Crossfire 6950 temps

jack888

Recently installed crossfire 6950, graphics are amazing on 2560 x 1440 screen.

But I am noticing one of the cards is getting for hot. Around 75 - 82 with the fans going as high as 78 percent. Is this normal.
The other card is always around 15 - 20 degrees lower.

CPU stays around 50 degrees.

Fairly normal for the inner card to be substantially hotter that the outside one as the airflow is usually disrupted by the other card, although the tempratures are comfortable in the safe zone for a GPU I imagine the fans is a little loud.

You could try extra case fans to increase airflow which might help a little, but the solution most likely to work best is a third party cooler on the inner card if you have enough room to fit a decent one.

I have already installed two extra fans. How do I figure out which one is hot?, not sure how I can distinguish between the two, they are just labelled gpu1 and gpu2 on my tracking software.

Case is starting to get a bit crowded, these cards are big!!, dont think I could fit in much more.

With 99.99% certainly it will be the one whose fan is facing the back of the other card, they are probably labeled GPU1 in PCIe slot 1 and GPU2 in PCIe slot 2 but that doesn't always hold true for some programs.

How much of a gap is between the two cards?

As big a gap as I can have in this case.

I think it may be the card on the top that getting hot, so not the one with the back facing the other.....

The reason is, I had a wireless card blocking the fans of this one and when I removed, temps went down on it, but it was the one with high temps.

Oh so there is a decent gap between the two cards? (I had a pictured in my head of them much closer together like this.)

No theres a much bigger gap than this, here is a pic of it before I put in second card and extra fans.
