I used that Zalman it came with the HSFkill4killin said:I just got the same cooler for my AMD Opteron 148 and it helped me a bit. It wasnt as dramatic as i would have liked, but it keeps my 2.8Ghz Opteron idling around 35C most of the time. I have a 120mm intake and a 120mm exhaust with an 80mm side fan to keep things cool and am planning on adding some kamas into 2 of my free drive bays to help push more cool air into the processor since my intake right now goes mostly onto the HDDs.
What therm paste did you use? I recommend AS5 if you havent used it already, it helped my stock cooler as well as my zalman. Another thing you could consider trying is lapping the hs but idk if that will have that big of an impact. For the kind of cooling your looking for, i would recommend the Sythe Ninja or if you want to stick with Zalman check out the CNPS9500 AT, i know that it cools better than the CNPS7000. You might also wanna take a look at the Thermalright XP-120, i have heard good things about it as well.
You could also try the CNPS8000 But i havent heard anything about it, but it looks pretty good with its numerous heatpipes.
That is where you are wrong the 9500 is one of the top performing hsf's out there. How did you install it? what thermal paste how much thermal paste etc?velusip said:Zalman's don't really help in that regard. They help keep things a little quieter, but that's about it.
Look into streamlining the airflow into and out of the case to reduce ambiant air temps. Recycling warm air back onto the processor doesn't do anything for you.
