View Full Version : Watercooling graphics card

I noticed many watercooling kits don't come with a GPU block that covers the RAM. Is it not neccessary to cool the RAM too?

It depends on the card. The 7900GT didn't however most other cards especially the GTX's 7900GTX, 8800GTX will require at least a passive heatsink.

How about an x19** ?

Well GDDR3 RAM doesn't get that hot AFAIK. Still the stock cooler covers the RAM so I'd go with at least so passive RAM sinks just to be safe. Zalman waterblocks come with RAM sinks and you can even get a Waterblock for the RAM if you really want to get fancy.

How about an x19** ?I'm water cooling my x1900xt, and the ram runs MUCH cooler naked than it did with the stock cooling. The stock "cooler" takes heat from the gpu and puts it on the memory, which doesn't "cool" the memory at all.

Serious. In that case all you'd need is a waterblock that cools the GPU and you're set. Wondoer how hot the 8800GTX memory runs.

hazindu how can you meaure the temps of the RAM?

I've often wondered whether a full coverage "monolithic" waterblock does more harm than good as far as cooling the memory goes. Swiftech does make a ram waterblock, completely detached from the core block. Has anyone tried this solution?
