Will this do the job on an NF4 chipset?

 

[imported_Kensai]

Yes it will. Might not fit on all motherboards though.

 

[imported_meatball]

Yeah, I asked in the mobo forum if it'll fit on the EPoX NForce4 Ultra board.... But if anyone here knows, that'd work too. ;-)

EDIT: That'd be the EP-9NPA+ mobo to be exact. ;-)

It's cooling my Asus A8N-E well enough. On my board I find that it may interfere with your video card cooler if it's dual slot like the Arctic Cooling Silencers.

Works great on my A8N-SLI Deluxe, especially since it doesn't make any noise. Just make sure you have decent airflow across it and you'll be fine.

 

[feelingshorter]

as all NF4 mobos are really hot,...an active cooling would be better, im not sure that you are going to get it cooler than what you already have on your mobo. Even on my mobo with active cooling, its untouchable on the finger.

 

[mindwreck]

yeah teh nforces run hot. i tried to put an old socket7 heatsink on my nf3 250gb and it was burning hot

Ya, it was more an issue of getting rid of the fan on the mobo without losing any cooling.... The Zalman is SO much bigger than the stock heatsink with fan.

The stock active cooler on most motherboards is a piece of crap - often they are just a flat piece of aluminim with a fan blowing on them (that doesn't work very well)

I don't have an Nforce 4 board, however the NB47J dropped my Nforce 2 chipset 5C over the stock fan.

Good data point.

If you have enough airflow, you should be alright. I've heard of lots of people running their chipsets fanlessly (is that a word?) without trouble. I do, but it's with a swiftech mcx-159r (minus the fan)

This is so true for the A8N-SLI Deluxe stock HSF. I was amazed that the stock "cooler" was able to cool anything at all. The fan was too small to generate anything but minimal airflow, and the "heatsink" was nothing more than a flat piece of aluminum with thermal paste on it. The large fins on the NB47J increase the surface area of the heatsink multifold, and as a result easily equals the cooling capability of the stock HSF. I suspect it cools the northbridge much more effectively, but I don't have any data to confirm that assumption.

All I know is that my machine has been running rock solid since I installed it. So, it must be doing something right.

You can always add a little 40mm fan to it if it's too hot, but then it gets noisey.

If you have a 80mm fan (or better yet, a 120mm fan) at the front of your case, that should be enough to keep things cool.

Got one on my Asus A8N-E. Had to remove an entire row of fins and bend the rest to have it fit with the ATI Silencer 5 on my X800XL. But the good thing about that is the fan on the Silencer actually blows a bit of air right across it

So does that really work? I have the MCX159-R on there now and it's not that loud but any noise reduction helps.

Did you ever find out. I am going to try it. I have an antec p180 and it has a 80mm fan pointed right at it if I need it. Much better than the 40mm one that moved about 4cfm. That really doesn't do much. The Zalman may keep it even cooler.

 

[glorygunk]

Bought one for my nForce4 ECS A754 mobo...yes it does get untouchably hot. not sure if it's any better or worse than the original cooler.

how do you know what your NB temps are??

 

[IEC]

The Zalman coolers are high-quality and have good cooling, but only if you have good airflow - otherwise they heat up quite a bit...

I'm running the Zalman ZM-NB47J on an Asus A8N-E and found it to be way too hot for comfort... so I added a fan... check it out at my site here: Cooling the Zalman ZM-NB47J Northbridge Heat Sink

v.m

thats a nice way to mount but i think most people got the zalman because it is passive

anyone know if I can use the NB47J on the DFI ultra-d if i place the video card on the 2nd slot?

You may just be able to squeeze it in. You'll be forced to set the board to x8/x8 though as 16x/1-4x is too slow.

 

[ericlala]

is the top pci-e different than the bottom? i thought they were both same speed

There are only 20 PCI-E lanes total for the nVidia nForce 4 series.
It's normally x16/x1. When you change the jumpers on the board to SLI mode, it'll set it to x8/x8.

 

[ericlala]

i dont really understand what you are saying though
i am running 1 video card and if i just switch the slot, wouldn't the video card run at 16x still? or wil it just run at 1-4x?

It's physically configured to run x16/x1 at stock. Even if you use the second slot for your main card, it will be handicapped by x1 bandwidth.

You *need* to change the jumpers to SLI mode to get acceptable performance from the second slot. It will still be bandwidth limited on high bandwidth proffesional applications.
