Guy broke the record with an Intel Core 2 Extreme Q6700 processor (QX6700), Intel's quad-core CPU, with each core running at 2.66GHz at stock - making it a particularly hard nut to crack. With Guy's expertise, the QX6700, along with the ASUS R.O.G Commando motherboard, cooled by nothing but air, reached a maximum (non-stable) frequency of 4241MHz - at this clock speed the system was so unstable that even taking a screenshot was impossible and we had to take a photo of the screen with a digital camera. The maximum stable frequency which allowed us to take a screenshot and even get CPU-Z validation is 4171MHz - a world record for an air-cooled QX6700.

This amazing achievement was made possible with ThermalTake's BigTyphoon, to which we added two additional 120mm fans, on top of the existing fan. Bringing the QX6700 to such a high clock speed required a very high voltage of V1.735, with an enormous loss of V0.115, but the temperatures remained within the reasonable range - up to 75c under full load.
