Thermoelectric ~ 800D Case Mod (Over 1m tall!) - Page 4

Looking good,

I will be making a quad direct die setup soon, and will be using aluminium. I'm struggling to find copper blocks regardless of price, even on eBay I can't seem to find suitable copper. I'm not so sure that TEC waterchillers are the future anymore, take the coolit freezone elite for example. The delta between coolant and CPU temperatures was 45C on load. The temperature difference between coldplate of direct die and CPU seems to be significantly lower than that of waterchillers.

Do you remember the coolermaster wavemaster? God she was gorgeous, I'm tempted to mod one to allow a TC PA120.3.

I look forward to your thoughts on this matter.

EDIT -
FYI, the phobya 1080 radiator can potentially hold an i7 860@4Ghz at 28C, the HD6950 was also on the same loop. This makes me wonder if TEC's are worth the hassle and time for sub-ambient. Ultrasonic2's 2*50mm direct die could only hold an i7 920@4Ghz at around 30C.

Those numbers look off imo, no screenshots claiming frankly imposibly low numbers.

Especially for over 1.4V, I believe the cooling could keep the coolant temperature at 6oC above ambient, but there is no possible way that the CPU on load could be 6oC above ambient on liquid cooling.

I mean I haven't done a heat balance on it, but I'm questioning whether it's physically possible:

I mean looking at this, assuming that the coolant is perfectly cooled at 22oC (stated ambient in that example), which it wont be. You then have to transfer heat from the CPU through a layer of TIM, through several mm of copper to the fluid. A DT of 6oC between CPU and ambient on load sounds like a lie...

Comparatively, if your "waterblock" is sub ambient, and you work with more realistic DT values, you actually can achieve them.



My issue of course will be transferring heat through 40mm of aluminium, I don't know if it will be too much.


I have some other block designs dwelling away in my imagination, but we'll get there when we get there biggrin.gif



Also, sorry for the lack of update in a while, I'm having a bit of trouble finding a company to cut my aluminium block. People asking me for project plans and such kookoo.gif *sigh* really don't need to make it complicated...

how thick is that block of aluminium ? 2 inches ?

also are you planning on doing all the work by hand ?

43mm and I'm trying to avoid it. the cuts are too long to reasonably do with a hack saw anyway, It wouldn't be easy at all to keep the cuts straight.

I am trying to talk to some companies about getting it done, but it's pretty inconvenient.


Anyway, in the meantime my radiators arrived:

radiators_for_build_by_crabid-d3iedqh.jpg

This is how I will prob hook them up:

rad_positioning_by_crabid-d3iedqo.jpg

So I'll run the water through in the opposite direction to the airflow.

I have considered ways to let each of them flow on their own, which would be best, but all the ways I have thought of get obstructed too much. Ideals welcome ^-^

Also, I just looked at that pic and realized I kinda need to dust : /

My god, two GTX480!!

That's serious business man eek.gif


Tried with those hacksaws that have a sort of support that lets you fix an angle? Dad and I used to cut chunks of wood for supports and stuff with one and the cuts were perfectly straight, as the saw can't bend (one massive piece of a blade) and the body is fixed.


This kind of hacksaw I mean.

I remember paying like 70€ for the one we have.



If you decide to go this way, remember to keep the block lubricated, or the blade will grip the walls and won't let you go any further wink.gif

You know with a 250 watt cpu load you are looking at about a 30c delta across the cold plate ( that is very ruff )! which is really going to make it hard for your self to get good results. It's to thick and not made from the far better conducting copper.On the plus it's a billing times cheaper than copper


EDIT
oh and using a band saw would be way simpler that a hacksaw

I'm contacting companies to try and get access to a bandsaw(or mill), but if I did it at home I would have to resort to hacksaw.

I realized that there would be a large DT across the block, unfortunately, I currently don't have any other option to achieve the clearance I need.

Do consider though, With lapping I am going to lose a fair amount of metal off the block ~ probably 5mm at least IMO (there's a couple of deep scratches on it).

The heat output of the CPU wont be constant (because I sure as hell wont use a machine that uses 700W for cooling for folding 24/7 tongue.gif)

And Elloquin has also had very impressive results with a similar setup.

Oh and that much copper in a block would probably cost more than my computer... But I am considering copper for replacing parts I can get working in aluminium.


I might expand the build the include some more funky block designs that better deal with the distance from the CPU. I've got a lot of ideas wink.gif

But I want to test the simple stuff first.

@Crabid

I have a sheet of copper 360mm*280mm*10mm, If your interested I would consider selling for £40 with postage, which is less than scrap value.

PM me if your interested.
