AMD Phenom 2 X4 965 Heating issues

thanks for all the good advice and suggestinos i will buy a Arctic-Cooling Freezer 7 Pro Rev.2

Hope not, that is the Intel model. You need the Freezer 64 Pro.

No you are mistaken Stormy, The Arctic-Cooling Freezer 7 Pro Rev.2 is suited for the following:

Socket 775, 939, AM2, AM2+, 1366, 1156, AM3
up to 130 Watt TDP

I am 100% sure, cause it's sitting happily on my Phenom.

On a side note:

Ever notice the ridiculously thick layer of thermal paste on the stock coolers?

I always take it off, and apply one tiny drop of paste that I spread very finely with an old creditcard.

You should almost be able the see through the layer.

A slightly different POV for you...

That "thermal paste" is actually a phase change compound that softens and reflows with heat. It takes a while to settle in perfectly but it does shift it's way around and keep things cool. One of the more common production compounds of this variety is called "Thermstrate TC" and while it does take a few days of slightly higher temperatures it usually settles in within a degree or so of Arctic Silver.

I've been using Thermstrate in service work for quite some time and I find it perfectly adequate. The real nice part of this stuff is that each time the CPU gets over about 60c the compound liquifies and reflows, essentially renewing itself.

The hyper thin layer tactic many use is excellent if the heatsink and top plate mate perfectly... However, most consumer heatsinks are cut from extrusions or hot cast and the bottoms of them are antying but flat. It does take some thickness of application to ensure there are no air gaps between them. The excess is not usually a problem as it just ends up piled around the edge of the CPU top plate where it actually helps take some extra heat off the sides of the plate.

I've been at this for quite some time and as a rule I recommend phase change materials over pastes but if you are going to use paste, be sure to use more than the "ideal" recommended so that you get some gap filling ability out of it.

You're right, they changed/added the bits so that one will go on AMD motherboards. If it was me i would still get the Freezer 64 Pro, if for no other reason than the mounting clip is for AMD boards only and unlike the Freezer 7 can be moved depending on which way the heatsink bracket is orientated (and the Freezer 64 is cheaper than the Freezer 7, anywhere from a couple of $$ to $12 on Newegg).

i was looking round and found that some peoples stock heatsinks keep there CPU at 55C full load and my mate has the AM2 940 quad black edition on stock heatsink and runs at 56C full load just strange how some stay cool

is it worth turning off AMD cool'n Quite in bios to keep it cooler?

That is the whole purpose of Cool and Quiet, to make the CPU run at a lower speed and voltage, saving power and running cooler.

Actually it would run a lot cooler with C&Q turned on...

I'm on a different AMD chip but with C&Q turned on my chip idles at about 900mhz ... yes that's right, under a gig... but rapidly gets up to it's full 2.5 ghz when placed under demand. It ramps up and down in about 10 steps between these two speeds. This makes at least a 10 degree temperature difference when the CPU is idling.

well it is obvius that cool'n quite does wat it says but as it normally only kicks in when working hard it would keep cooler if it was off so fan spins all the time

I have a Arctic Cooling Pro Rev. 2 cooler I just purchased for my AMD Phenom II x4 940 processor and the heatsink does not cover the entire cpu. Is this normal? After I installed it the cpu temperature got up to 67 C in the bios hardware monitor before I finally turned the computer off and reinstalled the stock heatsink.

Thanks.
