Isopropyl Alcohol - When you need to remove stickers or clean anywhere on your PC that cannot be exposed to moisture, isopropyl alcohol is perfect. The potent liquid dries without leaving residue and dissolves even the peskiest buildups of grime.
Yes, you use 90+ isopropyl alcohol and a Qtip to gently clean that off the CPU. However, if you placed that CPU into the motherboard socket like that, you may have a bigger problem than only paste on the processor pads.
Warm water and mild soap: In the absence of rubbing alcohol, warm water and mild soap can be used to clean thermal paste residue. Create a solution of warm water and a small amount of mild dish soap. Dampen a cloth or cotton swab with the solution and gently wipe away the thermal paste residue.
70% IPA is extremely standard for cleaning electronics; the combination of water and IPA is more effective than straight or high purity IPA. There's no way the IPA would damage the board or socket.
Thermal Paste - A silvery-gray substance that you apply to a processor before installing a cooling solution. It allows for an efficient transfer of heat from the IHS of the processor to the base plate or water block of the CPU cooler that is designed to dissipate that heat.
Water cooling, also called liquid cooling, is a method used to lower the temperature of computer processor units (CPUs), and sometimes graphics processor units (GPUs). This process uses water rather than air as the cooling medium because water can conduct heat about 30 times faster than air.
Premade coolants are popular liquids to use in a PC liquid cooling system, and rightly so. They are made specifically for liquid cooling, meaning they are not corrosive or microbiologically unsafe.
However, it is important to note that only alcohol with a grade of 90% or more should be employed on circuit boards and other internal electronics. Lower-grade alcohol contains too much water to be safe.
You need a special kind of alcohol, commonly known as “rubbing alcohol”. Getting a bit technical, you should look for alcohol with more than 90% concentration.
Isopropyl alcohol used to clean PCBs should be 90% grade or better. A lower grade is not safe for electronics.
If you don't have access to rubbing alcohol or isopropyl alcohol, you can pick up a bottle of Grain alcohol from your local liquor store.
Hand sanitizer does not make a very effective cleaner for your CPU, in fact it can actually cause a bit of damage because of the water contents. Fortunately, there are other options that are both affordable and easy to get hold of.
Simply put, using water to clean off thermal paste is never a good idea. It won't work as water won't be able to dissolve thermal paste, plus, it would put your computer at the risk of permanent damage. Instead, you should use high-concentration alcohol, preferably 99% alcohol/isopropyl, for this purpose.
While some sources suggest its potential for cleaning, its effectiveness and safety are questionable. The presence of corrosive components in some formulations of hydrogen peroxide may damage the delicate thermal interface materials or the components of a computer.
Glass cleaner is not recommended for cleaning electronics like laptops and flat-screen TVs due to chemicals that can damage anti-glare and anti-static coatings. Damage from glass cleaners often appears gradually as a yellow tint or fogging on the screen and can make the screen more brittle.
According to Dr. Vijay Iyer, Professor of Chemical and Biological Engineering at Rutgers University, "70% isopropyl alcohol should be safe for most CPUs." He went on to say that if there is any residue left on the CPU after cleaning, it can be removed with a bit of water.
Another potential substitute for thermal paste is thermal gel. It's a dense, grease-like fluid. Unlike thermal pad, thermal gel is a fluid and can fill in all the micro air bubbles between the two components — acting as a good gap-filler. Plus, being a dense grease-like material, it doesn't drip or spill out.
Step 3: Cleaning the CPU
1 - Dip a paper towel into the isopropyl alcohol (90% or 90%+). 2 - Carefully remove the old paste. 3 - wipe the processor's edges, with cotton swab soaked in isopropyl alcohol, to remove remaining old paste. 4 - Remove the paste on the load plate as well.
Even though you may think the higher concentration is more effective, experts say 70% is actually better for disinfecting. It has more water, which helps it to dissolve more slowly, penetrate cells, and kill bacteria. The disinfecting power of rubbing alcohol drops at concentrations higher than 80%-85%.
If necessary, use a mild cleaning solution such as isopropyl alcohol solution (DO NOT USE ethyl alcohol) for difficult spills or messes. This will also disinfect the surface. Note: Always spray or moisten the cloth, not the laptop. You can use a can of compressed air to blow the dust and debris from your keyboard.
Isopropyl alcohol, also called rubbing alcohol, is safe to use just about anywhere on your machine, even the LCD screen. In fact, this is what they use in factories to clean computers before they are shipped out.

Today, water cooling is commonly used in gaming PCs, workstations, and other high-performance computing setups where advanced cooling is crucial.
