The issue I'm having is that lately the computer I built about 2 years ago has started to "Freeze" up during gameplay. The games as of late that I've played have been Fallout 3 and World of Warcraft.
I've never had issues with these games in the past but then all of the sudden my games are locking up and then freezing and the system doesn't shutdown it just locks (and would stay that way until a manual power off via the Power button). It also ends up repeating the last sound it played the very second it freezes.
Windows 7 doesn't reboot on its own and I didn't find anything related to the issue in the event log.
I had that issue with my GTX 460s. Mid game, my screen would turn black and the monitor would display the "No video input signal" message, but the PC was still running. It's most likely an overheating issue with the GPU.
I'm a bit confused by the speedfan screenshot. Most likely, the CPU 0-3 readings are in fact the real CPU readings and not the "CPU" labeled one, I think thats coming from the Graphics Card?
Also, 90c for "system" raises a red flag to me. What is that component? Your GPU not idle isn't that high, some graphics cards are specced to handle up to 90c. I'm more concerned about the CPU and 90c reading.
What is that "system" reading? It should say somewhere in speedfan.
Edit: I'm curious to know what type of heatsink your using? And the big question, are you overclocking? If so, what are your temps nonoverclocked?
I'm not really sure what the "System" reading is. I think it's an "unused" sensor that that is just regulating volts rather than heat since nothing else in my computer touches 90-100C
Ahh good to know. If one of the 120 mm rear fans is next to the CPU fan, and its still in your case, get rid of that rear fan. I think theres some countercurrency going on. I remember trying a similar design figuring it might decrease idle temps, but instead raised them. Switched to this and couldn't be happier:
Its minimal, but gets the job done well. Comes prepasted with thermal paste also. My idles are at 32c on an e7500. It says its up to core 2 duo, but you can get away with using it on a core 2 quad. Otherwise, there should be something similar out there for the quads.
Theres one major con if you decide to use this CPU fan thats actually a big pro for me. Its NOT a pushpin install, you'll have to take out the motherboard, put a bracket underneath then screw it in. And not easily swappable either since you'll have to do the same thing if you change your CPU or CPU fan in future. But its a pro for me because push pins are the most troublesome for me personally and you'll get guaranteed contact with the CPU.
If you decide not to do the switch, take out the rear fan near the CPU and see what happens. Or better yet, switch back to the stock fan and see what happens since your not overclocking (my rule of thumb is you don't really need anything beyond the stock fan if your not overclocking). Your GPU temps don't seem to be too high since its on high load, but one thing that helps on these nvidia cards is manually increasing the GPU fan to 100% during gaming (using nvidia control panel, you may have to install nvidia ntune to get these settings). I've noticed the automatic fan isn't always spinning at 100% during intense gaming.
^cp, You should be right on the 0-3 being correct temps, they're very close to the original temps posted by Op on realtemp and show the same 'pattern'.
any chance of swapping out the gfx card and seeing what temps another card reads?
280s run really hot. They are hotter than the newer 285s. Only thing hotter is a 295.
Speedfan reports alot of invalid temperatures. That 90 degree temp is probably soemthing that doesnt exist on that PC. I have the same problem with it. I would toss it and download overdrive from evga.com for the GPU and coretemp for the CPU and use those.
