The AMD Athlon XP 2600+ processor. Typical OEM packaging is like this. Bubble wrap surrounding the processor enclosed an antistatic bag. The processor is inserted into a small foam square to protect the prongs.
It's important that the CPU Cooler provide enough cooling capacity for the processor, but it's also a consideration as to how much noise it makes. The CPU Cooler is perhaps the primary noise factor component. The Thermaltake Volcano 9 CPU Cooler I chose is sufficient for up to Athlon XP 3400+, so I have room to grow. The, um, cool thing about this CPU cooler is that it can be installed in three different ways to give you the balance you desire over cooling effectiveness and noise level. The third picture below is a blow-up of the contents of the goodie bag shown circled in blue in the second picture.
The white blob in the clear package in the third picture above is the thermal compound that Thermaltake includes with the CPU cooler. That's very nice of Thermaltake to do that and I'm sure it does the job just fine, but I prefer to add a few bucks to my overall cost and get a thermal compound that's really first rate, namely Arctic Silver 3.
The other items in the goodie bag are: the black cable has the thermal sensor on the end of it, the small blue square is actually a jumper used to set the Volcano 9 to a particular configuration, and the white square is actually double-sided thermal sticky tape used to stick the thermal sensor to the bottom of the processor.
