SLI TEC Cooler

[blander]

I make some new blocks for 50x50 sized tec's.
The blocks are finished, now I have to wait for the tec's.

A picture says more than a 1000 words :cool: :cool:

Whats the third hole for?
Very nice work BTW :D

the middle hole is the wather input and the other two are outputs, but i need some more plugs

[Jochenp]

Like the whitewater cpublock?
Does this increase flow or pressure or why do people make 1 input and 2 outputs?

you have a better flow on the whole cool-area...

Looks awesome, but how will you seal the two halfs of the waterblock ?

[Kunaak]

its about time someone took a look into pushing the design of videocards to the next level.

channeling water has been around for years on CPU blocks, but the idea seems to have been completly ignored on videocard blocks, instead always opting for making the same block over and over.
I am glad to see someone took a shot to make something more unique for a videocard finally :D

Mostly because it keeps things simple. Plus people like to use a channelled waterblock and route one hose to vga and one to chipset then recconect everything at the res. Of course it works better to channel but you add an extra hose to every block with two extra fittings (one at block and another where they join back up) and every extra fitting means extra potential to leak. Some would say this overrides the benifits. I say if you have the space for the extra tubeing then do it cuz it'd look badass.

[D_o_S]

Mm, I like!!

[alexio]

Nicely designed and made. I have some pen drawings of exactly the design you made, but never put it in practice.

It will work very well ;)

[menlatin]

so.. that weighs how much? 2 lbs you say? If i were you i'd have gone with a delrin/acetal top. Thats alot of copper you got there. My 1900xt with homemade block, swiftech m14's, and 5 homemade ram sinks for the vregs my card clocked in at 1lb 6oz. But.... That is some VERY ncie work. Im trying to learn Bob-CAD right now so i can use the cnc at work to make me some blocks.

thx man, i hope so also...

[blander]

thx man, i hope so also...

last week i receive the pelts, but they are the wrong ones.
i need 50mmx50mm pelts and the received ones are 62mmx62mm :slapass:

hope i can change the tec's

edit: the right modules are shipped to me :)

yesterday i received the correct tec's
i hope i can post first results in about two weeks, because this weekend i am in germany, so i can't work on this project :fact:

[Mr. Tinker]

Oh awesome. How did you machine these ladies?

I think that the dual outlet design is not really needed here, and in most cases is made moot by the restriction caused by the "Y" connector.

[yngndrw]

but how will you seal the two halfs of the waterblock ?
:banana:

[C_B]

perfect work, some OC-results ?

[cool_dude]

Really nice work you done there, as above.... results? :cool:

c_d

[G H Z]

I could use a couple of these, 226W Tec's I assume :banana:

Really nice job!

[n00b 0f l337]

320 watt power, 226W movement.
I'd prefer 350watt 62mm's...

i will use a tec with qmax = 418W

but i will run it @ 12v:
Qmax = 232W, Pmax = 192W, dTmax = 55°C
dT (with Q = 100W) = 27°C

or @ 17v
Qmax = 290W, Pmax = 357W, dTmax = 60°C
dT (with Q=100W) = 37°C

[Jochenp]

Wow, where did you get such a TEC? are you sure 418W is qmax and not the total wattage?

[MaxxxRacer]

looks awesome. a bit of a pain to tube, but great none the less.

if you could increase the pin matrix density and decrease the pin size, you would greatly benefit yourself. Also make sure that the pins touch the roof of the top half of the block or else you will loose alot of performance from blow-by.

ditto

yes i'm sure.
the max rating is:
Umax = 24V, Qmax = 418W, Pmax = 720W, dTmax = 65°C
dT (with Q=100W) = 50°C

[Duh]

What PSU will you be using to power up those ladies ( TECS) ? In case you´ve already stated this, I beg your pardon but I have not spotted any place in the thread where it does mention it.

Keep it up swiss guy ( I am swiss too :D) looking very gorgeous.

[ls7corvete]

yes i'm sure.

Umax = 24V, Qmax = 418W, Pmax = 720W, dTmax = 65°C
dT (with Q=100W) = 50°C
Yea but where can we get these?

[D_o_S]

yes i'm sure.
the max rating is:
Umax = 24V, Qmax = 418W, Pmax = 720W, dTmax = 65°C
dT (with Q=100W) = 50°C

oO look at Pmax... talk about efficiency now...

[Mr. Tinker]

yes i'm sure.

Umax = 24V, Qmax = 418W, Pmax = 720W, dTmax = 65°C
dT (with Q=100W) = 50°C
Please share your source. I'd like one of these if they're 50mm.

[Butcher_]

What are you using to sink the 900+W off these?

Also, ouch at your electricity bill. ;)

i allready said, that i will run these tec's

@ 12v
Qmax = 232W, Pmax = 192W, dTmax = 55°C
dT (with Q = 100W) = 27°C

or @ 17v
Qmax = 290W, Pmax = 357W, dTmax = 60°C
dT (with Q=100W) = 37°C

so the efficiency will bee not so worse...

[Butcher_]

Yes...
Pmax = 357W x2 = 712W + 200W for the GPUs themselves gives 912W.

So to restate my question
What are you using to sink the 900+W off these? (i.e. what cooling system)

sorry, i use a evo1800.
i hope that it will be big enough :)

[Butcher_]

Big rad. Only concern with it all would be the small tubing size.

[blander]

today, i run the tec the first time:

done

Looking good!!

blander - when do you test it on videocard?

first temps with my new thermometer:
please note that my radiator run without fans...
of corse, final i will run it with some nice fans

Awesome job man :toast:

[n00b 0f l337]

Whats water temp?

[blander]

does i have to flash a new bios for running my 7800gt @ subzero?
@ 2d mode i haven't any problems but when i start a benchmark, the system frezing

[madgravity34]

The 7800 did have a Cold-bug issue. It could be the core or driver verion. Update to the latest drivers and see if that fixes the problem, if not, I would google viperjohn and send him an email as he can tell you what to do.

[Weee]

you can use Nibitor to mod the BIOS to turn off the temp sensor.

Also, on my 7800gtx when i got colder than about 0C, I had to set the geometric delta to 0, don't ask me why, I don't know.. but that's how it was.

GL!

thanks for the tips, i will try it as soon as posible

[blander]

some more pics:
the temp-probe on the backsite of the videocard gave me a temp of -3.5°C to -2.5°C in idl

Whats about load temps?
Good luck!

[blander]

Good luck!

as you can read in a previous post from me, i have problems with the card...
when i start a benchmark, the system hangs up, i have to flash a modded bios
i will post load temps asap

[Mastactor]

That is stellar work Blander!! I soo bad have wanted to do all that you have done for quite some time now, I am very impressed!
Might I ask, What are the dimensions of your block and cold plate?
