Cómo aplicar pasta térmica

Qué necesitas

  1. Cómo aplicar pasta térmica, Visión general: paso 1, imagen 1 de 1
    • La pasta térmica es responsable de conducir el calor desde el procesador hasta el disipador. Ensamblar una computadora sin aplicar pasta termal puede causar un recalentamiento en el procesador, provocando daños permanentes.

    • Antes de aplicar una nueva capa de pasta termal, primero deberás eliminar cualquier pasta térmica antigua de la superficie del procesador y del disipador de calor.

    the best way to clean a CPU or a GPU is to use a spudger and ISOPROPYL its an alcohol that dries fast




    What is isopropyl

    Ronald - Contestar

    Please don’t use isopropyl alcohol to clean wounds—it is actually detrimental to cellular healing. Rinsing copiously with normal saline or clean water is much better.

    Yoron - Contestar

    If you cam here from the PS 4 fan replacement page, I highly recommend the “pea” method instead.

    • Use el extremo plano de un spudger (herramienta) para raspar la mayor cantidad de pasta térmica solificada del núcleo o núcleos de cobre del disipador.

    Personally, I used a BD Alcohol Swab (Isopropyl Alcohol 70%) to wipe down the heatsink, and didn’t even bother with using the spudger to scrape off the old thermal paste. This ensured a quicker and complete removal of the old paste.

    MarkyMark - Contestar

    Dont remove the thermal paste with the spudger. You might scratch the heatsink. Its not a great deal as the new paste will fill those scratches. But still better to not scratch it in the first place.

    sebastian.wittl - Contestar

    I think it's best to begin the cleaning process with a completely dry coffee filter or paper towel first, otherwise the paste just gets smeared around. Once the bulk is removed, then clean with IPA and a filter/towel until it comes clean.

    • Después de raspar la pasta termal solidificada, aun quedara un residuo en el núcleo o núcleos de cobre.

  4. Cómo aplicar pasta térmica: paso 4, imagen 1 de 2 Cómo aplicar pasta térmica: paso 4, imagen 2 de 2
    • Utiliza un filtro de café o un paño sin pelusa y un poco de alcohol isopropílico (también conocido como IPA, de concentración 90% o superior) para limpiar los residuos de pasta térmica de la superficie de contacto térmico de su disipador de calor.

    • En lugar de IPA, puedes también usar un agente de limpieza especial, como el limpiador de material térmico ArctiClean.

    • Una vez que la superficie esté limpia, usa una parte limpia de un filtro de café o un paño y un poco más de IPA para eliminar los aceites y preparar la superficie.

    • No toques ni el chip ni el disipador de calor, ni permitas que entre polvo o suciedad sobre ellos. Incluso una huella digital puede ser un obstáculo importante para la transferencia térmica en un chip

    • Permite que el (los) disipador (es) de calor se seque(n) por completo.

    Alcohol is fine, I use it and it not only does a better job but is far less toxic. That stuff causes all kinds of cellular damage to you.

    South30 - Contestar

    You dont put the instruction on whether we have to put the new thermal paste back again or not? Do we have to, right?? thanks

    Eddy Setiawan - Contestar

    If you use ~91% isopropyl alcohol to clean, it will evaporate rapidly and leave no residue (assuming you wiped away anything that wasn't the alcohol or water in the 91% solution you just used). Your prep is done, there.

    Mr. Porter - Contestar

    I really wish the author would have stated what IPA meant. I had to Google it. The only information given, as stated, is “a.k.a IPA, 90% concentration or greater), giving no clear statement advising us that IPA is in fact isopropanol.

    Isopropyl alcohol (2-propanol) is also known as isopropanol or IPA.

    MarkyMark - Contestar

    Why is it stated that the concentration of alcohol have to be 90% or greater?

    MarkyMark - Contestar

    The other 10% is water. I don’t know if it has to do with the evaporation or protecting the electronics.

    Paul van Ekeren -

    Does it ABSOLUTELY need to be 90% or greater?

    DigiVore - Contestar

    A friend told be about using lighter fluid a decade ago and I’ve been using that to get thermal paste off ever since. It’s super effective, only requires a little bit and it still evaporates. I highly recommend using that over alcohol unless you really like scrubbing. With lighter fluid it just sweeps it right off.

  5. Cómo aplicar pasta térmica: paso 5, imagen 1 de 1
    • Use el extremo plano de un spudger de plástico para eliminar cualquier pasta térmica solidificada de la superficie de los procesadores

    • No use ningún objeto de metal para este procedimiento. Tenga cuidado de no romper ningún componente en la superficie del procesador, ni de perder ningún compuesto térmico en ninguno de los componentes (las pastas conductoras podrían causar problemas).

    you can also use a junk credit card or similar, or a plastic spoon

    Gaspard Leon - Contestar

    Obsolete business cards are good too.

    How to remove thermal paste remover solution that has got trapped under the cpu chip?

    I have some liquid thermal paste remover that has got trapped under the cpu chip that I want to make sure it is completely removed.

    Osama Maddani - Contestar

  6. Cómo aplicar pasta térmica: paso 6, imagen 1 de 2 Cómo aplicar pasta térmica: paso 6, imagen 2 de 2
    • De nuevo, usa un filtro de café o un paño sin pelusa y un poco de IPA o ArctiClean Thermal Material Remover para limpiar cualquier residuo de pasta térmica de la superficie del procesador.

    • Usa un trozo limpio de un filtro de café o paño para eliminar cualquier aceite residual y preparar la superficie

    • Permite que el (los) procesador (es) se sequen por completo.

    Be aware that this picture may not represent how your processor looks. Most of the PS3 fats have a heat spreader over the die. The pictures above show the processors without the heat spreaders.

    Jason Pirok - Contestar

    @Jason Pirok yes I realised! Do we remove the heat spreader of the die tho?

    JB Tan - Contestar

    Do NOT attempt to remove the heat spreader unless you have the proper materials to 'rebuild' it (which you probably don't). Just clean off the surface areas that you can see and you'll be just fine.

    Lance - Contestar

  7. Cómo aplicar pasta térmica: paso 7, imagen 1 de 1
    • Para aplicar pasta térmica nueva, use el método de aplicación recomendado para su tipo de procesador específico: línea vertical, línea horizontal, punto medio o extensión de superficie. Tenga en cuenta que la dispersión superficial tiene el potencial de atrapar burbujas de aire.

    • Si está utilizando el método de dispersión de superficie:

    • Envuelva la punta de su dedo índice con un pedazo de plástico (como una bolsa de sándwich o una envoltura de plástico).

    • Dispense una cantidad muy pequeña de pasta térmica sobre el(los) núcleo(s) del procesador.

    • Utilice su dedo para frotar suavemente la pasta térmica sobre todo el núcleo del procesador(es).

    • Si accidentalmente aplica una pequeña cantidad de pasta térmica en la superficie verde del procesador, no causará ningún daño.

    • El procesador está listo para la instalación del disipador de calor.

    • No es necesario aplicar ninguna pasta térmica en el disipador de calor, aunque Arctic Silver da instrucciones de "teñir" el disipador de calor para reducir el tiempo de rotura del compuesto térmico.

    Some people apply a little dab in the center, and then install the heat sink. It spreads it evenly unlike a finger, and is much cleaner. I use this method on cpus with a heat spreader, and ones with the bare die. You can also apply a dab, and use a razor blade to spread it evenly too. The finger method tends to leave air bubbles, and doesn't spread evenly. I use Arctic Silver 5, but sometimes have to spread it with a blade as it is so thick. I hear that Arctic Cooling MX-3 is suppose to be better. I hate that AS5 can be electrically conductive. It makes me nervous that i will short something out. I hate AS5 200 hour curing time. MX-3 is claimed to not need any curing time, and not electrically conductive, So if you apply the amount that Apple did with the 2006 MacBooks, you will still have a working computer. If apple applied AS5, like they applied thermal paste in 2006, I bet the laptop would be DOA.

    Just my little thoughts on thermal compound.

    Nicholas Ouimet - Contestar

    the dab in the center is know as a pea. See for recommendations on applying the paste to Intel chips, either a pea or a line depending on CPU.

    Swapping out the heatsink on my 15" MBP seemed to go fine. The instructions were clear and easy to follow. My computer had been shutting down immediately and was unusable. I did some research and it sounded like the heatsink was the problem. After reassembling the computer, when I started it up, there was a little puff of smoke from the back left of the keyboard... and... no screen backlight came on.

    The repair solved the problem of my computer constantly shutting down, but now I can only see my screen if I shine a bright light on it.

    Does anyone know what could have happened? If the thermal compound was touching some little wire or something, could it have caused a short?

    Did you use Arctic Silver? It's possible something shorted, but I'm leaning more toward a lose display cable. Try re-seating the cable.

    Nicholas Ouimet - Contestar

    If it's a laptop, it IS a smear spread, not a pea or line. The link says so.

    Probably because the laptop pipe mounting pressure is not very high and won't spread it as much.

    Example, the 15" A1226 Macbook Pro has only 5 screws and 3 chips it touches, and they aren't very close to the cores.

    beachfitrob - Contestar

    I've replaced the paste on many chips over the years. In my experience, the wiping method tends to leave air pockets unless you're extremely careful and spread the compound very smoothly. It's a lot easier, and more effective imho, to use the pea or line method on ANY chip. The pressure of a laptop heat sync is quite sufficient to spread the compound evenly.

    I do recommend using only compounds which are 100% non-conductive. I also recommend buying a compound with the longest lifespan, unless you are sure you want to go through this procedure every couple of years.

    MoldyOldyComputerGuy -

    I happen to agree with moldyoldy - use a non-conductive grease. The likelihood of the "heat sink" ( its actually a heat pipe) failing is pretty darn low. The crap heatsink compound is more likely the problem. Recently I dropped my early 2013 MBP retina. Long story. Anyway - for the next few days- machine acted odd - reported USB devices pulling too much current- then it started crashing, and finally started locking up- wouldn't boot until it cooled.I was concerned about having damaged the heat pipe, so pulled it off. The compound was dry and crumbly. Odds are the drop cracked this dry gunk and affected the heat transfer. So I cleaned off the old gunk ( denatured ethanol ) and reassembled using old school white heatsink grease. Grease. As in oily as !&&*, like it has been for the 45 years I've used the stuff. Currently, machine idles at about 110F, and never gets above 215F with all eight hyper threads at full bore. The idle temp is 20F lower than it was new. And will never dry out.

    ^ like. I have a similarly misbehaving similar brute and similar skills and resources. I’ll be giving this a try.

    Rib Man -

    With all due respect, I am very skeptical about spreading the thermal paste with your finger, there are a lot of tutorial videos out there on Youtube that provide proof about all the bubble you are going to leave behind that will mess up your heat exchange efficiency

    alfx - Contestar

    This aspect is a bit over-rated as to detail. The amount of thermal paste the Apple factories applies to the processor surfaces is huge, spilling onto the green surfaces of the processors. This can be seen once one removes the heat sink component that sits on the processors. Gobs and gobs of thermal paste abounds everywhere.

    dcelander - Contestar

    I have a MBP retina 15” early 2013 which has got a black sticker covering the chip and revealing only the core, this sticker has got thermal paste stuck under it when i was using the solution on it , and the sticker has got damaged when I cleaned what was under it, my concern that is is it safe to reinstall the heatsink without this sticker, or will the heatsink make contact with the diodes in the chip and short something out ?

    Osama Maddani - Contestar

    Thank you very much!!!! Couldn't have done it without this tutorial:)

    Charles Walton - Contestar

    The Arctic Silver page wasn’t super informative. For 3rd to 9th gen core it suggested vertical line, but on the bottom under “previous gen core” it suggested surface spread for “Core™ i5 Mobile/Lap Top Processors Processors”.

    So I did the “Vertical Line”, the only problem being that the metal surface of the processor is very oblong in my processor and all the example images had square surface, so which way is vertical? I put it along the long side of the core, so it would cover the entire surface, but I’m not sure if it is now a horizontal line.

    Antti Valli - Contestar

    I was once in a pinch for a thermal paste, and needed a lot of it (it was to repair the contact of cooling coils on a 500 liter beer lagering tank. Thermal paste is expensive. It really contains only two important things. Something with high thermal conductivity, and a material that holds that together. The very expensive ones, with silver have not been shown to be superior to ones with less conductive and less expensive material (i.e. copper) as the component that houses them makes that difference negligible according to my reading. I looked up the thermal conductivity of different materials and was surprised to find graphite has nearly as good conductivity as aluminum. Melted some vaseline, added the graphite (free from the local foundry) and it made a dandy paste that worked very well. Chilling rates on the fermentation vessel back to specs! Vaseline would be a poor choice in a heating environment, but with a little creativity you could probably I-fix-this if you don’t bump into any thermal paste.

For heat sinks with a spring on the screws: Wonder why there are springs on the heat sink screws? Do not over tighten them, the springs are there to help you apply the correct amount of pressure on to the CPU and GPU. If you tighten them all the way, it may not be the correct pressure! Leave maybe 1 mm of space, just before the screw stops turning. iFixit forgot to mention this important part, and also in the heat paste guide!!

m3kw - Contestar

This is completely untrue. The holes bored in the heat sinks are in fact a larger diameter than both the threads and the shoulder of the heat sink screws. The screws should be fully tightened (as they were from the factory) to maintain correct pressure against the processors.

Andrew Bookholt -

I have two green lights on my xbox slim ... Should I do all of this to get rid of them? I'm not sure if they are supposed to be green. I bought my wii and remotes from a refurbishing place. I don't have the red ring of death, but I think it is from over heating.

OMG Hi -

Thank you so much for this! Have been struggling for months with CPU diode sensor reporting 262F/128C and CPU dropping to 0.8 Ghz due to Speedstep. Loosened the screws a little and the sensor is back to normal. I cannot thank you enough for this!

Try reheating / reballing the gpu soldering. It worked for me more than 3 times.

If it was a mid 2007/early 2008 Macbook Pro 15”/17”, it is actually a GPU defect. It needs to be replaced with a revised version. In fact, dosdude1 made a video about that. If it’s a late 2008-mid 2010 15”/17” Macbook Pro, it’s actually a problem with a capacitor on the GPU buck converter circuit, it is not a problem with the GPU in these machines (C7771 on the 2008 and 2009 models, C9560 on the 2010 models.) If it’s a early/late 2011 15”/17” Macbook Pro with AMD Radeon HD 6xxxM graphics, it’s a GPU issue that can be fixed using the technique described at

Rupertus -

Actually, Tom's Hardware's guide said not to spread the paste out, but to have a solid line of paste vertically across the longest part of the metal cap and let the heat sink spread it out as it gets tightened. This method supposedly reduces the risk of air bubbles. My only curiousity is with processors that have little resistors or some such things placed around the metal heat cap, should those be pasted as well or not? Dell's processor came completely covered with paste, onto the chips as well, but I'm wondering if I should re-apply to the chips or just to the cap.

Frank - Contestar

Note: This old thread still deserves a reminder: Those are capacitors and the type of paste used is CRITICAL. If it is non conductive (white, pink or any non metallic color) it's Ok if it gets on the capacitors. If the recommended paste is Arctic SILVER or any metal filled paste, do NOT let it get on the capacitors. Your best bet is to apply a slim line of paste along the longest length of the chip and use a credit card as a squeegee to spread the paste into a smooth film. Then apply a small drop to the center (optional). Wetting the surface helps.

Hello to everyone .

They gave me that link due to a recent upgrade i doing to my iMAC late 2013 with Nvidia Gpu 4gb.

I changing processor for a better one. The post is very good as all ifixit posts. For thermal paste i dont think Apple used right one because i have this machine for 2 months maybe 2500 hours at plug and when i opened it the past was already as 20 years old. Also around Nvidia chip there are big sighs of serious overheating means that cooler not doing its job and think most the paste.

For paste can make contacts there is a simple trick to test it before apply.

With Ohm meter spread some amount somewhere and measure the resistance.

The springs at the GPU chipset must screwed tight as it is from factory becareful to not twist them when righting the screws.

The job is not for normal people It needs some skills.Can easily something go wrong.

Also take care big attention to the connectors everywhere...

Thank you very much i hope i gave a little help as i took me too ..
