Today we will analyze a CPU heat sink by Thermalright: the HR-02 Macho. This is a giant heat sink that features a 140 mm fan. It has been created with the aim to further improve the good quality/price of the previous HR-02.

Test Results

As we can infer from the graph it is clear that we have a product capable of achieving excellent operating temperatures. We were really surprised to see that this brand new heat sink held off with an Intel Core i7 920 with well 130w TDP in a fanless configuration! This result is very remarkable. As you can see, the adoption of the bundled 140mm fan reduces the temperatures by well 13 Celsius degrees, all in silence. With the processor overclocked to 3.4 GHz, the situation starts to get complicated with a fanless configuration, otherwise if we use the fan it changes a little. Finally, at 4GHz the Macho still managed to achieve excellent temperatures being silent. These results leave no room for a lot of comments, they are undoubtedly very good performances.

From the standpoint of noise, we can say that it is practically nil. Here too the Thermalright HR-02 Macho behaved flawlessly.

Possible changes

As planned, you can install another fan in a push-pull configuration and we report that doing so it will improve temperatures of even 3-4 Celsius degrees. Unfortunately there are not additional bundled brackets so you will need to strive differently, for example through the adoption of clamps or brackets for assembly of different kinds and sizes. Generally, this configuration can be obtained simply by taking advantage of the rear fan installed in most cases.
