I5-4670k maybe mad or improper thermal paste?

[negru08]

I have a Asus Maximus VI Hero motherboard with a 4670k CPU. I dont know if I have a bad CPU or bad thermal paste spread or ??

First off I can not get it to be stable at 4.5 Ghz unless I use a 1.335 volt and that scares me. Do these new chips handle higher volts without degrading or did I get a low end chip?Anyway I backed down to 4.4ghz at 1.285. Seems to be stable even though I feel for 4.4ghz that is high. But ran Aida64 stability test for 8+ hours and no issues.

But my max temp got to 83c but averages where around 64c. IS that good or bad? Also for some reason Core1 was about 12c hotter then core 4.

Core1 usually ran about 77
Core2 usually ran about 76-75
Core3 usually ran about 73-72
Core4 usually ran about 70-68 and maxed out at 73 while the rest hit 83-80 as max

Does that mean that my heatsink isnt on properly or I didn't apply the thermal paste correctly? I have a Noctua NH-D14 cooler.

Those temps look high!

I suspect the CPU/heatsink installation. Apply a very thin and even layer of Arctic Silver 5 and re-do the install.

Those temps are high? Where do you get that from? Everywhere I read for a 4670 anything under 85-90c I read is acceptable. I did that. I applied a pea size in the middle and put the heatsink on and let it spread. I am starting to think to many people are comparing haswell to Ivy bridge temps. Sure I was able to get my 3570k at 4.5 and only run temps into the 60C while stress at 100 but this is Haswell and its a heating bitch.

Honestly if those temps are to high then by your standards i can only OC to 4ghz at 1.125v which is the only way I can get 60C on Aida64 stability test.

However, if you feel your temps are fine then you do not have a problem!

He has a water cooler....and a 4770k which over clocks naturally better than 4670k. There is no comparison to that which is why I dont know. I have a air cooler NH-D14 Air , not any liquid.

I can give you some info for comparison; not a direct comparison, but a comparison anyway.

I have Ivy Bridge (i7 3770K) and I am aware that you have Haswell. On my i7 3770K I get 4.6 GHz at 1.275V and the idle temps are around 33 degrees C. Gaming temps are below 60 degrees C and prime95 is below 70 degrees C.

My heatsink is a Cooler Master Hyper 212 EVO. I polished (lapping is not possible manually by any human being) the base and made it flatter, used Arctic Silver 5.

I am also aware that some CPUs will overclock better than others with identical specs because of the die location on the wafer.

Hope this helps!

Those temps seem right in line with the voltage..
Those chips vary greatly on getting hot/voltage necessary for X clock.
IMHO that's right on par for 4.5 haswell temps
As for me..I'm a little OCD about not going over the 72c ..
so I'd go with 4.3-4 and as little voltage as possible.
I had a pretty good chip..got it to 4.7Ghz with 86c max temps..(for a daily config)
The temps just make me woozy though.

So then I guess my main question is what are safe voltages and heats for the cpus. Read that max on air for volts should never go past 1.4v but I just find that crazy. Makes me feel like it would make the cpu die in a day. Also read that 80-90c under 100 load is acceptable. I dont think I explained correctly. Those were my max temps . I watched it for an hour and while testing in Aida64. It ran around 75c , every now and then hit those high temps but only for seconds.
