I've read the SPR review of the NH-L9 and want to know options if it is too risky a choice for the AMD-5800K with socket FM2, esp. if you give it a modest overclock at all.
Noctua says the NH-9Ls are for up to 65W TDP for AMD but has a qualification that leads me to believe that I could use it with the nominal 100W TDP 5800K which idles at about 43W. The qualification is here:http://noctua.at/main.php?show=nh_l9a_tdp_guidelines
3) Our recommendations assume that the fan is used with PWM control (configured so that it can speed up to 100% when necessary) but without the supplied Low-Noise Adaptor. If you would like to use the NH-L9a with the supplied Low-Noise Adaptors, we recommend choosing CPUs with less than 65W TDP.
The SPR NH-9Li review used an overclocked 95W CPU and did quite well.
I will be building a new system. I live in a relatively cool climate so meet the below 25 degree C ambient guideline. I am thinking of using the Silverstone Temjin-TJ08E case with excellent cooling along with an ASUS F2A85-M Pro MB.
If folks think my idea is too risky, not likely to be quiet, etc., please suggest an alternative cooler.
