different heat sinks has different designs,
there are tubes running thru the heat sinks, it can be air or water to carry away heat.

The fins mainly are to increase surface area of heat convection,
a blowing fan means to incur forced convection.

Why water cooling, because water has higher heat capacity and thermal conductivity
to take away the heat,
but some people worry that, in high humidity ambiance,
too cool of the heat sink may condense vapour, and the water formed may drop on your
board to cause short circuit. :D

Your posts are not relevant to the original topic and resemble more the style of a personal blog. Please don't post such posts.

I explain what I can understand about cooling mechanism,
indeed, those manufacturers who make efficient heat sink, better than intel or AMD's original heat sink,
their products are meant for overclocking for CPU enthusiastic.

If not for the purpose of overclocking, why people buy new cooling equipment for their CPUs?

The motherboard also designed and its Bios programs also written to enable overclocking,

We can overclock cpu safely,
but make sure you keep it cool, not exceeding maximum temperature for too long.
60~70 degree celcius is safe when it is fully loaded.

sigh....
I give up. you are going to fry your processor.

Not true,
there are forums of overclocking,
experienced people will teach you the Safe ways to overclock. :D

Right, and you will ignore their warnings just as you ignore ours.

See this, 6.6GHz.

Can I suggest you go and learn from them then? But please, whine to those experienced people on overclocking forums when you fry your hardware, OK? Do not post a thread here that your hardware is fried. You seem to know better than people here on LQ so good luck.

15% overclocking will never fry it.

A blanket statement like that is just dumb.

If the heat sink isn't properly applied it could fry with default settings.

You should really stop talking. This is why overclockers have a bad name. You really haven't said a thing worth saying and if someone actually believed you they could do serious damage to their machine.

I agree, if you can do everything out of the box, do not need to over-clock your cpu,
but make sure the heat sink and fan can keep it to optimal temperature. :D

What a load of rubbish. You will NOT get condensation on normal water cooling systems. The only time it can happen is if you are running a chiller of some kind that drops the water temp below ambient.

Noise reduction, possible lifespan extension, fitting/custom case issues, appearance, and probably other stuff I havent thought about.

Wrong. 60-70C is fine in most cases, but not all.

Voltage and frequency will also play a part.

You dont get this, and I dont think you ever will.

Wrong again.

1.836v. Various other issues with that screenshot. Get real.

future_computers is about as much of an overclocker as someone trolling a windows forum with a linux liveCD they just d/led (and have about zero understanding of) is a linux kernel developer.

May I know higher or lower voltage supplied to the CPU will cause what difference?

Anything to do with its performance?

@future_computer: I unsubscribed from this 30 posts ago as I think you are trying to learn how to design a fast system by annoying people who are offering their time to help. Don't worry, I'll unsubscribe again, I just thought I'd mention my recent little episode to give you an idea what you're up against with overclocking.

AMD Athlon 32 bit @ 2.078Ghz (166Mhz DDR bus, 12.5 stepping), on PC 2100 memory. I had upped it to 13x stepping, and didn't really count it as an overclock. I swapped the memory for 2G PC 3200 ram instead of 1G (2x512MB --> 2x1024MB) and the box was noticeably slow, although nothing showed as using cpu in 'top'. If I typed fast in a terminal, it didn't display stuff until after I stopped. Do something in Openoffice, and it would take 20 seconds redrawing the icons across the top.

Slowed it to 12.5x stepping (NO overclock) and the box is twice as fast. It seems the faster PC 3200 ram somehow wasn't responding as fast (Maybe a logic level thing?) and the box was adding wait states or fresh addressing (= 6 cycles). Goodbye.

CPU manufacturers make it possible to overclock their CPUs,
it is a marketing strategy too,
because they know people want to play this game.

If you know your CPU's threshold, within that limit,
do your overclocking.

If you have enough money to change PC from time to time,
you are rich,
you won't care the cpu's life is shorten,because in 2-3 years you will change computer.

This is your right, your fun,
nothing wrong!
