Hyper 212 Evo odd temps

[RE-EM]

Hi

I just started overclocking my 2600k with my newly installed Hyper 212 Evo. I barely manage to get stable at 4.2ghz and I already have run into many problems. Well the most serious at this moment is my temps with this new aftermarket cooler. Currently I am stable at 4.2ghz with vcore set to 1.33 in BIOS. Now when I run Intel burn test at maximum stress level cpu-z shows 1.24 vcore after vdroop the temps get as high as 63C, 70C,74C,71C. I have already tried re-applying the thermal compound that came with the cooler using the line method. Then I also made sure I covered the very tiny gaps between the heat pipes. And last but not least I mounted another 2nd fan (gentle typhoon 1450RPM) in push-pull configuration. So my questions are:

1. Why am I getting high temps? I read other people get max 60C at 4.5 ghz and 1. 35vcore with this cooler.
2. What's up with odd core temp that is 10C cooler than others?




Could I have applied to much thermal grease? Though I'm not aware of how much is too much.

Thanks in advance!

What are your ambien room temps? Also take in consideration that HT is enabled and will result in increased heat generation under load.

My room is at 18 C

Additional Comment:

I recently remounted the heatsink and reapplied the thermal paste , still the same temps


Before



After

On the after are you putting two different paste ?

I would just put some only on the cpu that looks like to much your using

[pckid9234]

Way way too much i think. Small pea size and and let the HSF spread it or use a CC

[RE-EM]

Ok , so I should remove the paste on the heatsink and apply even less than it is now applied on the cpu?

[mimart7]

Remove all the paste, and use much less. You can use isopropyl alcohol, 90% is best. The amount you're using is acting like isolation.

Fixed it for you

If the evo has grooves between the pipes try filling them all with paste and level it flat to the base with a razor blade or credit card. I have an xigmatek dark knight with the direct touch heat pipes, i had to fill the cracks then put a little bit on the pipes to get the best temps.

[Nagoshi]

Just fill the gaps on the cooler's heatsinks, then scrape the rest on the heatpipes using a credit card. Then do a line (or an X) on the CPU (total equivalent of a small pea), perpendicular to the heatpipes, then install the heatsink and wiggle it to spread it.

Thats too much paste.

Wow, just a couple of min ago reapplied newly bought Arctic Silver 5 , and the load temps went from 67 to as high as 80C. And heres how much I applied.

[SlaveOnDope]

Got to fill the heatpipe gapes as Nagoshi said. More paste.

[RE-EM]

Ok its getting pretty annoying, I reapplied the paste again only on the heatsink, getting the same temps up to 80C
I guess Arctic Silver 5 is a VERY crappy thermal paste. What is wrong with it?
Cooler Master could keep my cpu at max 67C.

I mounted another 2nd fan (gentle typhoon 1450RPM)

Does this fan move the same CFM as the other? Match the fans and get high CFM fans and don't use the Cpu plug on the board. Run them full blast if your overclocking. Never take chances.

Case fan configuration also can be questioned. You said 18c in the room? That's 64df. Your temps should be much lower. What case? How many fans? which way do they flow? What CFMs?

2 words for Sandy Bridge. Liquid Cooling.

Arctic Silver 5 is not a crappy paste. Something's wrong or you're doing something wrong at this point. Try a small 'X' on the CPU, then while putting pressure on the heatsink, turn it back and forth to make sure it's fully spread.

If that doesn't work, try another cooler, the stock cooler if you still have it and report back with the temperatures.

Update, I removed the heatsink to check out whats the problem with high temps, and I discovered something nasty. The reason why Im not getting lower temps is that the heatsink doesn't touch the center of the cpu. Check attachments

So I reapplied and put more paste and now my temps dropped to almost where I previously was, now instead of 67C at 4.0 ghz I reach 70C at 4.0ghz, so there you go the 2-3 difference between the thermal compounds. So now that we know whats the problem, how do I fix it? Its still too hot for a 4ghz overclock. Btw I also tightened the screws on the bracket and back plate tighter till I couldn't turn anymore. Its pretty much as thigh as it can get. Oh I also use 99.7% alcohol to thoroughly clean everything that has touched the paste.

Huh... take your razor blade and put it on top of the heat sink... See if its flat.... If its not rma? Jus throwin ideas out

[Namtaro]

Not sure if they do that anymore, but I remember that the CPU metal blocks were always 'bowled' out. Kind of like a convex shape. CPU heatsink manufactures made their heatsinks concave to compensate. People used to 'lap' their heatsinks and CPU's to flatten them out, but that voids the warranty.

Like pckid said, get a razor and check it against the heatsink and CPU to see of they're both flat. Hopefully it'll be the heatsink that's not flat.

Have you tried using the Stock CPU heatsink yet?

[Mr.Scott]

See this nut? (see pic)
Tighten this until it stops. It's puts greater pressure on the center of the CPU.
