4850 waterblock

[spyderdixie]

what is a good water block for the 4850, I would need 2.
Also what would be the best way to hook a dd fillport up to a dd double bay res.?

Do you want a GPU only block or a full coverage block? You really only need the former for the 4850.

Can you screw in a barb to the fill hole of the reservoir, connect a tube to that barb, and then connect the fillport wherever you want?

a full converge block is easier to install and less hassle but will probably not work on your next generation card.
with a gpu only block you'll need to install small heatsinks to the ram and other chips but you have more chance that you'll be able to use it on your next generation card down the line and even if you don't I believe they're cheaper

what blocks will work? I will go with the block only and just use ramsinks.

Danger Den and Koolance both will have full coverage blocks within the month. They will provide better overall performance but won't be future proof as others have stated already.

I believe most people recommend the dtek fuzion found here: http://www.dtekcustoms.com/index.asp?PageAction=VIEWPROD&ProdID=222

talking about the same subject. can someone provide a picture of what a video card needs cooling besides the gpu and memory chips?

I know how the gpu has (or had) some voltage chip that gets very hot and maybe other chips. can someone provide a picture and how those chips looks like?

Swiftech's MCW60 is the old standyby. Dtek came out with a new GPU block that performs similarly to the MCW60. Here's a review: http://www.xtremesystems.org/FORUMS/showthread.php?t=157994

Looks like the dtek get a degree or two better GPU core temps, but it is very restrictive. If you have CPU and GPU in the same loop, you should probably get the MCW60. You could pick up a used MCW60 pretty cheap. I think it would be harder to get the dtek used since it is new to the market.

MCW60 have plastic barbs which gave me trouble on my last build. They flex too much. Dtek has metal barbs.

You will need to purchase ramsinks and voltagereg sinks seperately.

Remember that the sinks needs adequate airflow to cool the ram and voltage regulators. If you have a cramped case and can't add a fan to the GPU area, than a full coverage would be a better choice.
