How to remove MSI GX640 fan?

Hi,

I've bought some thermal paste (Artic MX-4) and I don't know how to put it on my laptop... I can't remove the fan!!!

At first I removed the pannel, I removed the fan's screws but it seems like the fan is attached to the whole structure. So I removed ALL the screws and tried to remove the structure... but it was very hard and I saw some glue peeling off so I backed off..

My laptop seems now a bit shaky (next to the audio wholes) and I fear I've done something irregular. It's not so bad so I suppose it's ok... Now, how on earth do I remove the fan?!?!

And is it the right place to apply thermal paste?

Omg... HELP.

P.S. : I wanted to put thermal paste so that I could overclock enough to play Starcraft II with my new 26 inches screen on ultra settings. I run mine at 700/100 when on Zalman cooler.

P.S. II : sorry for double posting but this one is more detailled and people on GX640 owners thread don't answer!

 

You have to remove the heatsink. Did you unscrew the 3 screws on the CPU, 2 on the NB and the 4 on the graphics card?

Then you have to slide it up at an angle towards the DVD drive. Pull up on the end of the CPU and graphics heatsink to break the seal of the old paste.

 

I'm trying to remove the heatsink but it seems stuck on the structure...

Ok, I've put it on paint.

I'm not sure I understand what you said niff... I have to break something?

Is the CPU (under the heatsink) the only place where I should put the thermal paste? Where is the GPU?

Sorry; It's my first time digging into hardware business

 

Your "And these 2 (D)" is wrong

Directly below your fan, above the RAM, where the heat pipes are parallel, there is a bracket with 2 screws.

 

Thanks! I'll try it tommorow. After unscrewing these 2, is there anything I should know?

1. --> should I put the thermal paste on the GPU, on the CPU or both?
2. --> should I remove the previous paste and how?

 

Yeah, you should read some guide about repasting (I sincerely believe there are tons of them if you just search for it). Usually everything is explained quite thoroughly: Why to change the thermal paste, how it works, what to do and what NOT to do when repasting CPU and/or GPU.

Meanwhile, you're doing it from the other end: firstly you buy the paste, open up the notebook and then start questioning.

Oh, and old paste can be cleaned with alcohol and some soft tissue.

 

Hey,

Today is the big day! I'll try again to open my laptop. Well one question still remains :

In the specific case of the MSI GX640, should I put thermal paste a) on the CPU b) on the GPU c) on both?

 

Hep,

I finally changed the thermal paste. I removed the original one on both my GPU and CPU to put a lighter coat of arctic 4.

My temps dropped a bit (from 50-52 to 45-48).

Maybe I'll try something else to reduce them (such as putting these "pads" I've seen a lot in heat threads).

Thanks everyone!

 

The thermal paste is better than pads...

If I were you, I would not try any copper shim mods, it generally changes the way the GPU levels and your vRAM wont stay cool unless you get new pads for that too.

If you want an even simpler mod that no one has tried before, try this:
-buy some copper foil, the thickest you can get while still calling it foil on ebay.
-buy some thermal tape (budget so far is like 4$ )
-if you look straight down at the bottom of your laptop by the fan outlet and radiator, you will see about 3mm of space between the end of the aluminum radiator fins
-take out your heatsink, cut the foil (with scissors, but clean it afterwards) and tape it to your radiator. make some fins to fill the gap. have them extend in between the old fins, or outwards through the vent. also may want to cover both sides of the fan shroud.

pretty much an arts & crafts project. I'm going to try it soon, I'm sure it will help temps even more.

 

Cool! Keep me posted please. I don't want to spend 10 years on this right now but as soon as the university session ends; I'll try it.
