Hello, your questions will be in bold text, my answers will be in normal text.
Is the thermal paste necessary, and if so how much should be applied?
Thermal paste/grease is used to help fill the gaps/scratches that are sadly part of the machining process at the factory when the heat sinks are molded and surfaced.
The thermal paste helps fill those imperfections to allow better heat transfer from the CPU heat spreader to the heat sink.
It should be kept in mind, that you are trying to full the scratchs, so it should not take much of a layer thermal paste to do this.
A thin layer is ALL that is needed, because adding too much thermal pastes can be just as bad as adding a piece of cardboard instead.
In otherwords, if too much is applied, it will force the heat sink even under pressure to float above the processors heat spreader and cause poor heat transfer to result.
So the object is to apply just enough to lightly cover the spreader and not a more.
When installing two SATA hard drives, do you have to set one as master and the other as slave? How?
SATA hard drives do not need to be set as master and slaves because they do not share the same data cable like E-IDE/PATA does, those have to be set as MASTER and SLAVE because they share the SAME electrical connections in the cable.
SATA drives use a seperate cable per each hard drive, they use their own seperate ports SATA 1, SATA 2, SATA 3 and SATA 4.
In the BIOS they are set as SATA 0, SATA 1, SATA 2 and so on.
Now unless the drives are set up as a SATA disk array, one is like a MASTER on SATA 0 and the other is like a secondary drive as SATA 1.
My case (Cooler Master Gladiator 600) comes with an HD Audio and AC '97 connector. What are these for and where do I connect them?
These would connect to your motherboard connectors if they are available, you would need to check your motherboard manual for the connectors if it has them, they might be called PANEL or CASE connections, this would allow you to connect devices from the front of your computer tower rather than having to access the rear panel where the motherboard's rear panle connectors are.
There's a couple of SYS_FAN and a PWR_FAN inputs, but my fans only have the 4 pin connector to connect to the PSU. Are these obsolete or something?
Some motherboards allow for the 3 pin cooling fan types, they have a 12 volt +, a 12 volt ground and a rotation sensor wire, to detect fan speed. These fans can also be controled by the BIOS to speed up or slow down as needed according to the sensor reading, more voltage or less voltage is applied to the fan as required to speed up or slow down the fan speed.
Cooling fans that are directly wired to the PSU, do not have this ability, since there is no sensor readings being sent to the system BIOS through these power circuits.
The Processor cooling fan for example should always be powered through a power connector on the motherboard.
Hope this answers your questions.
