its about 5 seconds to 10 seconds to reach full power, but then your into heat soak and system capacity...
ive got about 30L of water in my res - i can run without any rad (or the bong) for an entire day if i back clock down by 80 mhz.
takes about 45 mins or so to heat water about 1c. but water keeps on heating up (its been past 30c) given the time. (eventually evaporation from res and heatloss thru pipes sets a cap on temps)
with rad (passive, house rad) it stops at 27c and holds there after about 4 hours on average (orthos - more for games)
with air cooling/closed loops with much less heat capacity you will max out much faster, id assume heatsink saturated in 1 min, but, heatsink then becomes case,and case will saturate in a few mins, then room temp utill room saturates then its ouside world......
by saturate - i mean the heatsink/rad/case/room temerature rises depending of the energy being put into it. on the other side of that, if falls as energy escapes. the hotter it is, the faster energy escapes, eventually it gets sufficintly hot that the heat lost is equal to heat input. (then temerature moves in line with ambient temps, ambient +10 = sink +10) likewise for case temp, only this is down to airflow - how efficiently the airflow thru case is as removing the energy, hotter = more energy tranfered
this is how i understand it.
so if temps dropped to 61 with nightfall, id assume you already peaked.
it will probably drop a little more with room temp, and more still if its a new install with thermal paste settling in.
good luck on stability
