What if they made a GOLD SLK-900

[User1001]

you'd have to grow the diamonds.

They've already started doing it. Maybe intel can use it on their 100+ Watt Procs instead of stick you with a loud 4200RPM and a poorly designed Copper/Aluminium Hybrid Heatsink

theres still the interfacing between the proc and the heatsink, not to mention Intel's little IHS ah heck and the core itself...

that would REALLY cut down on temps, you know.

You guys need to stop fantasizing about gold's properties. The ONLY reason people use gold wiring or gold interconnects on audio equipment and the like is because they DON'T CORRODE! Gold is quite inferior when it comes to electrical conduction AND thermal transfer. Silver obviously is best, but it is very expensive compared to copper, and it oxidizes like mad.

My two cents

haha i had to tell that to my techlab teacher that was telling everyone monster cable is the best because the gold on the connection has the best electric transfer.....
and i told him that it was because it doesn't corrode, and silver/copper has better electrical transfer...
everyone just told me to shaddup...
a few days later, he looked in his book, and corrected himself...

lol you should hear his bullshit about computer stuff...

He buys Monster Cable? What a noob!

 

[henry332]

Yeah, that would be one hella heatsink.

I had a friend that designed a gold heatsink for a 1U heatsink and it cooled the cpu 28degrees better than the stock cpu cooler he had

then he failed you =D =P

Gold is acutally better for connectors because you get a better interface, the bulk properties are not that important since it is a very short distance but it is easier to get a good electrical contact between two gold surfaces than two copper surfaces (copper is really bad since you always get a thick oxide layer on the surface).
Monster and other low-cost brands use gold but some more expensive brands acutally use more exotic materials such as rhodium for the same reason.

Well i realize that a diamond heatsink is out of the question...price, finding a big enough stone to cut a diamond heatsink out of, etc... but why dont they make a thermal compund with shards of diamond in it. I mean they make one with silver chunks in it because oif silvers great heat dissipation. Why dont they take that same idea and apply diamonds instead of silver. If that were to happen that would make one hell of a thermal compund. Now they just have to find something htat will shred diamonds to the size of dust...always wishful thinking

Good idea

 

[FrenchTickler]

how about a potato heatsink or liquid nitrogen cooling or a fog machine inside your case with random colored halogen lights going off


I'd personally like to a put a stripping pole in mine and have a minature britney spears with the disco ball idea

The best thermal conductor known to man does not conduct electricity at all. Thats right, this forum should be named "What if the SLK 900 where made out of diamond". Diamonds currently transfer heat better then anything else and, are cant conduct electricity.

Doped diamond semiconductors have been grown, however, and have run at 81GHz, so directly growing a diamond heatsink on top of a diamond chip would be a neat idea. Although you still won't get the heat dissipation that aluminum can give you, so you'd probably want to use the pure diamond layer as more of a heat spreader. Part of the reason why diamond can't dissipate heat well is that it has a very high heat capacity, so it'll just absorb the heat. That is a good thing, but it's a good idea to be able to dissipate the heat as well.

There's already a thermal compound that has diamond particles in it. However, it's not the best. Some compound called Shin Etsu (IIRC) something or other is the best right now...

 

[Howard]

How about this: Installing all the hardware, cleaning EVERYTHING, then growing a huge-ass layer of diamond on top of it all.

Sweet, no?

 

[Howard]

Then again, the components probably wouldn't be able to survive the heat and temperature.

I keep seeing this "fact" posted, but I've so far not been able to find it in any reference text. At the temperatures most electronics operates at, the only property of the material that is relevant to heatsink performance is 'thermal conductivity'. There is no mystical 'dissipation factor' that makes aluminium better than anything else. This is why copper heatsinks always offer better thermal performance than an identically sized and constructed aluminium HS.

I accept that at high temperatures (>100 C heatsink temperature), black body emission does become more relevant, but it even then it is tiny compared to convective heat transfer.

Now, if you want maximum thermal conductivity then nothing comes close to heatpipes - it's possible for a HP to have a thermal conductivity 20 times better than diamond. Because HPs can't be cut to any shape, they are often used as heatspreaders to transfer heat from just above e.g. a CPU core to fins further away.

Don't you mean conductive heat transfer?
