Zalman was not the only one who enhanced the already existing successful solution. The Big Water cooling system from Thermaltake has also undergone some modifications. The new revision, BigWater 735, acquired bigger sturdier tubes and a more powerful pump than the predecessor. In addition, the BigWater 745 model now has the total of three radiators: one inside the system and two external ones:
However, Thermaltake assured me that they have been long working on a specially designed system case that will be able to accommodate all three radiators one day. So, I believe the next big show, CeBIT, should reveal more details about it.
But truly one of the most impressive cooling solutions this time was the OCZ Cryo-Z Phase Change cooling system:
This is an external unit accommodated inside a small form-factor aluminum case with an elastic hose pressed with the copper base against the processor. It requires some insulation, which is hand-made at this point (you may notice that there are hand-cut gaps in the insulator around the electronic components on the mainboard). Inside this case there is also an industrial compressor that allows achieving much higher cooling efficiency than any liquid cooling system out there would guarantee.
As you may see, the CPU temperature is reported to be as low as -25o C. And the Athlon 64 FX-57 featuring the nominal core frequency of 2.8GHz is running at 3.3GHz.
This system is going to be very affordable, it is speculated to be prices at around $300. More details will surely follow, so stay tuned. :)
