DFI Ultra-D NB fan too loud? What are alternatives?

In my quest for a quiet PC, I recently ran into a new speculation about noise when people tell me the northbridge fan on the DFI Ultra-D is screaming loud and will seriously hurt my computers sound level. So, after looking around I thought, maybe I can buy something passive instead and replace it. Except everyone says when you do this you get a big hit in temperature increase on that chip and especially since the DFI's chipset cooler is right under the video card (going to be getting an X800XL), with an ATI silencer.

Everyone says replacing with passive will/can reduce life of your motherboard and you will see around a 10 C increase in temperatures on an already hot chip. My first thought was I buy some sort of passive cooler and attach a fan using some metal wires so it won't be touching the heatsink, but blowing on it. Well the problem with this is: I don't know too many heatsinks you can buy that will allow the video card to go in the 16x slot.

Then I swear, I saw that Gigabyte is going to release or alreayd has, a motherboard with heatpipes, and immediately that jumped out at me, because I was brain storming if I could some how use heat pipes on the motherboard chipset. I can't seem to find the link to where I heard about the Gigabyte board, but I also don't know how well it will overclock?

I'm going to be purchasing a 3200+ Venice in a month and need a motherboard that can fit an XP-120. I would like to be able to hit 2.6 Ghz and DFI seems to be the board to do it, although this noise has gotten me worried since many people say its LOUD!

If these boards arent it, what do others suggest? I also though maybe I should wait and see what ATI introduces as far as SLI and see what motherboards come out in that aspect.

Thoughts?

I use a 90mm fan (1600rpm) to blow on the chipset area of my Ultra-D. The idle temp went from 51C to 45C by doing so and that is with a Silencer 5.2 installed over the top of it. That is also with a chipset fan speed of only 3400rpm (inaudible). I use Speedfan 4.23 to control the chipset fan and have it set to automatically ramp up to 100% when the temp hits 52C. It rarely ever ramps up and runs quiet 99% of the time in 75F ambient room temp. I plan to apply AS5 to the chipset next time I have the board out of the case. The general consnsus is that 60C or lower is an A-ok operating temp for the chipset. Silence is indeed golden :)

Stokes,

Do you have an Ultra-D ? I have 2 DFI systems and the fans are not loud. The loudest thing in my pc is the Video card..

The fans on the Asus NF4 mobo's are loud. Maybe you got the two confused..

For me it dont matter how loud or noisy the fan is, it will eventually get clogged with dust and start buzzing and vibrating around.

i was allways wondering why the Nvidia chipsets are so much hotter then the VIA chipsets for example. Cant be the SLI ability, since the older chipsets were getting hot as hell too.
Does the usual suspect the Zalman NB47 fit without handicaping the graphicscard? Or does it have to be a flat and wide passive cooler? cuz id suggest to use muckers (does that rhyme on anything special, mucker?) way and go a step further and replace the fan with a Zalamn or whatever fits. All u need then to keep the chipset alive is a good Case Co0ling. for instance there are pci-slot coolers, u plug it into the pci slot and can turn and move the cooler inside ur case. dont have a picture right now, but they not hard to find i guess.
The best way is shown with ur pictures, too bad its an Intel Board, and Abit has not a big range of boards, hope they going to sell these boards soon, they need to cuz Abit is damn broke, which seems to have encouraged there creativity, finally.
Back to topic, i just got an idea: ermm build ur own heatpipe. Ya, i mean it. No, i dont, but ive seen people who did. They used stuff like PhasePlanes and even huge heatpipes to cool a highend pc complettely passiv. Sound like some hammering and screwdriving and maybe worse but its possible. here some links for ur insprition:

My chipset fan is really loud too, though I have an SLI-DR. I unplugged it from the mobo and put it on a PSU connector. It solved all my troubles for whatever reason and is now almost silent.

he's what you guys can do

Go to bios under pc health

Set chipset fan shutoff to 30
Set chipset fan max to 80

now it runs about 3600 and keeps the chipset at 57-58

If that isn't cool enough for DFI they should've put the chipset somewhere they could mount a decent heatsink. I do believe it is well within spec though.

heatsinks that are outfited with a fan usually do not have enough surface to radiate the heat. It relies on the fan to dissapate most of it. Lowering the voltage is a good idea, most modem solid PSU will have a 5v connector, but not ideal. Another idea is get the gigabyte one with passive HS and put a 40mm on it. Its not too tall to get in the way of the grpahics card and wide enough so the fan can be mounted to the side.

i think people are getting this confused with asus as mentioned. the stock cooler is fine if you have any common sense. if you want to chase some heat pipes down or throw on passive cooling thats fine. but the fan is loud at full speed only. what fan wouldn't be at 7000 rpm?

my suggestion is to apply as5 as the first thing you do. don't bother putting it in the case, just apply the as5 and use the same hsf. i run mine at 2000 rpm and its inaudible up to 3500-4000 or so. my chipset idles at 40 and loads at 45c. according to dfi tech the chipset is fine up to 60c where you should start worrying. like mucker said, you can control the speed very easily through speedfan or ite smart guardian you'll get on your driver cd.

the most important thing is decent airflow in the case. i have a vantec iceberg copper hanging around for a few months i was thinking of throwing in but i can't see the point. i also got a zalman fan on a bracket that i'll probably end up putting over the dimm slots instead.
