2500k temps high at 4.3 with Hyper 212+

Hey guys. I'm a little confused. I have a 2500k with a Hyper 212+ on a P8P67 Pro. It is only a month old and has never been overclocked so I decided to use the 1 click optimal setting on the ASUS UEFI bios to auto overclock. Well I loaded up and checked CPU-ID and it showed a 4.362 with a 42 multiplier and a 103 bus. Voltages were around 1.325. 30c idle BUT I loaded up prime95 and within 10m one of my cores hit 81c. At stock speeds I don't break 59c so I know the cooler is working right. I could even hear it speeding up properly so I can verify it is working. I used AS5 and I applied it properly. I just don't understand how that slight of an overclock could spike temperatures THAT high. I see people pushing these things to 4.7 and 4.8 so whats the deal? Could it have something do with the auto overclock? Any help is greatly appreciated!

Temps will rise to a point then drop back when running P95. At stock speeds running P95 is the temp 59C? Explain.

Yes I realize this but they should not be even coming close to those temps from my research.

At stock speeds these are the maxes:

Core 0: 51c
Core 1: 54c
Core 2: 55c
Core 3: 59c

Core 2 is what hit 81c. The rest were around 75-76 at the time.

Stock idles range from 24-32 (my room temp varies a lot during winter)
OC idles are about the exact same but they skyrocket under load as I stated above.

It's weird that it is that high at those voltage and speed but just manually oc. You'll be able to get lower voltages at that speed and not change the bclk.

Don't do auto oc. Set it manually to whatever multiplier u need and adjust llc accordingly.

why are those temps so hard to believe? you buy a 30 dollar cooler and expect to have temps about the same as people with 100 dollar coolers....

but your temps are about what they should be at that voltage. at 1.336 and 4.5 im seeing about 65* but i have a nh-d14 which is about 10-15 degrees cooler then what you have. at those voltages you should be at 4.5-4.6 though.

btw are you sure your bclk isnt 103.8?

you can lower those temps by getting another fan for your cooler.

remember voltage make an overclock work and also creates the heat. your at the voltage of a 4.5-4.6 overclock so your not out of the ball park

I don't buy a $30 cooler and expect to have temps the same as people with $100 coolers. I buy a $30 cooler and expect to have temps same as people with $30 coolers...and mine were not. No one below 4.6ghz with a Hyper 212+ have I ever seen hit 81c.

But anyways, I got it straight now. The auto OC was doing weird things. Set voltage WAY too high, so I manually OCed to 4.2 with 1.18v and it stayed around 65-66. Thats proper temps. NOT 81c...

I expect to see 65C with a Hyper 212+

My Phanteks PH-TC14-PE keeps me @ 49 - 53C on Prime 95 @ 4.6Ghz 1.35v

I dont go past 76C @ 1.51v 5Ghz

Your NH-D14 isn't doing its job properly bro - And neither is his Hyper 212+

I reccomend re-application of thermal paste - make sure you clean the old stuff of with TIMClean Isopropyl Alcohol.

65-66 is way too high for 1.18v on a 212+

Most people run 4.5Ghz @ 1.25 - 1.35v with 212+ in the 65 - 70C region on max load with the 212+

As I said before, Look into re-applying your thermal paste. And beware, your temps will take a few weeks to drop to normal, AS5 has a 200 Hour Burn in time where temps will drop ~4C

Are they really THAT bad? I thought that this was about right? Other people pushing 4.4-4.5 with 1.25v+ were hitting high 60s, so I just thought logically that mine being slightly lower voltage would be just a tad lower than theirs?

Btw, it ran 59c stock under load.

Yeah thats way too high.

There are plenty of folk out there with the same setup getting the same temps (Below 70C anyway) as you with 1.35v OCs.

As I suggested, re-apply thermal paste. Also, get another fan for Push/Pull, it can reduce your temps by ~2C. Every little helps!

Ok well that leads me to me next question. What is the best way to apply the TIM? I read 10 different places that suggest 10 different things lol. I originally applied it the way arctic silver suggested with the TIM in a single line going down the CPU. Then I read other places that say to place a pea sized drop right in the center and other places that say to line the heatsink pipes of the 212.

