I am building a system using the i7-990X LGA1366 processor. I know the processor can generate an incredible amount of heat, so I want to make sure I have everything properly set up before powering it up.
I have searched through this site, as well as several other sites searching for information on cooling.
In particular, I want to make sure the heat sink fan is oriented correctly over the CPU.
An Intel video re system integration said to install the heat sink fan toward the front of the computer. That presents a conflict with the computer case. I am using a Cool Master HAF X type case. The orientation of the motherboard is such that if I would try to orient the fan toward the front of the case, the heat sink thermal interface would not be oriented correctly. (The heat sink copper interface and the chip surface are more rectangular, so ideally, I would think the heat sink mating surface would be mounted somewhat similarly to the orientation of the CPU. I hope that makes some sense.)
I have also searched in an attempt to determine the direction of airflow through the heat sink cooling fins. (I will be able to determine this once I power the system up; but, I'd like to make sure everything is right before powering the system up.)
Is the fan mounted to the heat sink assembly "pushing" air through the fins of the heat exchanger, or is it pulling air. (Based on the fact there is no shroud, and the integration video I viewed said that the fan should be oriented toward the front of the computer case, I am thinking that this is probably a pusher type fan arrangement. Being that I understand most air flow would be from the front of the case to the rear, that would make sense having the fan mounted in that orientation on most systems.)
This Cool Master case actually has 4 fans, plus the power supply fan. Two are supply and two are exhaust. There is a fan immediately above the CPU. It is exhaust, so it would make sense to have the fan/heat sink oriented so that the fan is below the heat sink (with the heat sink between the Intel CPU fan and the exhaust fan on the case).
This makes pretty good sense as I write the information down. I hope to confirm that the fan on CPU is indeed pushing air (as opposed to pulling it).
