Thermalright is a name most hardware enthusiasts associate with quality, innovation, and clever design. My introduction to them occurred during the heat wave that was summer 2005. I was running my main box with a 50% overclock in a home without air conditioning. After trying a number of different, unsatisfactory solutions I purchased a Thermalright SI-97 heatsink, attached a 92mm fan, and thankfully found that my peak temperatures had lowered back to a reasonably tolerable level. I was impressed with the performance of such a light and easily mountable heatsink. Fast-forward to today, I’ve been using the recently reviewed Antec P180 case. While the case has many merits, I’ve been craving less noise while at the same time eyeing the placement of the two fans that frame the CPU mount. As soon as I saw the HR-01 I knew I had to try it out. It seemed to me that it would be a perfect match for the P180. In this article I’ll be looking at the performance of this assembly with regards to both stock and overclocked performance using an Athlon 3800+ X2 CPU.
