Does a new CPU cooler take a while to settle?

As the title says, I installed an arctic cooling freezer 13 instead of my stock (noise) cooler on my FX 8350 recently. It was a new build but for the first few days the temp would go to around 50c quite often, and under prime95 load it was hitting 70c before I had to stop it. I had the AMD boost turned on (4.2Ghz)...
Thing is, after a few days the temps dropped to around 30c on normal load and 44c on prime. during this time I turned off the boost and OC'd to 4.4Ghz.
Question I'm asking is, does a new cooler take a while to settle on the CPU, with the thermal paste? maybe it wasn't sitting right?
Or was the AMD boost adding extra voltage causing the high temps?

(When I overclocked to 4.4Ghz I didn't touch the CPU voltage)

P.S.
Getting the stock cooler off was a nightmare, AMD put way too much paste on it and the CPU came away from the motherboard while it was still locked in! I ended up putting the heatsink on the hob and heating carefully/slowly to prise it off..

Nice one, I'll check it out again there. It might have been a combination of the two.. I know from undervolting my phone (SIII) that manufacturers love giving you plenty of voltage just to cover any chips that might not be quite so good.
But from what I heard AMD CPU's are not supposed to go over 70c so the boost function shouldn't really be hitting those temps, although if I remember correctly AMD left the Max-temp blank on their spec sheet...
