No solder does not melt at 77c to 85c.That won't even make water boil.For example lead has a melting point of 621 OF (327 OC) and tin melts at 450 OF (232 OC). Alloying 63% tin with 37% lead forms a eutectic that melts at 361 OF (183 OC). Note that this particular alloy's melting point is lower than either of the parent metals.http://engr.nmsu.edu/~etti/fall97/el...cs/solder.htmlQuote:

Well..if you dont trust CoreTemp, why not just use Intels own. I doubt they dont have a clue about how to monitor THEIR own thermal diode :rolleyes:
And remember there is a huge difference between measuring the internals and outside of something with heat exsposure inside or outside. :fact:
Coretemp guesses a tiny bit it seems, due to it seems to try calculate temp a tiny bit in advance. But the difference at full and idle load is never more than 1-3C.

LOL, oh dear, not all solders are made of lead and tin, its an LMP with Indium creates a much lower point for the liquidus phase (ooooh scary I even can even remember how to read phase diagrams and it may not be a binary alloy so check the ternary PTD) and people have removed IHS at that temperature 77C. Its totally liquid by 85C, plenty of these solders alloys melt in the 70 range, so be careful.Quote:

Here's a pretty mad thread, I haven't seen one work after the surgery yet.

BTW,water can boil at the temperature, I'll let you figure that one out.
Coretemp guesses in advance? Clairvoyant programs, I like that.Quote:

TAT is old, it's not even designed for C2D's, its designed for mobile cpus with a much higher TcaseMax.

I guess i will just replace one more fan with a panaflo and the temps might go to 57C for both cores lol
The TcaseMax for a E6600 is 60.1C. However TcaseMax is the outside temp if you check the spec PDFs.Quote:

And TAT is old? Its from april 27th 2006. And its designed for all CPUs that includes a digital thermal monitor. incl P4/P4D.
Also I doubt Intel suddenly developed a whole new thermal sensor just to do the same thing.
Well my BIOS reports temperatures about 15C lower than Core Temp, so I would agree that something reports temps 15C lower than normal, but not Core Temp heh.
About Tcasemax, i think that the relative temperature reported by the integrated digital thermal sensor is not referenced to Tcasemax (that is an external temperature) but to Tjunctionmax, that is an internal temperature, much higher that Tcasemax; this is logical because the DTS gives an internal temperature. The Intel datasheet too gives recommendation on the method on how to measure Tcase, which means that the DTS temperature is for sure not Tcase.Quote:

As you have, I've read the specs, "The Coolest" says Coretemp is derived from the TcaseMax MSR. Fair enough can't argue with that. But if it is, again "The Coolest" says that's the way Intel specifies it, I still don't see the relevance of junction temperature referenced against the maximum case temp TCM. So I agree and I've said it before, why isn't it referenced against the maximum junction temperature, which is of course higher. If you can find any documents with a hint of Tjunctionmax I'd like to see it.Quote:

Here's the thing, who gives a toss what the junction temperature is? Avoiding throttling is about all they're good for. All the HSF thermal dissipation calculations, system builders and not to mention me. Go on how much heat energy and casing temperature to deal with. If I need to spec a radiator and flow rate for an engine, do I care what the combustion temperature in the chamber gets to? no. I need the heat load and cylinder head jacket temp. So I'll stick to the Tc, like I have for the last 10 years. What would be useful to know is the delta offset from case to junction and then I can use core temps.
So I replaced my stock Intel cooler today with a Ultra-120 and a low speed panaflow fan, and the temps dropped only 5c under load with Coretemp, which means 70c instead of 75c...isn't that sweet?
For sure the DTS temperature is not referenced to Tcasemax. Let's explain the reason in detail. The DTS gives the delta between a reference temperature (let's name it T_star) and the current temperature of the core where DTS is integrated (let's name it T). So the output of the DTS is:
Delta_T=T_star -T
Coretemp takes Delta_T and read the temperature as:
T_Coretemp=TCasemax_tilde-Delta_T
where TCasemax_tilde is in fact not TCasemax but another reference temperature that Coretemp takes from a MSR of the CPU. Anyway from TCasemax_tilde (85 C) and T_Coretemp we can find Delta_T, that is the output of the DTS. Now in my case in idle state at 3.4 Ghz 1.4 V Coretemp gives 52 C. So Delta_T=33 C. If the DTS output would have been referenced to TCasemax of my processor, Tcase would have been 60.1 - 33 = 27.1 C, that is impossible because now at Naples where i live we have 30 C ambient temp....
So we can conclude that the DTS output is referenced to a temperature higher than Tcasemax, that is the maximum tempetaure that the core where the DTS is integrated can reach. Now it is not important the absolute value of this temperature, but how far from this value we are...so the only important measurement here is in fact Delta_T, and this value should be exposed by Coretemp.
