Zalman CNPS7000 Cu

Post by DraGoNsLaYeR » Fri May 07, 2004 7:29 pm

I am going to be getting the Zalman CNPS7000 Cu heatsink. I was wondering if the supplied thermal paste was good enough or would I see any differences if i bought a seperate Arctic Silver 5 and used that instead

I have a CNPS7000 Cu and I'm using the Antec silver compound. I actually never checked the HSF's included compound, but chances are it's not the best quality, and probably not even silver-based (I'm too lazy to go check it out, so if someone could verify this, thanks). You might see a slight difference in temps, which may or may not be important depending on your CPU speed. But for the extra $10 or so, you might as well get some Arctic Silver.

yep, it basically boils down to if you have extra money to spend. If so...go for the gusto! :lol:

The supplied compound will work just fine.

Pardon the dumb question but is the 7000Cu version better than the 7000AlCu version?

Yep - Copper will disperse heat better than Aluminium - but Alu is cheaper. Copper better, costs a bit more. Worth it tho :)

The results from MikeC's review of both heatsinks is that the AlCu actually outperformed the all-copper Cu version by a few degrees. Even if it didn't, I'd go with the AlCu version anyway. There's no reason to hang a heavy lump of copper off of your mobo if it's not performing noticeably better than the safer (and cheaper) AlCu version.

Thanks for the confirmation guys (guess I should have read the review first :wink: )

I noticed this in the review
The same can be said of the differences seen between the AlCu and Cu models. They are essentially indistinguishable in performance with the P4-2.53 in this ambient as well. Certainly, the Zalman 7000 HSF has no problem cooling a P4-2.53 even at minimal fan speed settings. One suspects that with the very hottest CPUs or with higher ambient temperatures in a system installed normally inside a case, the copper version would perform better that the AlCu, especially with the fan at low speed.

I have a P4 3.2 so I think the CU version would be better for me. I guess I'll get the artic silver since its not too expensive and probably can't hurt.

I was lucky: the Cu was the only version this particular retailer had, but it was only $34! If I could've gotten the AlCu though, I would have due to the weight difference. My motherboard seems to be handling it okay, however, with most of the available screw holes in use :wink: .

A place called Lion Computer. Their website doesn't sell it, unfortunately, so if you're not willing to drive to their store in northern-Illinois, you won't be able to get it at that price very easily :( .

2.0 Celeron? Why don't you just take out the fan on that 7000? That heatsink should be enough to cool that CPU as long as you have a rear exhaust fan or something.

Nope, as silly as it seems the 2.0 Celeron puts out about 52W, too much to be passively cooled. People think that since it's such a gutless CPU it doesn't put out much heat. :)
