today purchased asus p8h67m evo
motherboard and core i7 2600.
amd 6870hd,4gb ram,2tb hard disk.
my motherboard shows cpu
temperature warning what is the
problem.it's temperature shows 97c.

Stock HSF ?

Sounds like it is not installed correctly ..


Google " 2600 install HSF " ... Should get info and videos of what to do .. Plus, you might double check the instructions that came with the CPU ...

All four corners must be flush with the motherboard..

It totally sounds as if the CPU heatsink/fan is not properly affixed. Which heatsink are you using with it?

stock hsf

I just try to shake it but it is tight and doesn't shake.i also wanna told before 1 week I installed it on asus h67m-lx but then my temperature was just 65c after high gaming etc what is the problem now.

just tell me if hsf is not shake,is there any chance that it is not seated properly,if yes then reply I can reseated it

See if the fan on the heatsink is still spinning.

Try reinstalling the heatsink.

just remove heatsink and thermal paste and set again now temp shows 78c and after installing windows 7 and asus utility it shows 48c. what is correct information?

here are the numbers of real temp and core temp.

but in the asus bios its shows 87c and after every 10 seconds its give me warning by giving sounds

There is a sensor at the center of the CPU, and there a sensor on each core. Based upon your case, it seems that the sensor at the center of the CPU is broken(reading wrong values). Bring the chip back to where you brought it from and ask them to diagnose it for you. It should take 1 min for them to say, "Damn, ain't you lucky?" and replace it for you.

if this is true then how can core and real temp software can detect the right temperature of the cpu because they also take the reading from there. I think it is just bios software problem but it is the latest bios in market.

First, you are reading number off different sensors. There is a sensor located at the center (geometric center) of the Integrated heat sink. The thermal reading off that particular sensor is called Tcase. The thermal readings you get off each individual core are called Tjunction. Usually, The difference between Tcase and Tjunction should be very close unless it is under load, which will then be about 15 degree apart(the difference is called delta between Tcase and Tjunction). Tcase usually has lower readings then Tjunction as Tjunction is closer to the source of heat. BIOS reads off TCase, while the numbers you have shown are all TJunction. Dig into those settings to show TCase. There are no offset you can play with in BIOS on TCase. If it is a firmware problem, then you won't be the first person who run into this.

Cut those crap and back to your problem. It appears the Tcase of your CPU is too high while Tjunction reminds low. This is not usual because the temp off the source of heat can not be lower than reading off the geometric center of the IHS. While Zap's point is still valid as if the center of the IHS isn't touching the HS, it is possible for it to have a higher reading. If the IHS or HS both concaved in then it is possible. That is what thermal paste is for.

People even say too much thermal is bad, but what they really mean is the performance of thermal conductivity of the paste decreases if you put too much, but how much is too much? If the 2 surface are flat, then a grain of rice worth of thermal is enough, but that requires the assembler put the pasting at the center of the ISH and spread those pasting evenly by turning the HS on top of IHS slightly, about 5-10 degree in both directions until it the pasting is spread out evenly before locking the HS in place. If the assembler move the HS in a circler motion instead of rotating the HS and the surfaces are concaved in, then there is a small chance that this will happen. I say you have a defective CPU where the TCase sensor isn't working properly.

Edit: for the fun of it, you can see if the surface is flat by placing a blade on top of it (blade that is used it cutters.)

just got reply from asus for this problem and they just say that......
Dear Sir, The performance of new sandy bridge CPU is very high. It will produce huge heat while booting the system . So you find the CPU got high temperature in BIOS. And these CPU also equipped with the feature of energy conservation, such EIST (Enhanced Intel SpeedStep® Technology) But these kind of feature will effect only under os.When the feature is working, the CPU temperature down with the CPU performance down, So you have found the CPU temperature decreases under OS.
This phenomena is normal.

i've similar problem myself, the 2500k goes for upward of 95 degree Celcius while running prime 95 for about half hour, now i'm waiting on few heatsink i ordered to tried it out. my temps are totally worst compare to others, but i do believe the H60 is bad egg from corsair's basket as there isn't a room left on it for error and my temperatures are pretty close to stock HSF. waiting on H50 brackets and if works out i'll just send the H60 back.

Tell them they are full of crap. 80 degree right after post is not normal. I use SB 2600k with a weak fan on H50 and bios reads 40 degree while the pump is running at 60% (that is why I go into bios to set it up to 100%), while older gen CPU doesn't break 35. Granted there are still things I can do to fix the temp, 80 degree is not normal.

Having said that, I got my temp right after installation, but after window 7 installation, plus my Tjunction reading is at 40 post window boot and my room temp is 30 degree.

Let me ask you a few questions:
What is your Room temp?
What thermal pasting did you use?
What heatsink do you use?
Does it cause auto shut down due to overheat?
Did you tried to stress the system with programs like prime95? If you haven't because you don't feel save, just state it, I understand.
Did you purchase your CPU online? Say if you brought it through TigerDirect, You should be able to bring it to the local TigerDirect store for diagnostic.
Have you tried programs like "Real Temp" to check TCase temp in windows?
How did you apply? describe the amount and method used.

Sorry for the long list, but with those information more people will jump in and share their expertises on this.

I don't know my room temp,but I can tell another information like I use a stock heat sink that came with core i7, no I don't use prime 95 and i m just doing gaming and some photo editing,i use normal white colour thermal paste, and my pc doesn't shutdown automatically but it gives sound weirdly in every 5 minutes and I also use real temp it shows cpu temp is 45c but in asus bios i see 97c. and I purchase it from a local store.

I too have been plagued by high temps and not sure why. I now have my 2500k clocked at 4.2ghz with 1.24 v-core and still get load temps while gaming in the mid-70's. I switched from a Zalman Performa to a dual fan Noctua but didn't really see a difference in load temps. Idle temps are great, but load temps are high. I am almost certain I applied the right amount of thermal paste and seated the HSF correctly.

More of a curiosity for me, though. I am not losing sleep about it because I don't put it under load stress often and usually replace the CPU with a new build every other generation.

If you brought it at a local store, than you have omitted a lot of trouble. All you have to do is to bring the whole computer back to them diagnose it for you. Keep the "it was working fine" part and the BS from asus rep out, just say that it beeps since day one and bios read over 80c.

Look, if it is user error, then you may look dump in front of the technician, but that is what s/he is paid for and at the end you will have a working computer. If you want a working computer with the less amount of work, then simply bring it back to the shop and have them look into it. Whenever customer (you) claims the malfunction is due to defective (broken) parts, those technicians will need to first verify if parts are indeed defective. If it is indeed defective, they will exchange it or give you refund. If it is not defective, then you walk/drive home with a working computer.
