Hey guys... this is what i see from the whole discussion.... are you seniors here to fight or to make something useful of this discussion. Lolhalol, dont make assumptions, clearly listen and understand Shawty with what he is trying to say...Anyways icon_rolleyes.gif

erm..it might be not right to u guys,but since minor vibration will disturb the heat transfer,so izzit now where the thermal paste do the job?

Thermal paste only gives the medium for heat transfer bro. It doesnt help in anyways to damp any vibration... and my post earlier is edited... so ignore it

ya..but wat i mean is when bad contact occur,at least thermal paste help out abit smile.gif

Hmm well, depends on what you mean by bad contact? Bad contact like there is no full contact etc? No, it still wont help even a bit because the what really helps is not the thermal paste but the contact itself, even if u use the best thermal paste around and there is bad contact, u r still going to expect a bad heat transfer, because imagine that u have a 1mm differential between the nb core and the cooler core, in thermodynamics, 1mm makes a lot of difference.

Having the thermal paste actually just gives the ocean for the ship to swim, refering the ship to heat. Maybe if there is a strong adhesive like the arctic alumina(im not sure) that sticks the core with the cooler then, u will get maximum benefit from it.

minor vibration wouldnt coz bad contact like 1mm differential smile.gif

Well, of course not at the human eye lor, bad contact is imminent if there is vibration, and of course we cant see vibration occuring in front of our eyes, but temperatures can tell and performance also can tell. Ok, Take an example, lets say u losely fit a Chipset cooler on your NB and of course u put a thermal paste on it, But since u r moving t around, as it can happen sometimes, a bad contact occurs, though thru rough eyes it seems stuck. Now when ou are overclocking, would u notice a difference? i think you would, coz of the bad contact.. due to vibrations or movements you created earlier on.

1mm is actually a big space between two contacts, coz u can use a ruler and check...its substantial for a disturbance in heat transfer.

u r mentioning losely mounting + vibration but me is proper mounting + minor vibration smile.gif
but still..wat u say is true in this case where the thermal paste is useless

Hmm proper mounting and minor vibration, still the thermal paste is not a significant contributor... the only significant contributor here is the contact...between the core and the cooler:) And if there is any form of vibration, it would not affect normal comp users, but in high performance or overclocking. Vibration by fans can be annoying. My verdict, passive cooling with a copper core and aluminium fins.

I'm being fair by saying he didn't imply it.

He's right, vibration can kill contact which in turn results in higher temps, not by alot, but still, it exists, and it does disturb the channels and filling created by thermal paste. About the X38, he is also correct, as you get more surface area, force is distributed more evenly and thus there's less disturbance across a higher area. Newton's law at work (what i believe he's trying to imply). That's why even though newton's law dictates that for every force there is an equal and opposite force, a man can fire a .50 BMG without getting his arm ripped off, because the acting surfact area for recoil transfer is that much higher, although the kenetic force is still the same. Note that this applies to 2 solid bodies assuming linear oscillation.

Point is that I win.

Anyone who wants to lawan can take it up with Pak Cik Fourier  laugh.gif

I do agree with what empire23 has said about the first few sentences, but hmm using newtons third law as a point of reference is probably not the right analogy to use.... because if you are working on newtonian dynamics to explain heat transfer then heat that hits on the copper sink should bounce back to the NB die, now thats third law of newtonian dynamics on heat transfer. You should use the principles of thermodynamics or the principles of heat transfer between metal composites.. i would suggest as reference, i might be wrong.. but newtons laws are quite clear cut.

i find cooler master blue ice 2 to be a decent performer... at the moment using it to cool my hd2600xt laugh.gif

i would think it would be more expensive than rm50. Coz heck, the blue ice2 is already rm65/ so i believe something like enzo would be around the same price as thermals..

yes everest can but depends on your board whether it has a sensor there or not

nop i think the pwm temp is the temp of the mosfets beside your CPU. This is my guess. Correct me if i am wrong.

its for sale at the moment, but well never really checks temp on NB coz my mobo doesnt have temp sensor on the NB. By the way its good enough to support as a GC cooler for my hd2600xt on stock speeds. Its decent enough
