GIGABYTE 9800 GT Zalman Edition - Temperature and Sound Tests

We pit the newly released 9800 GT from GIGABYTE against the new mid-range king; the HD 4850. How will they fair?

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.

The 9800 GT isn't plagued with the same heat issues that are present on the HD 4850 with its stock cooling solution.

 

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).

The Zalman noise levels are pretty standard with load showing no real difference. At idle we're sitting a little louder compared to the stock HD 4850 cooler.
