Which one? Zalman ZM-NB47J or ZMNB32J ?? For Dfi Lanparty Ultra-D nf4 w/ 3ghz opteron

I recently got an opteron that does almost 3GHZ :woot:

However, at 290, the chipset fan is LOUD :eek:

I was thinking of passive cooling, will that work? :confused:

according to this archieved thread

something like this is possible:

http://img154.echo.cx/img154/5084/zalman6bw6po.jpg

Willl that do? Cuz im now at 46c :nono:

I need help picking which cooler?

The Zalman Gold ZMNB32J ?

http://i15.ebayimg.com/02/i/05/64/be/f7_1_b.JPG

or the Zalman ZM-NB47J (blue one) ?

http://i9.ebayimg.com/03/i/05/6b/45/fc_1_b.JPG

Or do you have your own recommendation? :help:

it isnt passive but its not terribly loud: vantec iceberq

Ah yes, i have the same problem.. i dont have all my kit yet.. but i have an ultra-d here and man its fan was loud compared to any of my other fans.. I also got a ZM-NB47J, but i haven't mounted it yet because i'm not sure yet how to bend it because i don't have my 7800GTX yet.. and come to think of it.. i wonder if it would even fit, the GTX is a very long card...
I don't mean to thread jack, but does anybody have any pics of a 7800GTX on a DFI NF4 board to see how far it sits over the nb fan?

Im not buyin his $50 chipset cooler.
I can do that myself, but I dont know with what...

But, should I go with the blue, or gold Zalman?

I'd say the blue one as it's got more surface area.. it's taller.. but they are both too tall to fit under the video card so you have to bend them anyways.

I found out that copper is the best material to take heat away and aluminum is the best material to release that heat into the air. SO it depends but I personally would go with gold if airflow and blue if not a lot of air flow.

Zalman ZM-NB47J (blue)

Dimensions 37 (L) X 37 (W) X 47 (H) mm
Weight 54g
Material Aluminum

ZMNB32J (gold)
Dimensions 37(L) X 37(W) X 32(H) mm
Weight 36g
Material Aluminum

So, the blue one's pins are taller, but surface area is same...

Get the blue one then.

I'm here, thats my mod on the first post :)

Go with the blue ZM-NB47J its easier to bend into shape as its aluminium and does a fantastic job. Aluminium is the better material for a low airflow situation such as this too I believe.

I PM'd you back about temps, with my Zalman I idle sub 30 degrees and hit around 35 load with 1.6V Vchipset, thats with a 92mm fan running silently blowing on the PWM and chipset area. Beforehand I was hitting into the 50s with the stock chipset sink.

Configure SmartGuardian to lower the chipset rpm a bit.

Mine is at about 44-45ºC idle, at fan spins at 2800-3000rpm.... for me its inaudible.

In summer was at 48-49º and about 3500rpm

Just rise the maxrpm temp in SmartGuardian to 58º, or play a bit with the threeshold bar to get the rpm where you want.

salu2.

My MOD

Well, I'm not nearly as good as Minstadave
But.. I tried :cool:

http://i21.photobucket.com/albums/b2...9/IMG_1908.jpg

As you see, it's not nearly as neat.
The reason is because I installed it before bending it :slapass:
So.. I had to carefully bend it while mounted :slap:

http://i21.photobucket.com/albums/b2...9/IMG_1906.jpg

When I was trying to get the f:banana:ing push-pins in, I sliced my thumb on the heatsink :clap:

http://i21.photobucket.com/albums/b2...9/IMG_1907.jpg

The video card (connect3d gto @ 16 pipes :toast: ) didn't quite fit in without touching the heatsink.
Now, I'm not an electrical engineer, but as far as I'm concerned, putting metal to a circuit is usually unhealthy.
So I put a layer or two of good ol' electric tape on.

Well, that's pretty much it, same temps as with stock, so I now have a system fan that kicks in after 40c

pics of it installed? and what are your temps now? thanks

^don.k's^

I have a swiftech mcx159r, but on my expert, i'd say isn't enough that zalman to cool pasively the chipset, cos mine gets to 48º, buy i touch it and it looks way hotter... :stick: BTW i have a vf700 near who cools it to 42º at low rpm's...

