HD 6970m repasting, also notebookguru's client service is non-existent.

I like trains.

 

I know how you feel, as I've dealt with my share of temp issues with this notebook (P170HM). Either your paste job was done badly, or the heatsink isn't seated correctly. You can take care of both of these problems quite easily yourself, all you need is a tube of thermal paste and a screwdriver. You may also want to get some of that compound used to clean off the thermal paste that's already there, although you don't need it. As long as you clean everything up well you should be good.

Also, make sure the notebook is on a flat surface, and it may help to use something to elevate the back. Restricting the airflow any kind of way on these machines can be detrimental to your overall temps.

 

Thank you for your fast response. As a matter fact it was your very thread on undervolting the 6970m that encouraged me to experiment with the voltages. I'm glad I did, as i can still play most games running the card at half of the stock clocks, and 0.7-ish voltages. Thank you for that. Funny that they didn't put taller rubber feet in there to begin with. Interesting that you have heat issues as well, I thought the P170 has superior cooling? Could you elaborate on how the heat sink is supposed to be seated?

btw did the repaste help you at all? What kind of differences are you seeing degree-wise?

Thanks!

 

wouldn't ic diamond be better? and also check the heatsinks to see if they are damaged or clogged. whats your cpu tempurature like?

 

I repasted my GTX560 lately and had temps decrease 1-3 degrees Celsius, depending on the test.

 

Crab Battle!11

 

My cpu ( 2630qm ) idles at about 45c - 55c, it never gets much hotter than that even under heavy load.

 

well compared to how much wattage each one uses(cpu and gpu) the temperatures are proportional.

 

First, you can reduce over 10c on the GPU with proper repasting. I'd recommend using Tuniq TX-4 for both the GPU die and memory chips (rice grain method). Remove the stock thermal pads from the memory chips and check the gap between the chips and the heatsink. If the gap is 0.5-1mm use a generous amount of paste on the chips. Don't worry about possible bleeding or conductivity issues, the TX-4 paste gets thicker under load and doesn't create mess.

In addition, check if you can slightly bend the heatsink to minimize the gaps.

Good Luck

 

Undervolting is a nice perk, but you shouldn't have to resort to that to keep your notebook from overheating. I just got my notebook back form Sager to replace a faulty gpu, and according to them they used IC Diamond. My temps haven't been too bad since then. I idle around 43- 46C, and a 3DMark Vantage run topped me out at 78C. When I first received my notebook I was getting high 90's like yourself. As far as the heatsink, from my experience getting it mounted just right and can be somewhat tricky, and I couldn't really tell you much other than just make sure it sits flush with the gpu core and make sure it's screwed down good. Also try to get all four screws equally tight to avoid any gaps or inconsistencies. Personally, I wouldn't mess with the ram heatsink, unless you're willing to replace the thermal pads upon removal of it.

Ambient temps also play a big factor. I'm in Texas and it gets over a 100 degrees some days. I've noticed my laptop runs a good deal cooler at night when it's not so hot outside.

 

Yea, well I agree, but what to do? Notebook Guru doesn't respond at all. I feel let down.

 

GPU memory chips can still overheat even if the heatsink sits perfectly flush and the core temps are fine. Thermal pads are ok but if GPU memory sensor hits 90c+ I'd suggest replacing the stock thermal pads with paste.

 

Where is the GPU memory located, if not under the heat sink? "Thermal pads"? What are those?

 

As far as I know there are no temp sensors for the actual memory chips. There is a MEMIO sensor that reads temperatures for the memory controller, which is located on the actual gpu die covered by the main heatsink.

 

eight black rectangles around the GPU core are the memory chips.

The sensor is located on the die but it does read the temp directly or indirectly from memory chips. Try playing with different TIM on memory chips and you'll notice a huge difference in the MEMIO temps. BTW, Shader and DispIO temps will also be slightly affected.

 

Oh ok, interesting. I always assumed all the sensor readings (DispIO, MemIO, and Shader) were solely based on the inner workings of the actual die. Ideally they should be pretty in sync with one another, but depending on how the main heatsink is mounted (such as one side being tighter or having more contact with the core) these readings can vary quite widly. For example I've seen as much as a ~15C difference between the core and shader temps on a badly mounted heatsink.

 

where can i found Tuniq TX-4?,it seems performs beter than everything else.
im from greece,do you know anyone who can ship the paste here?
thanks a lot

 

It's not the best paste but it's a good choice for gpu memory chips. I'd also recommend the MX-4. You can probably get it of eBay.

 

so my friend which is the best paste solution for our(gpu,cpu?)
thanks

 

The two most popular choices are IC Diamond and Arctic Silver 5. Some people complain that IC Diamond is harder to apply though (it's thicker - but since you don't spread it, it's not too bad anyway).

 

IC Diamond took me all of about 2 minutes to apply once I figured out how to take off my heatsink (I thought the whole thing was screwed in!!!).

 

If you're only worried about the CPU and GPU die - ICDiamond, MX-4, OCZ Freeze, Tuniq TX-4, AS-5 will all work fine. However, if you also need to replace the pads on GPU memory chips - MX-4 or TX-4 would be the best, IMHO.

 

Do I have to replace the pads, if I repaste the GPU ( hd 6970m ) ?

