Cooling And Temperature

Athlon Vs. Atom: Duel Of The Energy Savers
By

Since the Athlon 64 2000+ is a desktop processor, a commonly-available cooler can be used. For the test we used the boxed cooler, which usually comes with the 45 watt Sempron LE-1100 and its cooling element is made completely out of aluminum. Since the cooling power of the cooler is enormous compared to the heat released from the processor, we only measured a temperature difference of 2 °C between idle and full load operation. With the fan turned on, the temperature does not exceed 27 °C.

Here we have disconnected the fan and removed the frame.

Because of the size of the cooler in comparison to the energy consumption of the Athlon 64 2000+, we measured the temperature after one hour of operation. With just the passive aluminum cooling element, the core temperature stays at 39 °C while the processor is idle; at full load, it does not exceed 55 °C after one hour.

The 780G chipset, due to its low energy consumption, can be sufficiently cooled using only two small coolers. The Athlon 64 2000+, with its relatively low performance, limits the onboard graphics, and thus the integrated GPU never operates at high-load conditions, so the northbridge can be run without active cooling. Just to be sure, we ran Gigabyte’s GA-MA78GM-S2H board with the AMD Athlon 64 2000+ for over 12 hours at 100% CPU load without problems.
