*off topic, how are temps on your Q6600 around 3ghz? I am going tuniq120 for my Q6600...so just wanted to know, where to expect my range. I have heard the Q4's run around 10-15c hotter @ the same clock as a C2D...any truth?
Yes, truth. Lol it's 2 cores giving off heat compared to four.

So in that sense..why are the factory temp specs the same? It seems like you would void your warranty, simply by starting the cpu. I cant fathom how the stock coolers are designed to keep a Q4 below Intel$ recommended temp.<- rant...sorry.

So 50c around 3ghz on air is acceptable for a Q4 then?

Well they are a little different, but not much.

Thermal Specification of the two CPUs.

E6600 : 60.2C http://processorfinder.intel.com/det...px?sSpec=SL9S8
Q6600 : 62.2C http://processorfinder.intel.com/det...px?sSpec=SL9UM

But keep in mind that number is the Termal Specification.
Quote:
Thermal Specification: The thermal specification shown is the maximum case temperature at the maximum Thermal Design Power (TDP) value for that processor. It is measured at the geometric center on the topside of the processor integrated heat spreader. For processors without integrated heat spreaders such as mobile processors, the thermal specification is referred to as the junction temperature (Tj). The maximum junction temperature is defined by an activation of the processor Intel® Thermal Monitor. The Intel Thermal Monitor’s automatic mode is used to indicate that the maximum TJ has been reached.
So in other words, that is the number at the center of the the top of the IHS. The individual cores can be much hotter than that. So even keeping your cores at 62.2 is well within Intels guidlines, by as much as 10C depending on the difference between your temp at the center of the IHS and the cores themselves.

I need to just put on the stock cooler on one of my quads and run it full load. You will see that the stock cooler cant hit the 55C with no overclocking.

One thing I do find very interesting is the QX6800. These are the ones that were sold to select vendors because they should be water cooled.

Qx6800 54.8: http://processorfinder.intel.com/det...px?sSpec=SL9UK

But the TDP, or Thermal Design Power on the Qx6800 is 130W vs the 105W of the Q6600.
Quote:
Thermal Design Power: (Also referred to as Thermal Guideline) The maximum amount of heat which a thermal solution must be able to dissipate from the processor so that the processor will operate under normal operating conditions.
So TDP is the amount of heat your cooling solution should handle.

What this all says to me is the QX6800 requires that you run it at a lower temp, and have a cooling solution that can handle a more heat in order to stay within Intels guidelines (But we are Overclockers, so we dont believe in manufactures guidelines ). Seems to me like the QX6800 is a much poorer choice of a processor than the Q6600 because of these limitations.
