Hello, I want, from people who tested/own a quad core (Q6600/Q9450) a cooling solution. No liquid and fanless solution. Also the silent the better, silent under heavy load, let's say 40dB max. Price can reach 150USD. I've read many reviews but still can't decide what to get that's why I'm asking advice from people who use such cooling solutions. In my list is Scythe Zipang, Scythe Infinity, Xigmatek HDT-S1283, Noctua NH-U9B, Zalman CNPS-9700-LED. Room temperature is 20-25C. [email protected] max, [email protected] max. I don't want to keep the system stressed 10x in advance, hope I'm not too picky!
