Would you return a processor for a faulty core temp sensor?
- Thread starter Merlin5
- Start date
heres mine overclocked
you must have a pretty cool room to have those temps,, if correct.
Guys, I know I look like a computer hypochondriac, but I assure you, the last thing I need is to be sending stuff back, I'm not looking for faults for the sake of it, honest! 
I only brought this up because I posted how nice my temps are on a forum, only to get replies that my core temp must be wrong. Which then made me start to worry, or rather, feel disappointed.
Anyway, I'm currently running intelburn test on maximum stress, which is meant to be more intensive than orthos and prime, and indeed it does slow windows down more than those, and there's no heat whatsoever around my pc, just cold air, and my temps are 41c cpu and 24c core, same as for prime and orthos. So my temps must really be low. I don't know what temp I'd start to feel heat at, maybe 50c? Gareth, that's very interesting and good to find someone else with similar lower core temps than all other temps. Are you saying that your core temp and my core temp are absolutely correct then, give or take a degree or two? I hope so, lol. And that the higher bios temp for cpu is also correct (for whatever reason it's higher than core)?
Tried to buy a digital thermometer today for ambient, and got stuck in traffic so came home empty handed.

i didn't say it would the temp below room temp.
but it helps to keep the temps alittle above room temp.
i might be wrong here guys, and please tell me if I am..... If a pc is turned off and room temp is 20c, that means your cpu will be 20c aswell??
So if gareths room was lets say 18c, the cpu will be 18c when pc is off.. so If his temps are right, that means the temps has only increased by 3c from the pc being turned on from the off postion... It just sounds a tad impossible thats all???

if my room is 16c, and my cpu is 21c at stock , thats 5c over room temp, which could be posable. also if u see the tcase it's at 29c so u need to watch both.

Well, if the temperatures are *always* reading 14-18C less than those you consider to be accurate, then just take that into account and business as usual. I know that speedfan has a temperature offset function if you're using that, otherwise it doesn't really matter does it?
This only applies if the difference is pretty constant, obviously if it's a changing difference then you've got more of a problem.

if his is fault then many others are faulty includeing mine. which i really don't think so.
i've seen a lot with am3 cpus that have low core temps.
I get more confused by the second if there's a fault or not. Some people say there's a fault, some people say there's nothing wrong. How on earth do I know what to believe. no one seems to explain the reason for gareth's and my cpu temps being higher than core. Yet plenty of people have said that core is always higher than cpu. And that is aside from the other argument about low core temps of 20c v ambient.
Temperatures should be lower in windows, than when read from bios. Bios doesnt bother putting the CPU into idle cycles, so the cpu is under partial load while monitoring voltages and temps via the bios.
But boot into windows, and anytime the cpu is idle, it's constantly being put into a low power sleep state (for 1 clock tick). So as soon as the PC's booted up, the temperatures should drop.
As long as the temperatures increase by a believeable amount when you put the cpu under stress (say run prime95 while watching the temperatures) then you have nothing to worry about.
Temps in bios are usefull when building a system, as they can give you a clue as to the temps of your system under "light stress". But the real numbers are temps when idle and under full load running the OS of your choise.
If you just mean the temperature from the diode on the motherboard, I wouldnt trust those sensors at all, and to be honest the temps from other applications such as everest are pretty much a guess too. The only number that is truely meaningfull (if you can read it) is the Tjunct delta temp. This tells you exactly how far away from the "throttle" point you are. a 25degree delta at full load for example is excellent. If your delta's at 5degrees then come a hot sunny day, your gonna overheat.
All the other numbers are "estimates" based on hints given by intel engineers. Trouble is intel keep changing the delta "reference" so in 1 core, the throttle point might be 100 degrees, and another could be 85 degrees. Temp software that doesnt know the exact details of the chip you have will have to guess the delta's reference point to guess the actual temperature.

Stock cooler, 12 c increase from 32 to 44c under orthos., 100% load.
New cooler, 3c to 5c increase from 20 to 23/25 under orthos, prime, intel burntest, 100% load.

Interesting, seems there are a few others with similar 'phenomenon' if it can be called that.
