oops, seems like sig was empty. rectified

Looking at my photos, it is clear more of the fins would have be trimmed a bit where they would contact the bottom card. I doubt it would have a big effect on nF4 cooling.

BTW, the NB47J is not symmetric. One side has shorter fins on it than the other side. If you put the longer side towards the top of the board (back of the top video card) you might not need as much trimming for the bottom card.

I am a bit concerned with a DFI SLI setup how close the top VF700 is to the bottom card. That would seem to impede airflow. The Asus A8N-SLI has better card spacing.

I was wondering if even more bending would do the trick, instead of cutting the already tormented fins

Maybe bend them halfway to slip by the bottom card..

I didn't know that, I sure will try it that way.

Yes, I know the issue. I wanted less noise and better cooling than the stock solution in the first place. I first had to return a couple of nv5 silencers that had NO chance of fitting together (silly me, I measured wrong

) but then the zalmans faired quite well given the stranded space. I wish I had the Asus spacing with the DFI OC performances, but I guess you can't have them all.

Thanks for the input

Ahh, so the NV5 Silencers can't fit in SLI?? Wow, that's a great tip, I was about to buy the NV5. I guess it's the VF700 for me then as I'm planning to go SLI in the future. Thanks

Ok, I have mangled my NB47J just so that I can move my video card from the bottom slot to the top slot and run it at 16x.

But now my temperatures have risen sharply - 46 degrees idle, 49 load. It used to be 40 idle 44 load... And performance increase is negligable.

Oh well, guess as long as it stays below 55 I should be fine?

I'm probably not as picky about silence as most here (maybe my ears aren't as good and/or my desk shields the sound), but here's what I have:

Chaintech Dragon Tower Case
DFI NF4 MB
Winchester 3000+
XP-90 with a Panaflo 92mm
2 80mm Panaflos at 7v in the front
2 misc fans in the back running around 1000rpm each
ATI X800XL

Like many others, my chipset ran hot, esp when gaming (up to 54c)
Now I never let it get to 8000rpm, but above 4k, it got annoying.

My other problem was the X800 fan, which was worse than the Chipset (mostly because I didn't let the chipset go over 3900 RPM).

After reading up on SPCR, I decided to pick up a VF-700 and the Blue NB Heat Sink.

After putting on the 700, my card now tops out at 60c (generally 56c) when gaming. That compares to north of 70C with the stock solution.

But the other benefit is that my Chipset now idles at 43c and never goes above 48c.

As a result, I'm not convinced that I'll gain much by using the Zalman HS on the NB.

So before you swap out the NB fan, it might be worth figuring out how fast it can spin before it's too loud. I think you can probably get away with as low as 2900rpm (less if you're not gaming/OCing).

That's my 2 cents.

If you want to use the upper pcie slot with a longer/modern video card. Why not get an Evercool VC-RE cooler? It runs very quiet, pushes more air than the stock fan, all copper. It's a drop in replacement, no need for bending, cutting, etc.

I have Speedfan controlling the NB fan according to CPU temp (NB doesn't seem to get hot unless CPU is stressed), and it's spinning at about 1800rpm when idle. With about 21C ambient temp the NB temp is about 47-48C, and it's virtually inaudible over the muted whoosh of two Papst 120mm fans at about 750rpm in the Antec P180.

When CPU is heavily stressed during gaming the NB fan speeds up to 4000rpm, and NB temps go down to 43-45C. Yes, 4000rpm makes noise, but (un-) fortunately it's inaudible over the X1800XT in action. Sadly the X1800XT is also capable to cover the noise of a vacuum cleaner

Whole thread about it here.
I've emailed the manufacturer and reviewer, so we'll see what happens...

Jeez, what a long link!

It translates better if you use Traditional Chinese translation and not Simplified Chinese.
