Trifire 6970's need crazy cooling solution... Have Ideas?

post #1 of 55
Thread Starter 

This is my setup


Since those cards are stacked, the one in the center gets insanely hotter than the others.Im thinking closing off all the airflow in the case so it is FORCED to be pushed through the cards and out the exhaust. I have tried putting a slice of cardboard inbetween, but there is so little give I can only stick one in 1 place, and it offers no temperature change...

Do you guys have any ideas?

Some good fans on the side would do. I'm aware the HAF X comes with a single 110 CFM 200mm fan on the side, however I'm not sure if you can install four 120mm fans there like you can on the 932 (without modding it). If you can, four Deltas will run you about $100 and will more than quadruple your airflow.

It won't cost $1000 to get three blocks, pump, reservoir, fittings, radiator, tubing and fans, etc. But if you need a solution now, could you remove the middle card till you have a solid answer? Or move the bottom card to the last slot, or will that mess with speeds? I don't know how the CHV works in the PCI-e department

Or you could do what everybody else is suggesting, I have a 120mm resting on my PSU blowing directly on my card, if you position it near the back it could squeeze some air between where the fans are.

So spending over $900 on GPUs is cost-effective, but a few $85 waterblocks is ridiculous?

Have you tried taking the backplates off? Additional clearance for fans or more "cardboard". Tried temporarily rotating the case so the GPU's exhaust is aiming towards the ceiling?

Some variation of this is your best bet. Also, you should be able to slide in place more than just one sliver of cardboard. Look for a thinner stiffer piece. You could also look at a PCI-E slot cooler or whatever they are called. I think Antec makes one. Placing an 120mm fan or even an 80mm fan right in front of, or underneath the cards should provide a little relief.

That's not really a fair statement. The cheapest blocks maybe that price point sure, but others are near $115 a piece. Then you have to factor in a pump, radiator, fittings, hose, etc. More like $600 minimum.

water, trust me

I had two 140mm fans pointed at the three when they ran the stock cooler and it barely helped. On water they top ~40c.

Since these cards are double space with their coolers on, they cover all the slots in trifire.

As far as airflow goes, I guess noone watched the vid lol, I have 2 floor fans ducktaped inline blowing 60 degree AC air into the side of the case.
