Performance

Getting a temperature from the processor was a no-brainer, using the same probe I used for the heatsink. But, what I also needed, was a measure of the water temperature to get an idea of how efficient the cooler was being. So, I took another probe and poked it through the water top up point until it was in the water of the block.This is by no means perfect as it will most likely be taking the water temperature of the water after being heated up, rather than before it enters the block, but it gives us a better idea.

We overclocked the machine using the same settings as before (2319mhz) so we had a direct comparison to the AMD stock cooler.

Using Toast, it stabilised at 54.2c. The air intake was 24c and according to our probe, the water temperature was 38.9. At first, I thought the high water temperature was because it was measuring the water after it was heated, but upon feeling the tubes, it was obvious to me that was the water was running close to that temperature. This made me wonder how efficient the radiator was.

But, despite this, the cooler has managed around 15c above water temperature. Considering the estimated heat dissipation of around 70w, that gives us a C/W of around 0.20 which is excellent for such a small device. Also, with the stock AMD cooler, considering the air intake will usually be more like 40c than 24c and therefore around 84c, in most peoples cases, there will more than likely be at least a 30c reduction in temperature.

Globalwin have impressed us with the way they have corrected all the faults that reviewers have picked up, before it was launched to the public. We complained about our first model being noisy, only to find out they had released a new revision of the pump because of similar complaints. They sent us this version and it is incredibly quiet. All I can hear is the water moving inside the block, like some sort of silent stream (couldn't help myself, sorry).

I took two sounds clips using my digital camera. My camera tends to pick up quite a bit of background noise generally and is far too sensitive, so doesn't do the system justice. This one is with the fan and pump on, right next to each other, taken from around 12" away. This one is just the pump, also taken at 12".

Conclusion

At last, Globalwin have done it. £75 will get you everything you need for a good performing watercooling system with no hassle which is safe, quiet and reliable. Not only this, but the manual is well written. Perfect for anyone. Highly recommended.
