dv5 9600 GT Temperature figures???

I am writing with reference to the below thread and because the thread was closed, I then started a new one.

My dv5 is almost 2 years old and this is my dv5 specs taken from PC Wizard 2010:

I am writing this thread as I found the HP notebooks are suffering from bad cooling system, and I said why not focusing on my dv5 cooling system and see if it's acting normal or no.

Here are the temperatures reading from CPUID Hardware Monitor V. 1.09.0 in a room temperature of 21°C.

Hardware monitor ACPI
Temperature 0 45°C (113°F) [0xC6E] (TZ01)

Hardware monitor Intel Mobile Core 2 Duo P8400
Temperature 0 38°C (100°F) [0x40] (Core #0)
Temperature 1 40°C (104°F) [0x3D] (Core #1)

Hardware monitor NVIDIA GeForce 9600M GT
Temperature 0 64°C (147°F) (GPU Core)

Hardware monitor Hitachi HTS542525K9A300
Temperature 0 49°C (120°F) [0x31] (Assembly)
Temperature 2 49°C (120°F) [0x31] (Air Flow)

I can see from the above given readings that my CPU temps are fine, but I am worried about the GPU temp, the temp is quite often jumping to 70°C while doing Internet surfing with IE and nothing more. And I hear the acceleration of the fan when the temp is reaching 69-70°C, then it cools down to 55-65°C and after awhile it jumps to 70°C again and so it continues.

On Idle, The temp of the CPU is about 30°C and the GPU is about 40°C.

As I said the CPU temps are quite fine, I ran video converting tool for about 30 mins and both of the CPUs were busy at 60-65% and I got a max of 60°C.

What can you tell from the above readings? Do you tell me that my GPU temperature is abnormal? And what do you suggest to improve it.

 

This is the result when I ran a multi thread benchmark on PC Wizard

Hardware monitor ACPI
Temperature 0 59°C (138°F) [0xCFA] (TZ01)

Hardware monitor Intel Mobile Core 2 Duo P8400
Temperature 0 50°C (122°F) [0x32] (Core #0)
Temperature 1 51°C (123°F) [0x31] (Core #1)

Hardware monitor NVIDIA GeForce 9600M GT
Temperature 0 70°C (158°F) (GPU Core)

Hardware monitor Hitachi HTS542525K9A300
Temperature 0 46°C (114°F) [0x2E] (Assembly)
Temperature 2 46°C (114°F) [0x2E] (Air Flow)

Now and after 5 mins of the test is finished, the fan is still on acceleration and the CPU temp is down to 38°C but the GPU is still 69°C.

 

I would not worry about it, my dv6700 GPU(8400gs) goes to 80°C and up when playing bf2142 and my tx-2 GPU(ATI HD 3200) seems to like 65°C even when on idle ( i have not had the guts to play any games since even internet games seem to make it go past the 80°C mark. I'v had my dv6700 for 3 years(lots of game-play time) with no problems and the tx-2 is about a year old. If you really feel the need to cool the GPU down get a cooling pad they are cheap and actually work.

 

If you realy want to get dirty, you can disassemble it and clean the vents. That improves the airflow since the vents get stuck with all sorts of junk ranging from dust to hair. If you do that you might as well clean the original thermal paste and change it with arctic silver (around $10), that should give you better conductivity between the CPU+GPU and the heatsink hence lower temps. There are videos on youtube showing how its done.

 

Do you use a notebook cooler or just sit the notebook on a flat surface? Have you tried to lift the back of the notebook a couple inches?

My GPU temps at this time are 42C (with a cooler). I also overclock my GPU which means I run RivaTuner to manually select the GPU clock speeds. During normal use I "downclock" to about 200/200/400 (core/shaders/memory).

What are your clock speeds? Do you overclock?

Thank you for your inputs.

As I said earlier, I get the temp 70°C when I am surfing through IE, is this normal. The good thing when the temp reaches 70°C the fan starts accelerating and the temp falls gradually. But do you think 70°C is normal when surfing the Internet?

In fact I was told to take apart the laptop and install copper shims on the chip sets, I am ready to do this if this is going to reduce the temp and increase the life span of the motherboard.

I am asking, do I have to install the copper shims on all the chips, the CPU, GPU and the Northbridge? As per the maintenance manual, it is mentioned that thermal paste shall be used for CPU and thermal pads for the GPU and the Northbridge.

Do you think thermal paste is enough for getting temp down, or you recommend installing copper shims?

Thank you for your inputs.

No I don't use the cooler, I am just elevating the notebook from the service by 1" by using two mineral bottle caps.
No, I don't overclock and how to get the clock speed readings?

 

You cant put copper shims on you cpu or on the gpu since there is a heatsink on them, I would just clean the vents and take the thermal pad off the GPU and put in thermal paste (arctic sliver) since it has much better thermal conductivity. Also cleaning the original thermal paste off the cpu and replacing it with arctic silver will help since HP puts cheap paste and it looses its conductivity over time. So I would not put copper shims anywhere. Here is a disassembly video : YouTube - How to take apart your HP Pavilion DV5 Laptop Timelapse and here is the service and maintenance manual : http://h10032.www1.hp.com/ctg/Manual/c01550108.pdf (it has good pictures)

 

Actually you might need to get a copper plate to put in between the GPU and heatsink, because if its like my tx-2 it has a thick rubberish pad between the gpu and the heatsink so if you take it off there will be some space in between and you could burn your gpu. What I did was I got a 1900's penny and I sanded it down so its even and I put thermal paste on both sides and I put it between them now my GPU tems drop almost instantly when the fan turns on and the overall temps are lower.

 

Lets hope that showmak's notebook does not have a thermopad. My dv5t with a 9600m used thermo paste for both the CPU and GPU. I did re-apply arctic sliver about a year ago. If I recall the 9200m option used a different heatsink that used a thermopad.

If your system has a thermopad then I would assume that you have the incorrect heatsink installed. If that is the case I might suggest looking into replacing it with the correct one. The service part numbers would be in the dv5t service manual. If you need a link let us know.

 

Yea like I explained my tx-2 had a thermopad, so when I removed it I just put a sanded down copper penny in between, if it does not have a thermopad the procedure would be much easier, just clean the old paste and change it with new paste. Feel free to add to my reputation if I have helped

 

Guys, sorry for my late reply as I have totally forgotten about my old laptop because I was not able to get the Arctic Silver and then I gave up and bought a new laptop, but recently I luckily got the thermal paste "Arctic Silver" and I thought of continuing improving my old laptop.
So where do you think I shall apply the thermal paste and where to install the copper shim?
Attached are the pictures of of the fan and heat sink (there is a thermopad) and the motherboard showing 3 chips. I would like also to know which one is the GPU and and which one is the CPU and what is the third one...

 

My DV7T 9600M GT runs around 175-190*F almost all the time while gaming. It seems the GPU likes to run hot. It idles around 135*F with a cooling board on my desk.

 

I realize this is an old thread. For reference only, for anyone here because they are doing research on copper shims:

Be aware Canadian pennies of the correct years are preferable to the best American pennies. Canadian pennies have a higher percentage of copper. Here is a reference:

1 cent

The 1982 to 1996 Canadian pennies are especially good and are readily available. They are thinner and require less machining. USA pennies, at only 95% copper, cannot match the thermal conductivity of Canada's coins.

For those with no budgetary constraints whatsoever, USA 1964 and earlier silver dimes have higher thermal conductivity even than Canadian pennies. However, the cost of such dimes, even just in "scrap silver" condition, is about $2.00 each. Also, silver is even more difficult to machine than copper, and if you mess up a dime your mistake really costs you.
