Water-newb!

post #1 of 5
Thread Starter 
Hi guys

Am considering selling my new Phantom 570 plus my Gigabyte 460 for £400+ and buying 2 480's for sli - some great prices for 480's at the moment. Which would only seems to make sense if i could put them under water - i hate excessive noise.
Also going to be getting 2600k/P67/1000wPSU upgrade too - and modding my H50 for CPU cooling

The thing that makes it difficult is that i'm using a P180 Mini which is a small case, only capable of holding a 240 rad after modding.

Would a 240 rad with 4 fans in push/pull be enough to cool 2 480's??? Bot looking for exceptional temps. Idle @ around 35c and loading @ around 60/65c, for example, would be considered acceptable - just about, low noise is the priority.

Am considering using EK-480 Blocks + Resvoir/Pump combo - trying to keep it as simple as possible.

Currently just brain-storming so there is no rush, but would like to think i could put together a nice enough dual-gpu water-cooled rig without having to sell my case and go regular atx.

TIA

A top notch 240 rad could get you in that temp range. Why not mount a bigger rad externally. By the time you put all those fans on the rad, you will be as loud as the aftermarket air coolers you could get for the 480s. If you put an RX360 or an RX480 outside the case, you could use low speed fans and keep your temps lower than your threshold mentioned above.

In my experience difference in idle/load temps isn't that great, personally I go from 35-40 idle to 40-45 load.

That's a 360 rad on push pull fans, but low quality fans...

That's also on a single 480 though as well, with a decent pump and blocks put in parallel you'll prob get a slight rise in temps, but if it's any consolation, the temperature is more defined by ambient, I don't believe this rad struggles to dump the heat at all.


Going for a 240 Rad, I would definitely use powerful fans.

For a cpu and sli 480's a 240 with high rpm fans would just get you by depending on how much o.c you are looking to do. A 360 push/pull would give you optimal temps though. You can mount it on the back or side of the case if you want so you don't have to mod the case or look at upgrading the case in the near future while leaving the rad off to the side.

Not looking for major overclock - maybe upto 800mhz per 480.
I mean the onmi-alc would give me the temps i'm looking for and that uses a 120mm rad, so i think it's possible.

Now if i was to attempt it - should i go for pump/resevior combo + rad, or, rad/resevior combo + pump, or is it better to use rad + pump + resevior (all seprate)???

Mounting the rad externally never crossed my mind - will look into it but keeping everything internal would be preferable.
