The chaps over at HWzone.co.il informed us they have broke the world overclocking record for QX6700 on air cooling! The Intel QX6700 CPU was taken to the unbelievable speed of 4241MHz on air cooling only.

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.
