Voor sommige mensen is het koelste nog niet koud genoeg. Steve Foster (van HardOCP) was op zoek naar een koelsysteempje voor zijn dual. Wat hij zocht (koeling tot -50 en minder) kon hij nergens vinden (he, wat gek), dus zelf aan de slag.
The true test, a working computer. Everything was turned on and the power supply to the peltiers was set at 12v. Before I had the login screen for WinNT4.0 the processors had dropped to –4C. Within twenty minutes I was at –28C. This was getting exciting. I loaded 3D f/x and started rendering a 2min animation (1.23Gig file) which takes about 2hrs 3min. The system continued to drop until I had reached –43.1C (measured from the center of the thermal plate). Once I finished the rendering, after about 15 minutes the processors were at –58.3C and –59.7C. I set the power supply to 9.7V and maintain a temperature of –35C right now and will continue to test different voltages and check for condensation to be certain that everything is airtight. Next stage will be to cascade the peltiers to see if –80C can be achieved. This will get me real close to the ability to double the clock speed.
En nog niet tevreden zijn !!
Helaas nog geen benchmarks, maar een verdubbeling van de kloksnelheid klinkt goed !!
