I've just built two new rigs, both are identical. Everything at stock settings (3.5Ghz + 3.9Ghz Turbo) is showing 28c-40c idle and around 75c-80c on load. One the other rig it's around 66-70c on load.

I've tried a pea blob TIM, using an old card to make it paper thin, I've tried removing it all and reattaching it but no matter what I do it's always around 77c average on Prime95 after 10 mins or so.

What is going on?

I'm using a Corsair 550D case and MX-4 TIM.

The grooves between pipes are not really worth worrying about since very little heat will make it that deep through the TIM anyhow. The TIM is there to fill the ~50 micron tolerance between mating surfaces, not ~1mm deep gaps. Once the gap thickness gets greater than that, filling with TIM becomes exponentially less effective due to rapidly diminishing temperature difference (heat transfer rate scales exponentially with temperature difference) and the TIM's much higher thermal resistance than copper/aluminum.

Filling the grooves does not hurt but is not worth obsessing over as the extra contribution is negligible.

buddy listen to me, the cooler master 212 cpu cooler SUCKS its not good. i7s and fx8350s are a beast on heat... dont listen to what everyone says that the 212 is an excellant cpu cooler becauseits not... its just good for the price but its not any good. you will need atleast a noctua nh d14 cpu air fan, or a corsair h80 for that cpu. take my words as facts

you dont know the difference between cpus and heat...???????????
the fx8350 will burn up with the 212 cm cooler. but the fx 4300 will not
an i3 and maybe even an i5 will do fine with the cm 212, but the i7s wont
learn about heat and take my words. inveast in a d14 for the 3770k atleast

yes ill tell you the golden answer. cm 212 is only for low end cpus, there still a 30 dollar cpu fan and u will not go far with that. for the 3770k , an fx8350 even an i5 3570k you need a way better cpu cooler then the 212. noctua nh d14, phanteks, the high end cpu fans and liquid coolers are meant for this option. so you need to buy a new cpu fan

Are you plain mad?So basicaly a stock cooler will have like 100ºC according to your logic.
Look at the idle temps!They are high meaning something is wrong.

What is your room temperature?Do you have good air flow in the case?
Maybe you applied insufficient thermal paste or the Evo is not seating right.
Do temps vary very quick i.e. going from 40 to 50ºC in a sec?If so the evo is not being able to draw heat from the CPU which points to bad air flow,too much/too little thermal paste or the evo is not making good contact with the cpu.

And those options are not meant for stock cpus,they are meant for OCing.
To run at stock you can use the intel heatsink safely.

dont listen to this guy, your idle temps are actually ok at 40c a little high but once you stress that beast of a cpu you have it takes alot to cool it, this guy does not have an 3770k like me so he really doesnt know that the HT produces alot of heat. ur getting to the 70 80c which is high. theres nothing wrong thats normal for the cm 212 its not a good cpu fan for the i7. the stock cooler is a joke for both intel and amd products. you can try re applying thermal gel and differnt types of thermal gel but ur not going to see a difference. new cpu fan is the key

Just /facepalm really.I guess the other i7 users on stock and evos HSF are all wrong.

You got a good method to see if the problem is bad air flow:just open the case and point a summer fan(those big fans yes) to it,if the temps drop more than 10ºC then you have poor case air flow.

sounds like u dont like the truth from someone who may come off arrogant, wellllll its all about the truth and ur not helping this guy out. welcome to the year 2013 where companys cheap out like crazy. i have 2 rigs. my fx8350 stock cooler was hilarious. at stock settings with the 8350 i was getting to the 90C range. companies allow this for stock coolers because they go by actual use and not stress testing. dont get mad because someone on Toms sounds like a bully u dealt with in highschool. i guarentee he already has the side panels off whenhes stress testing and puting his i7 on full load... and guess what? still 80c on teh cpu.. why? not a good enough heatsink. anything can make sense if the sky is green in ur world lol

Didnt even bothered eading everything,stopped at arrogant.
Google i7-3770k + evo 212 and see people reaching 4.2-4.4ghz with it.Problem is auto voltage being too high or not enough air.
You wanna give advice,google it first,don't assume something as a fact just because it happend to you.

The hyper 212 evo is capable of cooling your average i7 3770k and as to the temperature differences it could be possible that one of your chips is bad and happens to heat up more due to bad thermal paste on the IHS or other problems.

if you want to reply to someone properly read what they say, this is not a jerry springer show.
google the 212 with the 377ok and youll see the results yourself. when u run a stability test, all 8 threads are being tested not just 4 30 dollars wont cut it for a cpu fan for the i7. there should be a temporary ban for guys like this, hahaha

Definately agree with you on the ban for you.Stubborn people giving poor advice like you should be removed from the forum.
Guess you name stays true to your character,being a Diablo fan you must spend hours on the D3 forums just ranting at everyone which doesnt agree with you.
Is your google broken or something?Because all I got is tom's forum post about the i7-3770k and evo 212 with good temps OCed
and other with solutions to this same problem.

Enough of talking to you though.Bye.

OP,did you try any of the suggestions?

Read this thread OP:

http://www.tomshardware.co.uk/forum/342076-10-3770k-realtemp-temperatures

This guy had the same problem as you,although not as severe.The difference is that he was using 2 fans on his evo212.
The problem was that the evo 212 wasnt sitting right or he applied too much thermal paste.
Try reinstalling everything and use a second fan on the cooler for better results.
More case fans to deliver cooler air is also a good idea.

the d14 is a cpu fan, thats why it has fans on it and not just a heatsink. but that was good for a laugh lmao made my day

If you don't have anything to help the OP and you're only here to turn other people's ideas down please go away.
The D14 being a "cpu fan" is laughable!Without the heatsink the fans would do nothing,on the other end passive HS with no fans exist and are used.I never heard of just a fan cooling of the cpu but maybe you did.
The terms cpu Heatsink,cpu cooler or simply HS/HSF are used,"cpu fan" is not.
But as I said your name says it all,you just want attention and replies to feed your trolling appetite and I for one am done feeding it.Enjoy your overheating i7 diablo24life but let others not confortable with their temps find a solution here.
Done with you.

its funny your comments are so maticulous that theres no reason to even explain them... why you felt the need to leave a comment on this thread that d14 is actually a heatink is beyond me. looks like you should heed your own advice. you have 2 options call it a cpu fan or a cpu cooler. a big chunk of metal alone is a heatink. shouldnt be to hard to miss the fans that are on some of them... lmao keep up the good work bro

There are at least two things:
1- the surfaces may not be perfectly flat and by using a "paper thin" spread, the layer may be too thin to fill gaps or the gaps may be too wide to allow efficient heat transfer
2- luck of the draw, one of your CPUs may be at the top end of the bin while the other may be near the bottom so one is drawing more power than the other under otherwise practically identical circumstances
3- of course, there is the possibility of incorrect mounting but since you said you have had success installing a 212 before and are at least on your 2nd try on this build, I'm guessing you have messed around with it enough to count this one as already investigated

Lets keep the insults out of this please.

There has been a lot of discussion here that didn't really involve the OP much.

SlvrYeti, what motherboard? What case? What PSU? What ambient temps?

And what BIOS version on your MBs?

Using the blob method with a cooler that has exposed heatpipes has one potential problem. Air can, rarely, become trapped in the grooves as the TIM spreads out. I have seen this happen, once, and seen the method work fine many times.

To be safe, I recommend applying TIM to the cooler and scraping off the excess, so that the grooves are filled with no air pockets.... then using the blob method to install.
