Right from my initial use of T2 I experienced some crashes during renderings that were taking over several hours to complete. Oshyan advised that this was probably due to CPU overheat. Not I, not my machine, I said, I monitor that! Oh well. Osyan thank you, you were spot on. I installed a free utility called 'realtemp' and low and behold at 100% load (i7 920 4 core) the temp rose to 97c. So I just purchased a Corsair H100 liquid cooling system that claims to keep the CPU temp at 66c at 100% load. Having gone thru the support conversations here on the forum regarding freezes and lock-ups, heat was often indicated as the culprit. So first chance I'll install the cooler. I did test a similar situation with a Vue render and the temp range soared to an unstable range as well. It does appear that Vue was not as 'sensitive to the heat build-up, so no freezes. Even with this possible 'cure' in hand, I still wish T2 had a pause render/save and resume render from save feature. Not a complaint, just wishing.
