Hey guys, need a favor, would anybody be willing to sell me their original NB cooler? Mine died yesterday and I just want to replace it with another original, and also it would be nice to avoid the whole RMA process?

PM or E-Mail (See sig.) me if you would be interested. I can send Paypal.

Thanks.

Just contact the company...they should send you a new fan. I requested one from MSI for my NEO2 and they sent me one from their video cards...told them what happened and now they are sending me another one, hope it's right this time.

I'm getting a Zalman ZM-80D passive VGA cooler with the NB47J tomorrow and I hope they work together. Has anyone tried before? I am starting to wish that I got the VF700 instead since a few people have gotten them working together. Is the VF700 very quiet? I hear Jab-tech is nice about doing RMAs maybe I should just get a VF700.

Edit: I'm going guns out on this one. If it works a few people will find it useful, if it doesn't I'll let Jab-Tech charge me restocking and move on to a VF700.

What about the chipset fan plug on the mobo? If you swap out to a lower RMP fan, will it work?

Silence is beautiful... Replaced the loud pos chipset fan today with a Zalman NB47J.. My idle temps for the "Motherboard" went from 32c to 26c... The heatsink isn't even warm to the touch... Works beautifully!!

Let me know how that works out. I will be doing the same whenever my tax refund comes. I'll probably wind up severely tipping the angle of the NB47-J or cutting some pins. Again let me know please.

Also, if you put in a Zalman, do you just put some gel on it first?

I'll let you know tomorrow if everything works out. I can't sleep right now just waiting for my parts to get here and I'm reading every spec and looking at every picture I can to speculate whether it will all fit. Tomorrow we'll know for sure.

hehe good luck!

From what I've seen picture-wise, i'm guessing that it will fit with the NB47 skewed into diamond form on the chipset. I hope I'm right If not it's dremel time and the NB47 is gonna get a few fins clipped hehe.

Great news!

I'm using a A8N SLI DELUXE motherboard with a NB47J Northbridge heatsink mounted. Futhermore i'm using a VF700CU on my ASUS Geforce EN6600GT without modifying any of the fins on the VF700CU or the NB47J - There are more than 5mm space between them. I've taking pictures of it - But where can I post the pictures ?

Great noiseless combination

Thanks for all the tips!!!

I'm using the VF700 in silent mode (5V) and the 6600GT core is still 7 degrees lower than with the stock cooler

I can't barely heat my machine anymore - Only thing to change now is my Cheiftec PSU

 

[runestone]

ptr, try a google for free image hosting. I'd like to see some pics; the fan on my Leadtek 6600gt is too loud. How was install of the Zalman on your card?

 

[imported_ptr]

It was quite easy and fast

Do you have a link to the upload function at google ?

It worked out fine. Right now the heat pipes touch the NB47-J but all it takes is a little piece of string or dental floss to suspend the card up a little bit to give it a little gap. I'll post pics tomorrow. Overall this thing is flying with an XP-120, NB47-J and ZM80-D all installed today.

EDIT: One thing I have to say is that SLI doesn't seem to be a possibility with this setup though. You could probably put a ZM-80D on the top card and a VF700 on the bottom card because if you put the ZM80-D on bottom card the heat pipes will obstruct the NB47-J. However it looked like it would clear an NB32 though. Right now I get 40C temps on the MB reading (whatever that is supposed to be since there is speculation whether that number in Asus Probe represents the NB).

 

[Interitus]

Very good news! Please post pics as I'm very anxious to see them. I already have an NB32J so maybe that would clear the ZM80D ok.

Glad it worked for you!

 

[GodLovesPunk12345]

Ptr, does the Zalman fan also help cool the NB47-J? It looks like its in a way where excess air could blow onto the heatsink and help cool it a bit. Let me know.. I'll soon have this quiet combo.

 

[runestone]

Thanks for the pics ptr; I'm thinking of trying that zalman. Going to wait until the Arctic Cooler comes out for the 6600 and see how it works.

 

[imported_ptr]

The stock cooler was blowing air on the NB47J - But the VF700 in silent 5V mode isn't cooling the NB47J much - I'm planning on using a 80mm blower in silent mode to cool the NB47J from the side to compensate.

HOLY CRAP :shocked:

That's about as tight of an install as I've ever seen! Looks promising for me though!

Thanks very much for the pics!

sxr7171 - Thanks for the pics!

I have a suggestion if you still have it apart. From the look of Pic7, the lower heat pipe easily clears the top of the lower pins. You simply need to turn the NB47J 90 deg clockwise to have it not touch at all - the same config as mine (less the skew). Look at it from the side and I'm pretty sure you'll see what I am. I'm also guessing you would get better efficiency from the NB47J in a rotated config to since the air coming off the Zalman fan is going to dispurse radial from hitting the motherboard, and allow less resistance.

I know this second suggestion may sound like I'm smoking crack, but what is the harm (besides being conductive) in letting the sinks touch? My thought is that excess heat (given the pipe is cooler than the chipset, would transfer heat away to the pipe... Just a thought.

I sure wanted to go this way with mine but your pics confirmed what I already knew. With people that have GPU way back on the card like the Quadro 1300, you can't fit the main heatink by the chipset heatsink in a million years.

Can you imagine what it will be like with SLI and 2 cards?!!! I'm actually very pleased being a first time builder. It really is a testament to Zalman for their excellent instructions and even though ThermalRight's instructions weren't the best their design was awesome and made for a far easier install than it looks.


I'll try to get some more pics of it in the case.

One thing I forgot to mention is that little Molex power connector that sits above the video card for extra power for SLI setups is pretty much inaccessible with the ZM-80D on there. There might be a short Molex connector out there that might work though.

sxr, do the heatpipes on the Zalman interfere with ram installation?

I might have to do just that when I have it apart next time. I was actually worried that the front heatsink of the ZM-80D was going to touch or obstruct the chipset block. It turned out that it was the heatpipes that were the problem. I actually have two 120mm case fans one at the front bottom and one at the back. It looks even more crazy in the case with the case fan almost touching the Panaflo on the XP-120. The case fan at the front blows a good deal of air on the chipset sink. I actually agree that turning it on the side would allow for better air flow though the fins of the NB sink and even better airflow thorugh the system.

The Zalman fan is the noisiest fan in the system when run at 12v, but when run at 7v the Panaflo at 12v takes over as the noisiest. The Zalman at 7v is pretty slow and I don't think it can really throw air with enough force to cool anything but the ZM-80D. At 12v on the other hand it is pretty powerful.

I never really thought about that until you asked. Anyway, I took a look at my machine and I guess you'd just have to pull out the card to be sure that the heatpipes aren't in your way. You might be able to pull out the RAM without removing the card but I haven't tried. The surprising thing for me is that the XP-120 does not block the first RAM slot. So changing RAM won't involve reinstalling the CPU heatsink.

As far as I've seen, the two things that you will lose are the PCI-E 1X slot next to the card and the ability to plug in that extra power connector for SLI. I'm not sure if that extra power is absolutely necessary to use SLI, but if I remember correctly it isn't. One thing is that might have been possible to plug in the Molex connector and then install the card but I'm not sure. Maybe there is a low profile Molex connector that will do the trick.
