Many people worry too much about the temperatures of their components. The thermal limits that some of these components can endure before failing is quite extreme. Heck, check out the specifications provided by your manufacturer if you are in doubt.
Here is a good post about the subject. You are basically safe so long as you don't put your components in a wool bag or something. I have seen graphics cards, for example, comfortably operating under load at over 80 degrees C. That is an insane amount when you actually think about it, but this is what they were designed for. The same goes for CPUs.
Still, don't become too happy though, because heat will cause your component's lifespan to deteriorate, so it is wise to invest in good component cooling, whether this be case fans or cool water cooling setups (they even offer all-in-one units for sale now). I personally water cool all of my components because that is how I get the most cost for performance efficiency, but it is ultimately up to you and your budget.
