MSI GT70 2OD Heat Issue/Need advice

Well where to start?
Well first the hardware
i7 4700mq and GTX 780m i think that is all you need to know

!storytime!

Well i bought this Laptop almost 3 months ago and after 2 weeks temps where rising rapidly so i changed thermal paste like any normal person would do and that worked pretty well.
What thermal paste i used? Noctua nt-h1 both for GPU and CPU.
Temps where fine for 2 months after a week ago from now 7-7-2014.
The CPU was rising temps again like the old thermal paste but GPU was still fine but since you need to remove the heatsink from the GPU also to replace the CPU thermal paste i was like wth let's do both.

Now the CPU temps are fine but the GPU are worse now so i bought Gelid Extreme but without any luck.
So should i try IC Diamond? and what thermal pads size i need to replace the CPU and GPU thermal pads because i don't know where to start with those
I will buy phobya 7wmk pads for the best performance (yes i know they won't be sticky but i replace thermal pads on desktop GPU's before

So if somebody know the thickness i need for all my components and you wanna help me out for witch thermal paste i have to use let me know!

my room temp ios between 20-30c all the time btw
max temp with fan on 80% in crysis 3 = 87/88c atm and it was 80c with OC before i get 87/88 without the OC

 

When you repaste, did you clean the old out and then reapply?
Have you cleaned up the heatsink and vent too?
The temperature range seems acceptable because the range is 80 to 88C from some users, and make sure the bottom of your laptop has good amount of opening to surrounding air.

 

ofcourse i did clean it
and i also cleaned the fans yes
but it was 80c before with OC and now is 88c without OC
and still any advice for the thickness for the thermal pads?

 

There are 0.5mm ones available.
Thermal Pad - 0.5mm | Page 1 | Sort By: Product Title A-Z - FrozenCPU.com

Try with cooler boost on and find out what the max temperature is.

 

is 0.5mm all i need for ram, VRM etc? or do i also need other sizes

 

OK
Your problem first and formost, this laptop is trying to cool a GPU and a CPU using a single fan. Miracles cannot be expected as the cooling system is already underspecced.
The GELID Extreme paste is the most thermally conductive thermal paste available at the moment (it is the same OEM as the Phobya HeGrease Extreme), however, your issue seems to be thermal paste reliability due to your symptom of "rising temperatures", assuming this cannot be accounted for with altering ambient temps. This tells me that your heatsink has poor mounting contact with the components as neither the NT-H1 nor the GELID Extreme is stable when bridging large gaps. When you removed the cooler, what did the Thermal Paste pattern spread look like on the CPU and GPU dies?

Therefore, provided my assumptions are correct, you should try looking in to using IC Diamond for the GPU and CPU (whichever had the poorer contact) and the GELID for the one with better contact. If you are trying to bridge a <0.5mm gap, then IC Diamond is superior to the Phobya thermal pads of similar thickness due to better wettability. With Thermal pads, I usually just purchase selections of .5mm, 1mm and 1.5mm just in case because there can be variances even among the same manufacturer.

 

there is almost no gap on the CPU die but on GPU there are some empty spots indeed so i guess i need IC diamond on the GPU
atm i got 0.5mm on the ram of the GPU and 1mm on the CPU vrm what works perfect.
Gelid VS noctua on GPU...i get better temps with the noctua paste no matter what even with a thin layer of noctua i get petter results gelid get around 87/88 and noctua 85/87 wit a small 50mhz OC but it's not close to the 80c with 1Ghz OC i had

 

It is also advisable to put thermal paste in the bridge between CPU GPU instead of the pad that is there.

Also keep in mind ambient temps as it was mentioned. They severely increase your overall temps if left unnoticed. 88C with 80% fan speed is not unheard off, it depends if you are 100% taxing both CPU and GPU. Even games that only tax it to 95% will see a dramatic drop in frames.

I would also recommend a laptop cooler. I use Cooler MAster U2 and fan speed arund 75% with temps on the 71-78C range for GPU and 80s for CPU when gaming for hours. Only games that fully tax my system do I get 81-84 C (usually playing 4k at max settings haha.

 

problem is...the cpu won't get that hot 70-80 or on rare times max 85c with all cores on 3,35Ghz (unlocked bios) so idk why all of the sudden the GPU get more hot then before there is no real room temp change since it always be around 20/30c

 

Do you play with vsync on? Depending on the game it stresses the GPU more. Use tools to monitor CPU/GPU usage% as well as clocks and temps. You will see how a slight drop in utilization helps a lot with temps. Not all games tax the GPU in the same manner despite being 100% utilization. Different resources cause different impact.

Also if your ambient temp is usually 24 but now it's 27 or 28, you will see a change in temps too. So different games and different ambien temps can be culprit! also remember to keep fans clean with compressed air! A good repaste lasts years, not months so it's usually the game, the dust or the ambient temp, or a combination of those that will tax your system much harder than other games.

 

For the pads use 0.5mm all around and then a good thermal paste application for best performance.

 

i'm not gonna play with v-sync and as a real gamer you probs understand why.
i rather then limit the fps in MSI afterburner
anyway, noctua have a bad habit to dry up faster under higher temps overall and don't go that well with copper.
The proof is on my desktop that use a noctua cooler but no copper part will be found there and it last alot longer

 

IC Diamond would do the trick?

 

The 3M one works well, and add IC diamond for the CPU and GPU.
Notebook cooler will also bring in more airflow to keep the temperature down further.

 

Yes, also go for thermal pads that easier to apply rather than super high performance since they are not what matter, just make sure they are decent like phobya 5w/mk.

You replace them with 0.5mm to get the core as close to the heatsink as possible.

 

Any tips how to apply IC Diamond i hear alot of users on forums says that IC Diamond is really thick thermal pasta some ppl also say lay it hot water etc and since this will be the first time i will use IC Diamond i need some tips
Or just do the old fashion way of the line or dot?

 

Line for the CPU, the GPU I use a slightly elongated blob and cheat with tiny bits (I do mean tiny) of paste in the corner to perfect the coverage and not make it too thick. The relatively low pressure of the notebook heatsinks does make it a little tricky.

 

now about something else
CPU, GPU and PSU upgrading options
I saw the haswell refresh is cooler then the old haswell could i upgrade my CPU to a haswell refresh (unlocked bios)
GTX 880m is possible
and any 240w psu without modding ?

 

Here's a good how to by IC Diamond Application

 

As far as PSUs go, I think you are stuck with the 180W included, because the notebook was power limited to 180w from the PSU and additional power comes from your battery. Unless they changed this at some point, it made higher power PSUs practically useless.

GTX880m is supposed to be a 780m with higher clocks so it should work without issues. If the new haswell refresh use the same socket then they should be compatible.

 

about thermal pads is this any good?
Thermal PAD B 0,5mm - (75x50mm)

 

It may work, but not too much confidence there because based on the tradition of MSI in the past they did not do that.
The processor microcode may be limited to handle just one generation of processors only but not next generation.
We won't know until we actually try it.

 

i might buy a new cpu then just a i3 or i5 for testing sake

 

Thermal PAD B 0,5mm - (75x50mm) is this thermal pad any good?

 

That should do.
