yep, just make sure you have enough room inbetween the 2 cards.

As I have just discovered through my thorough searches.. 2x vf700 cu when using SLI isn't as good as the stock coolers even. And since I have an SLI-DR I can't use dual NV silencers. Currently I have EVGA SLI with 1 stock cooler and 1 ACs3 cooler. Which card would I be better putting closer to the cpu? and is it worth changing either of them to a secondcary cooler.. nvsilencer on the 2nd card or a vf 700???

Also, I just realised that I have my psu exhausting air into my case right at my video card (Antec p180 case and the psu blows air up!) Should I change this around so it blows air down?

Thanks!

in this case you should get more fans exhaust hot air out from your case.
vf700cu is better than stock cooler even in SLi situation but you need good ventilation.
and add some front fans that can get fresh cool airs for your SLi.

Zalman VF-900 is coming soon. It has heat pipes and is very low profile. Might be the solution to your problems.

well, from the photo, vf900 didn't improve thing that user requested in vf700.

vf900 still using external powers for fan and make cabling difficult.

and seems it still has no automatic fan speed adjustment.

If zalman created a video card cooling that can exhaust hot air out side the case, I would buy immediately.

I think EVGA lets you change the heatsink? they sell the ACS3 standalone kit!

Also, I'm worried about my cards burning up.. I believe I hit high 80s when gaming!

What kind of case do you have? Do you have an intake fan?

High 80's is completely within specs of the card, but it is a little warmer than I am used to.

I have an antec p180 and DFI SLI-DR board. I have major temp problems. My chipset gets up to 65c. (right under/between the 2 vid cards)


I have a nexus 120mm silent intake right now - but I'm upgrading to panaflo 120mm L1A. The top and rear outtake fans are antec tricools @ medium setting. I MAY decide to upgrade these to better fans.. but I'm not sure I want to have louder fans.

I also think I have my psu blowing hot air into the case (which I am gonna check - i'm not at the same place as my comp right now) in which case I'll be turning it upside down!

I really need a cooler solution because my parts just get far too hot.. poor wire management may be partly to blame but I just don't have anywhere to put the wires :(

specs are:
x2 4400+ @ 2.625 1.43v w/ xp-90 and 92mmL1A
2gb ocz ram (2x 1gb)
evga sli gtx 256
sb audigy 2 zs
dfi sli-dr
fortron 700w

and remember
exhaust is more important than intake.
make sure you have enough fans to exhaust hot air.

Any word on when this is actually going on sale anywhere?

Here are some HiRes images of the new VF900. Looks like it is thinner than the vf700. Hopefully it will perform better than the VF700 in SLI.

Well crap, just read that the VF900 was not due to be out till Q2 this year:

Zalman's booth had a few nice surprises in it this year. What caught my eye first was the new VF900 VGA cooler. The upgrade to the popular VF700 adds a heatpipe and a few more fins to improve its cooling abilities. Its expected to be released around Q2 with an unspecified retail price.

When I first got this case, I had the same problem with chipset temps getting too hot for my liking. I solved this by removing the middle HD rack, and installing a fan there. And also installing an slim 120mm fan in the lower HD chamber.

I already have a fan there and hd rack removed hehe.

I ended up replacing the stock HS fan with a Evercool VC-RE and with all fans on silent mode, I'm gettting 10c lower load temps on chipset, and 7c lower idle.

if I crank up the fans, it keeps muhc much cooler.
