3D Spotlight : Hardware : The Card Cooler review

The Card Cooler review
Posted by Adam Klein on August 16, 1999 - Page 3/3

Heat Monitoring

A wonderful thing about motherboards being made today is their ability to monitor temperatures through diodes placed on the motherboard. With the Abit BX6 revision 2 I have, I can monitor the temperature anywhere within the system through the use of a probe that was Abit's remedy for the faulty CPU temperature monitoring diode. I placed the probe directly on the backside of the stock heatsink on my Creative Labs TNT2 Ultra.

Here are my heat monitoring results after 15 minutes of play in Quake 3 and various clock speeds.  The system was left to rest for 30 min between the tests.

170/207 with standard cooling – 123.4 degrees F

175/215 with the Card Cooler – 96.7 degrees F

As you can see here, the card cooler can help cool the card quite a bit, but it can also reduce the temperature of an already well-cooled CPU. The Global Win Heatsink/Fan does very good at heat dispersion, but with the Card Cooler helping to keep other components cool, the CPU stays cooler as well. The diode on the BX6 r2 is not in direct contact with any metal surface, but is placed very close to the Slot 1 interface.

These are the results of the on-board system monitoring diode present on the BX6 r2. They were recorded at the same time as those above.  

550MHz with standard cooling – 98.4 degrees

550MHz with the Card Cooler – 92.3 degrees


The Card Cooler is made with the overclocker in mind. Placing two large fans in a non-overclocked system is pretty much pointless if it operates the same without added cooling. However, it can increase the longevity of the system, but if you’re like me you don’t keep the same parts for more than two years.

The Card Cooler also makes it possible for you to cool the video board without voiding the manufacturers warranty. On the other hand, adding the cooling to overclock the video card will void the warranty. The Card Cooler does its job very well, but it does eat up a lot of power, so you have to make sure your system can handle the load.

Many people at home will try to make their own Card Cooler type coolers, but I suggest looking into the Card Cooler before doing so. The price of $20 is worth the cooling it delivers.
