new version of CNPS7000

[Icewind]

Love my Zalman for my P4, but I honestly wouldn't trust it on a Athlon setup, that new framing system is just to flakey...

Special care should be taken when moving a computer equipped with a cooler exceeding the weight guideline. Zalman Tech is not responsible for any damage that occurs when moving a computer.

1) Compatible if there is no motherboard component higher than 15mm in height (usually capacitors) where the clip is to be located (If interference occurs, the excess portion of the clip that interferes can be cut off to make it compatible.)

2) Compatible if there are four heatsink mounting holes around the socket

3) Compatible if there is no component with a height of 39mm or higher in the 55mm radius of the center of the CPU (e.g. power supply, graphics card)


Number 2 confuses me

The four holes are the same holes that the Alpha PAL8045 and Swiftech MCX462 and many waterblocks use.

Right, but the 7000A mounts on Socket 462 boards using clips over the socket lugs, it doesn't screw onto the board.

Yes, but why does it require mounting holes?

I'm pretty sure the 7000 is the one that requires mounting holes. The 7000A was specifically designed to fit on mobos without mounting holes, using the three-lug Socket A.

 

[RichC]

Sorry dude, the Socket A version requires the mounting holes as well. Most of the newer socket A motherboards (KT333+, NForce 2) should have them. The 7000A doesn't even touch the socket. See the installation diagram on Zalman's website.

This is a pretty expensive heatsink. It runs $42 retail, with tax and shipping, it may hit $50. That's an awful lot for a heatsink. Is the performance worth it? Or should I just put in some more cash and just get a watercooling unit?

 

[Icewind]

To answer that question, my 2.8 @3.0 is at 29c idle right now, and playing UT2k3 I was hovering at 36c, Not bad eh? And I can't hardly hear the Zalman

For water cooling, your going to be spending $250 MINIMUM on a good setup. I did it once and I didn't deem it worthwhile of the hassle, so I just aircool now

Can we get actual picture confirmation that the 7000A doesnt use mounting holes? I really want a definite answer.

Look at the drawings on this Zalman page. They clearly show the S462 version mounting with only the clip hardware, there's no "through the MoBo" hardware needed. There's a motherboard compatibility list there too.

Then why would they put a required mounting holes for a heatsink? I want a pic!

 

[merlion]

The Zalman site specifically states on its motherboard compatibility page as follows:

"If there are no heatsink mounting holes around the socket, CNPS7000A cannot be installed."

It also says this on the main CNPS7000A product info page:

"2) Compatible if there are four heatsink mounting holes around the socket."

 

[TheJTrain]

Looks like RalfHutter and merlion are right - there's a couple of bracket/standoff-looking things that go with it to mount it on a Socket A/462. After reading that Zalman page, I think I realized that I was confusing this with the new version of the Thermalright SLK-900, the SLK-900A - This one definitely needs no mounting holes. Sorry everyone, my bad!

But it specificially says "clip support for socket 462", as well as "2) Four (4) Bolts - For fastening the clip". What did you think was going to hold those clips on?

 

[michal1980]

i know they say u can't get it on an nf7/s v2.0
but has anyone done that? i don't see what the major porblem is with the board

 

[Afro000Dude]

It's out there for less than 40, and less than 35 at some places. Ya gotta know where to look (not on pricewatch).

 

[0roo0roo]

seems pretty sweet. how well do the 7000's compare with the slk 900 anyways? the 7000 series seems to cost less though, so if this new one costs around the same i'd probably go for it sweet silence!

 

[Tab]

I still want a picture

BTW Does the Abit NF7-S have mounting holes?

 

[michal1980]

i have no pic of it mounted to an athlon board right now, i've seen them

my abit version 2.0 has the holes, and
the german site hardwareluxx, mounted and tested the sink on the abit nf7/s board the results were suprising, because
it performed with a degree of the slk-800 using its much slower quiter fan. while the slk had a smartfan II blowing full steam to get the same result.

u'll need altavista to transelate, google didn't work.

the heatsink does not mount to the lugs on the socket!!!
u get 2 adaptor 'clips' which get screwed down to the mother board. (which is why u need the 4 holes)

then the heat sink gets screwed unto the adaptor 'clips'
the reason they say theres a tension bar like thing, is because thats what gets screwed to the clips u attach to the mobo.

also learned to get it to fit on the nf7/s u need to cut off an extra mounting hole on the tension bar. this is actaully allowed by zalaman, if u look at there instructions for the socket a u'll see a notice by it. there drawings are kind of hard to figure out but they work.
i'm out to order one and will let ya know what happens

 

[Tab]

Got a Digi Cam too?

 

[michal1980]

i'll see what i can do, i got a bad one , don't know if i can get anything better from a friend.

i'll do my best

Aahh! That's clears that up. You couldn't tell from the lousy drawings on Zalman's site though.

