CPU reads 80+ degrees C...on boot?! Uh, thoughts?

So, I've had this system for a few months, no problems:
-EVGA 017-P3-1175-AR GeForce GTX 275 1792MB 448-bit DDR3
-CORSAIR DOMINATOR 6GB (3 x 2GB) 240-Pin DDR3 SDRAM DDR3 1600
-Intel Core i7-920 Bloomfield 2.66GHz LGA 1366 130W Quad-Core Processor Model BX80601920
-EVGA E758-TR 3-Way SLI (x16/x16/x8) LGA 1366 Intel X58 ATX Intel Motherboard
-STOCK cpu heatsink/fan (Yeah, I know, bad. But:
-I am not overclocking whatsoever. )
Whilst playing Modern Warfare 2 the other night, I was getting some goofy crashes where the whole system would stop responding and just display the image where it crashed. Darnit. After doing this about every 10-15 minutes, I started checking for new drivers for my GPU (installed), and then checked my temperatures.
My CPU cores were running at about 93 degrees C, with one of them running at 99. Shitshitshit, turned it off, blew dust out, insured heatsink was on the CPU and all fans were running, left it to sit overnight.
-It's notable that the case temps were reasonable ( I forget what exactly) and my GPU was about 40-45 degrees C.
Turned it on the next morning, thinking to monitor how its heat went up, and right after sitting cold all night and booting, it was reading about 80 degrees C for my cpu cores. How in the hell is that possible after sitting in a 60 degree F room for eight hours???!!!
These readings are from Core Temp and the EVGA E-LEET tools. Is it possible the sensors are damaged? Or can anyone think of another reason I might be getting these readings??
Edit: After running for an hour, the CPU is idling at about 85 C for two cores, and 90 C for the other 2. >.<

edit: nm, saw that you answered that.
Did you move the computer recently? Checked the voltages within CMOS?
So, it might be worth reseating the heat sink with some fresh thermal compound.

What program are you using to read temperatures? There's a slight chance that those readings aren't accurate.
I set the fan speed to manually be 100 percent. Doesn't help, so I think it auto set them to 100 percent.
It's possible that the problem always existed but has slowly been getting worse over time with the fan's vibration.

And again, the Intel stock HSF is more than capable of handling that i7 under pretty toasty conditions. The only time you need to go to a custom cooling solution is if you plan on doing some serious OCing.
Removing then reseating did the trick.
Tried making sure the heatsink was in right, and it may be my imagination but it seemed like it may be not as tight as possible, but even after tripple checking it was in all the way, I just went out and bought some paste. cleaned out the old stuff, put on the new stuff, and made damn certain it was seated all the way.
Now it boots at 40ish rather than 90ish. Jeebus.
Many thanks all for the suggestions!!
It wasn't the paste but that it was not seated properly anymore.
Doing it over properly was the best fix.
That said, there is a difference in paste quality but on an order of magnitude smaller than this case.
Also, yes, the "CPU" temperature reported is less jittery and reflects more of an overall thermal situation, the "core" temps are direct from such and they can spike up immediately and drop quickly as well (provided there is actual cooling taking place) and tend to read higher than the former.
Most builds of i7 can operate at 100 degrees celsius

Just because they can doesn't mean you should let them do it.
Better safe than sorry.
I don't think Paladin was saying it's okay, he was just pointing out that the internal shutdown temperature (tjunction) of the i7 chips is 100c, which means that is the temperature which Intel felt it could safely reach before shutting itself down to prevent damage.
The reason this is inconsistent with what Phoenix has experienced is that the tjunction for the Core2 series of chips was indeed 70c.
without a heatsink and security mechanisms to switch it off, it would probably reach something around 400°C if it could :P
You have the power output of a cooking plate on an area smaller than a fingernail..
My i5 sits at about 60 degrees and my GTX275 at about 70 degrees at really high load (like, playing World in Conflict in dx10 mode with a really busy fight going on). I have another fan sitting here to install, but I haven't yet. Idles at around 40 degrees though.
