Did I apply the thermal paste incorrectly?

I recently pulled my first ever build apart to do some cable management and had to replace the thermal paste on the cpu/heatsink when I put it back together, now I have noticed my CPU is running around 2 to 6 degree's hotter then before averaging around 38c/41c rather then the 34c/38c that I was getting before at pretty much 1% load.
Is this due to the Arctic Silver 5 still needing to cure correctly or is it because I didn't apply it properly. Also when using prime95 my temp maxes out at 78c/80c and I am using a H100i CPU Cooler in a CM Storm Enforcer case

I would give it a couple days of running to stabilize. Ideally, a small spot spread very thin with something like a credit card without air bubbles is a good way to go.

Ok I will see how it goes as it's only been about 32 hour's since I had it applied and from what I read AS5 has something like 200 hours to cure. I used the pea method by the way and just put the heatsink on top and after screwing in one corner slid it back and forth a little to spread the paste a little more before securing it completely.

Yes, it does take days to cure, it sounds like you applied it properly.

I don't think that spreading the paste like you did is a good choice. You should've just apply it with the pea method and secure the heatsink.

And in my experience, if you don't see improvements within one or two days (after applying the paste) than you've messed up something

I haven't seen much improvement so far so I have ordered some ArtiClean to follow the procedure to the letter and how if that work's better. I figure if I do it exactly as the guidelines say I can't mess it up + I will have the cleaning solution for a long while afterwards.

Some guidelines advise you to spread the paste, they even give you a kit to do that. It's best if you do the pea method (on the CPU) and carefully place the heatsink, and make sure that it is well secured and tight. Good luck.
