cooler for a quad cpu

[subzero]

Just had a Q6600 and now i need a cooler as i bought an oem chip,i have a chance of having one of these coolers..

Zalman CNPS9700-NT nVidia Tritium CPU Cooler..

Is this a good cooler,would it keep my temps down if i overclock the cpu a little.

What sort of temps are acceptable with these quad cores,obviously they will run hotter than single core,but im not sure what acceptable for a quad core..

In that price range, the Thermalright Ultra-120 Extreme is king! Alternatives would be Noctua NH-U12F & Tuniq Tower 120/120-LFB
