<p>You can experiment with this setting if you want- sometimes 99% works fine and slightly improves performance. Or you can leave it alone-- these heat shutdowns are not really very good for a computer.</p>

<p>Abracadabra; adjusting 'Maximum Processor State' (in 'Processor Power Management') -<br/>so it does not exceed 95% of its capabilities seems to be doing the trick - as Roy pointed out. Thanks!</p>
<p>Will try new thermal compound anyway - maybe i can switch back fan spin after this .</p>

<p>Doesn't that mean that turning your CPU 95% down it will run only at 5% of its full horsepower? Does it mean that the rendering will then run 20X longer than of full CPU throttle? Or did you mean to set the CPU usage to 95%? Are those 5% enough to keep things cool enough? Interesting issue anyway.</p>

<p>Don't be so sure about power supply. My son's game rig started shutdowns suddenly. We changed even the mo-bo without any success. Shutdowns continued. Until I did p.s. swap (from my machine to his). Guess what happened? :) <span xml:lang="de" lang="de">Grüße von Griechenland Thorsten</span> :)</p>

<p>Will try the procedure you have suggested.</p>
<p>Power supply can't be- did not changed anything here.</p>
<p>Thanks George!</p>

<p>It is wise to check the way CPU cooler sits on CPU. You have to unmount the cooler's radiator with fan from CPU and check the condition of thermal compound between the heatsink and the CPU's metal cover. First clean off any of the old thermal compound from both CPU and heatsink. Get new compound of good quality (with silver oxide, not ceramic), apply logical amount of it on CPU metal cover a place back the heatsink, fastening it with its mechanism (different for Intel and AMD CPUs).

<p>It is wise to check the way CPU cooler sits on CPU. You have to unmount the cooler's radiator with fan from CPU and check the condition of thermal compound between the heatsink and the CPU's metal cover. First clean off any of the old thermal compound from both CPU and heatsink. Get new compound of good quality (with silver oxide, not ceramic), apply logical amount of it on CPU metal cover a place back the heatsink, fastening it with its mechanism (different for Intel and AMD CPUs). Connect back the fan to CPU's fan connector on motherboard. Check then temperatures at idle state and under load. AMDs are generally hotter than Intel. It is quite normal for my AMD Phenom to get to 60-63°C under heavy computation loads, even with good CPU cooler I have (not water cooling though). 55° shouldn't be a problem for any CPU I think.<br/><br/>My second thought goes on power supply unit. Did you change (I mean add) any of your computer's parts lately? For instance, did you install some new, super power-hungry, graphics adapter like AMD or Nvidia? It is quite possible that the power supply's wattage limit is reached now during CPU load with the other new big power consumptions as well, so the security circuit of it switches off to protect itself and the whole machine. Check the watts of power supply and get one stronger if required (750W-1000W).</p> Update:

<p>Update:</p>
<p>Measured CPU temperature with cpuid-hwmonitor while rendering a simple scene</p>
<p>On an old machine: temperature stays around 25 C°, even while rendering</p>
<p>On the 'problem pc': temperature rises from 35 C° up to 55C°</p>
<p>- so this seems to be the cause?</p>

<p>Sad to say and thank you all, but none of the efforts been made to figure out what reason causes the shutdowns succeeded.</p>
<p>Seems to be that i can't use this computer with next any longer :(</p>
