New Water Cooling System

[joh06937]

i am no longer satisfied with my fan noise+heat performance of my cpu and my 2 hd 5770s. i am think of water cooling the cpu and both gpus with these:

i will be having a dual fan radiator with two fans pulling air through (i have heard that is better than pushing). i had a few questions though.
1) with an antec 902, will 1/2" tubing be too big? i have my hd 5770s right on top of each other.
2) will the temps get too high with that many components on one loop with a dual fan radiator?
3) will i need to get some ram heatsinks for the hd 5770s or does the block i chose cover those as well?

for the pump, i was sort of considering finding a water pump from something like an aquarium. would one of those work or should i just get a pc specific pump (maybe this one: http://www.newegg.com/Product/Product.aspx?Item=N82E16835108082)?

 

[just a noob]

Don't even bother at frozen cpu if you don't have to(shipping prices and prices in general are whack). Since there have been revisions to the 5770's you're going to have to check which one you need(involves taking off the coolers), and if you have xfx 5770's, I'm not sure who exactly makes a fullcover block for them.

As for a cpu block, if you pay $36 for it, you're going to get $36 dollar quality.

And the Antec 902 is a terrible case for watercooling, you can sacrifice all your front bays to mount a 120.3, or hang one off the back.

And having 2 gpu's and a cpu in the loop is going to put off a fairly large amount of heat. The best option would be to use a dual pass radiator(something like a gtx 360 would require loud fans) like the thermochill 120.3 or an xspc 120.3(again, quality will suffer)

And I would advise against using an aquarium pump(unless you use an aquacomputer based ehiem) If you do go ahead with this and want to avoid added expense(I know bomber is going to say mcp 355 blows away the d5 ) use a Laing D5(mcp 655) which has 1/2 fittings standard vs the mcp 355(Laing DDC3.2) which needs an aftermarket top to use(extra $25 usually).

You should also use a reservoir(easier to use than a t-line imo)

As for where to shop? SideWinder computers or Jab-Tech

Parts list(I'm just going to list the pump, radiator, and blocks needed):
Cpu: either the Ek supreme HF, or the Heatkiller 3.0
Gpu's: Core only block you will need copper ramsinks if you cannot get any fullcover blocks(if you do have a reference design, you can order direct from Ek Waterblocks)
Radiator: Thermochill pa120.3 or the XSPC 120.3 or a Mo-Ra 2 if you want to mount it on the side
Pump: either the mcp 655 or the mcp 355 with an aftermarket top I have had both, and I much prefer the 655 to the 355 simply because it lacks a high pitched wine

If you couldn't already tell, this isn't cheap, I would just look into aftermarket air coolers instead

lol, i realize it isn't cheap
i was hoping to just use a heatercore from a car for the radiator (budget and i could use a more complicated project ). i'll end up mounting it all above my top fan most likely.

hmm, i saw some reviews for the cpu block i linked and it performed pretty well... about 1-3 C above the hk 3.0.

for the gpu, i wasn't really sure what to do (i am [strike]pretty[/strike] completely new at this). i figured a 5770 specific block would be best. i have also heard some others having trouble getting blocks on their gpus... my board is the reference one (two crossfire bridges and looks exactly the same as the xfx i got before the custom pcbs started coming out). would i get the same performance with some different gpu block as i would with the 5770 one i linked?

i am just going to try and make my own reservoir out of clear pvc pipe.
