I actually agree that the Thermalright coolers are the way to go. I happened to have a Zalman laying around from an older build, so I used that but I have read time and time again that the Thermalright coolers are the best in terms of superior temps. I would have switched to this cooler but it is so tall that it is within 1-2mm of not fitting in my case, so I don't want to risk buying it and having it not fit.

Even when switching to liquid cooling, I was unable to get a better overclock than I got from air cooling using Thermalright Ultra 120 eXtreme. http://www.thermalright.com/new_a_page/product_page/product_cpu_cooler_1366.html That was almost 2 years ago, but they were unbeatable then, and one heck of a lot cheaper than all the $$$ that I poured into liquid cooling! However, I did have a lot of fun putting together the liquid cooled system ;) Mike --- In [email protected], Paul D <notanaiqgen...@...> wrote: > > Hi Rob and other system builders, > > In 2009 I built my own i7 920 and overclocked it to a very very stable 3900 > megahertz.
