Overclocking the Sapphire HD 5670 1GB Video Card - Temperature and Sound Tests

We've heard whispers that the HD 5670 has a bit of overclocking headroom. Today we take the time to find out for ourselves.

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.

While we might be pushing extra MHz out of the core, the overall temperature of it hasn't changed much at all.

 


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).

Looking at the sound tests, there's also no change which is good news.
