do you guys know how the heatpipes work?
is there some kind of gas or water or something in it?
and what exactly does this gas/liquid do?
A typical heat pipe consists of a sealed pipe or tube made of a material with high thermal conductivity such as copper or aluminium. A vacuum pump is used to exclude all fluids (both gases and liquids) from the empty heat pipe, and then the pipe is filled with a fraction of a percent by volume of working fluid, (or coolant), chosen to match the operating temperature. Some example fluids are water, ethanol, acetone, sodium, or mercury. Due to the partial vacuum that is near or below the vapor pressure of the fluid, some of the fluid will be in the liquid phase and some will be in the gas phase.

yeah thats what i was gonna ask...
some heatsink are huge but they are good coolers, the problem is some mobo can't fit it...

Well every website has different methods of reviewing CPU cooler so a comprehensive list is difficult to find. Don't trust Anandtech and look on forums for user reviews.
Curently these are pretty much the best air coolers:
Thermalright Ultra 120 Extreme for best performance.
XIGMATEK HDT-S1283 for best bang for buck.

i agree with Thermalright Ultra 120 Extreme, but is that with a fan or not?

Why is what?
I mean both of them used with fans. You are kidding your self if you think you can get good cooling performance with out fans. Hell even water cooling needs fans on the radiator.

Remember they had the Freezer 7 Pro posting better temps than a TRUE. They both had fans BTW, so in my mind they are just unreliable from then on.

Thermalright Ultra-120A (not extreme)
3.15Ghz CPU (75% overclock) at 1.41V
All case fans lower than 750rpm
An hour of Supreme commander:Forged alliance
CPU temp? 39C

No I'm not!
I'm going to passively cool my graphics card next. I'm thinking of waiting for the new generation cards before I do that, since if I can get the same level of performance with a single card as I do with crossfire now, and in every game, then spending all that on getting a pair of GPU heatsinks is madness.

Uhuh, now try doing that WITH NO FANS on an overclocked Q6600.
You still have case fans.

Yeah, well I am, Unless you live in England or something where it's always cold lol.
Seriously, I know how horrible it is trying to keep a Q6600 cool. With a freezer 7 Pro at FULL SPEED it still would go OVER 70C easily in about two minutes of running Prime 95 at 3.6 Ghz.

With a freezer 7 Pro at full speed my CPU ran at nearly 50 degrees. I think you underestimate just how much more powerful the Ultra120s are. Not only that, I'm not going to push the Q6600 to its overclocking limit, nowhere near it. This is for several reasons really. Firstly so it doesn't dump so much heat into the case I have to turn my case fans up, secondly so it doesn't get so hot I need to worry about having a fan on my CPU cooler, and thirdly so my power consumption remains relatively low. Electricity's not cheap these days. My plan is to run it at pretty much the stock vcore, I'm aiming for a CPU speed around 3.1Ghz or so, in continuity with the speed I have now, but just more cores of it.
Additionally, Prime95 isn't your average program. I've no doubt that my CPU will get hot running it for extended lengths of time, but if it can run that without throttling, then temps running a normal application will be fine. I assume Prime is multi-threaded?

Yeah I guess it will do fine then. Yes Prime95 uses all four cores. Next time I get a Q6600 I am getting a much better CPU cooler and KEEPING it at 3.6Ghz.
EDIT: Sam, also if you want to save electricity why do you keep your voltage on auto?

Because as nice as saving electricity is, I'm willing to sacrifice a small amount to guarantee my CPU's stability - as you know I like overclocks to be plain and simple, and even if it costs me a few watts, that's fair enough. Changing the brightness on my monitor by one notch is enough to outweigh the gains by optimising my CPU voltage.

don't you save elec if the VCore is on auto? why is that so?
my E2160 @2.2Ghz temp is very low, 17 degrees at idle and about 40 degrees on load.
Why some CPU is hotter than others?

If the voltage is set to auto the motherboars selects a voltage that it knows should be stable for the CPU. Most of the time you can run the CPU a fair amount lower than this if you're willing to spend the time finding out how low you can go before stability problems occur.
Your CPU will run cool because it isn't overclocked very far, remember we effectively have the same CPU, just yours has less cache, and mine's running 950mhz higher than yours. However, to have an idle temp of 17C your room must be very cold, a lot colder than most.

@sam
It doesn't take very long to figure out the lowest voltage stable for a certain overclock, and then if you leave it running like that till your next upgrade(6-7 months) w/o any tweaks, it would be worth keeping the cpu at a lower temperature.
For example, if I "auto" the voltage on my e6300, the mobo selects 1.45 volts whereas if I select it myself, I can go down to 1.15 which is awesome cause I can't afford to run the A/C in my house ON 24/7 and if the A/C is not on, the cpu is not stable with 1.45volts running through it. Now, when I drop the volts to 1.15, it is completely stable 24/7 with orthos, prime95, etc w/o needing the A/C.

Fair enough - I might give that a try, certainly will with my quad core when I get it.
6-7 months per upgrade? Wow, money runs well in your household! I've had my E4300 for 16 months, and it'll be another couple of months at least before I get a Quad.

from anand tech
i see wat you are saying here....
but now look (from the same article)
THIS IS WHY YOU BUY CPU COOLERS:
boozer, you cant use just oen screenie.
the last two are the money shot. they are the ones too look at.

lol, i was guessing other ppl who actually have a job probably upgrade their computers every 6-7 months
I am 15 and don't have a job so I tend to upgrade(more ram, new gpu, new cpu) my computer every 10-11 months and if i find a great deal, even earlier.
My experience with upgrading CPUs is that every time you upgrade the CPU, you need a new mobo at least and thats where my dads credit card comes in, hehe.
