In the hot season, you need to constantly monitor the temperature of the processor.
If the sensor readings become higher than 50 degrees Celsius without load, that is, without the use of powerful applications, mainly games, then you need to carefully look at the cooling of the processor.
First you need to check the cooler speed. If it spins at a speed of less than 3000 rpm (RPM), then, therefore, it needs to be changed. But if the rotation speed is normal, then what is the reason that the CPU heats up to such high temperatures?
Many users of their computers immediately go to the market to buy a new cooler for the processor. But why go and replace a fully working one with a new analogue? Most likely, you need to look closely at what is happening between the heatsink and the processor itself. As a rule, a white ointment is always applied between the CPU and the cooler radiator mesh. This is thermal grease.
After removing the radiator, you need to carefully look at the thermal grease itself. After many years of work, it tends to vaporize its active chemical elements of heat transfer. As a result, it hardens and, accordingly, no longer passes heat through itself onto the radiator grid of the cooler.
This raises the question - how to change thermal grease?
Step 1. First you need to purchase it. It is sold at any computer store. Sold in tubes and syringes. The difference is that there is more ointment in the tubes than in the syringes. But with a syringe, applying to the surface of the processor does not cause any difficulties.
How to change thermal grease. Step 2. After the purchase, you want to change it yourself and extend the life of the processor within the normal temperatures for it. How to change it all the same? First, you need to clean the surface of the processor and heatsink from the old layer of ointment. To do this, take a cloth and erase the old composition from the surface of the CPU and the radiator mesh. After you erase the old layer, you need to degrease the surface with gasoline. This is the end of the cleaning.
How to change thermal grease. Step 3. So, the processor and heatsink are cleaned of the old layer. Now we turn to applying a new composition to the CPU. If you purchased a tube, then how to replace the thermal paste, not knowing how much it needs to be applied?
Take the tube and apply a drop to the top of the processor. Now this drop needs to be smeared on the surface so that the surface of the CPU is completely in this substance. To do this, take a piece of paper and gently spread. The layer should look by eye no more than 1 millimeter. After the layer is applied, you can put in place the radiator grid with a cooler.
How to change thermal grease. Step 4. If you purchased a syringe, then a drop of paste is much easier to apply. Apply 2 grams of the substance and smear this drop with a piece of paper on the surface of the processor. Then you can safely put on a radiator mesh.
Please note that everything must be screwed back in very carefully and correctly. If you fix it loosely, and during operation the cooler will shake, then such fluctuations can cause significant damage to the mount and the part itself. Loud noise may also occur. Bolts must be screwed in carefully, without breaking the socket for screws. Of course, you don’t really need to wave a screwdriver so as not to spoil other devices.
After this paste replacement procedure, it is necessary to check the temperature of the CPU. Turn on the computer and go into BIOS by pressing the Del button on the keyboard. Go to the CPU information section and wait 5 minutes. The temperature should not rise above 50 degrees Celsius, due to the correct application of a new ointment on the CPU.
When buying a new cooler, if you do not want to apply thermal grease, pay attention to the models on which a layer of this ointment is already applied. You just need to clean the upper part of the processor from the old layer of paste and put a cooler with a radiator.
I hope the article helped you, and you understood how to change thermal grease.
