95 degrees is *very* hot, too hot to function properly for an extended period of time, the blackouts you had was the video card reseting itself, if it dosen't come back now it means it can't reset itself back to normal state anymore, only reboots would fix it (for a short while anyways) Also the weird graphic glitches you had are definite hallmark of an overheated card.
Clean your fans (especially if you smoke), make sure airflow is ok in your computer, add more if you can.
So I cleaned my front fans. The filters on them were completely covered in dust. I haven't played too much, but on Skyrim, it only goes around mid-high 60s now, but it will still freeze, no black screen. As for Starcraft, it hasn't done a black screen since, but there's still some small graphical errors in the terrain sometimes. Seems more rare and smaller. '
So do you think I did permanent damage to my GPUs or anything?
It's very possible the GPU was damaged yes, the blackout reset are a "safety valve" but running them continously in a overheated state might fry some chips.at 60-70 you should normally be just fine.
Since you have crossfired cards, might i suggest trying them in single card ? odds are it's only one of the 2 cards that's fried, you could run off the other (losing Crossfire but it'd work)
Also, you cleaned the case fans but does your video cards have fans or just a heatsink ? you definitely want to clean them up too.
I just tested on Skyrim again for about an hour. The main one goes around 80, high 70s. The second around 60. The problem still showed up in Starcraft when I first played after Skyrim on single card, as crossfire was not supported. The crashing occurred in Skyrim and Starcraft then as well.
The cards are the kind of cheapy ones, no fancy case, but they each have a small fan. I didn't put this computer together, and I'm still not sure about all of it, but the cards are pretty close in the computer, maybe a centimeter between the fan and the other GPU, could that be a problem?
No it shouldn't be, Crossfire and SLI are meant to be close together, it would be a problem though if the GPU fans are dirty, since there's really not a big margin (dirty fan+1/2cm airspace=bad)
Also, possibly stupid question, is there a way to choose which graphics card to use when in single card, or tell crossfire which one to use primarily, or balance out the work more equally? In Skyrim, one card will be 100% activity, the other will be 80 or something and like 20 degrees less and in Starcraft, one will be 100% and the other will do nothing.
As far as i know, no.Crossfire/SLI does the calculations about which card does what by itself, it's never an even burden, there's always gonna be a primary and a secondary card.If say there's 10 figures to draw and 3 backgrounds crossfire will give the main workload (10 figures)to the primary card and give
workload that would have to wait (backgrounds)to the secondary card.It cuts down on graphical lag but it dosen't really unburden the primary card, it just helps clear the queue faster.
There would be an easy way to test if your cards are fried or just hot, open up your computer case and aim a desk fan straight into it, it's obviously gonna make a ruckus so it's not for long term but it'll lower the general temperature by a good 10-15 degrees.If you still have the graphical artefacts (color glitches etc) it means a component is fried, if it works fine with a desk fan blowing in your computer, you need to improve airflow.
Edit: note that in single card mode, it's only the primary that works, and the primary has the greatest chance of being the one overheated since it always runs hotter than the secondary.If you still have glitches with a desk fan, i'd suggest removing the crossfire setup altogether and just put your secondary card in by itself.
