I've took the liberty to re-paste my new laptop with Artic Silver 5 High den on CPU & GPU.

Now, the laptop is about 3 Weeks Old. the stock temps for both on Idle was 41-50c CPU all cores, and 40c GPU, this was probably not necessary since those temps are totally fine. but I am a freak in terms of stocks thermals, they usually bug me so I had to use a brand and optimize the laptop in every possible way. (soon I will be upgrading the cpu with a 3840QM 2.8Ghz - 3.8Ghz to stay on the line with the haswell performances)

just letting know for those who are new into the whole repasting and what not, it will break you're warranty if you upgrade/open the CPU/GPU. I've don't so because the asus warranty isn't useful at all. besides getting them to replace refurbished parts on your laptop, which I dislike a lot I prefer to spend and buy new parts off ebay or a site)


anyway, when I reached the CPU/GPU part. I've started to remove the heatsink, and I noticed the paste they used was literally like gum you find under ur shoes, you can't even remove it regardless with what kind of cleaner you use, so if you are in this process, be careful because the heatsink might not be well attached with the copper, put it on a flat surface and clean it from there with a credit card or butter knife, anything that isn't sharp but sharp enough to remove idealistic sticky surfaces without leaving or scratching anything.

anyway after the cleaning process it took me about 10 minute to clean it to a point where copper becomes shiny as a mirror.

I started to use the artic silver on the cpu, I did a I method , haven't spread it I just pressed the heatsink on top and screwed the screws.

the GPU was sticky when I tried to remove the heatsink from it. the pads they used, they seem really off from where they've put them. I found more around on the card surface instead on the VRAM?? sadly I couldn't find the right pads for it so I just took the pads that melted around the VRAM and spread them with my finger on the vram.

for the GPU process of putting the Artic silver, I've done an X method. (it usually gives a perfect O form without leaking on the sides)

and voila. then of course once done I remounted everything


After 48 Hours of idle / gaming here are my results !
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

GPU: 670MX 3GB
Before:
GPU Idle: 37-45c
Max GPU temp: 72c (Using furmark software)

After:
GPU Idle: 34-37c
Max GPU temp: 67c (Using furmark software)
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

CPU: 3630QM
Before:
CPU Idle temp : 41-50 All cores
CPU Max temp: 84-87 Max on all cores (Using 95 Prime software)

After:
CPU Idle temp : 29-33 All cores (HUGE drop here of temps)
CPU Max temp: 72-82 Max on all cores (Using 95 Prime software)

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

in conclusion, was it worth it? well for myself, yes. if you've done repasting on desktops, a laptop should be fun and much easy imo. the only annoying part is when you FIRST dissemble the laptop, because everything is so sniff and sticky so you get that feeling as if you going to break something lmao) but I can definitely agree that each laptop WILL give different temps regardless of what you use to re-paste. it seems like the fans are more likely to be the ideal upgrading here. my cousin did the same process as I did.

he used the same thermal and got much much less lower heat idles and max tho. I've repasted about 3-4 times to make sure. so if you're lucky you might have the good stuff :p

GPU did kind of drop few temps, but the cpu really got a nice improvement.

I also noticed, after the Repasting the fans turns off more often now, and they don't turn on unless I play a video, or use a heavy metro app


I wanted to put IC diamond, but they were out of stock from my retailer. If anyone tried IC diamond could you perhaps suggest if it's any better?

Hello! I wrote a PM for you about this post. Will be great, if you can make a tutorial video about your upgrading/cleaning/re-pasting.

may i ask at what room temp u had those temps? before and after if any diffrents in your room temp

When I purchased my laptop I had them upgrade my cpu to 3740qm and they said with every upgrade they will repaste not only the cpu but the gpu with ic diamond so I don't really know what my temps would have been and I don't even know what they are now what can I use to check my temps?

Will do as soon I have the time !

room temps were around 19-22 before, and after around 20-22 really I did this all within 2 hours. so temps of the room haven't changed much

Hwinfo 64 (http://www.hwinfo.com/download64.html) this will tell you everything about your hardware

My idle temps are around 20 degrees, with temps currently at 39 degrees after quite a bit of gaming and bout 10 mins of surfing afterwards, (browsing this forum)

BTW i use ic diamond

very impressive !

I assume the diamond does carry its reputation then!

Mate, I seriously cannot believe you until I see the program that you measure your temps and a thermometer measuring the room temperature side by side. There is absolutely no way that in an average room temperature 15-20 degrees, you will have such temps for the CPU, no matter even if you are using IC mega giga diamond.

I could have sworn 32 degrees is freezing temperature but I could be wrong maybe he means Celsius?

My gpu and cpu both have ic diamond but im going to check the temps tomorrow when its hot out and see how well the ic realy works cause I have no ac in my room then ill check them at night and see the difference is.

yes computer temps are always in Celsius

Djask

First, it was celsius, (obviously) and secondly, temps were way under the average room temperatures so yea, i guess my result is invalid. :P

No love for G55VW? T_T

Did same repaste method but with Céramique™ 2.

GPU Idle = 40c
GPU stock max load = 70c
GPU 1200/3000 OCed max load = 80-85c (Depends on game)

My G55 is somewhat the same as yours. I am using Ceramique 2
Room temp: 20-23
CPU idle: 40-45
GPU idle: 35-40
In gaming mode both reach 75-80 with CPU at stock and GPU core +135 and memory +600
I haven't repasted for around half an year now and I think there is some dust inside the fans. So if I use IC Diamond or AS5, clean it thoroughly and do a really good job on the repasting, maybe I can hit idle CPU 35 degrees and teh GPU maybe at 30 at the min and game temps around 70.

I want to repaste and repat my g75, but really dont want to tear the laptop apart just for such a simple thing :(

Well if you want to overclock or force some P-states you will be better off with lower temps :P

It's easier than you think :) just simple caution steps. I am going to make a tutorial soon to dissemble a G75VX, although not any time soon :x

do you have to lift the entire top up to disassemble the g75, cus thats what you have to do in the g46. :/

ggBanks

It's pretty much the same for all models yes. If you want to repaste you have to pretty much disassemble the whole laptop except the display.

my G75vx purchase in march, idle temp 35-42C, while 3 hour gaming (farcry3,sc2,deadSpace3) temp 56c-65C... i never did any Repaste cpu/gpu... so those factory/stock thermal paste (look like glue under shoe from asus is good) . lol i live in malaysia room temp 30C-39C

Yup those temps are totally fine. I had OK temps stock, but I wanted to see how effective the cooling would be with these new G-Series laptop.


Is it me or the G74SX had the best cooling design ever? having those two big fans stacked together made it more effective although by adding the cost of bulky design

What did Asus use for the vram, did they use pads or thermal paste? I want to make sure when I pull this thing apart I have everything I need. Looks like whatever they used has melted and is running down the sides of the chip
