Since the fan on the Susurro is temperature controlled, we decided to include 2 results for each test setup; One where we let the “fan” decide which speed it’ll be spinning, and one where we set the fan to 100% “manually”.
You can permanently
set the fan to full speed by removing the temperature sensor. So unless you’ve got some good soldering skills, this modification will turn the fan into a normal, none-temp-controlled, one. Test Setup 1: Overclocked & Silent
Since we are using the exact same setup as in our last roundup we’ve included results from previous heatsink stressing tests.
With the CPU overclocked the 92mm fan is spinning at 3100rpm on auto setting, which unfortunately makes the fan quite noisy at 49dBA. However this was nothing compared to having the fan run at full speed, which translated into 3600rpm and 61dBA! While this fan can deliver the airflow needed to keep the CPU from overheating, it’s not recommended to use it on an overclocked CPU.
How to read the charts below: We have had some inquiries about how we displayed our temperature and noise results using the charts in Excel, we put dBA and °C on the same bar to improve the easiness of reference between noise and performance. Never would we consider adding °C to dBA to obtain a valid number which we use to deduct overall performance from. However our aim is to give some kind of relation between the two and we color code them differently so you can easily make out what FAN is making what noise, and at the same time, know how much air it is pushing.
The charts below are sorted by CPU temp (High to Low), and while this does represent the pure performance side of things, you should not neglect the dBA bars in the charts.
As you can see from the results above, the Susurro is simply not build to remove a large amount of heat silently.
Test Setup 2: Stock speeds & Silent
When we run the CPU at default speeds the Susurro easily beats the A64 stock HSF, but trails the X-Mars which has 2 heatpipes in its design. With the auto setting the fan only spins at 2300rpm.
Now we haven’t mentioned the effectiveness of the 92mm auto-sensing fan, once the CPU is allowed to cool down the fan speed drops below 1000rpm an you are unable to hear the Susurro.
The Susurro will fail to impress the overclockers out there, but those people who runs their CPU at stocks speed, use their PC for office work (or a small HTPC system) they will find the auto-sensing 92mm fan an excellent asset of this compact heatsink. An attractive price, easy installation and compatibility with future AMD platforms make the Susurro a interesting product for the less demanding user.
Very easy installation
Silent operation for Office-PC class system thanks to Smart Fan
Not meant for overclocking, high temperatures and noisy
