A quote from the article:
>> NZXT Sentry LX Fan Controller Review
The NZXT Sentry LX is a great looking fan controller that allows setting and monitoring the speed of multiple fans and monitoring up to five channels of temperature along with displaying the time and date. The unit is easy to install and setup and the accuracy of the displayed fan speeds and temperatures are good for all channels. One potential watch-out is the 4W per channel power limitation.
