Parallel config suddenly destroyed my Tri-SLI temps

post #1 of 4
Thread Starter 
A few days ago, I ran three 580s on XPSC blocks using Bitspower bridges in serial. For the ten minutes I ran Heaven benchmarks, the temps were beautifully in synch. I say 10 minutes because one of the blocks turned out to be cursed and shorted out my third card, and eventually a fourth.

Anyway, fast forward to today. Install new block on new card, replace a couple broken "high flow" Koolance QDCs with working "extreme flow" QDCs and the Bitspower bridges with Koolance Dual VID bridges.

That's all I changed. And yet, my temps have gone to utter **** on my middle card. 14C higher than the top card. So my temps are like this: 44c, 56c, 41c, running stock in Heaven.

Aaaand this problem (presumably) just crashed the benchmark.

Obviously it's not restriction, otherwise card 3 temps would be even worse. But obviously it IS restriction, otherwise my second video card wouldn't be getting starved of water and apparently bypassed. As you can see, that makes no ******* sense.



Why is everything with WC such a pain in the ass, sigh.

Going to try serial now just to make sure the second card didn't magically unseat itself on the block.

Its not uncommon. I had the same problem with my original 5970+ 2x5870 running in parallel with a single D5. You lack sufficient flow rate to evenly distribute the flow evenly. The flow will naturally follow the least route of resistance unless there is sufficient pressure and flow rate to evenly distribute it. I went to serial config and have never looked back.
