super high-res pics/technical infos LP B request

Hi dudes.
Im having bad overheating problems, because for silent reasons, my case lack any ventilator. I still want reasonable overclock. With all my heatsinks ( http://ax2.old-cans.com/show.php?p=b...3&c=8&d=1&v=v2 and http://ax2.old-cans.com/show.php?p=w...4&c=8&d=1&v=v2 ) I did not managed more that 200x13 - and it's still only stable for about 4 hours of Prime95 torture test of CPU, then it freeze.
I even added a heatpipe, connected to the case by cooper holders ( http://ax2.old-cans.com/show.php?p=b...2&c=8&d=1&v=v2 ) to reach the 2600Mhz with 1.800Vcore (AXP-M 2600+), but I want it to be stable for longer time - it means cooling.

So, I decided to WATERCOOL the mosfets. Both. This is my CPU mosfets thing:

http://ax2.old-cans.com/badthingshap...ercooling2.jpg

It is not supposed to cool very well, only adequately - the working temperature about 50-60C is healty for the mosets, after all :D ;)

Now I got stuck. I need to cool the mosfets on the dimms too, but there are very limited space, only about 14mm high space is there, when there is a full-sized GFX card. ( http://ax2.old-cans.com/show.php?p=w...5&c=8&d=1&v=v2 ) So, now what.
After I added there this heatsink - I glued it with Arctic Silver expoxy http://ax2.old-cans.com/show.php?p=w...d=1&id=106&c=8

I can't take the need measures for making a watercooling cooler of the mosfets, voltage regulator and SB all by myself.
Therefore I need HELP :(

I need a super-hi res (maximum size/quality possible) photo of exactly THIS part of DFI LP B mainboard:
(the correct 90 degrees vertical ange when taking the photo is critical too, the lens distortions can be corrected in PaintShop, but the ange has to be 90 degrees - right from the top...)

(at the left the AGP slot, at the top the end of dimm holders, at the right the second of the third capacitors below the rams and at the bottom the corner of the SB chip)

And I need to know the height of the SB chip itself, the voltage regulator and the mosfets.
Also the dimensions of the SB chip itself won't hurt. They should be 28x28 mm (that's the size of the original SB heatsink), but at least a confirmation will be very much welcome.

The best way will be a actuall technical blueprint of the board, just this part, not the PCB layout, just the dimensions of mosfets, voltage regulator and SB chip AND the clearance between them and the closests limiting objects on the mainboard - again, the AGP slot, at the top the end of dimm holders, at the right the second of the third capacitors below the rams and at the bottom the corner of the SB chip.

In case of picture, to make the picture usefull - a measuring 1x1 mm grid has to be printed on quality laser printer (1200+ DPI) and placenb etween the SB and the mosfets - more precisely, the voltage regulator rather - this one is most down thing on the mobo.

There is a suitable size 1x1mm grid prepared:

http://trodas.wz.cz/grid.eps
http://trodas.wz.cz/grid.pdf

Again - I can't take these measurments for myself, because I glued there the heatsink to get stability and I have to give my friend who make the cooler the blueprint for the cooler first, so I could just replace the heatsink with the WB cooler and my machine stay working.
Making of the thing could take week, so "destroy first" is not a option.

Also considering that:

CAUTION!
Arctic Silver Thermal Adhesive is a permanent adhesive. Components you attach with Arctic Silver Thermal Adhesive will stay attached forever.

...it maybe end with buing a new mobo, just for the watercooling experiments. On behalf of owning two DFI LB P mobos I would also urge DFI to reconsider giving my the need measurments and cut the bull*hit about NDA when talking about dimentions, that every user could measure for itself.
(everyone, except these, who glued a heatsink permemently there, that it is...)

Currently Im only aware that the original heatsink for the SB measuring 28x28 mm - so I quess that the SB size is 28x28 mm, right? Anyone dare to confirm this and tell me the height of the SB chip? (W/O the heatsink, that it is ;) )

Okay, let me make VERY clear what I looking for:

http://ax2.old-cans.com/LPBdimmWB.gif

Now this is easy to understand, yep? ;) :)

easy to understand - great images, it's a shame I cant help you

I don't think many of us are using that board, however - I may get an ultra infinity soon - would that work as they're supposed to be the same? never the less - you should ask around, if this is your only thread, because I doubt you'll get a response here

DaGoof - thanks ;) Becuase when talking with DFI suppor persons I feel I talking spanish to them, or something... :( They for absolutely obsure looking (to me, at very least) reasons refuse to give me ANY info about just damn components size/their clearances on mobo. I lack of words to express my feelings about it.

Anyway, yep, Infinity will do it as well. The mobo only got red PCB and except one chip (the gigabite network) are entierly the same, so - it would help as well, thanks in advance.

Meanwhile I took my second testing LP B mobo and measured what I can. The SB height, size and dimensions I taken from Epox 8RDA+ mobo, so... I think the SB chip is the same. Maybe just knowing who make the mosfets/voltage regulator could help - the technical specs must include the component size, and that will do it.

Anyway, my results so far:

...the thick doted red line indicate the waterblock bottom plate first design. On this, with 15mm clearance from AGP full-size card I planing add U shaped cooper tube and that should do the cooling ;) ...if, and only IF i could get the chips dimentions... :(

...anyone get a idea, what the "I" on the chips meant? Could this be Infineon...?

It could help me with obtaining the specifications of then, that include their height :)

A big thanks to stealth17 for most measurments:

...and a nice photo from him!

:D Getting closer! :D

Recently I get hold on killed DFI LP B mobo (poor user pulled by the heatsink he had on the Vdd mosfet (yep, the one powering the NB) and ended up like this: http://ax2.old-cans.com/s.php?p=badt...1&c=8&d=1&v=v2 ) so I took the oportunity (heatink from SB already removed) to finally measure what I asked so many times DFI support with "great help from them" by myself :D :p:

I simply like to finish things, so, there we go - measurments:

http://ax2.old-cans.com/LPBdimmWB5.gif

And final design of the main bottom plate of the Vdd + Vdimm + SB waterblock for DFI LP B/Ultra Infinity:

http://ax2.old-cans.com/LPBdimmWBfin.gif

So, now anyone with access to 4m cooper plates and CNC cutter can build one :D ;)

But w/o exchanging the caps to better ones - don't expect big improvments, tough ;)

/me off to get mosfet Infineon 09N03LA in TO-252-3 packaging ( http://www.necel.com/discrete/images..._to252_3zk.gif ) witch very well could resuscitate the mobo :D
