It's actually NOT a problem.
You can easily bring down those temperatures if you wish with a better cooler though, as well as improving the case fans if they aren't adequate (such as adding a front fan if none exists).
I can't find any documentation but I believe the general consensus is that the CPU danger zone is around 95degC or so (at which point it will actually just crash your PC rather than damage itself). CPU's do wear out quicker but even 75degc is no big deal.
Factors which affect CPU temperature:
1. CPU cooler
2. case fans
3. ambient room temperature
Most modern motherboards need a PWM fan on the CPU cooler to support fan control. You want fan control to avoid unnecessary noise. You may have to enable it in the motherboard BIOS and also use motherboard software.
There are several good coolers if you require one.
BTW, you have a socket 1155.
For $30, this is a good cooler. I bought one for my sister and the fan had a slight tick so I replaced it with a compatible PWM fan with variable fan speed.
