About two months later I was contacted by Lesley Lazerus of TherMagic and invited to test the TherMagic CPU Cooling System in our own setup. A few days later FedEx delivered a package from EverGreen Technologies. The setup comes fully inclusive with the cooling unit and cold plate already assembled and supplied were mounting clips with thermal compound.  I removed the Volcano 7+ from my P4 MSI board and cleaned the CPU with some isopropyl alcohol. I had to remove one of my dual exhaust fans from the back of my PC to make room for the cooling unit. Most cases will only have one exhaust fan but don’t worry the cooling system as an intake fan and an exhaust fan, so you will not be loosing any airflow. As an added cooling bonus the heat generated from your CPU is carried way using the water cooling system and exited from the case never being given the chance to blow its heat into your case like a conventional Heatsink/Fan combos. After applying the supplied thermal compound to the heat spreader on the P4 I placed the copper cold plate on top of the CPU and attached the mounting clips, no tools required. The water-cooling housing is attached to back of the case where the exhaust fan used to be mounted using push rivets. I then attached the power connecter and was done; it was so effortless I felt kind of guilty. The system was powered on to get some temperature readings. On our 2 GHz system the average idle temp was 105 to 107 degrees Fahrenheit. Using Sandra http://www.3bsoftware.com/downloads/sandra.html we ran the CPU burn-in procedure to task the CPU. The average temperature during this max load was 122 to 125 degrees Fahrenheit. How well could we push this 2 GHz processor? After increasing the front-side bus to 120 MHz (480 Bus Speed) giving us 2.4 GHz of speed we ran our temperature program again. The idle and full load temperatures were 109 to 111 degrees Fahrenheit and 125 to 127 degrees Fahrenheit respectively. We pushed the system to its limits of 2.5 GHz and obtained a temp reading of 127 degrees Fahrenheit however the system was not stable; not because of heat but the lack of the boards’ ability to increase it’s voltage beyond 1.6 volts. I am confident that the cooling would have kept up if we could have supplied additional voltage. This will be re-visited in the future with a board that can supply more voltage.  The thing to remember here is that this system is not designed to take your CPU to sub zero temperatures but to provide a better cooling system that increases the life of your CPU and system components while lowering your overall system temperature. After the amazing ease of install and obvious ability to cool the system and exhaust heat from the inside of the case I can say that this set up is a definite winner. I have heard that they are also working of a more advanced “Gamer/Enthusiast” cooling system that will provide the extreme cooling many overclocking gamers and PC cooling enthusiasts may be looking for. I will be taking this system to GDFest 2003 www.GDFest.com this weekend to give it run for its money on cooling my system for a full day of gaming. I will post additional results of testing if necessary. More info at: http://www.thermagic.com/ Bill Landon Senior Editor |
