Ok well i reseeted the CPU and i also blew out the heat sink cause it had alot of dust in it. It seems to even be raising temp faster now. I guess that might be because i just now ran it for a little bit. I don't have any thermal paste, so i guess ill have to buy some.

Ok i got this one from new egg. It seems to have the highest ratings.

Anything else i can try in the mean time?

if the fan on the heatsink is making noises, speeding up/slowing down it's on it's way out and not moving the heat away from the heatsink so needs replacing, your case fans are not a concern, just the fan on the heatsink. you say you reseated the heatsink, what method did you use to apply the thermal paste and what did you use?

[terry1966]

cancel that order and get this instead if you can :- http://www.newegg.co...N82E16835186020
with ceramique thermal paste there's less chance of shorting out the cpu or motherboard.

[jeff matthews]

All i did was take off the heat sink, dusted it out. And re seeted the CPU again. Then clamped down the heat sink over the CPU casing. When i took out the CPU. I saw the thermal compound spread over both the CPU and the heat sink. I currently don't have any right now, so i guess ill have to buy some. Now your saying the fan is bad. Well its not erratically slowing down and speeding up. I just notice it makes very slight noises, almost hard to hear if your not listening closely. That might just be a case of the fan speeding up or slowing down based on the temps raising, but that doesn't necessarily mean the fan is going out. I know what you mean by when a fan goes out. It stops and slows down and its very noticeable. This isn't the case for this fan.

[jeff matthews]

how do i actually measure the fan speed for the CPU fan in the bios? Ok i actually put my ear next to the fans so can listen very closely. Those noises i was talking bout are the just fans speeding up and slowing down. All my fans are doing, there changing speeds. The temp in the bios is still reaching 95 with in minutes though. Also i dont know bout buying more hard ware untill i know for certain what the problem is. Isnt there a better way of testing to see if the fan it self is bad or the CPU is bad. I already spend alot money on p arts that weren't even the issue. So before i buy anything knew, i need to know for sure what is the cause of these shut downs. I did how ever buy some thermal paste cause it was only 9.99.

the fan on the heat sink should be connected to the motherboard cpu fan header/connection point then in the bios it will tell you how fast it's running, it should be running at a constant max speed when your cpu reaches about 60c this is not what your describing. your cpu temp should be reading about 30c when it's idling not getting anywhere near 100c, 100c temps at idle are what i'd expect to see when a cpu didn't even have a heatsink fitted, so either the fan is not doing it's job or the heatsink isn't fitted correctly, or maybe both. you decide.

[jeff matthews]

hmm, well i have it plugged in correctly im pretty sure. Its connected to the mobo, other wise it wouldn't even run. When i look under Bios all i see is "CPU TEMP limit of Highest" 50 and then "JCPU fan highest settting 100" Other then that, there is the temp gauge. I really don't know what im looking for in the bios to determine the fan speed, unless its the RPM. In any case yeah its reaching 90c on idle in the a matter of minutes. That is most certainly the cause of my shut downs. But how to fix the problem? Hopefully I can do it with out having to buy a new CPU or a heat sink. These parts are pretty knew, i don't see how they would be malfunctioning. In any case, like i said before i do not want to go out and buy a new fan, a new heat sink and a new CPU, unless i know for certain what the problem is.

there's NOTHING wrong with your cpu, so don't buy a new one. it's just the fan on the heatsink that's the problem in my opinion and the heatsink needs reseating properly with new thermal paste. the fan just unscrews from the heatsink, you don't need a new heatsink either. read the links already supplied about how to clean and reseat the heatsink ready for when the thermal paste arrives. yes rpm is the fan speed.

Hi Jeff,

1.
In a PM last night at 12:28, you wrote:

When i was in the bios, my CPU temp jumped from 54C to 94C in just a matter of 5 min and then the computer shut down

That is a "serious" observation, and is consistent with the previous concern stated by both Terry1966 and myself as possible cause of the shut-downs.

Today in Post #61 above you report that you "reseeted the CPU", and "also blew out the heat sink cause it has alot of dust in it"
Then you report that Temperatures are "raising temp faster now".
Not Good!

Though you do not say, you are apparently relying upon Thermal Interface Material (thermal paste, TIM) that was already in place and applied by the manufacturer of the HeatSink you purchased with your new components when building this machine.

