Hello all. I will be using the i5-4670k and I do plan on OC'ing it to around 4.2GHz, or possibly higher. I am having trouble deciding on a heatsink. I was recommended the Silverstone AR03. After research I found something saying "The Argon AR03 is meant to be used on Intel sockets LGA2011 and LGA1366, as those CPUs have a large IHS. This allows for optimal contact with the heatpipes. CPUs that feature a smaller IHS, such as Intel's LGA1155 CPUs, will end up having two heatpipes that do not make full contact with the CPU, which results in lower performance." I am just looking for recommendations on heatsinks, or someone who uses the AR03 with the Haswell chip. The performance recordings for the AR03 are great and I just want to know if it will work. thank you
