Thermal paste how long does it last

MadGoat :. It doesn't go 'off' nor does it dry out. And I can bet a heck of a lot of PCs in the world used by 'normal' users don't ever think about it, and have no problems. I say if theres no issues, don't bother! Guest Guest. I replace the TIM when the heatsink comes off, which is when the cpu gets moved, which is pretty often in my house, i am always tinkering, and this new Crosshairs IV s lovely to tinker with!

No hard and fast rule though, just keep regular eye on temps, if they climb above average and its not the hottest day on record, start checking everything! Jul 15, 2, 0 20, Its very simple, if your temperatures are fine then everything is working fine.. If you have dust problems, use dust filters, they are fantastic at keeping your maintainence schedule down, also get one of those hand pump weed sprayers new and use it as portable compressed air, works a treat!

Jan 12, 3, 0 22, But this topic is heavily dependent on the compound in question. For example, many thermal compounds use a dissolved silver compound for its great conductive properties. BUT, Silver does tarnish oxidize and will loose its conductivity over time. On the other hand there are silicone based thermal compounds that will separate and migrate over time and cause air gaps between components. There are many compounds that can be used for a permanent solution and do not migrate or oxidize and many OEMs use these to ensure proper longer term functionality.

Although as i said before, most "enthusiast" marketed compounds are geared towards performance not longevity. Thanks for the replies. The old stock thermal paste was actually poorly applied Thick in some areas and gone in others so I am glad I checked. Thermal paste needs to be reapplied over time as it does go off. But not that often. I went and bought thermal paste for my Dell that was getting exceedingly hot over time the case was even getting hot so I took off the heatsinc to find that there was a tiny amount of thermal compound on the CPU and even then it was literally dust.

I risked ruining my laptop, and will never take that risk again. It DOES appear to dissipate or something, because there was very little left, and none on the touching surfaces.

There are many factors involved in knowing exactly — how long does thermal paste last in the tube. This article will discuss the composition of a thermal paste and, the proper way of storing it to prolong its shelf life. Thermal paste is made out of a polymerizable liquid matrix and some electrically insulating conductive fillers. For this liquid matrix, there are a lot of materials that can be used to make the thermal paste.

While there are a lot of materials that can be used to make a thermal paste, the best thermal pastes for computers are almost made entirely out of liquid metal. However, these contain Gallium which is highly corrosive to aluminum. For the longevity of your thermal paste, it is best to keep it in a cool area. Some might suggest keeping it inside your fridge or freezer but it does not matter.

In fact, it might be more dangerous when you apply it after getting it out of the freezer. The best way to store it is just to put it inside an airtight sealed container like a Ziploc plastic bag. The only places you want to avoid are areas that can be exposed to sunlight or heat such as a drawer near a window.

If you live in a tropical country where the normal room temperature is higher than usual, it should factor in drying up your thermal paste tube as well. With my experience, I keep it inside a drawer where the room is air-conditioned for the most part. Basically, thermal paste is cheap enough and bought by the gram on most occasions so you do not have to worry about storing them as you would just want the right amount in applying it on your CPU.

You also do not want to risk applying the thermal paste on your CPU that is almost dried up as it may have some risk of damaging your CPU. For thermal paste that is still on the tube, it should last around years. Again, I do not recommend keeping or stocking old thermal paste for future use. It is easy to buy another one and it is quite cheap. While it lasts around years, it could also last for a couple of more years as it depends on a lot of factors.

You can find the thermal compounds in any local stores at reasonable prices. Undoubtedly, your CPU price is much higher than a thermal paste, so avoid the risk of not utilizing it. Be aware of using the wrong paste, which can overheat and damage your system. Make sure you choose the right thermal paste for your computer.
