I7 3.4ghz CPU Keeps overheating

cpu temp is going up to about 94C when using the computer for minecraft, it used to be about 40c max, but now its idelling about 40C atm
I Just replaced the thermal paste again today hoping it would fix the thing, since it did the last time for awhile,

STOCK FAN COOLER

the CPU is a i7 2600k 1155 socket, I don't bother overclocking since its more than enough, but thing does overclock itself from stock, to about 3.8ghz
Mother board is a Gigabyte Z68X-UD3H-B3
Graphics Card is a Asus GTX560 TI
Ram is two 4gb sicks of kingston HyperX DDR3 1600 CL9 240 pin

I've got windows on a 250gb hdd, and my programs on a 500gb hdd,
got a 650watt psu


Just started playing minecraft again when the temp got down to 30, its its steadyly been climbing from 30 to 40 to 50 to now about 66.

Any ideas what is the problem and how to solve it?

When you say it "overclocks itself" I have to assume you are talking about TurboBoost. I am not aware of any system that actually overclocks itself without user intervention.

Take a look at the Task Manager > Performance Tab.
What is your CPU usage at Idle?
While playing Minecraft?

You say you replaced thermal paste. I have seen cases where folks have used too much thermal paste - enough to actually insulate the CPU from the heat sink. Thermal paste should be used sparingly, just enough to coat the surfaces with a thin film, and definitely not so much that there would be any "squeeze-out".

Does your heatsink mount with those plastic/nylon push pins? I don't trust them. My build is socket 775, and after some time, the temps began to increase. I bought a heatsink that mounts with screws & bracket. It makes a tighter contact between heatsink & cpu. I have had no more problems with high temps.

The stock cooler should do better than that. I notice in your system specs that you have water cooling on the way. That is over kill for someone who does not overclock. If you're not going to be doing any serious overclocking, something like a hyper 212+ or 212 Evo would be good and it's relatively inexpensive. It is much better than stock, and will take the heat of overclocking pretty well. The amount, method and type of paste used can make a big difference too. There are many ways of applying it, but here is the way many people do it.

Gday essenbe.

Disregard my system specs. This computer I'm talking about is a friend of mines.

I have suggested to him to redo the thermal paste and think about a better heatsink with brackets rather than plastic clips

Great suggestion. If you are doing no overclocking, you can get some excellent heatsinks for little money. They work well even if you are doing minor overclocking.
