I usualy use Hwmonitor to check what temps I get while I'm playing games. Today after a few hours of gaming I was vrery surprised to find out that my cpu according to HWmonitor reacht 73 degrees Celsius. What I want to ask is if this actually can be true because I find it hard to believe that my cpu reached 73 and still be alive considering that its thermal limit is 71.
What CPU is it? Depending on the CPU, motherboard and settings in the BIOS you may not have noticed it hitting its thermal limit while gaming if the CPU responded only by throttling itself rather than halting the system or forcing a reboot. The actual temperature sensor reporting the value to the program is more likely to be at fault than the program itself. Temperature sensors on consumer-grade CPUs, Motherboards etc. supposedly aren't precisely calibrated and can be out by +/- 15 degrees Celcius.
I have a Q9650(no overclock) and a Gigabyte GA-EP43C-DS3.I've never made any settings in BIOS so I think evreything is on default there. Well this may be a posibility but most times I think HWmonitor reported the true temp because on average on the same games I play my cpu reached between 54 and 58. It is posible whatever that sensor or that program to go wrong just one time?And if not and my cpu realy reached 73 why such a huge jump over the average?
My Asus p5k gives my a reading of 122 Degrees Celsius. Some times there can be dodgey probes. Maybe you're HSF is full of dust?
That's what I hope. I think this is not the case because as I said before this was the only time my cpu got 73 ,usualy it gets between 54-58 .
Well if it does it again start checking for background processes running , anti virus scans can use a lot of resources. it may have just been a dodgy reading. HWMonitor some times tells me my CPU is drawing well over 100,000 watts. I shut it down a restart it and it tells me thats it's actually 38.7 watts.
I did a bit of reading about TCase and TJunction a while ago. Intel TCase is a temperature sensor between the cores which typically typically run around 5ºC hotter. Intel recommends you don't exceed that temperature on a regular/continuous basis for, as I understand, the possibility of degradation is higher. Bear in mind though that the TJunction for the Q9650 is around 100ºC which is when thermal throttling will kick in. As an example the TCase for a Core i7 920 is around 68ºC so core temps would be around 73ºC if that were achieved but many people are 'happy' to run theirs a lot higher relying on thermal throttling to 'kick in' should the threshold at around 100ºC be reached. Personally I try not to exceed 70ºC but I've not found any examples of degradation for those that run higher than that although I haven't looked it up for a while. The Q9650 normally runs pretty cool and mine ran about 40ºC above ambient on air at 4GHz so as others have suggested you may have a mount/TIM problem. I'd also try Real Temp and/or Core Temp. Core Temp has on Overheat Protection option to allow you to shut down or sleep the system if a specified temperature is reached. I use that for my watercooled systems for if the pump fails.
Thanks for your replies,I've just played the game that supposedly caused me this temp , and this time my cpu reacht 57C as usual . The only backround processes running while I 'm gaming are Hwmonitor and BitComet ,so I think no big resorces are drawn. Also I've remembered that core 0 was also 73 like the cpu was wich I asume it is imposible so it might have been just a dodgy reading after all. Altough I will try reseting my poor stock cooler(it also may be very dusty) to see what will happen . Sadly the temperature diferece between the cpu and its cores are grater than 5C in my case(more than 15C in idle)
i have had core temp, hw monitor, speedfan and realtemp running with all different temps showing as far as i can see, its to do with the tjmax. in real temp it was set a 90 tj max and the distance TO it was 65. yet when i set the tjmax to 100, the distance was still 65 the same result with the tjmax at 80 so even at load with prime95, i go by the distance to the tjmax which is 40, so i know i am well under it. i do have coretemp running all the time with all cpu meter (gadget) but i allow +10.c on it to match realtemp (realtemp tjmax is 100)
The Tjunction of the B3 is supposed to be 80ºC but I have seen 85º mentioned with a TCase of 61ºC. You can edit the RealTemp.ini file to display correctly the TjMax by adding/amending the file as follows: TjMax0=80 TjMax1=80 TjMax2=80 TjMax3=80
