Hello, so back in May I built my £1000 gaming rig using an intel i5 3570k CPU. At the moment I'm using the stock cooler that came with it but when I bought the parts I bought a 212 evo aftermarket cooler, which I did not use because it wouldn't fit. It turned out I was installing it wrong and I know I can attach it again so I want to replace the stock cooler. I won't be overclocking but I just want to have a cooler CPU whilst gaming and stuff.

First of all, if it's not worth it please tell me. I want to know all the steps in replacing my CPU stock cooler. I know how to install the 212 evo, but I want to know how to clean the CPU and how to apply the thermal paste ect.

What is the best way to clean the CPU? I ham considering buying a pack of 100 (lowest amount I can find) isopropyl 70% alcohol swabs, is that enough alcohol?

And what is the best way to apply thermal paste, and what should I use?

If you can answer these and provide steps to replacing my CPU (not instructions on installing the evo, I know how) I would be very grateful, thanks :)

Yes. Lay your case down sideways, put the heatsink over the CPU, then screw each of the 4 screws into the mount a little at a time (you get more even pressure than if you screwed in one corner fully before starting on the others).

Here's the PDF manual if you've lost the original - if you've only got one computer (and cannot see online instructions when you're doing it, it might be worth printing it out first):-...

You don't need that much iso, a little bit on a clean rag is more than enough. As for putting thermal paste, there is a million different ways and a million people saying their way is the best.

Myself, and this comes from doing thermal paste on probably 1500 PS3's and XBox 360's is to put a bit and I spread it out smooth with a piece of an old credit card. After 1500 though, I know how much to use and what looks like a good layer.

Okay, if I don't have an old credit card what is the next best thing to use? I heard sprading it around though causes it to trickle down the sides of the CPU?

Also, should I go for some swabs of isopropyl or a bottle and a rag?
Thanks,

Ah okay.

Also, when I install the cooler should I lay my PC on its side? I think I should when I apply the thermal paste and install the heatsink because it could weigh down the mobo and I could risk breaking it. So, after I install the bracket on the back of my case (there's a cut out) do I need to lay my PC down?

Thanks.

It might also be worth doing a "dry run" first - just put the dry heatsink onto the CPU (after you've cleaned off the old compound on the CPU, but before you apply the new thermal compound) and line up and screw them into the backplate halfway (just to make sure everything lines up), if it fits, then unscrew it, apply the thermal compound and rescrew them.

If it doesn't fit, if you look on the retention bracket (the thing with the screws that you put over the heatsink case and screw down), you'll see at each corner the screws can have 1 of 3 different positions (inner, middle & outer) - make sure all are at the middle position for socket 1155 (which is what you've got). Do this by lifting each out of line screw up, then moving the screw to the middle position, then releasing it.

Hope this helps!

Okay, I hjave a laptop to watch videos on how to install so it's ok. I might do that "dry run" too.

I found this thing on Amazon called Arctic Cooling paste remover + garnish or whatever, it looks really good and I might get it: http://www.amazon.co.uk/gp/product/B000BKP306/ref=ox_sc_act_title_2?ie=UTF8&psc=1&smid=A1D873RMPMIV2C

Is it worth it? Also, I'll buy some thermal paste with it (MX-4)

And lastly, is there anything I can buy that I put the alcohol/liquid stuff onto to clean it? Or can I use anything?

Thanks

I haven't tried the AC paste remover so I can't comment, personally I find ordinary isopropyl alcohol works just fine. MX-4 is a great choice. As for fancy cloths, etc, you don't really need that. I find 2-3 sheets of paper towel / kitchen roll does the trick. Just use one "dry" to wipe as much excess off, then spray a bit onto the paper towel and gently wipe it off the surface and repeat until it looks clean.

I heard paper towels are bad to use because bits of it gets wet and comes off onto the CPU. Will a lens cleaner work as a cloth for the CPU?

Probably. I only lightly spray about 1-2cm2 of the towel - I don't soak it all in alcohol to the point where it starts breaking up. (And I meant the "strong" type you use in the kitchen, not very soft tissues).

Oh okay,well I ordered the CPU Arctic cleaning kit along with some Arctic MX-4 TIM. Are you sure a glasses wiper will do the trick? It's one of those blue ones. Should I rinse it after I cleaned the CPU and then use it again for applying the garnish, or what?
