distance..

[[B]attery]

ok, i've got kind aof a project on paper going and before i attempt it i'd like to see if anyone knows if the length of the pins on the processor effect speed? if i increase the distance the data has to travel by say...a foot. would i have a problem with signal? would i lose speed? if so how much?

[Turok]

It's the speed of light :stick:
It's impossible to see a difference in response if the projector is only a few feet away from the paper.

..."length of the pins on the processor"...
What do you mean with this? :confused:

If you're experiencing some delay with the projector, it could be the projector's response time, the distance of the video cable (the longer, the weaker the signal), or there could be some other factors for the lag, but I dont know because projectors are not ofthen used as a PC monitor.

[[B]attery]

its not a projector. its a project than i'm designing on paper...sorry for the confusion.

[WeStSiDePLaYa]

you wont be able to do it. interference and signal degradation will prevent it.

[[B]attery]

how bad is it? there has to be away around it.

[craig588]

You can help it will lots of capacitors, but a foot is long way to go, I don't think the longest traces on most mobos reach a foot long.

Really? I figured prolly 12-14" max.

[[B]attery]

hmmm... well next question... do the gases in phase change systems conduct electricity? in gas/liquid form?

[craig588]

Some of them do, some of them don't. Name some.

[[B]attery]

freon...ammonia...i'd rather use freon.

[ferrari_freak]

You've got me curios, what is this project you've got going that you're asking questions about and won't tell us what it is? Spill the beans mister :banana: .

hehe, i'd like to keep it a secret for now. lets jsut say its going to keep things pretty cold.

attery']freon.

That's a brand name.


I already know what he's planning and it's not going to work on so many levels. He also doesn't have the facilities to pull it off if it worked in theory so he's just wasting our time. I just really wanted him to present his great idea and then destroy it, but he's holding out too long on his dumb stuff.

He want's a put a die inside of the phase change system and not deal with copper being so inefficient. Of couse because I said that he's going to have a different idea, but I'll pretend for a while longer.

[STEvil]

really depends on the setup...

Slot 1 boards had traces from 2" to 14".. Slot A the same, but nothing "fast" currently does that I know of..

[[B]attery]

heh, that is actually my idea, although i've already gotten around the signal issue. now its all about getting a gas that doesn't conduct eletricity... and btw i do have th facilities to accomplish this. i have access to an hvac engineer, a precision machinist, and the rest i can do myself. moving the processor away from the motherbaord was only going to be to negate the condensation issue, but i've found a better overall way to do it.

Buying a dell? :D

ummmm no.

Copper isn't just serving as a transfer medium, it's increasing the surface area of the chip. There isn't any gas I know of that has the capacity to cool a die, there isn't enough surface area. It's going to heat up the gas faster than it can cool an area that small.

Also, copper is so effeciant it barly matters.

I'm glad you're matutre enough not to change your idea. (There's no sarcasim there and I hope you stay around)

[[B]attery]

heh, i've been around awhile actually. i jsut don't post too often here. i was on staff over at virtual-octane.net, but nuclear (the owner) shut it down. what i'm working on now is designing a box to seal the socket in and then allow the actual phase change to occur in side the box. it'd allow for direct die contact. flow would be an issue.

[[B]attery]

i'm still in the search of the right gas for the project.

[tennvols_69]

it would not work, ive actually thought of this idea when i first got into phase change. i had a water block back in the tbird days that sealed to the chip, which got me thinking. the main reason that it will not work is that the heat and small die surface, when it comes in contact with the liquid freon will boil into a vapor creating a pocket of just gas which will not have enough cooling compacity to remove the heat created. and for another thing the seal to contain the gas will not last you will eventually have a issue with it.

[[B]attery]

that all depends on how you seal it.
