Early this morning, I managed to replace the GPU cooler for my old Zotac Geforce 8800GT.
The old Zalman Fatality GPU Cooler (Reserved)
1. The GPU cooler itself

2. Before replacing the GPU cooler

The entire ordeal took around 45 mins to an hour. This is because the instructions were quite small (with multiple languages). It was quite intuitive for me as I have done this every now and then.
1. Xigmatek Battle Axe with my Zotac Geforce 8800GT (overview shoot)

2. Xigmatek Battle Axe with my Zotac Geforce 8800GT (side shoot)

3. Xigmatek Battle Axe with my Zotac Geforce 8800GT in my old PC
*As you can see, it takes around 2.5 slots or more.The difference of the idle temperature between the Zalman cooler and Xigmatek cooler was around 6-8c (with both running at full speed).
Xigmatek cooler @ full speed is a lot quieter than Zalman cooler @ full speed.
Previously with Zalman cooler, it was around =56-60c
Now with Xigmatek cooler = 50-52c
Please not that this was tested in a room without air conditioning, will update results when the aircon is switch on later.
I would not be able to test the load temperature as my old PC has no games in it at all.
Pros:
1. Silent (even at fullspeed)
2. Fans can be replaced if needed be.
3. Quite easy to fit in
4. Wide compatibility
5. Good availability
Cons:
1. Takes up more than 2 slots
2. Instructions not as clear as the Zalman counterpart
I would recommend this to anyone who are quite annoyed with the heat and noise generated from their stock coolers.
