My G51 is a hot potato,Help!

^^^^^ I agree to a certain extent! 100c is crazy hot, I don't even like 88 - 93c, but that seems to bethe way it is!
The biggest comtributing factor I see here is so many folks trying to run these "performance" Notebooks at Performance Desktop settings / levels....crazy man, their simply not built to this standard....NO AIR FLOW!! My high end desktop has 7 x 120mm, just for cooling and it still screams for WB's
These things simply aren't designed for Stress Testing, OC'ing or Benching and thier seems to be quite a few folks that are doing just that.....get a Desktop.

I do have a "bit" of the bug, even with a Notebook, did have to install nTune and ramp the 260M up to nVidia Defaults 550 / 1375 / 1900...temps up slightly, from about 89c to 94c "in game"....all seems fine with 195.62 WHQL.

 

Wow, I finally got my ICD7 and I did not expect to see such drastic results! This is insane. I played DoW2 for roughly 2 hours in each case.

Previously, the CPU had AS5 on it and the GPU had the stock crap. That stock crud on the GPU was terrible. So damn hard to get off since it was rock hard. ICD7 is pretty thick (almost like putty) but I just blobbed it in the middle of the GPU and let it spread out naturally. I put quite a bit on since I read you need to and the GPU is quite big compared to the CPU. But look, a 10C drop in my GPU temp!



Also, not sure if this matters, but 2 of the GPU memory modules didn't have any thermal pads on them. So I cut 2 pieces as I had some thermal pads I bought a while ago which I had never used. The 2 purple ones are the ones I cut out and the red circles are where they make contact on the heatsink.





So these are all the things I've done to lower my temps

1. Undervolted CPU
2. Copper heatsink block mod
3. ICD7 on CPU & GPU
4. Notepal X2 notebook cooler (though this only helps for idle temps, for load temps it does nothing...blame it on the G51's lack of vents on the bottom)

I still plan to undervolt the GPU (which I'm having trouble doing atm) and I also just ordered a replacement bottom panel which I'm going to mod like removing that stupid fake vent/subwoofer thing. Hopefully the notebook cooler will become more effective then.

This is what my copper block mod looks like. I have since removed those 3 bottom blocks since they obstruct the GPU vent. Removing them has actually lowered my GPU temperatures by a couple degrees. More isn't necessarily better. The heat can't go anywhere if there are too many copper blocks crowding the place. It needs space too.

 

Splendid, grasshopper.

 

The process of getting those results are uncontrolled, but a 10*C just by replacing the thermal paste on the GPU is very good. That was your biggest bottleneck here.

The two purple thermal pads you applied on your GPU aren't over memory chips. Those are voltage inductors, or MOSFET's. They don't produce a lot of heat and do not need thermal pads.

The long "slotted" copper blocks you have setup will perform at it's best when aligned with the intake airflow direction of your fan.
