Remember how I used to always talk about how my GPU1 was always a lot hotter than GPU2? I switched my GPU positions (GPU2 > GPU1) and found that one of my GPU2 was higher in temps (remember , I swapped this from top to bottom). I knew this wasn't right because GPU1 is supposed to be hotter than GPU2 in SLI, yet here i swapped my cards and GPU2 is still hotter.
So I took my card out and inspected further, and I may have gotten a used card from newegg. Thanks newegg (I bought this on week 1 by the way, W T H??). There are fingerprints where there should be none (on the PCB!) and such, apparently someone before me removed the shroud as well. I'm not HAPPY abou this, but i'm not complaining *that much*, because this is my golden chip that does 1400 .Newegg gave me a 50$ coupon so whatever. So anyway I remove the shroud and reapply PK1 TIM and reseat the shroud and my temps literally improved by 10C. I am just floored by this because both of my lightnings run within 1C of each other in SLI now.
I just did a 1402mhz run in SLI and before that would make my GPU1 go up near 80C. Now both GPUs are around 70C at that speed! Better yet, my GPU1 doesn't get far hotter than GPU2 in SLI like it did previously.
And GRR at newegg for selling used cards. I *may* try that hexedit thing now, i'm feeling brave today. Or maybe i'll wait for water blocks Edited by xoleras - 7/31/12 at 7:01pm
