It is very simple.
Obviously I will read any instruction the fan comes with but im new to upgrading computer and still learning.
1. You will need to know what size fan you need for the allotted slot in the back of your case. "Usually", they are 80mm fans that go there, but they can be different than that. My parents dell requires a 92mm. My new case will require a 120mm. I highly doubt that yours will be under 80mm. The best thing for you to do is measure the distance between the screw holes(not diagnally) up and down or side to side. Then tell the guy at the computer shop that and that will help him know.(rough instructions, but you get the point)
2. How does the fan get its power? There are two ways. It will have a 3pin connector(see link below) or a molex connector, it may provide both. Since you are unsure, and your case doesn't have a window, I would just install the fan using a molex connector(see link below) since you aren't worried about looks or anything.
2a Optional A 3pin connector would connect to the motherboard somewhere. If all you are able to get is a 3pin connector with the fan, you may want to post back so I can research your motherboard further and see if you have a extra 3pin connection on your motherboard. If not, there are adapters.
3. Open the case up, screw the fan to the case. (All 4 screw holes much match up).
4. Connect the male molex connector to the female molex connector from your power supply.
5. Power up the computer and make sure the fan is spinning BLOWING AIR OUT in that particular location.

Hope that helps!
EDIT: I forgot to mention that on any fans specifications the higher litres per minute the better, but keep in mind you want lower dba(decibals or noise). For example, the 80mm fan that you have linked us too moves 900 litres/min and noise is 31dba. Just as an example to help you, 1200 litres/min with a 25dba is going to move more air but be quieter. SEE?

I have been running my GPU fan at 55% for a few hours now and have turned the fan up on my PSU to max (its adjustable with a knob) and the idle temp is slowly creeping down, its at 54 oC now and still falling but very slowly. I'm sure with another fan I can get it down to a more comfortable idle temp. What would you say is a good idle temperature and a good load temperature ?
Oh Ferrari, I have a few unused molex connectors that I could use for the fan but I know one 3pin socket is being used by the fan that is situated on the side of my case but when I was replacing the PSU I didnt notice any other 3 pin connectors on my mobo.

Just connect the fan to a free molex connector from the PSU then. If you can't find a fan at the computer shop that connects via molex(which you should be able to) you can by a 3pin to molex adapter extension. It will look kind of like the pictures I linked you to but a 3pin on one side and a molex on the other.

That's simple, the lower the better (load and idle) You just want to stay from 100 C. The temperatures you are reporting now seem good.

Just play with the settings on the GPU, PSU, and any other cooling device you have control over. Trial an error will be the best way to find a "cool" temperature and a "noise" level you are happy with. Maybe you need to have a setting for gaming and a setting for normal usage. SEE? Geeks like me love that stuff

Also, while you are inside the case is a great time to make a visual inspection of any crevices, vents, or openings where air comes in and/or dust/nicotine can build up. ESPECIALLY the heatsink for your cpu. Dust coverings on your heat sink will prevent the heat sink and fan from operating at peak performance levels. If you have blockage from any openings on your case where cool air can come in or go out will directly affect the temperature inside your case, which directly affects the temperature of everything inside the case. You should perform this type of inspection periodically. Especially if you or your family smokes cigarettes, cigars, pipes, etc. Or, have a dusty area where you keep the computer. i.e. unfinished basement.
