M4400 Bios A13 - hot hot hot!

I'm pretty satisfied with the GPU core heatsink contact on mine,going by the spread of the tiny blob of Tuniq applied,but two of the memory module TIM pad's,hardly make contact at all.
Have you experienced some of this downclocking that other's have tallked about?
BTW,I did that HWmonitor test with the coolslice on,will do it again without it to see what difference it make's.

 

Without the coolslice on,same thing wprime then 3dmark.....coolslice sort of has anything but a cooling effect under heavy load.
It's interesting how the fan under bio's A13 will stay on low until my highest cpu and northbridge temp's are reached in wprime before deciding it should maybe speed up to 3500rpm,and lower the heat a bit.


Also cinebench with P8600 and X9100 just to show benchmark comparison between the two cpu's in the same notebook.

 

@Weegie

wow that's a huge difference! And one that would be very helpful for me. Are those temps what you reach with the X9100? That would mean it's not much hotter overal than mine...interesting Would be a great upgrade....would you consider a quad-core or you think it'll push it too much temp wise?

 

On a practical note - ain't really much difference at all between the faster Duo CPUs & the Quad CPUs as far as idle temps go; in fact, a Duo would have suited me just fine except for the fact that I demo 3D in real time, and spend some prep time beforehand encoding video streams.
With load, I get similar temperatures to Core2Duo CPUs, and in most cases, even lower.

 

hmmmm...ok...i'll have one then I guess it'll just come down to applying the right paste in the way it should then? I just don't want to buy a X or Quad only to see my GPU heating up (through the CPU's higher temp) now that i got it down to 82C max under load. What BIOS are you running now btw ofelas? And the copper mod, just cut a thin plate to the right size place it between cpu/gpu and heatsink?

 

LPTP-LVR my max temps under load are all under 78 degrees - see the file below.
A copper shim mod won't really benefit the CPU & GPU as both their heatsinks have copper contact inserts.
11mm x 11mm x 1.5mm for the Northbridge.
The GPU is 14mm x 14mm but I *only* used it as my heatsink does not make full contact with the GPU die.
I don't use a copper shim for the CPU.

Lot's of VM,rendering,the quad's a bit of a no brainer imo if your software support's it....ofelas's cinebench show's this quite well.
I bought the X9100 because I thought it would suit my usage better.
Temp increase over the P8600 is significant,but still well managed,I was actually surprised the GPU temp's only increased 5-6degC considering the cpu run's 20degC hotter under load.
My ambient temps,are pretty low 12-15 degC at the mo.

 

The same deal with the P8600 cpu running A13 bios and then A02
Big difference between the two bios version's.
A02 is annoying how you have to enable powermizer otherwise the fan doesn't want to turn off at all.
Wprime is quite a lot slower to run with the P8600,but it is an amazingly cool running cpu

 

That is one cold blooded CPU alright.

 

Whoa... have a look at this: I chose the P8600 because I opted for the Quadro FX 1700M, but under light load, mine is running much hotter than yours!

​

Now I wonder if the connection between CPU and cooling system may be poor, as it has been reported by a couple of persons. The BIOS is A13, and I'm aware of the fact that GPU and CPU share the same cooling system.
What do you guys think, should I call Dell?
