heat sink & temps

[jesr5]

Hey I'm trying to do alittle ocing & keep temps down using air.when checking temps some programs list processor temp(which is ok mid 40's) but also list core temps(which are ocassionaly in mid 70's at full load/stress test).I got a xigmatek S963 on an E8400 on a asus P5Q.I dont think I can go with a 120mm heatsink because my apevia x-discovery case has a 80mm side window fan which blows directly on the top of the heatsink(clearance).I also have a pci slot fan under my videocard.2 80mm intake fans on front.My S963 has the slimmer sides facing front & rear.The larger sides up & down with the fan on the bottom side drawing or sucking the air into the fins(fans blows air onto heatsink).I always thought you wanted the fan blowing away from the heatsink(removing heat).Anyway my question is can I rotate my heatsink 90 degress so that the fan would face the front of my case then the fan could catch the air from the 2 front 80mm fans & push it through the fins of the S963 toward the rear exhaust(120mm).I also have shin-etsu g751 to reseat the S963.

Always go by core temps. Consider a top down cooler like

or

so the side fan will blow cold air on the geat sink.
For tower HS to keep front to back airflow, consider TR Ultima as it is shorter or even better Thermolab BADA HS
