New Build overheating on stock heatsink?

So one day, while I was playing Planetside, I had a whim to run CoreTemp to see my temperatures and how much overclocking headroom I had with the stock heatsink while I RMA'd my AIO liquid cooler because of a derpy backplate. Lo and behold, I nearly had a heart attack when one of the cores was at 91C, and every other core was in the mid 80s. I immediately closed Planetside and watched it drop to 40C almost instantaneously.

Did I get the bottom of the barrel in terms of the silicon lottery, where my chip won't even run clear in stock speeds? I don't think it is the thermal paste's problem, Intel's heatsinks all come preapplied so I assume all I have to do is snap the 4 pins in place.

My computer specs are:
i7-4770k (stock speeds, 3.5/3.9 ghz)
Asrock Z87 Extreme4
GTX 770
Fractal Design Define R4
 
Solution
1. Detach heatsink.
2. Clean heatsink and the CPU's IHS (Integrated Heat Spreader, the metal on top) with isopropyl alcohol and a lint-free cloth/rag/etc. Make sure there is no thermal paste left.
3. Put a dot in the center of the IHS (picture below). About that size or little bigger.
4. Reseat heatsink.

I had a similar experience with the i5 4670k running Intel Burn Test with stock cooler. It hit 94*C. within about 10 sec. Test over!

Except IntelBurnTest stresses the CPU even more than Prime95. Planetside 2 only uses 4 cores, and it's usage oscillates between 20% and 50% of the cores. If 50% can cause 91C, I shudder to think what an IntelBurnTest would do.

Any ideas? I know Haswell is a lot hotter but to be hotter than many laptop CPUs is a bit pushing it.
 


You might try replacing the Thermal Interface Material that comes on the stock cooler. When I took mine off, there was evidence of 'gaps' and uneven coverage by the stock TIM compound.
