I'm pretty new to this whole deal. My friend got my started on it today. Essentially my issue is that I'm running 2 4890's and they over heat after running GUIMiner for about 20 minutes. I've ramped up the fan speed to no avail. They still over heat and the system crashes. I'm assuming this isn't normal seeing as how some people run systems 24/7 and successfully make a little money. I've never had any issues with these cards over heating what so ever in any other circumstances. I am running them in CrossFire, but it seems to be the only way to get it to use both cards. If it isn't running in CrossFire, then it will only work at the speed of having just one card running. Even with just running on one card, it still over heats the card. Any suggestions? I'd really like this deal to pay for a new set of video cards. lol

Cards need a lot of airflow. If they are spaced at least 1 slot apart then you need more ventilation in your case, try leaving the case open for starters. If they are right next to each other, try folding some paper and wedging it between the cards to open up more space for airflow.

Thanks for the suggestions. There's a little bit of room between the cards, but they're still a little close for comfort. I did run out of funds on my computer build about 85% of the way through. I got all the major hardware and everything to get it going. At the time I built it, it was quite the power house. A lot of the little details were left out though and frankly other projects came up and things got forgotten. I didn't put a fan on the side of the case, which is right over the cards. However there is a hole there that the fans on the cards themselves can pull air through. I sat down last night before I went to bed and I couldn't remember the last time I cleaned the system out. That in itself is bad as we all know heat kills everything and dust only helps heat. I don't have my air compressor up and running, so I'm going to see if I have a can of air floating around to clean the whole system. I am sort of leery about leaving the side off my case because my son will be all over my computer and more than likely so will the dog. I've got a few other tricks up my sleeve. I'll try a few things out and report back. Hopefully my problems will be solved and my computer will start earning its keep.
