Core Temps Go Up Very Fast

[selectodude]

Basically my problem is that I just got a new motherboard (ASUS P5WD2 Premium) and I installed the processor, installed Windows, ect, ect. I installed ASUS PC Probe II and it shows my temp at 46C. I started Orthos just to see my max temp under load, and after 2 or 3 seconds it'll jump all the way to 55C+, leave it for a minute and I'm at 75C and the system shuts down. I have reinstalled the heatsink and thermal paste twice and that hasn't seemed to fix things. I have not a clue what I should do.

Thanks in advance for your help.

Wow, somethings not right here. What are your readings in CORETEMP? If the PC shuts down due to your CPU being extremely hot, then I find it hard to believe that your CPU is making contact with the H/S. What thermal paste are you using? What H/S are you using? If your using the stock cooler, or an aftermarket cooler that using the same 'Intel Style" hold down black plastic push pins, then it is very common for them to pop out. sometimes you have to twist the black pin around, and you will hear it CLICK. Good luck, but if you still can't get temps down, read my SIG :-)

This is a CPU/HSF combo I have used in the past with impeccable results, so that can't be the issue.

I'm using an Intel Pentium 4 561 ES with a Zalman CNPS9500 and Arctic Silver 5 Ceramique.

I'm going to clean the processor and HSF *again* with 95 percent isopropyl and clean some of this phase goop off. Hopefully that helps.

The reason I dont think it is making solid contact is because you say the temps keep climbing up and up till the PC shuts off. If your cooler was making decent contact, it would at least stop at a certain temp and hover around that temp. OR, what is your Vcore set at in the BIOS? Maybe if it is set to AUTO, the board could be OVERVOLTING it to extreme V's.....

if you believe that running orthos isnt going to cook your cpu then you need to back off and think about what your doing.
orthos is a cpu cooker and it will, WILL make your cpu run extremely hot.

that cpu is a hot running cpu already and when you use a less then spectacular heatsink like the 9500 with really crappy thermal paste like ceramique, your gunna get ugly results.

i may be totally wrong here but a 561 is 115-120w cpu i believe ? maybe slightly less, that means your temps right off the bat are gunna be hot.

that heatsink doesnt handle high wattage cpu's very well, and its why you dont see poeple overclocking on air with that cpu very much.

for you to be running 70c on air with that cpu and sink is not surprising at all.

but very well could be the fault of several things.

1)
heatsink not making proper contact, this is the fault of improper installation and you need to triple check things
2)
misreading of the mobo
3)
the top of the cpu IHS is concave and you will need to sand it down flat but using some 800-1000 grit sandpaper on a piece of glass so its perfectly flat and sand it down and keep sanding until all you see is a nice clean copper surface. you will see as you sand it where the low spot is as the surrounding are will show copper but the low spots will still be silver color.
dont worry about polishing it as that has absolutely no bearing on temps, people do that cuz they think its cool to do but it has absolutely zero effect on temps. infact anything over 800 grit isnt going to change temps. although i use 1000 to finely sand it one last time.

auto vcore will not overvolt the cpu infact auto is nothing more than stock or slightly over stock it doesnt raise the vcore as you overclock.
and auto will give it the right voltage for what the cpu is asking for.

i went thru 3 p5wd2-e prem. and never got a good one, they all had massive droop so overvolting ? no infact just the opposite.
they do not overvolt on auto either...
but use the monitoring program or something like speedfan to check your voltages

Like I've already explained, I *have* used this CPU/HSF combo and it has worked very well. What your saying has no bearing on me because I know that it's wrong. This processor and this motherboard should be stable at stock voltage and speed without a problem, but it's not.

I've set the vCore under 1.4V (there's a vDroop mod on this board) and I still have temp issues. Also, Ceramique isn't "really crappy" and I don't like you trashing my components like that. I'm not an idiot and I know what I bought.

Thank you.

Have you got any idea's what your temps were like before, I never had these prescot cpu's so I'm not aware what is good or not...
Maybe the fan is dying on the Zalman, can you read out the rpm in ths bios, maybe it's throttled by those Asus Qfan or whatever they call it... did you alter eg the bios lately or so , maybe there's a bug in the autoprottect area ?
Also is the Zalman base warm indicating good conduction...

Don't attack Lestat, his comments are always scary , that's why he uses the shark in his avatar, he bites but only feeds on little fish ...

welll hello Mr. Fancy Pants
alright since you already know that you're right and im wrong you can figure the issue out on your own
reread my last post i told you what the only possible issues are, heatsink, cpu ihs or mobo reading wrong.
or
its sucking in a buttload of heat from other components and making the cpu run to hot.

but because i wanna help ,, here is one last crack at it.
here is some basic computer knowledge,
take your hand and grab the heatsink,,, is it hot or warm or cool?
is the air coming out of the heatsink warm or cool?

i'll let you use common sense to figure the rest out.

*hint* if the air aint hot shut off the shut down temperature feature.
or rma the board its got a bad onboard probe

"Arctic Silver 5 Ceramique"

which is it,, Silver or Ceramique.... they are two very different things....
silver is,, well silver and ceramique is white.

one is called AS5 the other is called Arctic Silver Ceramique, notice the lack of the #5

just need to clarify that as they are different.

My temps before were an idle temp of around 48C with the fan at the lowest setting. Now, they're 44 with the highest setting, which is about in line with before. Load was around 59 or 60 (lowest fan setting).

Maybe the fan is dying on the Zalman, can you read out the rpm in ths bios, maybe it's throttled by those Asus Qfan or whatever they call it... did you alter eg the bios lately or so , maybe there's a bug in the autoprottect area ?

The fan looks good, and the speed is independant of the motherboard. I can set it myself. All I can think of at this point is a wacked sensor.

I'm a bitter person by nature, but I don't go out of my way to attack and demean people because they have a question.

Well, it seems that one of the pots was set to add +0.1v to the vCore. I was running too much voltage though the CPU and once I fixed it the temps dropped several degrees almost instantly. Thank you all for your help.

Now...to start overclocking again...

[Leeghoofd]

well okay glad you found the culprit but 0.1 volts ain't gonna make that much difference, or was it more in total ?

That's one hot CPU , one of the reasons I chose AMD at that time over Intel...

[ziddey]

do you by any chance have peci (if you ahve that option in your board) on? if it's on, try turning if off. like mentioned, 0.1v shouldn't make that much of a difference, especially with that heatsink.

I don't know what it was, but 1.45v and the heat is under control. 1.53 and the heat kills the computer. *shrug*

peci? Do you mind elaborating on what that is? Thanks.

Well damn man, of course 1.53v is gonna be hot, especially on a hot CPU like yours. No wonder you were having heat problems. Unlike what Leeghoofd said, 0.1v can make a big difference in temps.

[ziddey]

lol 1.53 on a prescott. nevermind i take back my comments about it not making a difference ;). yeah it would :P

peci as i understand it is having the bios use coretemps. i understand the p4's didn't support it, and while your cpu is es, it may not have a disabling bit for it or something, so the motherboard may be freaking out if it's turned on.

chances are though that's completely irrelevant though since it's under control now

[Leeghoofd]

That's what I meant by upping 0.1 on top of stock Vcore or on top of his current setting. I thought prescots were around 1.3-1.35 margin , if you up to 1.53 you are already talking over 0.23 that can add indeed some heat...

I doubt that's even supported on my motherboard because it predates all thinking of Core 2.

Anyway, I guess this is just a hotter chip then normal, as I can't get it over 4.22GHz without it spitting heat-releated errors in my face.

Thanks again everyone for your help.
