At what stage would you say the cpu hits its "likely" maximum temperature?
Mines been sitting at 63c for 25 mins and not budged.

Will this get any higher or do they generally reach a level and stay there?
 
Depends on the ambient temp I think.

Mine when running an 8 hour Orthos test last Sunday started at about 56, but then climbed to about 61 during the day as the room got warmer, and my other PC components/case temps got hotter too.

It's flat out within a few seconds though, so in theory, if all the other temps stayed the same, and you got no heatsoak through the mobo etc, then it should stay the same temp.
 
I generally reckon the peak in 24hrs orthos if possible; but as stated, depends very heavily on ambient temps.
 
Room is at a pretty constant temp and have really good airflow in the case.Its now dropped to 61c so we shall see what TAT reports in the morning.
 
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 :)
 
Thats as it was just finishing Orthos run the sensor sometimes seems to be a little slow after 8 hours of abuse :D
