PC Modding Malaysia posted a review on the Thermalright HR-05 Chipset Heatsink

Overall, the Thermalright HR-05 is an impressive chipset heatsink. Thermalright did the right choice by following the foot steps of the High-Riser series and the result speaks for itself. Although the size of the heatsink is massive, we couldn't believe how easy it was to install. Furthermore, it was designed to work passively but it is also possible to install a 70mm or even an 80mm fan on it. When tested passively, the HR-05 was way better than the stock cooler and it was still a solid 11=BAC cooler when overclocked.
