I got an E6600 yesterday and opted to get the Arctic cooling Freezer 7 Pro for it.
The E6600 is a nice one (I think?), it seems happy to overclock to 3.2 at its stock voltage of 1.225v - unfortunately with the AC F7p (this heatsink's name is too long) it reaches ~60C in coretemp running orthos, it gets worse when I try to go to 3.6ghz, it needs 1.4v to do that, it then reaches 70-72C.

I've tried remounting the cooler and using ceramique instead of the pre applied stuff although it hasnt made a lot of difference. One thing that's bothered me is that the IHS has more wear marks on the outer edges of it rather than evenly worn, suggesting that it's not particularly flat.
I know the AC F7p is a better cooler than what I'm getting from it, although its fan is having a lot of trouble moving air through the heatsink at full speed, and the base isnt very impressive.

edit: the other problem I'm having is that when it reaches this temperature, the motherboard (DS3) starts making the scroll lock light flash and the pc speaker beep a lot at this speed/temperature/voltage

The standard stuff is usuall very good, have you made sure its runnung at 100% rpm, facing the corect direction, and if the 4 clamps of the cpu are on correctly?
Your c2d sohuldnt be that high tbh, i have a p4 with a 1.1ghz oc and a higher vcore and its still below 50 when stressed while mine is a lot hotter... (the cpu)....

Whats the fan rpm you are getting?

The fan is plugged into the 4-pin PWM fan connector, it spins up to 2800rpm at full load, and I can definitely hear it at that point :)

Is there a special way to fit the 775 coolers? the manual/what Ive read says I just need to click the pins into place, it certainly seems as though its fitted right
 
its it facing the right way? ie. the back of the heatsink is next to your rear case fan so that the ac freezer7's fan is blowing air through the heatsink and out of the rear case fan like so...(excuse pic its taken on my phone)

I have a DS3 and an ACFP7 but with an e6300 and my temps dont go over 56C when running Orthos. In the bios settings make sure you have:

In the PC Health Status menu, set the FAN Speed Control Method to "Legacy" & FAN Speed Control Mode to "PWM" to maintain highest speed.

how do you know that? is the board defaulting it to that
im sure the stock volts on mine according to the board (bios) is 1.35v
though the cpu z, says it is running slightly less @1.32
 
You have a concave cpu or dodgy cooler (unlikely) - you need to lap it to get better contact (may as well lap artic cooler as well)

Stock voltage on Conroe is 1.3-1.35V.

As all the boards undervolt, at stock voltage the CPU is getting about 1.25-1.3V.


At 1.25V I could get to 2.9ghz, 1.3V I got to 3.1 and 1.4 I got to 3.3. 1.5 netted me 3.525ghz.


AS for the cooler, try and reseat it? As thats worse than my stock cooler.
 
I think the OP is quoting core temperatures which are fine - the socket temps will be 20-30C lower than the core temperature. So he's actually at about 40-50C socket temperature, which is fine.
