Cool down too fast after bake | cracking and popping heard during cooldown.

Hey All,
TLDR; With a panel with low thermal mass, how long should I let it cool before taking it out of the oven?
I've been impatient and usually after 4 min, when PCB is about 120c, I grab them to cool on a silicone pad while I bake the next panel. Would switching to a Pb solder help since the temps would be much lower? As it sits on the pad, I hear cracking and popping as the solder cools.
Is this bad?
Controleo 3 B&D toaster oven
Chipquick SAC305 with peak at 225c
I'll keep searching the forum, but I though I'd burn this candle at both ends.
Thanks for any help.
