There is no need to use a 140mm fan in order to cool your cpu quiet. You could easily use a good 120mm model, even Hyper 212 + Nexus fan would be completly sufficient at no oc.
Even with overclocking, 120mm does a better job of meeting suchageek's needs. 140mm fans seem like a good idea, but the 120mm fans generally come with better sound/performance envelopes. And they do better in high impedance situations, like heat sinks. I recollect a number of times that the 120mm Nexus has out performed 140mm fans, in fact I don't recollect a time that they haven't. And even in the recent SPRC fan testing, they were upstaged not by a 140mm fan, but by the 120mm Scythe GT.
If suchageek is looking for something under $60, that rules out the Noctua NH-D14. In fact if you take into account fan costs, almost all the good ones are just a bit over $60. The $60 requirement rules out so many alternatives. It sort of leaves only the Scythe Mugen or the Coolermaster 212 (swapping in a nexus or Scythe fan bring the coolermaster cost up as well)
So if suchageek wants reasonable size, it is the Coolermaster 212. If she wants lots of cooling, then it is the Scythe Mugen... both of which use 120mm fans. That $60 limit screens out a lot of options.
Don't forget that you just don't need that much cooling, even for an overclocked CPU, except when you are running benchmarks or such that put a heavy sustained load on the CPU. You do want enough cooling capacity to prevent things from cooking if you have an unobserved runaway process, but the Mugen and probably even the Coolermaster can do that.
For example, here is the cooling performance of the coolermaster under a 150 watt load:http://www.frostytech.com/articleview.c ... 655&page=5
It runs only about 1.5 C hotter than the NH-D14. Benchmarks seem to vary a lot from site to site... but not that much. Put a Nexus or a Scythe PWM fan on it and you have something there.
I am just not seeing anything else out there, other than these two, that meet suchageek's needs for under $60. I see nothing with a 140mm fan that does. Am I missing something?
