Hi everyone,

I'm not sure I submmited this post in the right place.

My computer somtimes shuts itself down unexpectedly so I statred looking at the tempratures of the different components. I'm pretty sure most of the components are over heating. So I need your help to understand why. I used everest to give you as much information as I can because I'm no expert.

PSU : ENERMAX LIBERTY 400W
Chasis: Mambo ThermalTake

Hardware: http://img697.imageshack.us/img697/528/hardwarereport.p...
CPUID : http://img697.imageshack.us/img697/528/hardwarereport.p...
Temps: http://img638.imageshack.us/img638/5792/tempmu.png
Voltages: http://img638.imageshack.us/img638/5792/tempmu.png
Statistics: http://img822.imageshack.us/img822/1001/statisticsn.png
Cooling Fans: http://img822.imageshack.us/img822/5240/coolingfans.png

One other thing you need to know, the temps I showed you here is while the chasis is open and a huge fan is directed straight at it. When the computer was closed the motherboard was at about 70c when not stressed.

My motherboard was replaced 2-3 times before, I think the shop I bought it at have no idea how to build a computer. But now I don't have a warranty anymore, and I just want the computer to last as long as it can.

Please help me, Thanks alot in advance!!!

What is the system being for for when it shuts down? Do you really have three 8800 GTX in there with a 400W PSU?
June 26, 2010 3:42:17 PM

The RAM being in slots 3 and 4 shouldn't cause a system shutdown; the OP might be using slots 3 and 4 because of a large HSF that blocks the first slot.
June 26, 2010 3:45:53 PM

No I have only one GTX 8800 in there. Again, these temps were measured when the chasis was open with a big fan. When the chasis is closed the temp of the motherboard starts at about 75c and when I start a stability test the motherboard rises quickly to 88c and then the computer shuts down.

Another thing I find odd is that there is a temp for the cpu and temps for the two cores, whats the difference? Why is there such a big difference between the cpu temp and the cores temp?

You got us confused by providing a hardware list of at least two 8800 GTX. I agree that it probably shuts down because it overheats. What is the ambient temperature of the room where the PC is installed? What are the core temps?
June 26, 2010 4:40:30 PM

Sorry for the confusion, it was a report made by everest.
The room temp is about 30c.

At first when I checked the temps of the cores with the chasis closed it showed -40c with both cores, both in Everest and in SpeedFan so I thought it was not working correctly. But when I opened the chasis and directed the fan at it the core temps were at 50c when idle and rose up to 70c when in stability test.

I checked the fans of the cpu and the fan of the chasis and both are working.

So what do you think ? is it the PSU or the temps?
I took some pictures of the computer, maybe it will help?

thanks for all the replies!!

A few questions. Why aren't the memory modules in the same color slots? Shouldn't they both be in the green (preferred) or the orange slots for dual channel mode?

Since you're keeping your room that warm, may I suggest that you install a better CPU cooler? That sure wouldn't hurt. Maybe it's the picture that isn't clear, but the heatsink seems to be filled with dust (and so is the GPU fan).

The slot besides the GPU seems to be open. It should be closed if not used. You should also reroute the IDE cables to improve airflow in the case.

yes they should be in 1+3 or 2+4 not 3+4

You are correct. MSI don't use color slots like others. The manual recommends slots 1 and 3 if only 2 modules are installed.

I just downloaded the manual and I have more questions. What are the CPU Smart FAN Target and the CPU Min. FAN Speed settings?

If you haven't, I would suggest getting some thermal grease and trying to reapply the heatsink. It could have seated poorly, or whoever assembled the computer might not have applied enough or there may be bad contact.

I would definitely suggest getting some compressed air, taking the computer out back, and spraying all the dust out.
Double check all your fans are working properly as well.

Applying too much heat paste is even worse as it prevents proper cooling. A heatsink filled with dust also doesn't cool very well.

Thanks for all the help!

I cleaned the cpu and gpu fans with a vacuum cleaner, rearanged the cables and closed the chasis and these are the results:


When Idle the two cores were at about 40c and the motherboard was at 31c.
When in stability test the cores rose up to 63c and stayed there and the motherboard rose to 52c and stayed there. Are these temps considered normal?

The CPU smart fan target is DISABLED. What does it mean? should I change it?

The GPU tempratures during idle time are also worrying me, are they normal?
http://img687.imageshack.us/img687/2977/gpuu.png

The memories are at slots 2 and 4. Should I change it to 1 and 3?

Thanks again everyone!

Considering the ambient temperature, your motherboard and CPU temperatures are fine.

The CPU smart fan can be left as is, but if you set it to Enabled, then make sure that the maximum temperatures don't increase. What it does is to make the fan spin at a lower RPM if the CPU is cool enough as that reduces the noise level.

The GPU temperatures are fine considering the ambient temperature. What are they while running a test that keeps it 100% busy for several minutes?

You can leave the memory modules in slots 2 and 4, but your manual states that slots 1 and 3 should be used.
June 28, 2010 4:09:33 PM

Again, considering the ambient temperature, it's fine. I see no reason to run the fan at 100% if the temps are normal. It will spin up if the temperature gets high enough.
