Let me guess - using a credit card or smeared with a finger.
Really shouldn't be done like that - You should apply (depending on architecture under IHS) - Sandy/Ivy/Haswell quads are two Duals bolted together on the same die running up and down the chip so you should apply a line of paste directly up and down.
Reasoning behind this is that if you spread it out, you will inevitably end up with low and high spots - which you can't do anything about... If you do it with a line, as the heatsink bolts down you'll distribute the compound evenly - it'll also take up as much room as it needs to under the heatsink, not leaving you with high/low spots uncooled. Best way if you're brave is to remove the IHS - Intel are being cheap these days and rather than soldering the IHS on or using direct contact, they're simply shoving a Thermal Compound under the spreader and gluing it on, it goes manky after a time and the chip overheats.
You can either pull off the IHS or lap the top of the IHS - Intel seem to be inept at making an IHS actually flat, Googling will reveal some photos of Intel IHSs which are about as flat as an upturned pudding bowl. Only reason the IHS is there is for when people have chonging heatsinks hanging off CPUs and they bash them down on a desk - it's likely to place a lot of pressure on the edge of the die and possibly chip it - they're fragile - but long as you're aware of it, it won't be a problem, I've removed the IHS off of every Intel chip I've had in the past and not had a problem - remember laptop CPUs still come with the lid off because the thermal transfer with the IHS off is so much better.
Have a look on the usual XtremeSystems forums etc and you'll see loads of topics about this. Mostly related to LGA775 era stuff when I was still into computers etc, but I'd be sure there's still a load of OC'ing enthusiasts still about. I got bored when OC'ing became a case of how much money do you have... Bring back the days of 4+GHz Athlon XPs, 6+GHz P4s/PentDs and ghetto as f*ck vmodded Abit IC7-Max3s I say!
Quick rant there, sorry.