Has anyone tried this heatsink with the ECS K7S5A pro motherboard? I'm about to get one of those frys combos and would like to use this heatsink or a Thermalright. But I'm not sure if the motherboard has the mounting holes in it.

[TheJTrain]

Re: the K7S5A - some do, some don't, it depends on what version of the mobo you have. I've got the first version, when it first came out, before there were "Pro" and vX.0 versions. Mine has the mounting holes, but I guess the Pro doesn't. Check the mobo compatibility list on Zalman's website (link is down near the diagrams for the different sockets) and it'll give you more info:

hey update on the cnps7000a al/cu version (not all copper), on my abit nf7/s mobo, and the verdict is...
it fits woohoo.
just no pics but not really nessacery to get the point.
a number of modifications have to be made, and all are minor.

in the instructions for mounting the sink, there are 2 stand off's that are included and need to
be screwed to the mobo. they do not fit the nf7/s the way the instructions put it.

according to the isntruction the white one goes on the side with the caps, and blue on side with lever arm for cpu.

these must be flipped, with blue going by the caps, and white on the lever, u could grind the white one down.

the reason for this is the blue is smaller the white and so with the white being on the side of the lever, u cannot remove the cpu.

small mod number 2, the tension arm connecting the heatsink to the stand offs, is too long and will hit the caps.

fix, there are 2 holes on each side of the bar, one of which u can just deremel off, cut neatly and the arm fits perfectly around the cap. no caps are touched. downfall of this heatsink cannot be used on the new amd 754 sockets.

also if u follow the instructions and tigthen the heatsink bolts all the way down, ur motherboard will make a U shape,

it will bend, and quite a bit, i did this and got scared, surprised i did not crush the core however sink does rest on the 4 pads more or less so it was safe.

fix is simple just losing the blots about a turn each and mobo will be flatter, not perfectly but not a drastic bend.

last minor problem, on small cases ( i just stuck this into my new lanboy, hehe i like the case its got a classy sleak look)
anyway, u might hit the power supply, now in my case i was able to slightly move the power supply up in the mounting holes, however the grill for the fan got in the way so the grill got taken out.


performance, i went from a water cooling setup with a mcw5000a swiftech waterblock, a 88 camero heatercore, and a maxijet pump. so my temps with bios 1.7 were in the 40's always under load, 44.5C while encoding mepg's,
the case then was open so that might have enfluced the temps a bit but not much, right now encoding with the zalaman fan running on normal the temps is 50.5 degrees, so 6 degrees worse,


not dissaponted though, since now case is close, and as3 has not yet settled, i'm also missing an intake fan so thats gotta hurt temps by a degree or 2, i figure with the case being closed and everything now having the heat trapped in the case (120 ggig wd se 7200 hd, ti4200, some geil ram @ 2.8 volts,) thats alot of heat to get rid off.

upside is my overclock is still stable running prime for a number of hours while starting a video encode, and while copying a dvd to harddrive. overclock = athlon xp 1700 @ 180x11 @ 1.75 volts, i think this chip can actaully do more now since it's been burnt in.

more upside, my case is now closed, was never able to get water cooling to fit in case, so it was sitting on my desk. big pain in the but. also with no fans on my desk system is quite.
the smart blue 350w p.s. and my slow 2400 rpm 80 mm case fan blowing out make more noise, and the noise is air blowing out of the case, so its a very barely even midly pleasant 'sound' heat sink even with fan on it blowing full steam is ungodly silent.

also i will need to get a pic just because the site of the huge heat sink under the gently glow of the smart blue p.s. is very stunning.

more postives about this heat sink,. cooling of all extra components. with the radial desgin and the fan made to push are all around and threw the sink, all the power caps, power driver chips, ram and top of video card now get a breeze of air.

downsides, this thing is huge, don't know if on this board the passive zalman chipset heatsink would work. it also bends board, which if ur not paying attention too and screw down while extremly bent u might break something.
it also requires minor work to fit on nf7/s, which for newbies might be bad. however the mods are easy enough so that even a newbie should be able to easily do and start feeling confidant.

also board will have to be taken out to change cpu or sink, and it might not fit in some cases, however i think i fit it in a pretty smalll case, the antec lanboy.

all temp readings were down over a period of hours, (esspically the water cooling) with the a.c. in the apartment turned on @ 74F all the time,

if andtach or anyone else wants me too clean this up post up and turn it into a real product review i'd gladly do it. if anyone wants to send me a copper version, i'd slapp that on and compare the too. lemme know

email me @ olechowm at msoe.edu

thanks guys, let me know if u have questions comments.
sorry i know its rough i just had time to sit down and actaully type instead of running primve, xmepg, or memtest.

peace,

michal

I got mine for $35 at Fry's a few days ago and I want to run it on an Asus A7N8X Deluxe motherboard with an Athlon XP 2500+ that I am buying this Monday. Hopefully it will allow me to overclock to 3200+ or higher speeds. I can't wait