I think which if i'm having problems with a better cooler than yours, you won't be able to cool it pasively, but you maybe have your vga throwing air to it, so then would work ok, but not 100% passive though. :)

BTW wth were you thinking of to blend the cooler mounted on the board!?!?!?! You could have damaged your chipset easily... :nono:

I bought one, but im such an idiot :stick:

These are impossible to mod enough to fit if you own an arctic silencer!

:mad:

The arctic silencer hangs so far off the back of the card and means there is no where for the fins to be bent to.

Ah well, only £8 :rolleyes:

snap some fins off here and there. That sure will do.

GET THE BLUE ONE
i installed the blue one a few days ago, my chipset idles at about 36, down from 39. and the loads during games get no more than 42 but i havnt primed for a while lately so i cant tell u for sure.

if u have a dfi nf4 ultra/sli and if your using just 1 video card, then just move the vid card to the 2nd pci-e slot and it will work just fine, no performance loss and the heatsink fits just fine.

I think i'd have to take 2 rows roughly tho

And I did snap some!

Temps are low <40c in winter at stock, with open case, no fan is needed. Hotter seasons/overclocked (300fsb), Need slowspeed fan, like I have the vantec 120mm blowing on it thru the gpucooled radiator:

Same, but I had a spare 9200SE heatsink around, so I used that instead. :woot:

Temperatures are worse then stock though, 63C was the max reached so far.

Keeping in mind this is with the Opteron 165 in my signature. :clap:

When you want better.

Grab this when it is back in stock Copper is MUCH easier to bend.

Pin bending:
Get Stiff 1.5" wide putty knife so you can bend a row @ a time.
Do it right, do it B4 Mounting, do a dry mount and check vidcard clearance. Only had to cut 2 pins

Wifes Pc chipset temp - 41c doing rosetta (DC opty) Best setup of my 3 DFI board by 2c. Only cooling is from the zalman VF-700Cu fan on the vidcard.

Man, that is pretty terrible to see, you could have just moved the card to the lower slot without destroying the heatsink as I did on my board :D
03-16-2006, 11:27 AM

The lower slot is at PCI-e 8x max ;)
Not a big hit at all though :D

Yes, it's only up to 8X but it doesn't affect performances at all because the 8X slot's bandwidth is enough for (I think) any card :)
I'd rather move a card to the lower slot than destroying an heatsink :D

16x is faster than 8x isnt the only reason

the top card has a shorter bus to the rest of the system

Do you actually think the longer trace would affect the performances? In electronics a signal is usually considered to take zero seconds to be transmitted and received when talking about such short distances.

for one signal, but not when you consider it as a whole.

It's not lag, but it does decrease performance overall.

why do u think the ram is in the orange, rather than yellow slots in the dfi nf4 ultrad ;)

I never considered the distance factor, I put the RAM in the yellow slots in my board because they are #1 and #3 slots. Did anybody prove that putting it in the orange ones makes the system faster?

anyone tried the arctic cooling chipset cooler?
looks to be around the same price as the blue zalman

+ it makes a difference with crossfire, when u use topcard as master, bottom slave, and crossfire on SLi board

Haha, but that's $65AUD compared to the NB47J's $11AUD. :slap:

I have a similar problem, my MSI K8N SLI platinum's nForce4 chipset cooler makes such a terrible noise.. now I have a Zalman NB cooler (the blue one).

BUT

How should I install it? The problem is I use a Arctic Silencer on my X800XL (in fact, it was already installed, it is a HIS IceQII :)). Of course the Silencer's fan is right on top of the chipset cooler. To install that Zalman I have to a) shorten the heatsink thinks, so cut it off to almost the bottom of the Zalman block and b) bend a few of those things, but I think i have to cut off most of them.

Maybe I should use the second PCI-E slot? IS THIS POSSIBLE? Do I have to turn the switch of that SLI thing on the mobo?

Any response would be greatly appreciated :)

I don't think the heatsink would fit by moving the card to the lower slot because of the board's layout, unlike DFI nF4 boards yours has the nF4 too close to the second PCI-E slot and so the video card would still collide with the heatsink.
