Testing and Results

As I said, the screen shots would turn up to say I was running a GTS 250, and by swapping the BIOS, essentially I am. As you can see, the BIOS swap was to increase the card to a safe overclock for F@H. Since the BIOS is set to run with a pretty good overclock, I'm just running the tests with these clock settings. There isn't going to be a typical idle and load test, just the one run, which I will consider an overclocked state for the sake of typing.

The test I chose to torture the coolers was Ozone3D's Furmark. Testing was run in stability mode for twenty minutes, both with the stock cooler and the ZEROtherm. At this point I just click Go and wait for the results.

Here is the stock cooler controlled by the BIOS. I had what I thought was a warm card by these readings, idling at 64° and loading fully after twenty minutes at a maximum of 82°. Rather warm in my opinion, no matter what cooler we are discussing.

Just for the sake of argument, I set the fan on the CoolMaxx 2000 as low as it goes, so I was only sending five volts to the fan. Even so, I was surprised to see that the results were near stock cooling performance levels at load, but I got over ten degrees at idle drop in temperature. This had me excited to see what the CoolMaxx can do at full go.

The last run I did was with the fan controller turned to the highest it will allow, about eleven volts. Not only did I drop yet another four degrees at idle, the CoolMaxx 2000 bests the stock cooler by just under a full twenty degrees. What an improvement over my stock cooler!

Just to keep things simple for comparison, this chart is for easy reference head to head, stock versus the CoolMaxx, but also both fan settings. I couldn't really include a sound chart. With the system I was testing on was built "open air" and the CPU and PSU fans were both louder than the ZEROtherm CoolMaxx 2000 at its highest setting. In this instance it wouldn't be fair to record and report the sound levels of everything but the ZEROtherm.
