Do I need to clean new CPU and new cooler prior to install

[PCSharkey]

I seen linus cleaning the CPU and cooler in a fresh build, I unfortunately cannot find 99% isopropyl alcohol anywhere for a decent price or in a decent time frame, I have 70% alcohol wipes but i'm afraid about the water content or the apparent impurities they leave.
If you could help me out that would be great.
Thanks

You should be fine my friend! He only does that because he's used them before.

you don't have to, but don't forget to use thermal paste.

I had trouble installing my CPU cooler (first build) and I cleaned the CPU with 70% before trying again and re-applying the thermal paste. I also did this to the cooler before trying again, but I wasn't planning to do it the first time, there's a sticker at the bottom anyway.

 

So yeah, I used 70% alcohol and it worked for me, no problems. If it's brand new and you remove the sticker before installing it you'll be fine. If the sticker was already removed a while ago (not just 30 seconds, I'm talking about quite some time) or there is no sticker at all on the new cooler, then I suggest wiping it.
