....
With the BOXed heatsink and fan I had temp. with Intel Desktop Utilities 22 °C (Processor Thermal Margin).
Is here somebody who know the usage of the Intel Desktop Utilities?
Because what does this mean= 22°C (Processor Thermal Margin)?
22°C to go to the max. temp.? So 65 °C - 22 °C = 43 °C?
OnBoard FanControl: 2.000 RPM.
CoreTemp: 71- 79 °C
[room= 22 °C]

Hi, I thought this might help with those struggling with thermal margin (I was). This guide was for core 2 duo's but the figures for the quads should be easily looked up from intel once you understand them.
http://forumz.tomshardware.com/hardware/Core-Duo-Temperature-Guide-ftopict221745.html It was a link I found on seti forums (I think),a short while ago. I think it is in simple language and should make anyone a wizard on "Thermal Margin etc...". As I understand it ( perhaps wrongly ) thermal margin is the difference between the core temp and cpucase temp , 15C for a C2d (.... and 22C for a c2Q ?)
So by my understanding in your original situation you say Tjunction(core) = 71 to 79 C, Tcase(heatspeader) = 65C .... so that makes a thermal margin under load of 14C ... which is close to the spec of 15C for a c2d, but if it's a quad then it would probably mean the offset needs tweaking (in Speedfan) I guess to correct for innaccurate mobo/bios/chipset reading. ( I think the new offset adjusts the tcase reading down - from 65(innacurrtae bios reading) down 8 degrees to 57, which fixes the numbers!!! yay, 57+22 = 79C )
for the quad cores I would imagine higher cpucase(heatspreader), and higher core temperatures would be specified. for a c2d 65C(case) and 71-79 C would be considered "Hot", though I have heard of people driving them much harder than that.
I would love to know what the "intel specified" values for quads are if you find out.
[ Later: Found something...
QX6700 = 130 Watts , Max tcase at fullpower = 64.5C ( at full power, but we are really only 58!)
Heres something "In the event of a catastrophic cooling failure, the processor will
automatically shut down when the silicon has reached a
temperature approximately 20 °C above the maximum TC" So I guess we can TRY and invent a new table for the quad
Loaded
tcase tcores mode
62.5 84.5 thermal shutdown
60 82 Hot
55 77 warm
50 72 normal
45 67 normal
40 62 normal
etc,,,
So If yours is a quad then I think your adjusted tcase of 58C, and core temps of 79, were warm warm, but not quite hot.
and your upgraded cooling giving tcase=50 and tcore=72 sounds much nicer is now reporting spot on 22 degrees so offset won't be needed in speedfan ( if those temps didn't use an offset already )
Can anybody confirm or deny they really run like this ? I mean 82C cores perhaps you could use it to cook eggs somehow.
