Use your Vodkar and drink it, after that, use alcohol or isopropyl alcohol to clean both CPU and Cooler.
Don't use your finger to apply the TIM because this have grease and damage the TIM as soon as you touch it, use and old credit or debit card (clean it too with alcohol before use) to cover all cooler, then install it on CPU.
U should NEVER use a credit card to rub therrmal paste. The only and best way to do it is by putting a pea size dot in the center. The credit card method will fully spread the paste around. But once the cpu gets hot it will melt and fall off the cpu onto the mobo.
