Done that! many Thanks for your help.
 
Here, Arctic MX4 is pr'lly the most popular pick, due to the low price (~3.5 euros for 4g)

Also the thermal grizzly paste is good but not as needed if you don't have like an i9 extreme that thermal paste you ordered should just do it 

Np there are many people who could help 

Thanks..guys i have a lot to ask please help me to build up my pc..
     Thank you..?

For cpu yes I would recommend the thermal grizzly for max performance but it's up to you 

It depends on the paste and if any solvents have been evaporated. Even then, it can be reintroduced and remixed. That being said, it's likely impractical compared to just buying a new tube of paste.

Yes 100%

Just put a small penny sized or pea sized glob on the CPU and install, no need to spread.

If you're using it on the cpu, sure. 

I would never recommend going without thermal paste you should buy it. They are around 5 bucks no excuse to not get one it will help you majorly 

Yes but terrible temps, just order some thermal paste from amazon. Or you can find a local PC shop and see if they got any thermal paste for sale.

Work? Maybe. 
 
Work in a way that is usable? No. 
 
You need thermal paste (pre-applied or self-applied) between the cooler of the CPU and the CPU. 
 
GPUs come with thermal paste.

Specs? Why don't you have thermal paste?
Without thermal paste, cooling would be much worse and the cpu would likely throttle if not shut down if it gets too hot.
 
Moved to Air Cooling.

Yes 450w is sufficient, 550w if you want to have breathing room for future upgrades.
 
What is your budget and local of purchase? over all build quality and safety features is more important to be concerned about than wattage these days.

Is that just for the power supply or everything?
