Here is a trick to test to make sure that your HSF (heatsink/fan) is seated well. Reach in and grab each of the four twist clips and pull straight up. If any of them come up than the stock HSF isnt seated right. When you seat the stock HSF on the Intel® processors you do them in a cross pattern so bottom right to top left, than bottom left to top right and this will help ensure that you get the best seating of the HSF.

Hi Christian and thanks for your reply
I turned off the computer and did what you described. The twist clips were quite firm and none of them moved with repeated pulls. I already expected them to be so, as it was my technician who installed the processor for me.
Could it be perhaps that the fan's max speed isn't as fast as it should be, for some reason? I use a DZ68DB mobo with the latest BIOS and a 650 Watts power supply.
