Hello ocn I'm doing a quad Peltier direct die for 775 ( go on laugh it out...), I am going to use 4x 154watt Peltier at 12volt 8amps for a total of 12volt 32amp, Not for ultra low temps but at least room temp under load, I'm going to make my own aluminium water block just using a drill press and simple tools, yes copper would be better but I'm doing it cheaply, The water block will be 100x100x15mm and the cold side will be 100x100x5mm so its just keeping things simple and yes I know about Peltiers and I know how much heat I have to cool that's why im using 1 240mm rad push pull and 2 120mm rads push pull

that's all I got so far waiting for my bits to turn up!

I can't wait to see results

This should be good, hope it turns out for yah

 

[lzf995]

thanks mate

maybe ill have to ( test ) one of them controllers when you finish them

 

[Ando]

Nice - was allways meaning to do this until I got my SS, wasn't any need after that, still very interested to see how this works for you

Good luck

 

[lzf995]

Thanks Ando just waiting on parts

then this build can start if it works or not

 

[Puck]

Good luck! Can't wait to see it finished.

You may need a lot more rad - direct die setups are a pain to keep the water temps down since you have all the heat from the TEC's plus the CPU in the same loop. With a 360+280 in series with high speed Delta fans I was still seeing >10c water-ambient delta with only one TEC on a 3770k. Since TEC's work on a delta, water temp is CRUCIAL on a direct die setup since as the water temp goes up, so does the cold plate.

Four of them plus a 775 quad will be a TON of heat in the loop - I'd be looking at quite a bit more radiator then 480mm worth to keep the water temp down in the loop

.

i know ive already don't the maths a while ago, and yea I was thinking that the 240+ 2x120 rads will work for just testing with out it on the cpu till I can find another 240 rad thanks

I was also trying to aim at 30*c delta to leave me in the teens with 200watt load with tecs at full power as anything will be better then like 50*c under load haha

also ill do some tests, watercooling vs direct die just to see if its good enough

ill use the same rads and pump

100x100x5mm for the cold plate probably will have substantial issues. You will be cooling a lot of area that won't even be in contact with the heat source. On top of that aluminum does NOT conduct heat very well, so the chance that you get a good result here is dwindling. I'm sure you'll find this as you get going, but good luck.

thanks and this is just a prototype before I do copper just want to work it out with waterflow ect and it'll be insulated well

also ill try my 400watt peltier to see if I get much in provement between them

 

[Panorama]

Lookin good

 

[lzf995]

Thanks will update soon waiting for my bits still

 

[lzf995]

240mm rad turned up

 

[lzf995]

right my list for later

drill waterblock and get the coldplate to line up and screw tigh

then hopfully when im home home the rest will be waiting ( peltiers and powersupply

 

[lzf995]

lil update just drilling my waterblock

pics soon

 

[Panorama]

Nice

I just ordered my TEC and powersupply today. Where did you get your copper for a coldplate ect? or did you buy a plate?

 

[lzf995]

im using aluminium hot and cold

and ebay.co.uk lol and good

 

[lzf995]

got my aluminium block drilled

need to finish it now with some bolts to fill the holes haha

its has 8holes in total

then ill update with some pics when I get home when I have the lead to my phone

also im not going to go for ultra low temps now! just better then water cooling like room temp under load

with 200watts wich I worked out 90watts of power with 4 154watt peltiers to get mid 30*s

about 250watts of heat to cool a e8500 at 4ghz

hahahah! you wouldn't be saying that if you saw it
