Well my overclocked rig idles at 40 and under load gets to 55. im running a Zalman cnps7000alcu with the fan all the way up (2400). Temps are high for me, so would this help gimmie some what better temps? An sp-94 with a Vantec Tornado 92mm fan? im too scared to use the hyper 6, things 2 lbs? heck no way im using that, and it uses clips? Get outta here with that thing. And i dont wanna hold off untill the xp-120. So does the sp-94 seem resonable? Yea the fan will be loud with that but sounds isnt a problem with me.

I used to own a Tornado. Now I am deaf.Circaflex said:
I tried running it at 7v, but it had a very annoying whine. Have you ever heard a tornado? I'm using the 7000alcu now, and my temps are almost the same as yours. IMO, as long as the system is 100% stable, temps dont matter. The SP-94 with a high CFM fan would cool the best though. Ever consider watercooling?BTW, the max lines in a sig should be <10.

SP-94 with this fan should do the trick. That Tornado is way loud for my taste. But really, your temps aren't that bad.
Unfortunately, you would have to put up with an extremely high noise level with the Tornado fan - in fact, so loud that your ears will be ringing after just a few minutes. It's not worth that huge noise increase just for moderately better cooling performance, IMHO - and what makes it needing such a loud fan is if the HSF is exceptionally inefficient or poorly designed to begin with (Most old-style coolers fall into that category.). And the only time that Windows may become unstable with a Northwood-core P4 would be if the core temperature is allowed to shoot up to over 60°C under load.Circaflex said:
As for your Zalman CNPS7000-AlCu, it is not the best heatsink for your overclocked CPU. However, it does a better job of cooling slightly overclocked CPUs than many much noisier heatsinks on the market. You'd probably want expensive watercooling if you want to overclock anywhere past your current overclocked settings - even the heaviest heatsinks with the noisiest, loudest fans can only provide a modest improvement in cooling performance over your current setup.
And according to Zalman, the only difference between the CNPS7000 and the CNPS7000A series heatsinks is the "A" version also comes with mounts for Socket A AMD CPUs, in addition to the mounts for Socket 478 Intel CPUs and Socket 754/939/940 AMD CPUs that are common to both models.
SP94 is a great sink. I'm using it now with a 92mm Sanyo Denki 55 CFM fan and getting acceptable temps. I was using the Zalman before, same one you have, and noticed much improved cooling by switching to the Thermalright. I think the only air cooler that will beat performance from this sink right now is the 2-lb. Cooler Master you mentioned.
For reference purposes, just to get an idea that noise isn't everything:anr11 said:
The stock Intel cooler is noisier/louder, and it still doesn't cool as well as the Zalman. A relatively inefficient heatsink design is to blame for such underwhelming performance.
