why is heat bad for hardware

This forum is for help with and discussion about your video hardware.

it would also be handy to have a can of spray coolant nearby to cool the roasting componenet^^ itll prevent further damage^^...
not necessarily nitrogen though cuz that does cause alot of condensation...

thermal expansion ?

i would, that coolant technique is handy, but don't over do it in one go.

On-topic: A simple, 'common sense' type suggestion - make sure you have sufficient clearance around your box for the fans to operate. If your computer is flush against the wall/desk/ect. then all the fans in the world will do you no good.

An easy to do, but also an easy thing to forget.I had to remind several people in college.

As long as there is clearance on two sides (The front and back) then that is enough. The point of case fans is to pull air through the case from one side to the other, cooling the equipment in the process. Of course, you don't need a heater flush with your case though. :P

For some reason, on my computer, there's no vents on the front -- just the side and back. (Of course, I also don't have a case fan, just the fan in the power source and on the CPU.)

And while I'm at it, congrats to Corran for finally getting your SN changed. :)

Thanks. :)

It feels a little awkward though. :P

Well, if you're going to wake this thread up, I might as well point people to this monstrosity.
It goes for about $250.

C being the speed of light in a vacuum, right? Well, as an optical computer would use optics, that is, light, if it doesnt run at C then it would run close to it, a high percentage of it. Or sorry, it would be a speed equivalent to C or something, considering that processor clock speed and C are two different scales...

I dont know, so I'll shut up now.

All I meant was that you can't measure the speed of a processor in feet per second, miles per hour, or anything like that (c = 299,792,458 meters/second = 186,000 miles/second).

Instructions per second, floating point ops per second, etc. - those make sense.

Like you said...different scales.

Although light does have a vibrational frequency, thats what gives it colours, etc. So maybe it will be asessed in terms of that. Red is something like 650 - 700-something angstroms, and blue is somewhere around 400... so technically blue is "faster" because it has less distance between wavetops (not sure if that is the right word, but blue has a higher frequency than red, hence a smaller number of angstroms.)

So a computer running on blue light would kick the ass of a computer running on red light... maybe thats how computers will be graded in the future.. on colour instead of chip speed... interesting...

If the clock speed had anything to do with the frequency of light being used, then you might have actually had a point :)

I'm just saying that in a generation of oprical computers, clock speed may have everything to do with light frequency. You cant say either way, really. I'm thinking at some point in the future, so...

No, the Black Monarch is more or less correct on this one. With the exceotion of extremely long wavelengths, the frequency of the light has little to do with it. The bigger issue is how rapidly the light can be blinked on an off.
