Scratch Build – In Progress Project: Blue Horizon - "MOTY" Nominee

nice work !

 

Yes, it looks good, but I'm one of those who don't get how you will deal with fluid overflow from one channel to it's neighbouring channels. Liquids will travel the shortest possible way, so what will you do to stop it from doing that?

 

Sweet!

 

Thanks everyone

With the power of screws and the speed of the coolant , because the channels are so wide and the acrylic is screw down so tight only a few small amount of coolant crosses, as seen in the update below.

Thanks LooseNeutrak


Now to the update:

I still haven't received the LED's for the top panel, so I've tried to keep busy with the heatsink. Today I made the angle barbs:

I first roughly cut out some aluminum with the slot saw:



I then used the facemill to get the perfect size and reasonable finish:





I then drilled and tapped to holes:



Both cubes were then sanded with 240 wett & dry:



Then the finishing touch of polish:





I'm waiting for a tool to finish the angle barbs. I went for a quick polish in only one direction to get that brushed look.


I then hook up the heatsink to my current PC is give it a test :





I've also added a few more screws and I'm sealing to screws for rubber for now:



While playing supreme commander 2 in the 1920 x 1080 resolution it topped out at 45C while passively cooling and an awesome 31C with a 12cm fan:



With my old radiator I got about 55C on Supcom 2. And idle temp is 29C with the fan.

 

Congratulations, seriously looks & performs awesome, totally rocks .
If I was into water cooling & wanted a rad I would sooo want one like that, it's like a giant cpu block . +rep

lol got carried away from the awesomeness of the functionality of it yes those angle barbs are very very nice too .

 

Nice work!

 

Lol, "with a 12 cm fan". Where is it mounted? (Picture, please! I imagine sitting oddly, all alone, there in the middle of the huuuuge radiator).

Very nice temps, by the way!

 

You need a 200mm fan or larger on a low speed, it will shift plenty of air on to that enormous radiator block

 

Very nice work!

Congratulations!

 

Thanks Waynio & GravitySmacked, yeah I'll have to start making them

Yeah lol:

Yeah I'm currently working through a few fan designs, I tried a 200mm fan in sketchup but it looked abit weird just slapped on the side of the heatsink. I'm currently trying to design a sort graphics card style fan that would blow air up from the bottom and the actual fans would be hidden.

I managed to get the lowest idle temp this comp has ever seen today, as my room is quite abit cooler than yesterday, without the fan too!:

 

verry cool build!!

btw you should try to get you hands on a big "Cross Flow Fan"
coolermaster used to make them for there stacker case.

they should do the trick and they are not to big.

 

I assume you are planning on having that alu anodized, correct? Bare alu is really going to be a corrosion nightmare.

The heatsink looks great. I keep checking in and am looking forward to seeing that sucker mounted on Blue Horizon.

 

Ah sweet thats perfect, thanks morbid_looney , I've found a website which does all sizes too:

http://www.airtekfs.co.uk/30mm-crossflow-fans.htm

Yep its gonna be anodized black to increase the rate of heat dissipation. Alu doesnt corrode though does it, unless it corrosion from reactions to different materials like copper? I though it just got a thicker oxide layer and make it a very dull colour?

 

Wow - great temperatures! What hardware and overclock etc is in the loop?

 

Its an Intel Q9550 @ 2.83Ghz (stock speed), with a Gigabyte radeon HD3850 overclocked to GPU = 705Mhz from 668Mhz.

 

Awesome watercooler scheme, and de heatsink is a nice way to cooling the liquid!

 

Aluminum does in fact rust, the enourmous advantage to aluminum over steel or iron is that aluminum only rusts 1 molecule deep. I'm not entirely sure what the concern would be, but even if you left it un-coated I seriously doubt you would have any issues.

Also, whats your logic on why anodizing it will increase the rate of heat transfer to the ambient? Unless the anodizing provides a lower thermal resistance than the bare aluminum you are going to decrease your rate of transfer, albeit the difference is bound to be quite small. Or did I totally miss something?

 

Yeah thats what I thought, because anodizing is basically artificially increasing the thickness of the oxide layer and the oxide layer is aluminium rust. I'm anodizing to make it black, and if you've ever stood in front of a black central heating radiator you can feel the heat coming off it alot more than white or silver ones.

 

Don't forget that anodizing will also crystallize the surface layer of alu. The sealed microstructure is a microscopic heatsink increasing surface area. This increases both radiant and convective heat dissipation. As you said the black colour is also a plus.

 

Nice , I didn't no that, thanks Javerh
