I've Been Using an I7-3770K For The past 2 years Without Overclocking With The Stock Cooler.
I've noticed That The Temperatures Have Shot up a lot.
About 40-45 Degree Celsius When Idle And 80-85 When under load during CPU Intensive Games.
Is this Cause Of Some Dust Or Should I Replace The Stock Cooler ?
Will it Cause Harm To The CPU in The Future ?
Any Other Solutions ?

Rest of The Setup :
cpu : Intel i7-3770k
mobo : Asus p8z77-v-pro
ram : 16 gb corsair ddr3 ram
Hdd : 1 Tb WD black
Ssd : 120 gb corsair neutron ssd
OS : Windows 7 premium
Case fans : X3

After 2 years it might be time to replace the thermal paste between the CPU and heatsink. It loses its effectiveness over time and might be the main contributing factor to the heat increase.

It isn't healthy for the CPU to run over 80c for an extended period of time, so it would be best for the hardware not to push it until you get the cooling sorted out.

IF, after replaing the thermal paste, the temps are still a bit too high, then replacing the stock cooler with a good quailty aftermarket heatsink like the Cryorig H7 will certainly solve the probelm.

Also, IvyBridge does run hot anyway. Intel used a different inferface material under the cap in order to make overclocking much harder, as a response to their making SandyBridge such a good overclocker. Naturally, people tried replacing the material with something better, and doing so can reduce load temps by as much as 35C (plenty of youtube vids on this). Jamie3d's summary is spot on, those are basic things to try initially, but IB sadly is just kinda hot by default.

PS. A decent, cheap, used cooler like a TRUE will also do a fine job, if you can find one. I typically get them for about 15 to 20 UKP, fan included. A TRUE can cool a 5GHz 2700K no problem.

It's not really hot, it just takes time to get the heat from where it is generated to the IHS. so the cores 'spike' in temp really easily and don't have a consistent temp. Swap for a nice big air cooler and you'll be fine.
My 3570k at 4.3 runs at 60-65 on air, so it can be done, on stock cooler i'd be at 90+

Your 3570K runs that cool because it doesn''t have HT. :D Not having HT reduces load temps by 10C immediately. My point is that a 2700K with HT can run at 5GHz on air at only about 75 or so, which is impossible with any unmodified IB. See:

https://www.youtube.com/watch?v=XXs0I5kuoX4

From the toms review on the 3770K:

"The main difference between overclocking these two architectures, aside from
Ivy Bridge appearing comfortable at just slightly slower frequencies, is that
Intel’s 22 nm-based chips also run significantly warmer (somewhere around
10°C higher at each CPU’s maximum stable overclock)."

Many users found IB CPUs to run much hotter than review sites. That youtube example is pretty typical.

As said above, you can replace the thermal paste and see if that solves your issue.

You may also want to invest in an aftermarket cooler, as you won't be overclocking on the stock one even though you have a capable CPU and motherboard. If you are willing to buy a better cooler, what is your budget?

Note my comments about IB being an inherantly hotter chip refer to the interface material inside the CPU, between the chip itself and the metal cap, as opposed to the paste between the CPU module and the heatsink (heck, even Marmite can be used as a thermal paste, I tried it during a conversation about these issues with someone at Thermalright, it worked surprisingly well, almost as good as AS5. :D) But yes, replacing the basic thermal paste is a first test to do.

aditheoggy, are you in the UK? If so, then I have a tube of thermal paste you can have for free. I also have some aftermarket air coolers I can do very cheap (don't need them as I've switched to water AIOs).

No, I live in India .
I Think i'll Try Applying a New Paste On the CPU
Thanks For The Answers.
