CPU High Temperatures

[LGhost94]

Hi guys,

This is an old PC, it's a core2duo e6400. I'm getting like near 80º while stress testing. I think this is not normal. I must not exceed 60º right ?
I've tried to see what's the problem but with no success, so i'm here trying to get some ideas from you guys. Here's what I've tried:

New thermal paste (it's not the thermal paste)
I changed the CPU to an e4300 (i did get better results... like 65º while stress testing)
My final though is that it might be the cooler... I'm using an Alpine 11 GT Rev. 2

Should I try with the stock cooler ? (I have one here around somewhere)... Can it be the windows giving me wrong readings? (I just change the motherboard and the cpu and did not formated)

Thanks in advance for all the help you guys can give me.

the stock cooler have cooper base on it while the Alpine 11 GT Rev. 2 doesnt maybe you should try with the stock first

The Alpine GT isn't a fantastic cooler for overclocking or stressful use. What stress testing are you using, Super Pi?

What case do you have? Is there a reason you're using a low-profile cooler?

In a poorly ventilated case I wouldn't be surprised at 80C.

There's no reason just had that cooler around and decided to use. Will I get better results with the stock cooler ?
The case is a cheap one not very well ventilated. but with the case opened I get like 75º still I think it's too much right?
IDLE I get around 45º-55º and the c2d e4300 35º-50º

You very well might get better results with the stock cooler. Certainly try it. After-market coolers aren't always better.

Try the stock if you still get above 70 even you open yours case, you have thermal problems

The stock Intel cooler or the equivalent you used can be tricky to install.
A poor installation will result in higher cpu temperatures.
Look at the back of the motherboard to verify that all 4 pushpins are through and locked.
There should be no wiggle if you nudge the cooler.

Too much paste will act as an insulator, more is NOT better.
All it takes is a small drop that will spread under heat and pressure.

To mount the Intel stock cooler properly, place the motherboard on top of the foam or cardboard backing that was packed with the motherboard.
The stock cooler will come with paste pre applied, it looks like three grey strips.
The 4 push pins should come in the proper position for installation, that is with the pins rotated in the direction of the arrow,(counter clockwise) as far as they can go.
If you want, play with the pushpin mechanism until you know how they work.
Place the cooler so that all 4 pins are oriented over the holes in the motherboard.

Push down on the entire cooler so that all 4 pins are through the motherboard.
When you push down on the top black pins, it expands the white plastic pins to fix the cooler in place.

The trick to getting it on is to push down on a DIAGONAL pair of pins at the same time. Then the other pair.
If you do them one at a time, you will not get the cooler on straight.
Lastly, look at the back of the motherboard to verify that all 4 pins are equally through the motherboard, and that the cooler is on firmly.
This last step must be done, which is why the motherboard must be out of the case to do the job. Or you need a case with a opening that lets you see the pins.
It is possible to mount the cooler with the motherboard mounted in the case, but you can then never be certain that the push pins are inserted properly
unless you can verify that the pins are through the motherboard and locked.

If you should need to remove the cooler, turn the pins clockwise to unlock them.
You will need to clean off the old paste and reapply new if you ever take the cooler off.

In the end, do not worry too much.
The cpu will slow down or shut off if it reaches a dangerous temperature. That is on the order of 100c.