Pea sized drop bang in the middleand push the CPU Cooler down on top - Screw it down fairly tightly but not too tight. Twist the cooler around a couple of times to spread the paste and then tighten as much as possible.

Ok and if this does not help would that possibly be a CPU problem or cooler problem?

Well I just assembled my new setup. Corsair carbide 500r case with stock fans. 2500k with hyper evo 212 cooler.

I run 4.4 GHZ at 1.35 atm. Im at 29C idle and max 61 in prime 95.


Edit: I could prob go lower vcore but i havent tried it too much yet.

Cooler, Motherboard or CPU.

Cooler issues are usually easy to spot - Residue on the underside - bits of foreign material - bent or broken fins etc etc.

Mobo/CPU issues are not as easy to spot - but rest assured if you're installing the cooler correctly and both surfaces are clean and nothing on the Cooler seems out of place or broken, it will be a mobo/CPU issue.

In this case the CPU could be either running way to hot for no discernable reason or the Mobo could be displaying false information and supplying the CPU with too much power.

Also, are you checking Vcore when its on load? I had an issue where mine would jump to 1.6v on load.

I have not checked it under load. What was the issue with yours doing that and what fixed it?

Messing around with the offset voltage and the LLC got it sorted for me.

Basically the combination of settings I had made the LLC jump the voltage up to 1.6v. I fixed it within the ASUS Software with a bit of tweaking, then went back to BIOS Overclocking.

I set LLC to lvl 3, and offset to -0.4

I get 1.290idle and under load I get 1.330 max using prime 95, peak at 60C with the evo 212 cooler.

So you can try something like that. Spread spectrum,stepping, c 1 3 6 off(all power save mode stuff)

I think you mean 0.040

0.4 would be undervolting it to hell xD

yes -0.040 some how mine runs 1.375 by defult, maybe its cause i first picked the auto oc to 4.4 the changed from there ? i dont know.

It's that high because you changed your llc. 1.33 is pretty high for 4.4ghz. There's really no reason to turn off power saving features unless you like more heat/power. Multi, vcore, llc is really all you have to change when using offset and not extreme ocing.

The 2 line method is recommended for the 212+. http://benchmarkreviews.com/index.php?option=com_conten...

Thanks for your suggestion.

Re did it all now I am at 1.1Vcore idle and 1.280 under prime 95 @ 4.5 GHZ. So far stable gonna see for the next hrs.


Edit CRASHED!:D 

changed offset to + 0.035 now. 1.290 using prime 95. Testing for stability again :)

Oh ya since this is also about cooling. I did the creditcard method, not sure if it is recommended or not. What i did was make a line of thermal paste on the cpu, then spread it using an old credit card in to a very thin layer covering all of it, was pretty easy.

28C idle and 58C max with evo 212 at 4.5GHZ, so think it worked pretty well.

maybe with an i5 but remember i have an i7 with hyperthreading with more voltage at the same clock speed cause of hyperthreading. i thought my temps might be a little high but im not going to get 55* at 4.5 let alone 4.6.

Just going to put my 2 cents here

I have 4.4 44x100 @ 1.25 volts(For a 2600k). I have to set that manually because my board wanted to push 1.37(but i think it is a cpu thing, some kind of dynamic vid) and the temperatures move fast. Dropped it down to 1.25(I also have LLC on to stop droop and keep it close to 1.25)

Either way, temperatures are down to 58-65ish depending on core under prime95

I do not have the same heatsink(CNSP 10X Flex), but I would guess you are not much hotter them that(I would guess tops would be 70).

I have a 212+ on my I7 920 system and it works very well for me.

Ok guys well I re-applied thermal paste properly and reseated the heatsink. Its now peaking at 59 under load in prime95. Is this more acceptable? Also, since this is new AS5 could I expect lower temps as it burns in?

you can get to 4.7ghz with barely even raising the voltage, i have a hyper 212+ and im runnning at around 56c, but i also have like 6 fans in my case. 1.3v+ is kinda crazy and is really hard on the chip

agreed. 1.35 volts is the recommended max voltage but its starting to work its way to 1.4 volts
