OC Core temps on i5 3570K

Last response: in CPUs

Why is my core 0 (1?) temp 10C less than cores 2/3 (3/4?) in and about 6C less than core 1(2?). Normally a 7/8C difference between core 0 and core 2/3 core 1 being in between the two.

Also i was running prime 95 and my max temp per core is as follows.

72/80/85/80 but only for a few seconds and then when i reset my max it is now
66/72/73/72 Max Celsius. Is this because the fan kicked in a higher RPM? I'm using a decent cooler

Zalman CNPS9700 LED with arctic silver 3

is my thermal paste bad / not spread even / something like that?

What is recommended volts for this processor and recommended max temp? im going to look for a way to run fan at 100% no matter what. so should i disregard that max temp if i haven't hit it since the temps dropped
active temps are like
64/69/68/68

im at..

4400 MHZ (sometimes it says 4399.53MHz or some odd number like 4402 in CPU-Z)

VID in core temp says 1.2910 v sometimes 1.2860 v

and in CPU-Z the "core voltage" = 1.264 V - 1.272V - even 1.2564 V (is that my PSU feeding my unsteady volts? *i can post my PSU just gotta look at what one i got i forget offhand.

sorry a lot of information .. hope its not a hassle to help me.

Thanks a lot, much appreciated!!

Try reinstallting thermal paste.

OK, is there a way to get it off safely? The CPU Fan / Heat-sink. Last time i bent a pin (though it was on a Pentium 4 which had the pins on the processor. The processor i have now the pins are on the motherboard. And the way it locks in is new so it makes me think it will be safer.

also i have a cleaning solution that i will use, but to not scratch the plate what is best to wipe it with? paper towel? rag? microfiber cloth?

And when putting on more thermal paste what way is now recommended? A glob and press hard (this CPU cooler puts massive pressure on the CPU when installing it.. like scary amount when i did it the first time (i really dread taking it off))

Or should i use a card and do it manually (spread it)

Should i look on the cooler manual?

is 90degress hot for doing intel burn test
85 max on prime95 and

88 max on linx

i should mention, my idle temps feel lower than what i have seen posted around.

24 26 28 26 C (core 0-3)

* Take off cooler and clean the thermal with alcohol and use X method:



* Reset your BIOS to default, start OC again.

For cleaning: rubbing alchohol and a lint free/microfiber cloth. If there is a lot you can use a paper towel for a first pass to get the bulk of it.

For applying, if you have a high pressure mount, use as little compound as necessary. A "grain of rice" sized bead should do.

Burn in time varies by thermal compound, but 24-48 hours of use should be good. You're not doing too bad if it is running stable at 4.4ghz.

*dumb question* only do the red part? lol .. not the green part too right? (on the guide it says to do a straight line down the middle (for i5 processors not for my cooler that is heavy pressure.) and the x sounds better IMO but i dont know much.

and thanks for the replies.

yeah its stable, but not in intel burn test :(  .. tho i lowerd the volts before i downloaded t he intel test so if i bump them back up a notch maybe it will be ok

i mean it ran and passed, but when i set to Maximum it crapped out, fairly quicliy i might add.. though i was doing homework, had 25 tabs open and 5 temp reading programs.. so this time when i set the thing to max ill close all programs out to free up some memory!

A little slug in the middle will do the trick. You'll end up with too much paste if you try to do an "X"

thanks lowguppy i agree i think that i will be best to do a line. appreciate the help!

what do you think of it failing after a few mins on MAXIMUM (i dont see how letting it use all my ram is causing my cpu to fail) but im a little new to this

The X is the thermal that you gonna place, The Green will be the distribution space (leave it)

FYI, The best method is "X", second "l" method.. see this vid http://www.youtube.com/watch?v=-hNgFNH7zhQ

what thermal paste should i get. mx-4 or mx-2? i liked artic silver but i think mine is too old and stored on its side not tip down and may not be mixed well anymore.

and i want to buy something with a smaller break in time. like 300hrs + for arctic silver? thats a little much. unless i can overclock normally in this break in period. whats your thoughts

http://www.newegg.com/Product/Product.aspx?Item=N82E168...

there 25% off next few days

or should i go with arctic silver .. or something else that i haven't heard of?

like i stated earlier i have a Zalman CNPS9700 LED cpu cooler .. it is a huge heat sink that has high pressure mount

not sure if that makes a difference.

Go With Arctic Silver!It's far better that the other two!

Arctic Silver has an age old reputation but the best thermal compound is currently Gelid GC Extreme.

Check out this very comprehensive review:

GC Extreme is even on sale over at newegg http://www.newegg.com/Product/Product.aspx?Item=N82E168...

cool, sound advice haha thanks, def agree with that guide (tho some on that list are better? but i don't like the term liquid makes it seem less pasty.)
