So it's really hot in the UK right now and my temps are rising, and my 3570k is suffering from overclock degradation in general I think as my once stable overclock isn't stable any more, it constantly wants more juice. I was just wondering how good the stock fan on the Antec Kuhler is, and would buying a better one make a noticeable difference in temp? It's currently 50c idle at 4.3GHz @ 1.25 which seems high, and it can get up to about 77c while playing CS GO. I recently cleaned the fans and replaced the thermal paste.
