Acoustic Samples: Listen to this Heatsink!

The Coolage Freezer Orb heatsink is pretty quiet when its fan is controlled by a Pulse Width Modulation (PWM) compliant motherboard BIOS. With a rated fan speed of between 1000RPM and 2800RPM, the Freezer Orb can alternate between moderately audible and quiet depending on the processor's thermal load. Since we have to test with a 3-pin power connection, the Freezer Orb defaults to full speed which creates just under 50 dBA noise. To listen to this heatsink in operation, be sure to click on the little headphones icon below and play each of the sample MP3 files.

Sound Level Measurements: Which Heatsink is Quietest?

Listening to the actual noise a heatsink makes allows you to hear what pure numbers alone cannot get across. To further emphasize FrostyTech's reliance on cold hard facts when evaluating a heatsink, we also take noise level measurements with a sound level meter.

FrostyTech Heatsink Noise Level Measurements
Noise level Decibel measurements of each heatsinks' fan in operation are taken with the aid of a sound level meter and sound isolating enclosure. The values may be higher than the mfgr's listed specs, but are directly comparable to one another. Measurements are made on the dB (A) scale, lower values are best. Information on Frostytech's test methodology is available here.

Noise Level (dBA)

*Unless noted, for reference heatsinks with variable-speed fans only the 'high speed' (12V) fan noise measurement is included in the comparison sheet; more detailed results for the low fan speed (~5V) tests reside in each specific heatsink review. ** 'AMD' denotes compatibility with socket 754/939/940 & AM2 processors where applicable. 'Intel' denotes compatibility with socket 775 platform.

If the 95mm fan on the Coolage Freezer Orb is spinning at full speed the heatsink produces 48.9 dBA noise. In an enclosed computer case this won't be too audible. In comparison, the stock Intel Pentium D heatsink produces about 47.5 dB at its fastest speed, the stock Core 2 Duo heatsink just 36.7 dBA. When fan speed is reduced to 1000RPM, the Freezer Orb becomes even quieter and noise levels decrease to 34.1 dBA.

Surface Finish and Flatness

Surface finish is an important factor that we all look for when holding a new heatsink. Flipping a cooler over to see how well the base has been machined is a quick way to judge the attention to detail that was put into making it. The following test involves the use of a Surface Roughness Comparator, which offers a concise cross section common machine surface finishes.

The Coolage Freezer Orb heatsink has a surface roughness of approximately 63 microinches, which is considered satisfactory. The base of the unit FrostyTech evaluated was slightly convex in both axis. Now let's see how this baby handles the heat compared to a selection of top of the line AMD and Intel heatsinks!
