I suggest checking out this article on hardwaresecets.com. They try several methods and benchmark them. The results are suprising, especially to people that tend to use more rather than less.

Is the settup you have now using the thermal pad that came on your Evo 212? Either way, if you take off the cooler now, it's best to apply fresh paste.
Let me know hwo it goes!


I also forgot to mention, my current temps are reflecting of a 4.2 ghz overclock with JUST multiplier considered. I undervolted to -0.040 and my idle temps are the above. So I'm assuming that the idle temps are higher due to the overclock....although the undervolt should have compensated....hmmm

As far as the thermal paste,
I used arctic silver 5 as per their recommendations.
1. I cleaned both the heatsink and cpu with rubbing alcohol and a coffee filter.
2. I rubbed arctic silver 5 into the heatsink with a credit card, and removed all excess with a coffee filter so it was "tinted" slightly.
3. I did the "line" method of arctic silver across the cores in a vertical 1mm line of arctic silver 5 (on the cpu)
4. I applied the hyper 212 evo to the cpu, pressing firmly, and tightened all 4 screws with the criss-cross method.
Note:
I did notice that the heatsink did actually slide a bit while I was screwing it in, forcing me to slide it back to the CPU center. Could this have something to do with it? I'm going to re-apply next week and post the findings.
thanks.

I'm not too sure, but it very well could be. I know it can be hard to line up the heat sinc, drop it in place and screw it in (or whatever each model does to hold it on). I have yet to master that myself...

As far as the overclock at that temp, I know IBs heat up a bit, even without voltage (and especially with it). Even so, I'd think at 4.2 Ghz, you shouldn't be having it this bad, especially with a solid sinc like the EVO. Just keep at it, I'm interrested to see how things go with all this, especially since I plan on buying the 3570k myself.

I suppose there is always the possibility that your chip was binned for this very issue, and that is why it's a 3570k and not a 3770k, but don't quote me on that. In that case, there would be nothing you could do. I don't think its super likely, but it's plausible. Either way, I wouldn't give up, there is still quite a bit of stuff you can try.

Good luck!

EDIT: I just reread your last post and saw that you undervolted. In that case, I'd say it HAS to be either the heat sinc seating, or the thermal past, because you shouldn't be getting this kind of heat. I'm confident you will solve it!

Amazing that no one even mentioned that:

1) Z77 Extreme4 isn't a great OC'ing motherboard, so don't expect too much from it.
2) But more importantly, HWmonitor is a really bad temp monitoring software as it usually gives really OFF values. Real temp and Core is recommended.

My hw monitor is spot on with real temp and core temp...

Why are you putting thermal paste on the heatsink and the processor?

and the slight jiggle could cause a air bubble=bad temps....

I have never used a hyper 212 or 612 or w/e it is biggrin.gif so im no expert on it
But im at 4.5 at 1.310 and my highest core is 62 and that's watercooled.
at stock or even undervolted it doesnt go past 40c

First off, don't worry about idle temps. There are too many factors that can affect idle temps - and ambient temps play a much bigger role. What are your load temps, and more importantly, what is your actual load Vcore (from CPU-z)? Just listing the offset doesn't help much, since VID will vary by processor. Aos, what speed is your heatsink fan running at?

I agree with what others have said, no need to apply paste to both the heatsink and CPU. It sounds like you have way too much on there. Just a small dot, around the size of a rice grain, in the center of the CPU is required. Allow the mounting pressure to spread it.

Also, while a LIFTING heatsink during application is bad, to have it sliding around is actually a good thing. I always wiggle and slide my HS a little when applying it as it will help spread out the paste. Just note that so long as you do not lift it you will not have much in the way of air bubbles.

And, as others have said, use the latest versions of Realtemp or Coretemp to read the core temperatures.

1. Plenty of people get decent OC with the z77 Extreme4. This is silliness.
2. I use HWMon and Realtemp. Both report the exact same numbers.

1. I put thermal paste on both because the Arctic Silver 5 directions for the 3570k call for it. If you go to their site and use the instructions page, you will see that they talk about "tinting" the heatsink, which shortens the break-in period. You basically rub thermal paste into the heatsink, then wipe all of the excess surface paste off with a coffee filter, only leaving the microscopic amount in the pores of the heatsink. Not sure if this is a good idea though, arctic silver might be just trying to have users use more paste.

2. When my CPU was completely stock with no changes, I was getting 27C idle and around 50c under full load. When I overclocked it using the guide that I mentioned in the first post, I immediately started getting the high temps. Right now I'm at 4.2 ghz (42 multiplier), Load line set to "3", and a -0.040 undervolt with all other settings to "auto" - my idle temps are as mentioned, but average 35c idle after overnight shut-down, and top out under a full load of gaming at 66c. Prime95 load is around 80c.

1. Load temps max out (while gaming) at 66c right now. Under prime95 custom settings it's closer to 80c after 4-5 minutes.

2. Idle Core Voltage, as reported by CPU-Z, with 5% load, fluctuates between 0.904-0.968 volts. With 100% load from AIDA64Extreme, CPU-Z reports CPU Voltage to be between 1.176 - 1.184 volts.

3. CPU fan, as reported by BIOS and HWMon is approx 1,885 RPM (always at 100%).

It's still decent , i have worse board (Asrock Pro4-M) and still achieved 5,2 ghz validation , 4,6 ghz prime-stable-12+h on EVO 212.

Based on what you have said so far I would suggest the following:

1. You should stop using the AS5 as per instructions, you are likely using far too much. People around here have tried and tested over and over and found that the center dot or extremely thin line methods are most effective.

2. You could get a better paste period. AS5 is very old by modern standards and not particularly effective compared to the more modern pastes. These can net you up to around 5c compared to AS5 these days.

3. You may just have a 3570K with particularly poor TIM underneath the IHS. In this case, your only option would be delidding. This option is not for everyone, but when done properly will knock 25c off almost any Ivy Bridge CPU.

3) Deliding - 25c off if TIM like coollaboratory liquid pro with high thermal conductivity is used on die, others might offer small improvements , but still noticable ones.
