Well if your load temp is 90c,then its normal;therefore, the freezes may not have been caused by overheating.
1_Yes it will help
2_You have to have overall good cooling solution in your case for a CF rig.But yes,an additional fan will help
If you're using 2 x 4890's then , usually a mobo has pcie placements in such a way that there is a step one ration to the x's meaning,
1st slot 16x
2nd slot 16x
3rd slot 16 x
This is when using One Card
If you have 2 cards
1st slot 16x
2nd slot 8x
3rd slot 16x
Populating the 1st and the 3rd slot if what is usually done, if you populate the 1st and second slot they'll both work a 8x
and 3rd case scenario is with 3 cards
1st slot 8x
2nd slot 8x
3rd slot 8x
Although these vary with the model and manufacturer but it still has a chance,
why don't you just populate the first and third slot and check the temps again.
ATX77 RAIDMAX. It is small but has plenty of fans in. I dont think it is the cooling anymore. I have opened the one side of the case and put a monster big fan next to it and it runs fast and the cards are a lot cooler. In anycase, games like just cause 2, Left4dead2 and ARMA 2 run nonstop on these cards.....
No other cards in my system. Using onboard sound etc. It feels as if some setting somewhere is wrong. Should I have changed anything in the Bios when I enabled crossfire?
This is likely a software/driver issue. Try reinstalling the drivers, 10.4 is the one I found most stable for 5850 CF but other packages may work better for you. Also, if this doesn't work you may need to try reinstalling the OS.
Not always, if they crash then it could be a heat up problem too.
The driver software problem usually gives and error message when the game crashes or a program performs an "Illegal Function" as windows calls it....
When I upgraded from 10.4 drivers to 10.8 BFBC2 would crash back to desktop without any error or notice, it just acted as if I closed the program. When I reverted back to 10.4 this stopped happening. You could look up the system logs to determine if software is the case, you will usually get a bit more info there but not always. Hardware could be the issue, the cards could be getting old or have overheated causing damage, but if some games work then it is more likely not a damaged card, more likely software.
Or maybe it is just some games...................... As I mentioned, ARMA 2 works fine and that game absolutely destroyes fast machines in general. Maybe it could also be that it is becoming summer now and where temps were 15 degrees 1 month back, it is now 35 degrees.............
Yes, this could be an issue if your reaching your maximum temperatures. Try running MSI afterburner and look into the temperatures vs fan speed. If your not reaching 100% fan speed you are likely not overheating. Try manually cranking the fan speed to 100% and see if you can run games again.
I am at work now so will only respond tomorrow again. Yes, I am from the southern hemisphere...

Hi i have the same problem but i switched off any overclocking in BIOS and on Graphics Cards.
And still have this problem right now is showing 75 degrees with no 3d animation on and fan speed is 35%
but why GPU clock showing 240mhz - this is the question for 1 million points.
cpu - intel i5 2.67ghz
motherboard - p7p55d asus
graphic card - 2 x ati radeon hd 4980
ram - 12gb ddr3 1333mhz xms corrsair
power supply - thermaltake 550w
