S96J - 75ºC temperature

I'm having heat problems with my S96J...

Specs: T7200, 2gb 667mhz, Fujitsu MHV2120BH (5400rpm 120gb)
Idle CPU temperature: 47-50ºC
CPU at full load (Everest stress test): up to 75ºC
Gaming: up to 73ºC

I guess something is wrong. I assembled my S96J as described in Intel's assembly instructions, and it's working 100% fine besides the heat problems.

Which part may be assembled unproperly?

BTW, if I decide to apply Arctic Silver 5, should I remove the stock gray thermal interface in the heatsink? And I'm not familiar with the small CPU heatspreaders like Core 2 Duo's. Should I apply a thin layer of AS5 as always? That would result in a much smaller quantity than in Pentium4 CPUs.

Thanks

 

There is no heat spreader on the Core 2 Duo series. They are used mainly in desktop processors. 75/73 C is a little warm, but it won't damage the proceessor. If you are still concerned about the heat, then go for the Arctic Silver upgrade.

You will have to remove the old thermal interface, because otherwise, innefficient heat exchange between the processor and heatsink will result, which will mean a high temperature again. Apply a thin layer of Arctic Silver. Yes, it will be less than Pentium 4, but e Core 2 Duo processor also gives a fraction of the heat of a Pentium 4 out.

 

Thanks for the info

Also, is it ok to apply AS5 on the GPU in this model (and remove the stock thermal interface)? Will the heatsink be too far from the GPU (no contact) after I replace the old interface with arctic silver?

 

I'm still having trouble with 73 being a problem while gaming... It doesn't sound out of the ordinary to me but I'm not entirely sure what you expect to get it down to. My G1 can get up to 72 if I've been gaming for a while but I barely even feel it.

Maybe I'm missing something but I don't see the need to crack open your notebook and start fiddling with the innards for just 73 deg.

 

I'm not entirely sure on applying Arctic Silver to the graphics core. If there is a thicker pad there, then I would say no. However, if there is thermal paste, then I see why not. The S96J has a GPU and processor cooling system that is joined, so when you are applying the Arctive Silver on the processor, you may as well have a look at the graphics card, and see what thermal interface is used on it.

 

Yeah it's not a big issue, but, according to many reviews/opinions about this laptop, it rarely goes over 65ºC, even with the stock thermal interface. That's why I'm a bit worried, since higher temperatures = less durability in most cases.

 

Gaming, I do get 75 with my Z96J (same than S96J), but idle is 55.

 

I can understand modifying because you want better performance; I'd probably work on my laptop if I felt comfortable opening it up for anything but a cleaning. I think it just struck me odd that you called it a "problem" when, in my experience, that seems pretty standard with most laptops.

But that's me and I'm odd and I admit it.

 

Repeat after me 75C in a notebook at heavy use gaming or (especially) full cpu stress load is totally normal, and within spec for the unit..... 95-100 and you can start to sweat a little, perhaps .

The temps reported in reviews etc don't always reflect full load stress tests, and ambient room temps/playing surface can also play a role in the temps that you're seeing.

 

That temperature is fine but you might want to consider applying AS5.

As for applying AS5 on the GPU on the 96J series, I don't recommend it because the heatsink uses some pretty thick thermal pads to make contact with the GPU.

 

Yeah thats not bad man, I hit pretty much the same temps as you except I'm a few degrees lower on idle. Before I got my new motherboard I was hitting 90C under everest just for a comparison, you're fine
