Today we present you all the heatsink results we gathered in the last year, tested on our Athlon 64 setup, the complete list consists of 36 units which were compared to each other and the stock aluminum AMD heatsink.
Second part of the roundup consists of inaugurating our new Intel S775 test setup, we do this by re-testing the acclaimed Scythe Ninja and compare it to 6 newcomers. 37 Heatsinks Compared
These were the heatsinks tested on the Athlon 64 setup:

AMD Test Setup and Methodology
All heatsinks except one (MACS TEC) were tested with the case in the exact same environment, with ambient noise levels consistent. The MACS noise level was tested with higher ambient and at a different angle/distance. It can not be directly compared to the other results, and thus its noise levels will be left out the comparison chart on the next page.
Athlon 64 Setup
|CPU || Athlon 64 3200+ @ 2400 @ 1.7v vcore |
|Mainboard ||DFI NF3 Lanparty|

Silverstone EFN-300 300W Passive Cooled PSU
Maxtor 120GB IDE HDD
in-take temperature was measured at 22°C for all tests, but temp fluctuations, different mounting and user error can account up to 1-3°C of inaccuracy in the obtained results. Please keep this in mind when looking at the results. Each heatsink was tested repeatedly; if we got questionable results the test was restarted.
Noise level of each HSF combo was recorded with SmartSensor SL4001A, the sensor was placed ~50cm away from the case. The lowest dBA reading in the test room was 32.5dBA with everything turned off! Noise produced with system running without HSF fan: 34dBA @ 50cm
System was stressed by running K7 CPU Burn for 30min (after Thermal Compound's burn-in); this application pushes the temperature higher then any other application or game we've yet encountered. Speedfan was used to log maximum obtained temperatures.
Arctic Silver kindly send us their ?Lumière? thermal testing compound which has the same colour as Ceramique, but only a break in time of 30min!
Arctic Silver's ArctiClean was used to clean off thermal paste of the CPU and heatsink between tests
Fans used for comparison
To eliminate as much variables in the tests we test each heatsink with a "reference" fan if it can be mounted.
Delta NFB0912L 92mm: 42CFM
Papst 120mm 4412 F/2GLL: 40CFM
CPU Speed and Noise Measurement
Since we’re only using an Athlon 3200+, it would be interesting to overclock the CPU so its maximum heat output increases and it can simulate a higher clocked Athlon 64.
We recently purchased a power meter similar to this. Doing a few basic measurements with the test system gave these results for full system wattage usage.
Athlon S754 3200+ @ 2200Mhz - 1.5v: idle: 67Watt / Load: 125Watt
Athlon S754 3200+ @ 2420Mhz - 1.7v: idle: 78Watt / Load: 165Watt
In the days of the Athlon XP an increase of 0.1v vcore would result in 4-6°C higher CPU temp, so without much surprise the temperature results in this roundup with the 1.7v Athlon 64 will be much higher.
Noise was recorded approx. 50cm away from the case at an angle, here's a (very bad) drawing of how the dBA meter was position opposite the case and the test-room.
Green box = Sonata II # White Dot = dBA meter
What was measured?
The CPU temperature was measured with SpeedFan and highest value recorded
PWM temperature through SpeedFan, this represent the area around the CPU socket, the power management caps which you see on a motherboard, they are there to make sure the power which is fed into the motherboard coming from the PSU is filtered and delivered the CPU and other components. Too high temperature will cause Vcore fluctuations which in turn causes system instability.
