the abuse of flagship 120-watt processors, so I expected these results. I was very disappointed to find that the cooler was not able to surpass the numbers put up by the stock Intel cooler.
When it came to measuring the acoustic foot print, the ThermoLab cooler was quieter than the stock Intel unit most of the time when running at idle and low loads. On the load test the cooler just couldn't keep up with the coolers that had more mass and the fan needed to kick into overdrive, producing more noise than the stock Intel cooler.
