The first port of call for the test results is the CPU tests. The tests were run with the X3 720 at stock and overclocked states. The overclock used was 3.6ghz @ 1.45v.
Stating by browsing over the results from the TX3 we see it did reasonably well. Holding the chip under 60°C in its hottest state and keeping what you would assume to be the second hottest state at 33°C. The idle overclocked temperature actually landed higher than the stock loaded, which was a little odd. All round though the TX3 faired well here. Nothing astronomical but it certainly did its job.
The next graph shows us the CPU results from the 212+. These, as with the TX3 above, are quite reasonable. The 212+ actually had some higher results on the stock setting, but these were not more than 2°C. The 212 shone most on the hottest state, overclocked loaded. Here it beat the TX3 by a full 10°C to hold the chip and a nice cool 48°.
The simulated load tests were also conducted with an ambient to 20°C (+/- 0.5°C), and as with the other heat sinks tested, the points of 50, 100, 150 and 200w were chosen to test the heat sinks.
The test results here showed a rather poor show from the TX3. The temperates skyrocketed, only just beating out the Intel stock heat sink by a small margin. This really doesn't bode well for the small heat sink as it indicates it could easily have a hard time keeping high end quad CPUs, even 775 based ones, down at a reasonable temperature. The 212 to the other hand produced some fantastic results on the tester. Inching out every heat sink and fan it was pitted against, even its sibling the N520 and the acclaimed OCZ vendetta.
Finally, on the last page we draw our conclusion...
