542879 2007-04-26 08:15:00 Sims2 running time depends on what mode I am in. Building mode is when it usually crashes and thats what I mostly do (I dont really play the Sim characters at all really) and it can be short or long (10 minutes to 30 minutes)

I am worried that Prime95 might overheat my CPU.
What are the chances of that happening?

542880 2007-04-26 08:29:00 If it overheats, then the system will shutdown before any damage can happen to the CPU, but it is very unlikely that it will over heat (as long as the heat sink and fan is on properly and you are not overclocking (which I would say not)) a CPUs HSF is designed to be able to easily dissipate the heat that it produces at stock speeds, yours will be fine, but get Speedfan (www.almico.com) and install it, run it and it will tell you the CPU temp (usually Temp 1) tell us what this is while only speedfan is open and running, then get Prime95 running and about 30 mins in record the temp and tell us.

542881 2007-04-26 08:54:00 If the system is crashing and its not a memory issues then chances are its a heat problem. Prime95 will put the CPU under intense load, far greater than anything the Sims will subject the CPU too. If its still going strong without crashing after an hour then its fine to turn off Prime95 and move on to testing other components.

The P4's had built in thermal protection that caused them to shutdown if the temperature got too high. Don't be worried about overheating the PC. If the PC shuts down or crashes its a good sign, at least we've then identified the culprit :)

542882 2007-04-26 10:40:00 I have GIGABYTE Utility manager installed and that gives a CPU temp reading. Will that be ok or should I down load Speedfan? meg_h_nz (6960)
542883 2007-04-26 11:09:00 No, that will do fine, anything that can read out the temps, I said speedfan cause it is good and easy to use... but seeing as you have the Gigabyte, one use that :) The_End_Of_Reality (334)
542884 2007-04-26 12:31:00 Temp sitting at 66 degrees C. Is that High? meg_h_nz (6960)
542885 2007-04-26 12:45:00 Temp sitting at 66 degrees C. Is that High?

Is that before, after or during the Prime95 test?

542887 2007-04-26 20:07:00 Temp sitting at 66 degrees C. Is that High?Althought that's tolerable, it is high for your CPU. Mine sits at around 35. Greg (193)
542888 2007-04-26 20:08:00 No, that is fine, P4s do run quite hot and then there is the Prescott which is even hotter :eek:

What is the exact model of P4 that you have?

What type of PC is it? (Desktop, tower etc)

EDIT: how long did you have Prime 95 running for?

EDIT EDIT: just thinking about it, that is rather high... depending on you actual CPU model it could even be close to the max recommended temperature...
