very nice! thats the first notchannel wb i have seen which has three in/outlets. how are the temps?
cu, gurke

Very good idea with the gpublocktop! But how do you make the plexi so transparent when you run it in the mill? Mine just gets fogy...

Chrion.

First when you machine it, Use WD-40 Liberaly (SP) as a coolant.

If it still gets foggy, you can flame polish it. It takes pratice, but works really really good.

EDIT: That is sone very beautiful lathe and mill work.

Very very nice.

Have any cad pics so we can see how the water gets in and out?

Gurke my temperatures are very very good but I need to know if they are real. First I should look for a commercial block to check the mensurations of temperature of the Asus.

ChrioN the plexi after lathing him is refined with sandpaper and later with a cloth with CIF that is a commercial product to clean bathrooms and kitchens.

Fixittt alone an old lathe of 1940 :(

What kinda sandpaper? Really high grit count or is there something special about this CIF stuff?

Sandpaper 320 later 600 and later 1000
The CIF is a polisher for china, plates, cups, pots and bathroom accessories, its abrasive capacity is very low.

Comparison of temperatures Volcano 9 and block DMK-5

ATHLON XP2100+ @ (185X11) 1,75V. ASUS A7N8X
MBM 5.3.2.0---2 flat sensor thermal---CPU burn 20 minutes

DM-5
Temp. room: 22.5ºC (thermometer of mercury)
Temp. intake radiator: 21.7ºC (flat thermal sensor)
Temp. diode: 38 ºC (asus)
Temp. socket: 32ºC (asus)
Temp. core: 31.4ºC (flat thermal sensor)
Temp. H2O: 25ºC
Delta core / room: 8.9ºC
Delta core / H2O: 6.4ºC

Volcano 9 (4964/4687 rpm)
Temp. room : 23ºC (thermometer of mercury)
Temp. intake radiator: 22.9ºC (flat thermal sensor)
Temp. diode: 70ºC ??????? (asus)
Temp. socket: 40ºC (asus)
Temp. core: 47.5ºC (flat thermal sensor)
Delta core / room: 24.5ºC

More than 185 x 11 with the volcano 9 the system becomes unstable

Is that good?

pardon my n00biness, but could someone explain the working principal behind the block and the water flow etc?

Im guessing the water comes in down the center, but it is just a guess. :shrug:

ChrioN
3 tests with the volacano and 3 tests with the dm5 in 3 different days, the variations are minimum.

Ahhhhhh, right. I didnt see the slots in the central section.

Thanks aitor, nice work there. :)

aitor, sorry to ask this in your thread but i had to :P

Fixittt, how do you "flame polish"?

Pardon me for intrusion, but this is how I do it:

Sand the edges to the max grit you can find (I do it to 600 wet sand paper) and clean and dry the pieces. I use pencil butane torch for this, it needs a directional thin flame to succeed, use the torch along the edges in long moves (like painting), not keeping the flame on one place. Several passes with torch and all the little scratches are melted and cooled into a nice, see-through, flat surface.

It surely need practice (which I still don't have:D ), but pls, Mr. Fixittt, pardon me for intrusion, and pls. give us some more tips!

Cheers!

chrion
wet sandpaper (600+) then autosol or some other finishing product will make your plexi transparent ;)
