The most frustrating proublem

[Guest]

Do i need to give my case a negative preassure or a positive? Most videos are saying positive, while guides are saying negative. Ps. Is there any ways to completely cover the cpu with a thermal paste?

If ALL of your intake fans have a decent quality dust filter in fronts of them then you definitely want slightly positive case pressure. As in, you want slightly more intake than exhaust fans (assuming all your fans are the same). Having more exhaust fans (negative pressure) will result in air being drawn into the case from places other than the dust filters, resulting in a lot more dust inside the case.

Some cheaper cases don't have dust filers on the intake anyway, making it irrelevant. Also, in my experience, even with positive pressure and dust filters you'll still need to dust your PC from time to time anyway. So in the end of the day it doesn't really make that much difference.

RE Thermal paste, usually you put a spot in the middle and the pressure of the cooler spreads it out. Just follow a guide on that. Why would you want to "completely cover"? Pick someone who seems to know what they're talking about and follow their technique. In the end of the day as long as you don't do a terrible job (generally meaning too little, or much to much thermal paste), your application technique is hardly going to make any difference anyway.

The square cpu you see isn't actually the cpu. It's like a heatsink lid. The actual cpu is just a strip down the center, covers less than half of the lid, lots of room on the sides, empty air inside. So you don't need to cover the entire cpu, as long as the center strip and spreading outwards is covered. A nice, big, round splurge right in the center is good, as long as it's super thin and even. Too much is just as bad as not enough.
