Fan Noise
In order to give a measurement of how loud the fan is, we used an IEC651 Type II sound level meter on the dbA slow setting.
The distance between fan and sound level meter was 10 cm. Please note that this is very little, compared to the "standard" measurements, which are made at 1 m distance. We had to do this, to get proper readings with our sound level meter, because we obviously can't spend thousands of dollars on audio measuring equipment.
The cooler was connected to an external lab PSU. 12V is the standard rated fan speed. For easier comparison we also tested the fan noise at 50% (6V).
Wow. If you are looking for "silent", then the Evercool Turbo 2 should be on top of your list. As additional testing I hooked the fan up to 5V, which was still enough to keep the X1800 in safe temperature levels under load. The fan was so quiet that I had to put my ear about 10 cm away from the cooler to even hear it spinning.
Value and Conclusion
- With a price of just $20 this cooler is coming at a very good price.
- Very Quiet
- Very affordable
- Good performance
- Wide compatibility
- Easy to install
- Air not vented outside the case
- Does not cool memory
If you are looking for an alternative to Arctic Cooling's coolers you should check out the Evercool Turbo 2. It offers good performance, very quiet operation and a good price.
When you are building a system with focus on low-noise instead of performance, this cooler is actually the best on the market. At 5V it's whisper quiet (technically a lot quieter than a whisper).
Being able to be used on pretty much all cards from NVIDIA and ATI is another plus. Other manufacturers have a load of different products from which you have to get the right one, and find it in stock. Evercool even includes some "universal" mounting tabs which should let you use this on any card that has mounting holes.
However, there are a few minor drawbacks. The memory chips are not directly cooled, only by airflow. Based on our testing this seems to be sufficient. Another point is that hot air is not exhausted on the backside of the case so you may need an additional case fan to get rid of the heat.
