Yes, that is one weak solution. You can jumper the 2nd PCIe slot from
2x to 8x (iirc) and use it. Now you cannot run SLI. That is nonsense.

I do not believe in crippling a high-end machine with weak solutions.

I will find a passive cooling solution for this eventually, even if I have
to make my own.

Help me out here. Do you mean setting the board jumpers for sli & then just using 1 card in second slot or some other means? If it's set to sli are 2 cards not mandentory? I was thinking about using the second slot thinking it was 8x but I guess that's only when sli is enabled, otherwise it's just 2x. Is that correct?

Yes, if you move the jumpers, the bottom slot becomes 8x's and you can use that slot only (or both). Reported performance is a 1-2% 3DMark loss (if that). If you can't get your temps under control it's worth it.

DO CONSIDER the evercool and an aftermarket cooler for your GPU like the NV silencers that vent the heat out the back of the computer instead of inside the case, or worse yet, directly on the chipset.

That is a funny statement as one of the selling points of the zalman VF700 is that the air the fan pushes moves over the chipset helping to cool it. With the silencer you are stuck using the air in the case (which should be cool if you have good airflow) but with the VF700 the fan pushes air through the heatsink and to the chipset cooler, this works well if you decide to get a passive NB cooler.

This is the same thing that happens when you use a thermalright CPU cooler. The overhang of the fan helps cool the RAM and other components on the board.

Thanx 4 the input VStrom. I'm wondering why he said you couldn't run sli. I do have a NV5, I'm wanting to try an exhaust cooler on the chipset.

 

[vanvock]

But that air that it's moving through the system is is heated, right?

Depends on your board design and where your components lie. I can tell you my chipset temps dropped and my case temps dropped as well simply from installing the NV silencer. I have a DFI Lanparty board.

I believe (check on DFI-Street to be sure) that the Lanparty boards have the SLI slots too close together to fit 2 cards with the NV silencers. If you aren't going SLI, no worries. Apparently the DFI Expert board doesn't have this issue.

 

[vanvock]

OK thanx again. I thought he was refering to some other limitation. No sli for me yet, unless I got another 6800gt which doesn't make sense to do at this stage of the game.

I do not believe you fully understand what is being discussed.

You are caught up on the ability to use the second PCIe with a single
card without realizing just why the described scenario abandons the first.

The reason is simply that the NB cooler would block use of the first PCIe.

Of course, there are other options, this was just one scenario, and not
a desirable one since it does not allow you to use SLI. Understand?

So, for now, people are using Evercool, not a passive cooling solution
like the Zalman as they block the first PCIe so you cannot run SLI.

 

[VStrom]

LOL, now I'm confused! Let me summarize. The evercool VC-RE can be mounted on the chipset without any adverse consequences to installing any VGA cards in either (or both) PCIE slots. It's basically the same height as the stock DFI chipset fan.

If you want to run SLI, I don't believe it's possible if you have the NVsilencers mounted on your VGA cards. I'm not sure if this applies to all of the NV silencers but for the 7800 (NVS 5 rev 3) it is too big and overhangs the other PCIE slot.

 

[kaishaku72]

The inability to run SLI I was referring to was not related to VGA cooling.
It was related to using a passive NB cooler, such as the Zalman NB47J.

To use such a passive solution, you must give up your first PCIe slot.

You cannot run SLI in such a scenario, regardless of VGA cooling.

This thread was about NB cooling for while.

Yes, I got it. That's exactly what I intend. You are caught up on SLI while I'm working on a single card system. I don't intend to run SLI anytime soon. I'm just trying to figure out if it's worth setting up that way so that I am not limited on chipset cooling options. Understand?

To say I am caught up on the SLI is incorrect and feels rude.
I mentioned loss of SLI long ago as a logical consequence in
a thread previously non-specific with respect to SLI/non-SLI.

EDIT: Now that I see your "Understand?" in addition to the
"caught up on SLI" I know you were mocking me. As such,
let me simply state my intentions in being clear and concise
in reply to your confusion were entirely sincere. So, relax.

 

[vanvock]

I suppose we are both going on bad impressions. You're response felt condesending thus my "mockery" which was not intended to be rude. My apologies to the OP for injecting any confusion.

i found using the stock cooler with as5 and a silencer on my gtx to be a perfect solution. chipset idles ~40c, load ~45c @ 2500rpm. i can't hear it at that speed in either my CM praetorian or my antec slk3000.

i will say that once i got the gtx, the vf700 went onto a shelf for the silencer. the gtx sent my chipset temps rocketing and even moving the card to the second pci-e slot didn't help much.

so enter the silencer. back into slot one and back to normal temps.

btw, the performance loss in using slot 2, say its 1-2% (which is what i saw) is never going to be noticeable. so trying to work around having to use the second slot is just making things difficult on yourself.

Thats where the issue comes in. Supposedly there is some performance loss when using the lower PCIe slot as it only runs at 8x. It may only be a few % but thats a few % that I don't want to lose.

-spike

There is no loss worth to mention. I tested it in both slots and if you really want to find a difference, it will be around 1% at the very most. 8x is still around 2GB/s bandwith.. more than enough.

Thats humbug, you dont want to feed the NB fan with hot air from the vid card. It was one of the 2 reasons I went for a NV Silencer, because the stock cooler on the 7800 line feeds hot air directly into the NB HSF. It wont be nearly as bad with a Zalman compared to the stock cooler on the vid card, but it also wont be as good as exhausting all heat from the video card instead. There are other ways to provide the NB HSF with air, especially on the DFI Lanparty boards. Like placing a 80mm fan over the MOSFET and NB area. Kill 2 birds with one stone.
