D945GCNL Core2Duo E6600 processor heat up to 75 C ... Max TDP 65w

[sachinm]

Hello,

Recently I have replaced my cpu processor to Core 2 Duo E6600 where Max TDP is 65w.

Motherboard D945GCNL.

This processor heat frequently to 75 C- 77 C when doing some cpu intensive activity like Picasa refresh, Benchmarking, etc.

Kindly suggest solution.

Regards,
SachinM

Hello.

You should check the thermal paste, and also if your heatsink is fully seated.

Just for curiosity: Do you got a Core2Duo nowadays?

Seems a little warm. The processor should be around 60C when it's busy:

My E6750, never gets above 45C-50C in my Optiplex 755, but it has a HUGE aluminum cooler.

You can replace the thermal paste on the current CPU cooler (get a good quality one), or just buy a new cooler, like this one:

I had a Core2Duo too and it never passed 55c (when thermal paste was in good state)

 

[AntonyLovric]

When you changed CPUs, did you replace the thermal paste? (Or were the coolers attached to the CPUs?)

Hi,

Changed processor recently. Buyed used one from ebay.

Thermal paste is not branded. It has (Original Intel Celeron D 347) hitsink & Fan.

The thermal paste is black color and I have pasted fully on it. Hitsink & Fan are proper. When processor start heating the fan speed increases.

When Computer starts in BIOS it shows 61/62 C.

One more query, if processor continues heating at 75 and go down. And it happen frequently then what can happen?

Thanks,

Celeron Heatsink pro0bably not strong enough to remove the heat the C2D is producing. Did the C2D come with it's own standard heatsink?
If not, time to think about getting a better heatsink.

 

[sachinm]

Celeron D 347 has max 85 TDP.

 

[ktolo]

Celeron D 347 has max 85 TDP.

Really? Ok - i stand corrected!

 

[AntonyLovric]

I think there are two(2) versions of the 'Celeron D 347'. (According to wikipedia). If the temperature is 'spiking' up and down, I would suspect the fan might be failing.

If you run the computer with the case open/off and have a fan pointed at the case does the problem persist? (The case fan might be failing as well).

 

[sachinm]

Yep! .. I was unaware of 2 version of Celeron D 347. Well, I have kept my processor aside. I will check the SKN value and see whether earlier processor was 65w or 86w. If earlier processor was 65w .. then also its Hitsink / fan can work with Core 2 Duo E6600 which has same 65W then... isnt this?

Thanks,

 

[AntonyLovric]

If they are both 65W TDP, then they should have similar temps. You need to remember they're different processors and 65W is approximate. The two processors have different frequencies, L2 cache size, # of transistors. (The E6600 should run a little hotter than the Celeron D at similar speeds.)

 

[sachinm]

Thank you Antony & All for giving valuable information. I will do all the findings and update you soon if no issue I see.

Thanks Aefuan

At last my processor temperature came to normal 45-50 w.

Thanks all for recommendation. I removed hit sink and reapply it using thermal paste. This time I am lucky. Seems earlier it was fixing issue.

Thank You
