Latitude D630 NVS 135M copper mod

Hi guys. My motherboard was replaced couple of days ago by DELL technician (GPU problem). Now with new mobo I have GPU temps uder stress up to 100C. Its too much I think. My question is what is your temperatures? I´m thinking also about copper mod of cooling system, but not sure about thikness of the copper shim for D630, I know that for XPS1330 it is 1.5mm . Do you have experince with that? Thanks

 

I'd use something thinner than 1.5mm, like 1mm, but if you can, it's best to check out the thickness of the heat pad on the heatsink, and estimate from there.
You can check out the guide I made for the E6400 in my signature.

 

When they replaced the motherboard, did they replace the heatsink? If not, I would ask to get it replaced, because when the heatsink is removed and replaced, it won't work as well as the first time.

 

I use 0.5-0.6 mm copper with very thin AS5 both side. Now my idle temp. is about 45-50oC, Max 73oC. Room temp. is about 26oC.

 

Thanks for help, guys. Dell technician didn´t replace heatsink. So it seems to be his fault. I have called DELL support so on Thursday will come again with new heatsink and motherboard. But I´m still planning to do mod with copper shim. I don´t want to pay for new mobo after warranty expired.

 

As much as I stress my D620, I've never gotten higher than about 170F for the GPU. Everything is stock. Perhaps you should try raising the back of the laptop up a bit so the airflow is improved?

I'm sure that temperatures will be better during the winter though.

 

firstly getting those sort of temps means u have other worries than doing a mod , did the tech replace the gpu thermal pad as they are really only a 1 use item

check the heatsink is making full contact (take it of and look at the heatsink make sure its left a nice and square imprint) and screw it down evenly

check your vents are clear , im sure they will be if its just been taken apart but check anyway

and as a robin suggested raise the back of your machine to let more air in

i was close to hot gluing a couple of plastic rods along the bottom of my d620 when i had it so that it permanently had supports either side of the vent on the bottom to make sure it always had plenty room on any surface but i never bother ...

 

The docking station alignment ports and holiday light sockets worked perfectly, so those were the contact points for my laptop stand.

 

So after replacement of mobo and heatsink temperatures dropped.
LOAD temps (3D Mark05):
CPU: 65C
GPU: 80C (before 100)

Idle:
CPU: 38C
GPU: 55C (before 68)

So now I'm satisfied with temps and I hope that this 4th motherboard will last longer than 1 year.

 

Over 80degC, and the nvs140m in my laptop conks out and starts doing bad things.
