Some of the other sizes in this series are pictured with fans, is this one not meant to be used with them? How can I keep it cool without them? Also, it doesn't give an instruction manual- what's the procedure involved to install these and get them accepted by my system?
Frankly, memory doesn't produce much heat. The memory sticks that you bought have very righteous heatsinks, possibly not necessary. As long as your system case has decent airflow, you should be fine. Just don't suffocate your system.
To answer your second question, I need a few things from you.
-What motherboard do you have?
-What case do you have? Have you modded it at all? If you have, let me know.
I have a Crosshair Formula IV and a Coolermaster HAF 932(unmodded). The case apparently came with a side panel of a plexiglass window instead of the other side panel that has a 230mm fan and a partial plexiglass window.
When working with RAM beware of Electrostatic Discharge. Electro static discharge can damage computer components. Walking across a carpet can generate up to 12,000 volts of ESD (electro static discharge). Electro static discharge is especially a problem in dry and cold climates.
At the very least, you should touch the bare, unpainted metal of your computer case frame before handling any computer components to prevent damage to any parts in your computer.
