I was extremely pleased with the GELID Silent 12 TC and PWM. They
seem to be designed very well and perform exceptionally. The performance
to noise ratio is also excellent, making these fans worthy of having
"Silent" in their names. The installation is easy, thanks to the rubber
mounting posts which I prefer over screws. Even the MSRP for these fans
is attractive at $10.80 for the TC and $10.50 for the PWM.
