Compatible Heatsink

I was wondering if we can use the 3700 series heatsink for the 2200, 2300 series because it looks like it would do better with heat.

 

The bottom one is the better one, since there's more copper? Hard to say if it would fit without measurements, but nothing wrong as far as the eye can tell, IMO.

 

don't know, but I was thinking the top(3700) one. The one on the bottom is from 2300 series and it's only thin copper sheet from the cpu part.

 

If the CPU is under the center of the 4 screws, doesn't matter as it's copper there direct to the heatpipe. On the left platform is probably the chipset.

For the top one, it could be better if the CPU (under the center of the 4 screws) goes directly to the copper and the chipset is kind of distanced from the rest and passively cooled.

So, no difference for the CPU if there is proper contact. (thermal paste is applied appropriately)

 

Not worry about cPU. It's more of the nVIDIA chip set on the left. Only if i can show a picture from the side level.

 

Or underneath.

I can tell how thin the copper is and how thick the same area on the top heatsink is.

NVIDIA GeForce Go 6100 seems to be ~8-10W. Not sure if that can be passively cooled.

CPU is ~31W.

Intel Atom is ~5W. oh man..

 

Here is my drawing
Red is copper

 

If you're quite convinced, you might as well purchase the parts and try do it.


And, if you can get a temp reading with HWMonitor or other for the GPU/northbridge, you can find out for sure which dissipates more heat.

 

That is just by eye-balling it. Only if i it's size description of how short how long. That's what i'm thinking. What's $5-$6 right?

 

How the CPU and GPU connected to the heatsink? Thermal pads anywhere?

Not sure what happened to the unofficial averatec forum.

 

i just used arctic silver on both cpu and gpu.
for the gpu, I'd added copper shim, but still hot.

 

Is it hotter than before? Not idea if the heat from the CPU could be coming down the copper to the GPU..

 

i dont know, that's why I want to try different heatsink like the 3700 where it straight to the pipe and not thru the cpu like the 2300.

 

Any reading for the GPU temp through HWMonitor or GPU-z, or Everest or Speedfan?

 

Didn't get that far. Installing OS and got hotter and hotter. Screen start to get distorted to point that it shuts off.

2nd thought was can we split the fan cable? just the +-. Install small little fan over the gpu. I really like this 2300 series. Only if it would work like other normal laptopl

Edited: I also tried installin TF20 with lower wattage which is also a socket s1 but that didn't recognize it. I know the TF20 works.

 

Sometimes for the fan there are 3 pins. If you know what you're doing, I guess you could do that.

Maybe could try temporarily run a giant fan over the CPU/GPU area with the notebook opened up when installing the OS.

For the other CPU, you might need a BIOS update if there is one, but don't try that until the thing is rock stable. :/

 

FYI- I'm the guy with the revised cooling mod. My Everex ST5340T is a twin to the 2370, except the AMD CPU is the next faster chip. The nvidia GO6100 is the same.

My mod brought down both the CPU temp by about 5C and more importantly the GPU temp by about 15C. After the mod, the CPU runs in the mid-40s and the GPU in the low to mid-60s. I use HWMonitor.

That factory thermal pad on the GPU is a POS. However the copper shim to replace it has to exactly duplicate its compressed thickness and be clean, flat (meaning parallel sides) with near mirror surfaces. You want as little thermal paste as possible - only enough to fill microscopic voids. It would have helped substantially if Twinhead (the 'real' manufacturer) had screw clamped the heat sink to the GPU the same as they did the CPU.

The redline for the nvidia chip is approximately 80C - - however, the more often the chip has been redlined, the lower the redline as the internal material matrix starts to breakdown and become less capable of transferring heat to the heatsink.
