Homemade water cooling Case (DIY Fan Controller)

[rakesh_sharma23]

Now on to my DIY SUB
Currently i modded my Sound blaster Audigy Value 7.1. Installed new Op-amps Burr-Brown OPA277 and Capicitor mod.
It improved sound quality a lot...But now i think i Should have new SUBWOOFER..

So here i am with my own Power Sub-woofer.
DIM:-
14inc X 14inc X 18inc Sealded Encloser made from 1/2 inc thick MFD board.
12inc - 4ohms - 800Watts Sub- drive
home-made 450watts amp.

WOW, just WOW.

does OMFG mean anything to you.

Do you have the plan for your amp? did you just come up with it or is it a design from a book.

 

[rakesh_sharma23]

Thanks Nuke
Well i studied online about Sub-woofers and made my own box.
And for poweramp, originally i found it on a Turkies Site, i redisgned the amp with some part change like driver transistor and few pf change..Amp is having 8 Darlington Transistor in Power stage.
Darlington Transistor are it self a pair of Transistors in a singel pack. So in real it is having 16 Transistor... Very power full

[blackpanther26]

Wow!!! I can't say anthing else. It looks like you worked hard on this project. How long did it take you so far from the first step if you can estimate.

 

[rakesh_sharma23]

Around Dec 2007 i first decided to throwaway my old metal pc cabinet and buy a transparent case.
But when looking on rate of transparent cabinet in India ...It was too high.. Then i though why should't i make my own case.

Since then my rig modding is continue..... Adding new mods ...


Thanks Mr. Blackpanther26

[Conumdrum]

Glad I can just buy stuff and make it work, but very well done! One reason so many peeps like him come to the USA with UBER engineering skills. Smart guys get all the big bucks.

thanks Conumdrum

 

[rakesh_sharma23]

I have made the waterblock for my HD4850 GFX Card.
Have a look. 100% passed leak test.

Will test it on sunday... Hope to give you performance report soon.

 

[Shadow703793]

^Is that Aluminum (the fins)???? If so you are going to get corrosion! Copper + Aluminum + Water = Bad. Full Aluminum + Water is ok.

 

[Conumdrum]

With his uber skills and constant playing, he'll see any issues way before any occur. The OP knows by now the mixed metals issue for sure.

Neato GPU cooler!

 

[Shadow703793]

^Hopefully other wise you can run in to problems down the road.

 

[rakesh_sharma23]

Thanks for your reply...........
I have done all Galvanic Corrosion calculations according to cathodic area , metal conductivity and metal thickness for Copper and Aluminium with Anti-corrosion water coolent ... it results to about more then 30 years for this block.....So NO worry...

Stock cooler is removed from HD 4850 , tonight hope to fit this block and run some tests....

Posting results soon....
Thanks ones again
