Crossfire Bottom Card 70c Top 90c Temps

post #1 of 18
Thread Starter 
I have a Antec 900 series 2 with crossfire 4890s top card is obviously going to be hotter but its running 90 degrees celsius. at the end of Heaven Benchmark v2.1 getting a score of 1080 and average of 45 fps. bottom card is getting 71c temps at the end. is this normal? No overclock! is it safe to overclock crossfire?

Temps are believable. Can you add a fan inside the case to circulate air around the cards?

Overclocked cards in crossfire? Why not?

My case is antic 900 series 2. Top xfx 4890 get 90c on load and bottom gets 71c on load at end of heaven benchmark. Are these defective temps or are they ideal. I need to get a side fan mounted on side I'm sure. Both cards are sandwich next to each other.

That series card runs very hot to begin with, and your case isnt the best for temps/internal spacing. Are the cards right on top of each other? Like this?

Seems like the BIG fan on topp is SUCKING in air.. and all the hot air is being exhausted through the back... I would want the opposite..??? big fan at the top pulling all the Heat that is rising out of the case...

Unless you reversed the fan its pulling air. I have that case. One thing you can try is what is suggested and place a side fan. Another is to try and place the GPUs further apart if your motherboard will allow it.

Check that your cabling isn't restricting airflow. Try and pin as much to the bottom of the case as possible and reroute it underneath the board as much as possible, and try and push as much as you can out of the way of the fans. Some cable ties will come in handy.

Move the fans so that one is blowing between your PSU and second GPU. This can get hot and the PSU can draw cool air away from the second GPU.

Check your case fan speeds, they're set to low as default and I found that to not be enough when running Crossfire.

The rear and top fan should be outtake by default. The front fans should be intake. You can test this by laying a piece of paper across the fan grill and see if it sticks to it or blows off it.

I also have a 120mm side fan blowing onto the GPUs.

Here's some pics:
