How Extended Does Thermal Paste Last

Normally, thermal pastes can last between two to five years when still in the box. However, this range may differ hanging on the components and the manufacturing. The greatly common kinds of thermal gels are silicone, metal, carbon, and ceramic each with various accomplishments, processes, and strengths.

As a regulation of thumb, non-metallic mixtures manage to endure lengthy in the container. If you like to purchase one, though, it’s not a reasonable suggestion to establish your conclusion on the mixtures’ strength since thermal conductivity is much extra important.

Be convinced you’re purchasing from an original organization, and you are required to examine the expiration duration behind the bottle to know how long it will last. Similarly, be convinced you pack the product in excellent condition, so it won’t run terribly before the expiry duration.

Below are some tips:

  • Be convinced you tightly lock the top after every use.
  • Put the paste away safeguarded from extraordinary hot or cold weather.
  • Arrange it in a closed carton or plastic suitcase.
  • Don’t uncover it to direct sunshine.

What Is Thermal Paste

Thermal paste is a humid material used as a heat-conductive connection point between a central processor and its heatsink. This dealer covers the small air holes between the heat origin and the heatsink, reducing heat transfer and refrigerating impacts.

It takes off by other titles, such as thermal oil, conductive paste, heat sink mixture, CPU oil, and thermal gel. No course what you name it, without nice paste, you will gamble on overheating your CPU, which could endanger your whole system. That’s why it’s significant to realize how long thermal paste lasts while in the box and then once correlated.

How To Know If A Thermal Paste Is Damaged

If you see considerable differences in a thermal paste’s fabric, it’s not available anymore. Thermal pastes are identical to glue. Therefore, if you see them as very tough or too liquid, they may have missed their sticky properties.

Non-smooth, transparent water is also an indication of a poor paste. However, if you pinch out the unstained water and a white or gray mixture leaks, you can yet use it.

How Long Does Thermal Paste Last on the Appliance?

A common thermal paste will last about five years on your CPU or any other chunk. Relying on the temperature, the computer’s refrigerating network, usage, and the mixture’s quality, this quantity can reduce to three years or rise to as much as ten years.

Below is the reason and how these components influence the time.

  • Unnecessary Use

You may want to renovate your thermal paste faster than regular if any of the subsequent problems is real about you. 

  • You have overclocked the computer. 
  • You are a game player and operate graphically mandating games on your computer.
  • You have discovered a climate growth in your computer, particularly in the motherboard region, but you are certain there’s nothing untrue with the fan or cooler. 

All the above techniques make your CPU overrun and extremely heated.

A heated CPU tells a lower lifespan for the conductive oil. That’s why professional game players and computer techies renovate their CPU oil every year. Your usage habit is another determining characteristic influencing the lifespan of your thermal paste. If you use your computer 24/7, be conscious that it won’t satisfy you for more than a year or two.

  • Thermal Paste Quality

If you prioritize rate over accomplishment and deny to donate in a main thermal paste, then you shouldn’t want it to function for more than a maximum of three years. Apart from quality, the components fiddle a significant part here. As a regulation, the more warmth a thermal paste conducts, the quicker it becomes ineffective.

  • Temperature and Surroundings

If you reside in a heated area or occur that you position your PC in a heated room like a mansard, your thermal mixture misses its efficiency more effortlessly. Strive to stabilize your computer’s interior climate by putting in the right fans.

However, just organizing the weather won’t be sufficient. Dust, lint, mud, and dirt also pollute your thermal gel’s properties. Use a can of compressed air to clear your computer’s interior components at least every three months. You can launch a dust filter to avoid further dust aggregation.

  • Excessively Much Paste

Some people manage to correlate excessively much paste, believing that if they use extra, it’ll last longer. However, too much paste on a flake often stays smaller and can turn out to harm your processor.

  • Ingredient Replacement

If it’s because of a system upgrade or restoration, you may conclude to disband your computer. Once you achieve that, however, the thermal paste will not stick, and you will be expected to use it one time again. If your modern CPU reaches with pre-applied thermal paste, you won’t be required to apply it again. Test if you find some silver-like material at the end of your heatsink.

How To Apply Thermal Paste?

Accurate usage of thermal paste enables extending its lifespan on the flake.

Below are the steps:

  • Disassemble your computer with a screwdriver or any equipment you have.
  • Uninstall your CPU fan, heatsink, and the CPU. Relying on the equipment, you may not have to extract the heatsink. Make sure you deal with the CPU with ultimate care since it’s highly sensitive.
  • Saturate a lint-free rag with isopropyl liquor, and then clean it all over the heatsink skin.
  • In case you see hits and holes on either of the surfaces, use nice grain sandpaper to flatten it out.
  • Scrape a small drop, twice the quantity of a rice grain, literally to the middle of your cooler basis.


  • Although some people may tell you to use a pea-sized drip, that will be too sizably since it pours your paste over the CPU fringes and, even poorly, your motherboard. Plus, a large layer hinders warmth transfer instead of upgrading it. Position the heatsink on your CPU and push it gently, so the treatment circulates evenly.
  • Onetime you use the cooler, don’t raise it to know how the paste is allocated. Unless you’ll have to rub out the bond and reiterate the procedure once again.
  • Don’t use a card or another thing to spread the paste since the smallest quantity of anxiety on the cooler will flawlessly do the job. Circulating the fluid through a card generates air bubbles between your devices, which can adversely influence the warmth transfer.
  • Reboot your computer and scan if the fan is operating before you reorganize the case. Be sure your CPU temperature does not move above 40°C with your Hardware Monitor.

How to Expand the Longevity of Thermal Paste

Below are some additional tips to examine when handling the thermal paste:

  • Stock the product based on the producer’s approaches.
  • Be sure you appropriately use adequate paste.
  • Tidy up your computer regularly.
  • Don’t disassemble your computer elements if you don’t know how to.
  • Put in dust filters in your computer case.


How To Use My Old Therma Paste

You may still like to use your old thermal paste instead of buying a new one for one purpose or the other. You may wonder if it’s likely and how you can do so. Unless you detect the main reversal in the color, density, or stickiness of the property, you can still use your old thermal paste.

However, be sure you obey the steps below:

First, pour out a little quantity of the paste on a sheet of paper. This original material is usually a bright liquid that’s no more sticky due to potential air disclosure. Pour until you attain the useful white, silver, or dull material. Then fling the paper away.

Hanging on the packaging, stir the bottle or rip off the pipe, so the subjects will be mixed and constant. Obey the producer protocols to use the thermal oil.


As seen on the above page, how long does thermal paste last, the meaning of thermal paste, if I can still use my old thermal paste, how to expand the longevity of thermal paste, and how long does a thermal paste use to be harmful?
