mm i love it cause it dropped from 50 to 47 45 which isn't that bad in my case with a stock fan for my socket 940. is it okay also to use it when watercooling and how often would i have to change it in order to keep the temperature low?

First of all, in all honesty, you probably seated the heat sink a little better with the AS5. I'm not saying you didn't take care the first time, but can you be sure the thing wasn't seated with processor/HS surfaces .5° from parallel? Or that you didn't have a teeny-tiny bubble in your thermal compound the first time? Or maybe you missed a microlayer-thick dot of finger oil with propanol when you cleaned the HS the first time, and it just burned off or got absorbed into the original thermal compound before you cleaned it the second time around. And to top it off, any chance you might have run your first set of experiments in the summer (higher room ambient temperature) than the winter?

That's not to say that AS5 is useless, and one should never buy it because it's a ripoff. That isn't the case. It's good stuff; I used it on my last two builds. My point is just, it isn't like AS5 is the Mazerati to a generic brand's Yugo. If AS5 were a car and you were comparing to generic compound, it might be like an Infiniti G35 vs a loaded Altima. Yeah, it's better, but they're both decent and get you where you want to go. One has a little more style, and a better brand name, and it might go a little faster. But it isn't exactly night and day.

Ok, first off, heat is transfered by phonons and photons. At low temps (for all practical purposes, processor temps are low temps), phonons dominate the equation. But photons also contribute. "Color" really just means "wavelength of light." But there is a lot of light out there that the eye can't see, from radio waves to gamma radiation. One way energy (heat) can be transferred is by radiation emitted from the surface. Photons. "Black" means that the surface isn't going to hang onto it's photons. As an example, think of your toaster, or electric range/oven. The coils are black (even matte black; not jet) but when they get hot, they look red or orange. They're radiating energy at that point.

Think of it this way: at high T, (really any T, but the Bolzmann coeff. gets in the way, which is way small) photon heat transfer is proportional to eT^4, where e is emissivity. For a perfect black body, e=1. If it isn't perfectly black, e<1.

i agree with you on the flat black paint thing.

this has been a topic in the automotive racing scene for years.

I don't do a lot of benchmarking and testing, but I do remember this one time, I picked up my computer and threw it against the floor, and then I proceeded to smash it, ala Michael Bolton in Office Space (but without a bat or the cool background music). I was impressed with how "cool" my CPU became!

BTW, that is a true story. No shit. I literally smashed a recently-built $2200+ system (circa 2002), because a ten page research paper I was writing (and was due within a few days), just sorta became "unreadable" in Windows Me (on the CD-RW I was using). The process of tearing everything apart (at like 2 in the morning), did a lot of other collateral damage too, including breaking a wood desk and ripping out wires from the wall.

The great thing was is that I convinced the online site where I bought the MB that I needed to RMA my board because of a few issues, and they agreed! I sent it back to them in a box with zero padding; that's because I had to include a few broken electrical components and make it look like it was broken in shipment! Classic!

You sir, have commited fraud

8O damn man.

i have left knuckle prints in the top of my old case before.

i have also shot my car stereo with my 44mag.
and my tv with my glock 9mm before. :x

Yeah, that's good.

Fraud? Fraud like that committed by the US Congress against the People and Common Sense? Fraud like the image Apple likes to portray, when they themselves are just as dirty- in their business practices and their environmental record? Fraud like those who claim that they knew all along that there weren't any WMDs in Iraq, but no one listened? Fraud like voting for a war you claim to hate because you don't want to be seen as weak? Fraud like the Duke rape case fiasco? Fraud like Windows Me? Fraud like these old farts demanding free medical care and benefits, all while knowing that the system is going to crash? Fraud like those unwed ethnic women who have five kids by three different men and married to none, and yet, get all sorts of cash from Uncle Sam?

Hmm. OK, I can live with that. But something I left out was that I had RMA'd both the MB and CPU more than once. I was suspecting a memory error (as in a physical defect), but it could also have been Windows Me itself.

Not picking on you, just tired of all the crap I see in politics, and the fickle ways of the American People.

Sorry man, i can see now that windows me was the downfall

I killed one with a grenade and would have killed another with my M1911, but it misfired, so I did him in with his own bayonet.

Sigh, now that my new rig is humming along just fine, I have nothing more to live for.

no i mean i really did shoot my car stereo and my tv.

the 1911 is a nice pistol.

I love destroying things...I remember a friend of mine, who owned a shitload of AK-47s and like a billion rounds of ammo, and I would go out in the woods on his property and see how fast we good cut down a tree by shooting at it.

But when I said I killed, I meant I killed a human being, not a computer (other than the one I mentioned earlier).

in which war?

BF 2142!

Just kidding; I was in Gulf War I.

cool, well not really.

but it is cool that it was him and not you.

Yeah, well there is this saying that I am sure that everyone has heard that says something like, "I am willing to die for my country".

Well the reality is that you don't want to die for your country, but instead, give the enemy every chance to die for his.
