Hello, fellow liquid cooling enthusiasts!

Iam in great need of your advice. Would it be possible to watercool GTX 460 cards in 2-Way SLI with a singel rad (Push/Pull) with decent results?

Thanks in advance :)

single 120 rad and 2 gpus?
possible yes, useful no

what about cpu?
i would recommend at least a 240 for 2 gpus, if not a 360

The reason why i consider it is to reduce noise, my Sparkle cards sounds like an airplane takeing off. I have a 360 rad for my CPU already. Thanks for your post!

well this should work then, do a single loop and the graphics cards to and add the 120 rad as well (maybe a 240 rad if you can fit it) and run the cpu and GPUs on the same loop

+1 ^
single loop is more efficient :)

Ill do that then, make 1 loop. Thanks for the help you two!

If you intend on overclocking the 460s to atleast 1k core go for a 240 rad.. mcr 220 is cheap!

if u are going sli with 1 fan of rad u should use gpu only blocks then sinks to cool the pwn and memory, but the sparkle cards i think are nonreference so u may have no choice

I dont think stock cooling could match the capacity of a single 120x1 radiator with a good fan even on SLI.

As the delta from ambient to coolant gets larger, the radiator also gets more efficient.
Its not a true liner line which we see. Its more of a archway upwards.

The higher the delta the greater the efficiency on any rad.

Now the acceptable value we pick on the cpu is a 7C delta from coolant to ambient.
That means if your ambients are 20C, your coolant shouldnt be higher then 27C when your entire computer is lite up.

On gpu's thats completely different, because of the nature of gpu's.
There not as heat sensitive as cpu's, so even holding a 15C delta to ambient on gpu's would still be considered a win.

20C ambients.. coolant 35C... would mean you'd still keep loaded temps below stock air cooling.
