4 x 172 watt pelts directly cooling the CPU

Miss_Man · 02-26-2002, 12:27 PM

Heh was bored and so came up with this idea. Since pelt stacking is a little difficult to get to work due to the fact that the waterblock may probably get overwhelmed, I was thinking of trying a 4 X 172 watt gig directly on the CPU. Due to not having sufficient space around the socket, I've came up with a triangle coldplate idea. Take a look here

The cold plate of course would be completely insulated with neoprene especially the air space in the middle of the triangle. The angles of the triangle can be calculated so that the rig can clear capacitors.
Heh maybe my next cooling project, though I need to find the funds for it.
What do you think?

Or a T cold plate like this?

i would definently go for a cube type. big fat cube coldplate, w/o air inside. musch easier to use. but it does require 4 waterblocks.

I like the T idea, with the I of the T being slightly larger than the die. the bottom of the T not touching the core could be steal or some other metal of less thermal conductivity. that way the cold would not be spead to where it is not needed. this would also simplify insulating the thing if you only have to worry about the pelt section of the T.

resago · 02-26-2002, 03:58 PM

I guess what I was describing was an I shaped design with an insulated base.

Brad · 02-26-2002, 04:25 PM

The T idea would probably cool a bit better, with two seperate waterblocks.

Easier though would be to get an 85mm x 85mm coldplate, screw into the bottom of it for mounting, put 4 pelts in it, then have a series of screws going around it to hold the two waterblocks down

Miss_Man · 02-27-2002, 01:02 AM

Would there be space on most mobos for a 85 x 85 cold plate?

Brad · 02-27-2002, 02:59 AM

no, what mobo is it? quite a few will, but more won't...

Miss_Man · 02-27-2002, 05:08 AM

Then I would choose to go with the T-coldplate most prob.

Brad · 02-27-2002, 03:00 PM

make sure the T is at least 15mm thick or so to transfer the cold from the pelts down to the cpu

Seaspray · 02-28-2002, 04:57 PM

You need a solid cube cold plate made of silver with one side directly on the cpu leaving five sides avalable for peltier 122 watt chips. Five water blocks fastened, one over each chip. ALL FASTENED DOWN WITH SCREW DOWN CLAMP.

Brad · 02-28-2002, 05:02 PM

copper will be fine, silver is like 10% better at 10 times the price. if you pay for the silver, I'm all for it of course

GigaFrog · 02-28-2002, 11:44 PM

One advantage of the T is that you could clamp the 2 WB together without touching the T (cold sides). Less heat loss by conduction through the screws.

If you could build some kind of T shapped heat pipe, with the hot side sandwiched by the 4 pelts, and the cold side against the CPU, that would be the ultimate.
(just dreaming).

Miss_Man · 03-01-2002, 03:44 AM

Heh Gigafrog, the thing is already complicated as it is, but that heatpipe idea would be really awesome if I could implement it.

Brad · 03-01-2002, 04:00 AM

heatpipes are way too complicated, you need to inject the exact amount of gas, make sure there is no air in it, etc. it isn't something to be done at home
