Do you know of any app/sw that shows cpu, gpu, etc temps/details on the taskbar? Something like CoreTemp but with more information. The closest thing I've seen so far is Rainmeter using hwinfo but the numbers are overlaid on the desktop wallpaper.
Somewhat adequate at stock settings unless you live somewhere with high ambient temps. But if you overclock, it's the first thing you'd need to change.
Compared to others... It beats other stock cpu coolers but aftermarket coolers will be better.
