Watercooled BGA - Is it worth it?

[stocky]

Just been wondering how much adding a waterblock to the memory on a GPU helps with the memory overclock?

Is it better than fitting OCZ Copper sinks with a fan, or about the same?

Just been thinking that the temp from the core must spread over the metal plane to the memory, where as with the normal OCZ heatsinks they are all separated...

Theres been tests done and it seems that once RAM hits a certain point, no amount of cooling or voltage will let it go further. Normally this speed can be hit with heatspreaders/ RAM sinks with some airflow.

Thing is though... all in one blocks are easier to insulate if you`re gonna use a waterchiller

I`d say for practical uses, get a waterblock for the core- more likely to be useable with future cards and RAMsinks but the price difference between that and an all-in-one is only about a tenner

Yeh, that's true for normal RAM - just wondering if the same applied for BGA memory on GPU's.

Does Mav use these full card coolers to get his memory overclocks?

Yes he does!! and 2.4v on them (2.1v standard).

Thing is that they look nice as well as reduce the need for regular clocking (not uber bennchie clocks) to use extra fans too.

I also use MOSFET water cooling on the cards too

The larger coolers are not best suited to chilled action - the large surface area exposed presents it's own problems.

Mosfet cooling aswell ey, hmmm... Which ones - to replace the big sink near the rear of the card?

I would always add ramsinks and probably reseat the power regulation heatsinks for better contact, but once you have done that watercooling is unlikely to gain you anything, even using vmods. IMO full card coolers increase restriction, increase the heat in the loop and restrict your upgrade path. They do look pretty neat though.
