Sapphire Radeon HD 5870 1GB in CrossFire - Temperature and Sound Tests

The only thing better than one HD 5870 is two at the moment, so we slide two into our X58 testbed and see how they play together.

Temperature Tests

 

 

With the TES 1326 Infrared Thermometer literally in hand we found ourselves getting real-world temperatures from the products we test at load (3D clock speeds).

 

There are two places we pull temperature from - the back of the card directly behind the core and if the card is dual slot and has an exhaust point we also pull a temperate from there, as seen in the picture.

It was interesting to find that the second HD 5870 really didn't carry with it any more heat. It seems that the extra holes at the back of the card help draw cool air in.

 


Sound Tests

 

 

Pulling out the TES 1350A Sound Level Meter we find ourselves quickly yelling into the top of it to see how loud we can be.

 

After five minutes of that we get a bit more serious and place the device two CM away from the fan on the card to find the maximum noise level of the card when idle (2D mode) and in load (3D mode).

Not really too much of a surprise that the noise levels from the cards were similar.
