applying termal paste

hi everybody,

it is the time for me to apply a new termal paste to my hp pavilion notebook.
i want to apply it,but i am not confident that i might damage the system.what things should i worry or be sensitive about applying termal paste.

also if you want to help me more you can write steps how to apply termal paste.

I myself,have never opened my laptop before and i know that laptop's chipset is sensitive and complicating.

so how should i apply a termal paste.(was it thermal )

tell this as you are telling it to a idiot because i have never opened my laptop before.

thanks if you help

 

You might want to call a local authorized HP repair facility and let them do it. There is a lot of things that can go wrong removing ribbon cables, wireless cards, etc. They probably will charge for 1 hour labor about $50-$75.

 

oh god.how many parts should i remove just to reach to bloody cpu and gpu ?

also thanks for your fast answer

 

Here are some instructions

But.. In most cases, getting to your CPU will be much harder than applying thermal paste.

Not sure if this is your notebook, but it will give you an idea of whats in store;

Do it yourself. It is really easy. You could slather it all over the inside of your computer and it would cause no harm unless you use arctic silver 5 which has metal in it. 95% of thermal pastes are 100% safe and it is really easy to be careful with a metal based thermal paste. Even if you get it anywhere it cleans out easily with rubbing alcohol.

1. Use a screw driver to remove the cover to access the heatsink.
2. Use a screw driver to remove the heatsink.
3. Use alcohol and a cotton ball to clean the old residue from the chip and the heatsink.
4. Apply thermal paste to the chip's die.
5. Use a screw driver to put on heatsink.
6. Use a screw driver to put on the cover to access the heatsink.

Much easier, better, and cheaper than paying a large chunk of change to some buffoon.

 

Some computers do not have an easy access panel to the CPU, mine is one of them I just upgraded my cpu for my Toshiba Qosmio and had to completely disassemble and flip over the mobo to get to the cpu.

I have an HP pavillion dv9000 also and there is no access panel to the cpu on it either, just to ram and hard drives.

 

oh,it seems hard but i know how to fix things and i have ability.

i can clean the cpu with alcohol of course but what will happen if it is spilled to onether parts.also when i apply the thermal paste to the surface how amount of thermal paste should i apply.people say that it causes overheating if you apply it too much.

 

also i am planing to apply the termal paste called GC-Extreme by gelid.

it tells that it matters 18C when you apply it

well it sound impossible but i will try of course.

people say artic silver 5 but this paste has won awards.

i will try and post the results.

 

If you spill alcohol it doesn't matter. Get the highest concentration you can. Make sure you use 90% or higher and it will evaporate quickly. You really shouldn't be spilling it anyway. Make sure the cotton is damp but not soggy.

Too much thermal paste isn't going to hurt because it will just be pushed out to the sides. Apply a grain of rice sized amount. That is quite a bit more than enough. There just has ot be enough to cover the die with a very thin layer. You can check to see if you did it right.

 

Just make sure you have a large clean work area and by all means do not force anything, sometimes those ribbon cable connectors can be stubborn and can break if you are not careful. If you break one of those little plastic connectors you probably will need to replace the entire mobo.

 

thanks a lot! i really want to try it.i am sure that i will be succesfull at it.

i am going to post some pictures if i am succesfull to make a guide about "how to apply a termal paste" then i will test the termal paste

 

See, this is why I'm willing to just pay people to do stuff like this for me. It's the "Hey, it's really easy, but if you break this little plastic part you'll have to replace the motherboard" sentence - i mean, do I want to risk that, or just pay an expert for an hour of labor?

 

It's like driving a car. It is very easy to do but if you mess up you can die. People get scared of touching their computers way too easily.

 

Get at least 90% alcohol, I usually go for 99%. It evaporates pretty quick.

AS5 is no longer the champ for pastes. Stick with Artic Cooling, OCZ, or Tuniq, but in the end they are all pretty similar. Follow the instructions on how to dismantle your laptop from HP. I know Dell has documents online for this, not sure about HP.

The best way to apply paste:
1. Clean cpu and heatsink with alcohol
2. Apply paste on cpu/heatsink
3. Wipe paste away from both cpu/heatsink with dry q-tip until no longer visible
4. Re-apply paste on CPU about the size of grain of rice. Have it parallel to the cpu die.
5. Mount heatsink

Note: Make sure you wash your hands and that they are lint free when working. Also make sure you are grounded, you don't want to zap your mobo while working.

 

It's important to note that you'll want to use IPA that is more than 90% pure, and avoid using cotton balls or Q-Tips as they leave fibers behind. You'll want to use a coffee filter instead.

 

Just like me and others have said about the alcohol. About the cotton I disagree. The fibers are easy to see and if any are there they are easy to remove with the cotton ball, your fingers, or by blowing them when it is dry.

One thing I forgot to add is that even after rubbing the heatsink and core with alcohol, there is still residue there. This removes easily with a clean dry cotton ball.

 

I use my wife's Make-up sponges... they rock for cleaning CPU's

Though they also rock at making your wife horribly mad at you for ruining her cosmetic supplies So use at your own risk

 

Cotton balls, because of their fiberous nature, will scratch the IHS which is a no-no. They are especially notorious for doing so on copper based heat sinks.

ROFL! There's nothing worse than getting wife aggro and losing faction with her! Be wary Kamin! =D

 

The IHS comes pretty bad as is so I don't think any harm could come to it. This is a laptop forum though and they don't use an IHS. I've been using cotton on bazillions of heatsinks over the past 6 years and have never noticed any scratching. I can't find anything online about it either. I even just tried to scratch a lapped socket 462 copper heatsink and it didn't affect the mirror polish, and I did it as hard as I could. Besides, when I mean wiping it off with a clean dry cotton ball, I mean very lightly.

 

Does anyone know how difficult it is to access the CPU of my Latitude E6400? By reading this thread I'm tempted to re-sink the heatsink using my arctic cooling MX-2 I use for my desktop CPU.