 

Raise the back of the laptop when gaming. The one shortcoming of this design is that the rubber feet are too short on the back. Notebook manufacturers really have to start building in angled feet that can flip out like on most keyboards. Just raising the back of the laptop an inch can dramatically lower your temperatures.

People have used books, doorstoppers, commercial products (heat balls, laptop stand hooks, notebook coolers, etc.) to do this.

 

If your pads are in good condition, you may not have to, but with pads once you remove the heatsink, the pads are generally squished and compressed and sometimes broken. Fresh pads will properly mould themselves to the shape of the ram/vrms, etc. and provide the best direct contact for heat transfer. Old pads will be dry, cracked, brittle, and won't make good contact anymore since they are already deformed.

The actual heatsink plate is very easy to take off and put back once you repaste the core. IC Diamond compound seems to be the most popular and offer the best performance but it won't have dramatic results like would expect unless the original thermal compound application was horribly done (too much leading to insulation).

The best thing is to raise the back of the laptop so in the intakes have room to breathe. This has more effect than any repasting ever will.

 

Well, thing is: I AM using a lappy cooler by cooler master, yet it still runs at over 90 degrees if I don't undervolt. It is summer here, so it gets quite hot, but still... consistent mid 90's ? Also, 1) does the GPU have pads I have to swap when I repaste the actual GPU chip 2) where can I get said pads, what model of pads?

Thank you so, so much.

PS. The Intel n-6230 wlan chip is also pretty bad. I'd advise to avoid it

 

My 6230 is great. Just make sure it's installed properly and the drivers are up to date and you are good to go.

 

I still need some info about those thermal pads any knowledge is appreciated!

 

I just gotta know what I', gonna need so I can have everything at hand when I take this thing apart

Thanks!

 

If you are just repasting the GPU core you don't need pads.

 

hi just recieved my 6970m!!at the heatisink there is a grey square!i must remove it or not?thx..

 

The grey square is probably your thermal pad; if you have your own thermal paste, then yes remove it (I recommend using a little bit of alcohol) that way you can apply your own paste.

 

i remove it and repaste with arctic silver 5!!my idle is 51 celsious!!room temp is 30.5..is something wrong??

 

Make sure you didn't use too much AS5, you should be aiming for an amount the size of a grain of rice generally. Using too much can have a negative effect because it'll cause insulation instead of transferring the heat. Also make sure that the heat sink is seated tightly and evenly; check that nothing is holding up one side more than the other when you tighten it in.

You don't need to spread the AS5 either, just put a little bit, the size of a grain of rice, on the chip and when you tighten the heat sink the pressure will evenly spread the paste.

I don't think 51C is all that high of an idle temp for a 6970 anyway though; what is it's temp under load?

 

A bit off-topic but since it's my thread: Is there any way to disable hyper-threading for the p150hm?

 

i spread it my self but i put twice the amount of a grain of rice...do u recommend to repaste with ur method?thx for ur help!!

 

here is my full load temps after running 3dmark06.

It would normally be in the BIOS but I've heard that the Clevo/Sager BIOS are pretty limited, so you may not be able to... Unfortunately I do not have my P151HM1 yet so I can't check myself, but from looking in the manual it doesn't seem like it will let you.

Most of the load temperatures I've seen are in the upper 80's, so your max isn't too far off. You may also want to make sure you have adequate airflow underneath the laptop (possibly raise it up about an inch or so using books or something); if you want to you can repaste it, but it will probably be fine. Are you running your fans at max (fn+1) or letting the BIOS manage them? Also, in an actual gaming scenario your card may never really go that high, since the benchmark pushes it to the limits.

 

i tried some games crysis 2,metro 2033 and my temps gone 97-98 celsious in 3 mins..what is wrong???

 

Definitely repaste it and make sure it's seated evenly and tightly then, that is pretty high. Make sure nothing is blocking the fan's intake as well.

 

Something is wrong with your cooling system. Make sure the laptop is on a flat surface with no vents obstruction. Check the fans, they should be quite noisy during load. And of course, repaste the CPU and GPU.

 

maybe the heatsinks of the gpu or the gpu are faulty???

 

Faulty heatsinks would be unusual. They can only be "faulty" if they're physically damanged. If you check out the heatpipes and they're bent/dinged/crimped, then that could explain high temps.

 

hmmmm.i thing the heatisinks are fine.no bent or something.what can be wrorg with my gpu and the temps are so high??

 

Is it really ok to repaste the gpu without replacing the pads? I was going to use AS5 initially but then I decided to be on the safe side and use Mx-4 which is completely non-conductive.

 

Have you checked the fans during load, they may be malfunctioning. I'd also remove the HS's and examine the stock paste, maybe they forgot to put one at the factory. There have been cases of stickers/tape stuck between the CPU/GPU and HS, lol.

It's fine, though I've been replacing pads with paste for a year and so far zero issues. Temps are always better with paste.

 

sorry for asking this but im really noob

Replace thermal pads with thermal paste means take off the thermal pads and puts "grain of rice" size of thermal paste on every memory chip on GPU , am i understand that correctly ?

 

Bump for great justice.

 

Yes, that's correct

 

I´m sorry, but notebookguru is in germany well known, that if you´ve got a problem, he is hardly getable. For some buyers it was unpossible to get a RMA. That won´t help you now in this moment, but maybe it prevents other to buy at notebookguru. The service is the miserable.
