Intel D945GCCRL Overheating?

[criminal666]

Hello Everyone I am running a Intel D945GCCRL with a Intel Pentium D 805 2.66Ghz DT 533FSB Socket 775. I also have 1 GB of PC4200 DDR2, two HD one SATA and the other IDE, and one DVD ROM Drive. I have a brand new Masscool 8WA741, along with a brand new 500Watt Ultra power supply. The problem is my PC will run for 10-15 min and then automatically shut off. When I hit the power button again it is does nothing! Sometimes it will start to turn the fans but thats it! The PC does not boot up. After a while of having it off and unplugged it will boot up again. I have tried two different CPU fans and the same problem with both! I do not know what else to do! I am going ****in crazy here! I have tried to remove and reaaply the CPU grease/paste which came with the CPU fan.

It does sound like an overheating issue. A few tests can help determine this for sure.
One is the room fan test. Run the pc with the case open and a room fan blowing on it and see if it does the same thing. A bit over the top, but it works!

Failing that, an excellent way to test your temps is to enter your BIOS and check your CPU temperature from there. If you have a problem with the heatsink/fan on your processor you should see a high temperature right away. I'd say anything over 50 degrees celsius on a chip like that is a sign of a problem. This will send up a red flag right away if it gets that hot that fast. Either the heatsink/fan is not spinning or it is not properly installed.

If your boot temperature is fine, that means it's heating up while the pc is running. You can use a program like coretemp or sensorsview to see your temps in real time. Either program will give you a warning when the temperatures pass the operating threshold.

It might not just be the cpu that is overheating - your video card, chipset northbridge or the inside of your case can be getting too hot as well, which will heat everything up and cause the system to shut itself down... it's a failsafe so components don't get damaged.

What are you usally doing when it shuts off?

It's always possible that overheating is not the problem. Let's try these things first and see if we can't eliminate that as a possible cause. If possible, post up a screenshot of your temperatures with sensorsview after running it for about five minutes.

If you are having an overheating issue, buildup of dust can be responsible for poor airflow in the case which leads to overheating. Cleaning out the case with a can of compressed air might fix your problem entirely. Does your case have any fans in it? Are they spinning when it starts up? I strongly recommend ALL computers to have at least 1 exhaust fan, but one front and one rear fan is ideal because it blows cold air in while blowing hot air out.

Ok well my PC starts up at 49-50C and rises. Not doing anything just sitting in the BIOS it rises. I have tried two different fans so I personally would not think that its the CPU fan being installed incorrectly. I have sat with the case open and the same thing occurs. I have two fans in the case, one bringing air in and the other sending air out. Airflow goes front to back.

Use a small desk fan, blowing into the case. If that brings the temps down, then you have an airflow problem. If it doesn't then the CPU heatsink isn't properly set.

[criminal666]

If the CPU heatsink isnt set properly could that be that its defective or just that its mounted wrong?

[mjc]

Mounted wrong or the plastic covering the compound hasn't been removed...

[Heartborne]

That is definitely too hot. Is this the CPU temperature according to the BIOS? It sounds like your CPU fan is not installed properly. Please consult this link (http://www.youtube.com/watch?v=OFEOd7nQbuQ) for proper instructions and figure out where you went wrong.

Checked out the video and I followed properly. The Processor fan I am currently using is this model:

Masscool 8WA741

So its installed a little differently. It came with a plastic piece which goes under the motherboard and the fan screws into. I have done this and screwed the screws as tight as they go.

[criminal666]

I had the case open with a fan running and it shut down at 57C

[mjc]

Was there a little white square on the bottom of the heatsink?

If so did you remove a piece of plastic from the white square?

[criminal666]

I guess I better ask. Do I need to take that plastic piece off? The one that wraps around the fan? I was going by this pic so I figured I didn't need to!

Are you talking about the black bracket like piece or more like cellophane?

What I'm talking about would be cellophane/plastic shrink wrap.

[criminal666]

Was there a little white square on the bottom of the heatsink?

If so did you remove a piece of plastic from the white square?

Nope no white square on the fan/heatsink nore the plastic piece under the motherboard.

[criminal666]

The black bracket piece. It says "Made in China" in the picture

[mjc]

OK, part of your problem , then could be lack of thermal compound between the heatsink and the CPU.

[criminal666]

Well I have applied and reapplied the compound that came with the processor. Its a silver color compound.

[criminal666]

Do I possibly need something other then what is shown in the picture I posted? Thats all I have on my CPU

Internal Temp 27C
Remote Temp 25C
Processor Temp 57C

PC is just on the BIOS display of temps so nothing is running but this!

[Heartborne]

with a huge heatsink like that you shouldn't be getting such high temperatures. Either it's not installed correctly or you haven't got the right amount of thermal paste on there. With that kind of cooling your temps should be around 30 degrees or lower.

Do you still have the stock fan? Try uninstalling the after market fan, wiping the surface of the processor clean with a dry cloth and reapplying the thermal paste evenly before reinstalling the stock fan, then check your temps again.

When applying thermal compound you should apply a thin, even layer on the surface of the chip. A little glob in the middle won't do it. You've got to spread it around.

[criminal666]

Did that and the market fan had the same problem:(

[criminal666]

Anyone have any ideas? I have done all that has been discussed here. Is it likely that its the motherboard or processor? I don't understand why none of these suggestions would work for me? Should I try another processor fan and heatsink? I have no idea. When I put in the market fan the PC starts at a higher temperature then the Masscool fan so I know that the fan is atleast better then the stock fan.:)

[Heartborne]

At this point it sounds like you've got a defective CPU... after all, if you correctly applied the thermal paste and installed the heatsink/fan correctly, you should be running between 30 and 40 degrees celsius, depending on air flow.

On that note, how many fans does your case have? Maybe you have an air flow issue?

I would recommend bringing it to a local pc repair shop and telling the tech what is going on here... I'm stumped!

[criminal666]

I have a fan in the front and a fan in the back and then the CPU fan/heatsink so 2-3 fans depending on how you look at it. Thats all my case can handle. I have one in the front bringing air into the case and one in the back pushing air from the case.