Often, manufacturer supplied Thermal Interface Material is supplied as a thick patch or thick donut shape.
I imagine it is easier for the manufacturer to supply Thermal Interface Material (TIM) as a patch that is easily applied on the assembly line, but I am not convinced that it is an effective method. Unfortunately such application is often "thick" and "un-even", preventing good heat dispersion, in my opinion.
The problem becomes even worse if the owner/user (you) remove and replace to "re-seat" the heatsink.
Pockets (pillows) of air bubbles can be caused.
Air pillows actually "prevent" good heat transfer, and ironically serve to insulate the CPU, making it hotter.

Thermal Interface Material should be a relatively generous, but "thin" layer of TIM that is spread smooth and evenly across the surface of the CPU.
There must not be "any" foreign debris, and absolutely no missing spots that can form "air pillows".

If you are not able to accomplish application of TIM as described above, you should get help for a knowledgeable assistant or take it to a professional.

From your recent reports, I am concerned that the TIM is not applied properly and has in fact formed air pillows, causing the reported increased temperatures.

CPU temperature occurs "instantly" when power is turned on.
Instantly, means "within seconds" of power-on.

When temperatures reach the 90c-100c range you have reported, damage to the CPU could occur.

Recommendation:
Inspect HeatSink-CPU surfaces to assure that TIM is applied smoothly and evenly.
Inspect HeatSink placement and securing assembly (levers and attachments) to assure that HeatSink is properly seated.

** This machine "should not be operated at all" if temperatures are reaching those levels! **

If necessary, get professional assistance.

agree with doug, don't even start the pc until after you've re-fitted the heatsink with new thermal paste.

That is absolutly correct. The temps are reaching high lvls in a matter of min. It seems to get worse over the course of time, you scare me when you say this can cause internal damage to the CPU. So i am deffinitly leaving the computer off for now. At least untill i can fix the issue.

yeah it does look like a dounut shape. When you talk about Pillows of air bubbles, do you mean like spots where the thermal past isnt applied beacuse if that is he case. yes there are spots on the CPU and heat sink. in other words the paste that is applied isnt completly solid. There are little spots here and there, like holes i guess you can say. Is that what your refering to? The paste is spread across the CPU but it looks like its kind of breaking up, so yeah there are tiny holes that look like some one sprinkled the paste on there and isntead of it being completly solid.

if i were to do this my self. Do i just apply a small drop with a static glove, in a clean room so that i dont get any dust or debree on it. Usually when applying thermal based compound, in the instructions it always tells you to placea small drop on the CPU it self. Then do NOT touch the drop or spread it in any way with your hand. Just place the heat sink over the drop and let it spread the paste it self onto the CPU. That is the correct method, right? Also when applying a drop, its no more then just a small finger size drop right?

So when i apply this paste. What should i use to wipe off the remaining old paste. Like cotton or something? Because cloth shreds and will leave resedue on the CPU. Terry told me to wipe clean both the heat sink and the CPU over any old paste that is left. Then apply the new paste.

After i do this task. Do you want me to Boot up my machine again and see if the temps raise. If the CPU is working and is seeting correctly and the heat sink is clamped down correctly. What temps should i be getting on idle for a working machine?

I recall an instance in a past thread where you reported that a SATA plug module became broken on the motherboard.
Did that occur on this current motherboard?

Yes it did. On this current mobo. It was a USB port actually i think. i though it was a casing, so i ripped it off with a pair of pliers, that was a mistake. But in any case i still have two others that work fine and each one has 2 slots for ports. Originally it came with 8 ports, but now i only have 4 ports because of the damaged sata module. That happend right when i built my pc though and after i got everything running, it worked fine. So i really don't think that would be connected to this current issue im having now.

Edited by terry1966, 21 April 2011 - 10:40 AM.

[jeff matthews]

Well originally i tried to take the casing off with my hands. But couldn't so t hen i used a pair of pliers. I didn't realize the ports were under the motherboard, i though they were under the casing. Some mobo;s are different and the ports are right on the top of the mobo. Also some usb ports have protective casing over them that you have to remove. That is how it was with my older motherboard. so thats what confused me in building this new machine. It was a general mistake i made on my part because i wasn't aware that the ports were actually tucked under the motherboard and the casing was not supposed to be removed. It was part of the module.
