CF Reference 6970 "next to each other" sounds like a bad idea!?

post #1 of 15
Thread Starter 
Hello guys!

Listen, I'm thinking about getting another 6970 to go CF, but it happens that I can't use PCI-E 1 & 3 because my case isn't big enough, and I just don't like to get another one at the moment, so, it looks like I'll have to use PCI-E 1 & 2. So here comes the question, do you think the temp of the card on top could get excessively hot?? I'm talking of course, about 2 reference cards. I wouldn't like to watercool the graphics cards either.

Any of you are running a similar setup!?

BTW, right now my temps are 38 idle, 63 load.


Thanx in advance for your support! Grettings!!!

I had to run my 2 5870's in #1 and #2 for a little while and didnt really notice a difference in temps.

Id just keep an eye on it at first but your be ok.

The top card will always run about 8-10c warmer anyways.

I have 2 6970s together at 55% fan speed, IT SOUND LIKE A HAIR DRYER!!! I Do not recommend it if you are sensitive to noise, or don't plan on getting a waterblock or an after market cooler. Any lower fan percentage the temps on the hottest card (GPU1) will reach high 90C.

It ain't that bad, 2 cards @ 85% fan aren't much different/louder than 1 card at 85%. You would see an increase in temps but not too much. I ran 6970s CF before.

they will work, if the temps really bother you you can crank the fan up on the top card....or you could just leave them on auto and if anything does go wrong while under warranty then rma it.

GPU's are pretty resilient and if they fail from temps too high in use as intended then they should be repaired or replaced by the manufacturer

Why not use a custom fan profile in MSI Afterburner?

As others have said, it'll be loud but manageable.

Tip: Plug your hdmi/dp/dvi cable into the bottom card so that it is the main workhorse. Should help your temps by a few degrees.

I appreciate the fast answers guys! Right now at 63°C my fans are at 60% (more or less). I think fans at 85% of speed would be very annoying since I have my rig very very close to me in my desk. I don't think the bottom card will suffer, but the one at the top... fortunately MSI offers 3 years waranty, maybe I should give a try, worst case scenario, I could get another case...

would you mind telling me what temps are you getting in both cards? idle and load please!!?

If the temps get high (thus causing the fans to get loud), you can wedge a piece of cardboard or the like in between the cards to allow for air flow to the top card. Also, I strongly recommend a side case fan blowing towards the cards. Good luck.
