Hey, just upgraded my HSF setup and it's loud as hell, but the temperature is more than worth the sacrifice. I tried to setup using the sensor so it will modulate the RPM but the diagram says to put it underneath the CPU, only I find it obstructs with the pins so I can't really use it as instructed. Did anyone have this problem? Also what the heck are you suppose to use to make it stick ? the picture shows some white compound (thermal grease?) Wow this sucker is loud!
