Hi
It is hard for me to compare the CPU temp in Win7 and MacOS X. The reason for this is that the tools that I have use shows a lot of information for the CPU and for me is hard to find the same "variable" that the tools are showing. You can check the two images I have just captured after a 10 min idle in Win 7 and the rebooting to Mac OS X. Let me describe my config so you have an idea of the setup.
I use Corsair H105 as a CPU cooler. It is a very good closed water cooler kit but there is one "issue with it". The size of the radiator. It is very tick. Because of this I am with Fractal Design XL R2 case and even in it, H105 fits "very hard" (I have only 1 mm clearance between the MB and the fans).
The ambient temperature is about 22 - 23 C. Inside the case there are: 2 front fans (14 + 12 cm), one bottom fan (14 cm), one side fan (12 cm), one back fan (14 cm) and the two top fans from the H105 (2 x 12 cm). In addition to this I put one extra fan on top of my Corsair RM 1000 PSU (very bad choice for PSU but I found it after I bought it... in addition to the bad technical specs of the PSU the biggest issue is that the PSU fan does not spin until it gets too hot. Because of this I put one extra fan - 12 cm. on top of the PSU fan to create some air flow).
I am not a fan of the water cooling (the idea to have water close to may precious hardware scares me). But the CPU is 140W TDP. So I "migrated" from the classical CPU cooling to this "new area for me". Personally I do not recommend you to overlock the CPU without water cooling CPU block. If the CPU is not heavy loaded then it is fine to use "regular" cooler but in this case what is the point of overclocking? If the CPU is heavy loaded then with 1.3 V on the CPU vCore this 140W CPU will become something like 180-190W monster. On top of this higher voltage means more pressure for the VRM on the MB. In my case the water cooling block "removes" the air flow near the VRM and I have to use some addition active cooling for the VRM (in your case the regular cooler creates some air flow near the MB CPU VRMs).
In 99% of the cases when people overclock the CPU they fix the vCore to some value - this gives a better CPU stability (because the CPU is constantly supplied with all the power it may need). I do not like the idea that when the CPU is idle to be under constant voltage pressure (maybe I am wrong and there is no problem with that). If one day I clock my CPU to some thing around 4 Ghz I definitely will use "vCore Offset approach" - it is more risky to be configured but once it is done I will have "low voltage for the CPU when not under load".
I am sure that IF (personal I have some doubts about 5820k support - Intel 14 nm CPUs are coming this year) Apple supports the x99 and 5820k CPU into the MacOS X then we may see "low CPU voltage on the CPU when not loaded" (but only if you do not fix the vCore to some value from BIOS). I am not 100% sure that even now the vCore voltage is constantly up. The reading from the HW Monitor are pretty much messed up in terms of voltages.
I am trying to find a way to apply all Win 7 hot fixes at once but currently I can not find a way to do so. Is there such option of I will have to with for the auto update to do its work?
