Upgrade Bug!!!!

I will do but I have one which is working, so may get the loop done before the CPU is changed - it depends how quickly I can get the ££ for the whole lot in one go - should be easy enough to swap the CPU once the loop is in right?

Yea its easy, just unscrew the block and screw it back on when you installed the CPU. The water wont spill unless you take any tubes off haha
 
There's fine and there's good.

360/240 with decent airflow is what you really want. I ran that in a modded 500R and they definitely ran hotter than the pair of 7970's that preceded them.
Ideally, you also don't want them cooped up in a small case with one rad effectively feeding hot air into the other.

He could do what i did and get a Phobya 1080. Its essentially 3x 360 rads and it has amazing value!

He's gonna have to make it external but in return its easy to clean, more room in case and always has access to fresh air.
 
it won't be "great", but it's definitely more than sufficient

(im running 2x7990 + 3770k on 2x240 rads and can say that it's absolutely fine)
 
Many dont like the idea of external, but i like it. And i think he would too, a lot easier to work with.

Overkill for 3 cards? Then what am i doing :D?

Agreed. I think they're pretty sweet and keep things simple.
Can understand why some people aren't keen on it though.

In his case, i think something like a Corsair 540 would be fine.

No, overkill for two cards. But then it depends whether he wants to run big OC's for 24/7 use/benching like you do.

Tamzzy, I don't know how the hell you get away with that tbh. It certainly wasn't my experience when running a couple of 7990's :D

External wouldn't work, I don't have the space and it makes porting it around difficult! The reason I have the S2 is due to space, I have no room for an ATX case and to be honest, don't want one!
 
2x240 would be fine if you're not running much more than stock clocks tbh.

Personally, I'm the type that wants to see not much more than 45°C with watercooling. If you're happy to have them running at temps equivalent to decent air, then sure.

The CPU will be overclocked for sure but the single 290 I have running 1440p is perfect - just don't see the point in going under water if not to get dual cards, seems like a waste!

It's not a waste, but yes, it is more useful and justifiable when running more than one card unless you're big on OC/benching.

Yes Ranger, I know... :D Still, not everyone needs to OC for day to day stuff.
 
My CPU doesn't hit anything over 62c (h100i) and GPU is 78c (reference cooler) - so running 2 under water with an overclock shouldn't be too bad right?

Well no, but if you want the advantage in overclocking from water cooling other than it being quieter then id get more rads!

my rig crunches seti@home on all cpu and gpu cores. temps at the moment:

gpu @ stock clocks and volts: 51c on all 4 cores
cpu 4.2ghz @ 1.13v: 63-66c (not delided)
coolant: 41.3c
ddc pumps are rated to 60c, so coolant temp is well within spec

it's not "great" temps but it's sure as hell over 9000x quieter than air cooling
 
I ran sli 780 lightnings and a 3770k for ages with 2 60mm thick 240mm rads and benched/pushed em hard and temps were still great.
Now I've added a third 240x60 and I'm tempted to add a third 780 if one comes up at the right price :)
