Best Place to install a Temperature Meter probe

Solution
I would say that is more helpful.
Time and date is simply a nifty feature, its a fan controller, which alone make its worthwhile, it also gives temps (of cpu, or the fans it doesnt specify)


so would just taping it next to the exhaust be the best place?
or should i just get this http://www.amazon.com/9fox-Desktop-Controller-Regulator-Display/dp/B00IJZZE72/ref=lh_ni_t?ie=UTF8&psc=1&smid=A3U5UMLXMIVLLD will this give me the info i need?
not trying to break the bank here i know its a cheap one but its just a cool little gadget i would probably have fun playing with and it looks like it would be usefull
 


thanks for the suggestions!
