Test Results

Here are the idle test results when compared to the stock 7900GTX cooler:

idle temps nexxxos

As you can see the idle temperature does not tend to go down much at all from the stock cooler. This is perhaps due to the stock cooler being able to cope with the idle temperatures pretty easily. A 4°C drop isn't too bad though.

The load results:

nexxxos load temps

Here is where the NexXxoS really shows us what it can do. The temperatures at load only went up 8°C over idle. This is a drop of 16°C over the stock cooling solution.


I did a quick test of the overclocking increase this reduction in temperature would give. I was able to overclock the card to 717/870. This is an increase on the stock cooler of 7MHz Core and 5MHz memory. This gives an indication of what could be achieved for the serious overclocker - if voltages were increased in the cards BIOS you could get some excellent speeds.

Great review mate, I sadly can think of many improvments they could make to the design.Quote

Mr. Smith
Sound methodology and a balanced conclusion.

I'd take the EK over the alpha due to ability to change barb direction... That and it performs better lolQuote

Thanks guys for the feedback, it's very much appreciated as it allows me to refine the process. Is there anything else that you would like to see done in future reviews that I haven't included?Quote
