Jayztwocents talks about the safety of overclocking a CPU and GPU/Video Card and I completely agree with the points he mentions here. My personal system is a 2700k at 4.8ghz for over 4 years now and still rock solid. Give Jay a follow on YouTube if you enjoy his content.
JayzTwoCents just released a great overview video of the benefits of overclocking and the different methods of doing so. XMP vs Auto vs Manual. When I overclock a system I prefer Manual, what do you prefer?
Jayztwocents puts the Corsair H100i against two popular expandable liquid coolers. While the swiftech model is no longer available in the USA, the EK unit is. Needless to say, both styles are good choices and it comes down to what you want out of a system.
