Help needed with core temps

Hi all, have just built a new pc (Asus P5Q Intel P45 775 - Dual core E5200 2.50ghz) and when I run Real Temp, core 0 = 52o and core 1 = 31o, why is core 0 so high? Is it an inaccurate reading as when I test the sensors with the same program Core 0 has movement of 0 and core 1 has movement of 5?

I have not overclocked anything so everything is standard, I also have the Akasa AK-965 CPU Cooler. Should I try and replace the heatsink with less paste, although I'm sure I used a pretty minimilistic amount first time!

Also, the frequency part using Core Temp flicks between 1200.04 & 2500.09 (200.01x6.0 & 200.01x12.5), what does that mean? :confused:

Anyone have any thoughts before I start opening the case up again? Should core 1 actually be a lower temp or does that seem reasonble? Thanks in advance and sorry if they are stupid questions! :o :)
 
The bit where the frequency flicks is the intel speedstep which lowers the CPU speed when its not being stressed to save power etc. This can be turned off in the BIOS.
 
Have you got your latest bios installed? its possible if not your computer is not recognising the chip properly, altough I'd of thought it would have as ts not a particuarly new chip.
The frequency is changing due to a thing called speedstep, its a power saving function that declocks your CPU when it doesnt need to be running at full capacity, you can disable it if you want by disabling any options in bios called speedstep, C1E or EIST, this is quite useful whilst youre overclocking and want to make sure your speeds are correct, but i advise you leave it on for 24/7 use due to the power saavigns and some reports say it adds longevity to your chips life.
Both cores should be the same, or at least within a degree or two, if your bios is up to date its possibly just a faulty sensor though, you could try running coretemp as well, see if that gives the same results
 
I see, that speedstep is ok, no panic then :D Will leave it as it is! :)

Core temp program is showing the same temp just 5o lower for each core, I'm a bit worried if I start to OC (which I am planning to do shortly) that I am going to damage the chip if the temps are actally correct? How can I find out if it is actually a faulty sensor?

Will check to make sure I have the latest bios installed, but could that really just not read one core correctly?

Appreciate your replies, thanks :)
 
I see, I will check to make sure bios is up to date tomorrow then (how do I check just to make sure?) and I think I will re-install the cpu cooler just in case. I will try lapping it if it still isn't resolved, going to really annoy me if the chip has a faulty sensor though :(
 
Ok well I refitted the cpu, heatsink and applied a new layer of thermal paste, nothing changed, so I flashed the bios and that is now up-to-date. The sensor for core 0 still seems to be stuck on 52o and doesn't move at all (even ran a game and no change happened so I know something is up and it isn't portraying the correct temp).

Should I just forget about it? Seems pretty annoying that I have a stuck sensor and if something happens to core 0's temp I'm not going to know about it :(

Any more help or advice appreciated!
 
I have stuck sensors on my E8600, sent an enquiry to Intel and they mentioned that the cpu will protect it's-self in an avent.
