i need you guys help its my very first time to actually do something like this..apparently my H80i isn't doing its job but it seems to be working fine, so im pretty sure its not faulty. after looking around online i figured out that maybe it isn't seated properly and maybe the thermal paste on the Block isn't contacting the cpu 100% some said washers would help tighten things up so i went ahead and got my self some washers for the black plate and a arctic silver 5 thermal compound...
here comes what worries me:
1-I have some 70% isopropyl alcohol swabs/swipes are they good to use to clean off the block and cpu? its all i could get right now.
2- How do i install the washers on the blackplate? is it washers>plate>screws or is it plate>washers>screws?
3- best way to apply thermal compound? middle of the cpu and how much?
4- i need to clean the cpu with a lint free cloth? now is the cloths that come with glasses lint free? can i use these?

Also regarding static its my most worry right now i don't have a anti static wristband so whats the best solution..i know i shouldn't be working on carpet but my Pc will be on a table and ill be wearing some shoes..? does this help or should i just move to another room? is there alternatives to the anti static wristband?

as i said its my first time doing anything like this i had this computer built for me, so i only know the basics from watching a lot of tutorials

thank you for your help and time :D

Good news! My 13 year old middle school students do this safely (unless they drop something).

Re-pasting a cooler is comparatively easy. I use isopropanol and decent paper towels and have never had any residue.

Before solving a problem it is important to know that it IS the problem.

What cooler, and what motherboard?

We live in a humid climate and work on a tile or vinyl tile floor with no wrist-band. No problems so far.

When you take the old cooler off look at the contact between the cooler and the CPU to see how much paste there is. It should not have oozed out from under the block at all. If you have questions take some pictures and post them and we can help you better.

You will need to remove the CPU from the socket to...

A blob the size of a small pea in the center of the CPU is the 'usual' amount.

Well done. You can see that the cooler needed more paste and was not working efficiently.

I get my students to put the paste on and re-install the cooler. and let it sit for a day. Then we take the cooler off again and look at the contact. That way they learn the right amount.
