cpu cooling from underneath ( i think i am crazy):)

Tux · 12-25-2001, 12:31 PM

Cooling the cpu from both sides

Is this or would this be viable like I mean if you have a socket cpu trying to find a way to cut though the board to get to one side of the cpu and cooling it from underneath it?

Then you could have a cooling samwege?

i think i am crazy this is just a quick rant cose its nearly 7:30 am

ROFL

Err..umm.. there's vital circuitry/electronics under the cpu not to mention the thermal probe

Tux · 12-26-2001, 10:20 PM

no serously

like air cooling blowing air onto it not useing heat sink or something

warp_zero · 12-26-2001, 11:24 PM

any hole you create through the motherboard under the socket will cause MAJOR damage, and you will have a dead motherboard.

lets just say, that might affect performance

Tux · 12-27-2001, 02:14 AM

grrrrrrrrrrrrrrrrrrr

i dont mean a home mod im talking like a mobo designed around it

so you have sort of backwords cooling so it has a fan in there behind and its all desinged around that

Atomicmoose · 12-27-2001, 09:37 AM

How would you mount a fan to the board?

resago · 12-27-2001, 09:42 AM

you could use a heatpipe like notebooks do.have a plate on the backside of the cpu and pipe the heat to a finned plate on the front side.

Some one did this to an old BX board or something that didn't ahve any electroncis underneet the socket, and the improvement was minimal, if at all anything

Joe · 01-01-2002, 12:33 AM

man I find that hard to believem that someone has done that.

I have Never seen a board that didnt send traces past that area. I have owned alot of socket 7 boards too... I mean I dont think they can avoid that area. Since trace length is so critical, the shortest route from the chipset to the pins farthest away from it is going through the socket area.

Also there are power planes on the different layers of the mobo that you can tell from the top or bottom if something is running past there.

it has been done, it offered virtually no gain

I am absolutely amazed that the machine worked after that... Joe C's got some big brass ones... or else its a freebee mobo that he figured "why not"

Brad · 01-01-2002, 04:29 PM

well, it was a non production board, so I am guessing he didn't pay too much for it.

couldn't you use an xray to figure out where the traces are?

Joe · 01-01-2002, 04:30 PM

Yeh, you got an extra one laying around?

Brad · 01-01-2002, 04:32 PM

/me searches my pockets no.......

Kevin does though!

I've done this with some old BX boards myself. I've found that
I get better temps, stability, and overclocking by simply keeping
the Voltage Regulation goodies on the system board cooler.
IE: keep an 80mm fan focused on the caps and stuff around
the processor. And, believe it or not, I've had some decent
results with a FEW boards by having a fan (ducted underneath)
blow air between the Mobo and the mounting surface.

But best results are obtained by cooling the regulators...
