I used a temperature probe to test the change that the Spot Cool causes. I put on a modest overclock (10% to both CPU and RAM) and tested the results.
|W/O Spot Cool
|W/ Spot Cool @ max
|W/ Spot Cool @ min
The CPU saw no change as the airflow was not directed at the heatsink. The RAM did see a change that made my PC much more stable and allowed me to keep the overclock whilst gaming. Obviously, you can change where you want the airflow to go. Which means that you can choose to cool your Northbridge, or PWM. This is of special concern to me, and those who own a mobo made by Asus who have a heatsink by the CPU which cools both the PWM and Northbridge by heatpipe. Directing the Spot Cool at this saw the degrees fall away, serving both to extend the lifetime of the mobo components and to allow a greater overclock.
The Spot Cool seems to be more useful as a problem solver than a permanent cooling solution. For example, if you thought that you were having issues with the Northbridge overheating, then you could use the Spot Cool to diagnose the problem. With that said, I am definitely going to keep the Spot Cool doing its thing on my RAM; not only because it lowers the temperatures but because the LED’s looks damn cool :).
Noise wise, the Spot Cool is quiet. Even at max RPM you’re not going to be annoyed by the fan noise. When I’m on my PC, I use headphones, so the Spot Cool is always at max which doesn’t bother me.
