CoreTemp or Speedfan?

Davidian · 14 Oct 2007 at 12:43

I'm new to this not started overclocking yet so everything still at stock, so why the big difference in core temps between the two?

Speedfan v4.33
Core 0 - 31C
Core 1 - 31C

CoreTemp v0.95
Core 0 - 47C
Core 1 - 46C

Which one is correct? :confused:

Try Intel TAT as well, I find that to be the most accurate. There's a massive difference there so its rather hard to say which one is right.

If the fan is fitted correctly I'd say speedfan, but if the fan is not seated properly then it will be core temp.

TAT, Coretemp and Everest all give the same results for me, Speedfan is the only one that shows a 15C temperature difference. So speedfan just needs adjusting, its designed that way.

Get this when I try to run TAT v2.05?

Try Everest as well

Got Everest Home edition v2.20.405 and I can't see any core temps?

Doesn't recognise my mobo reports the motherboard name as "unknown"

Also confused at the voltages reported in Everest?

Everest
CPU Core - 2.19v
+2.5V - 3.22v
+3.3V - 1.54v
+5V - 5.05v
+12V - 12.22v
VBAT - 3.10v

BIOS voltages
Vcore - 1.31v
3.3V - 3.36v
5V - 4.94v
12V - 12.28v

Is this a mobo compatibility issue?

I only use coretemp and tat more reliable in my opinion pc wizard 2007 also show correct temps as well in relation to coretemp. Regarding voltages i uuse cpuz and the bios. Personally i dont like speed fan, onlu use it when running prime to see all four cores on fire

Is that right? I thought the difference was due to the fact that CoreTemp and TAT read the temps straight off the die, while Speedfan reads it from somewhere off the edge (and hence appears cooler).

Me too, apparently it doesn't work with all mobo's.

That said, Coretemp underreads TAT on my set up by between 5 and 10C - is that normal? Which to believe?

Troop · 14 Oct 2007 at 18:06

Think I would believe TAT.

That being the case and as I can't seem to use TAT, I'll stick to CoreTemp and CPUZ.

Thanks for the info everybody.

Does it ask you to run as an administrator? if so, right click on the icon and... run as administrator.

Davidian · 15 Oct 2007 at 12:48

I'm logged in as 'administrator' when I get the error I posted earlier trying to run TAT.
