One thing I found surprising was the fact that this processor ran relatively cool for having six processing cores when air cooled and even more so when put under water. The DBX-B cooling solution from Intel is a radical step away from what has been done in the past when it comes to OEM solutions. Its copper/aluminum construction is similar to many higher end tower style heatsinks on the market and performs quite well by comparison. With four heatpipes there is no shortage of thermal capacity. Even when pushing up to 4.05GHz the temperatures stayed for the most part in the high 60°C range. However I did notice some throttling of the core clock speed once temperatures reached 70°C.
