When you're overclocking, or even just have a higher-end gaming rig, you probably like to know just how hot things are getting inside your case. More so with overclocking, as you tend to run the risk of pushing your components a little to far and frying them due to the excessive heat. Usually your motherboard will come with a nice hardware monitoring utility, but I don't generally like those, as they take up valuable real estate on my desktop. Not to mention you can't always check temps during a gaming session without minimizing your screen. I prefer hardware gauges, such as the new Sentry LX from NZXT, which I have had the pleasure of using.
