Which Zalman?

I have a P4-2.6C with retail HSF on an intel motherboard. So overclocking is not an options for me. My case and CPU are all running at about 29-30C. I want to put in something quieter, and I keep hearing about Zalmans. So they have the NCPS5700D, 6500A/B and 7000/A with the latter three coming in both AlCu and Cu versions.

I like the 5700 and 7000 for their simplicity. So my question is whether there's any difference between the AlCu and Cu versions of those coolers? I know that Cu cools better, but if my computer currently running at 29C and not getting overclocked, is it worth the extra cost of all copper?

One more thing. With a 92mm fan, will this fit inside the Sonata case? Looks like the spacing might be a little tight.

Cu are better than CuAl, that is a simple one. Not by much but still better. 5700 is a small heatsink and you'll have to use a bigger fan since their 3000 RPM fan is too little to cool 3.0+ GHz. The duct is a gadget. It is better to reverse the fan than to use duct. I'd go with 7000, that is an easy decision to make.
Or even better to go with Thermalright since that way you can choose what fan to use, and anything like 800 or 900 is better than anything Zalman makes.

I'm currently using the Zalman 7000Al-Cu HSF on my P4 2.6c with temps running at 39c idle and going to 46c a full load. THis is with the HSF directly connected to the mobo without the speed control.

I initially was going to purchase the 7000Cu however when I looked at the weight, where it exceeded the max. weight allowed by Intel on the P4.

FYI: The 7000Al-Cu is extremely quiet.

I'm using the 7000-Cu on a P4 2.4C @ 3.1 GHz (I know, this chip *should* be able to go higher.. I got a bad one). Anyways, temps are insanely low - 27-29C Idle, 35C load.

Not with the Zalman 7000. The tests here show differently:

Cu versus Al-Cu

Any significant difference between the 7000-AlCu and the 7000A-AlCu? Or is the assembly just different to make it fit more CPU's?

The "A" version is physically identical to the original "non-A" version except that it has additional mounting hardware included in the box that lets you use it on Socket A precessors too. The original "non-A" version only fit on P4 (Socket 478) boards and Athlon 64 boards.
