I have posted a few times in the last few days.

Still a touch undecided about doing this but if I can get a good system for ok money then I may well pull the trigger.

Remember its to replace a H80 thats been messing about.

I am looking at adding in one of GTX 580's as it gets very hot in the 650d case, when they are both running hard with a decent oc
The other (bottom) never gets above 65c even under a big oc so there is no need to water cool it.

I am after a double rad based system and need it to cool my oc 2600k as well

I have looked at this kit and it seems ok + a few extra bits to make it up.
I am not necessarily after class leadin performance - more to get me going and to perform as well as the H80 which is pretty good!

My basket - what else do I need?? More tubing / connectors?

What tubing can i buy to go with this water kit?

I am not sure the diameter but looking at the reviews people say the included tubing is pants
 
I have just been trying to measure - I dont think it wil fit anyways - with one row of fans on it will be bloody tight on my mobo top heatsink.

This is hard work trying to sort this out
 
My Basket - about £300 and bloody expensive if its not going to cool well therefore not worth it

buy a new case then you are looking at £500 what is the point - its starts getting crazy
I paid £165 for this case 3 months ago

surely a decent 240 rad with a couple of fans and £200+ spent on the rest of the bits will be better than a H80 and the air cooler on my msi 580

otherwise how do they evey sell any - and I am sure they sell loads ?

There is more suface area on a 240 rad than a gpu and 120 rad surely.
Plus the ambient air outside my case is a lot cooler than the air inside my case when 2 580s are going and the H80 is pumping in as well
 
I didn't ever plan to watercool ,I am looking at it as a result of having a faulty h80.
I am reluctant to use another one, but see little alternative - my temps with it are actually good max 75c with 1.45v on prime.
With an offset oc my general load temps dont go above 50c approx. I dont want to buy something else and get worse temps, what would be the point of that.

My top gtx 580 does get hot in my 650d in real demanding games such as crysis 1 & 2 fully maxed or benchs etc. This is because the coolers on both 580s output a lot of their heat into the middle of my case - a lot of their heat distribution comes out of the back of the cards, rather than out the back of the case.
The 650d has no cool in airflow at it's back or middle therefore my top card gets starved of cool air as the case cool air intake(200mm front intake over hds) meets the cards hot air output if that makes sense in the middle-ish of the case.
That heat rises and is vented out the top by the 200mm

I have tested - by taking the side of the case off and my top gpu temps drop 10+ degrees at 100% load.
That is my target for the gpu and allows me to overclock more:) This will be more important in the future when games become more demanding or I buy a 120htz monitor.

I therefore was looking at using water to cool my top gpu and CPU to make spending another few hundred pounds worth it - I was hoping to get equal cpu cooling to the H80 - I will be happy with that but also cool my top 580 at the same time.
My top gtx would then not be using any case air to cool, and using my loop.

My target temps are 75c max 1.45v 100% load CPU
And 80c top gpu with a decent amount of volts and overclock.
I presumed to get better temps than that, but you are all say no?? if thats the case I might as well keep my money / the H80 and get the side mesh panel and maybe a 180mm fan.
I dont really want to do that as its ugly + watercooling is new and exciting, however I am not prepared to buy anything else new i.e. case or anything just to watercool. (Obviously will happily buy the bits for watercooling)

I was thinking about that - however you dont then have any case exhausts - so the internal hot air will be trapped.

someone suggested putting a 200mm rad in the bottom instead of the intake fan - that seems a better option then have the 120mm exhaust doing just that?
 
True but one of my 580s will still be dumping hot air in and they pump out a lot into the case - just a concern

having never done it its hard to know for sure??

Take the easier option mate, and get the mesh side insert for the 650D side panel. Stick a couple of fans (intake or outtake) on them and that'll sort out your GPU's.

The 650D really only takes watercooling for CPU or GPU - not both due to lack of rad space.

And also be careful which Radiator you get for the top. 240's, make sure they aren't too thick otherwise your fans or rad will touch your motherboard, and be careful with a 280 as the case doesn't leave much space for manouver at the top due to the top sata hdd plastic (stick your hand in to the top and you'll know what I mean).

been doing my research too as this H100 isn't exactly great - keeps me in check at 4.6 but I'd like to go back to 4.8 at some point by custom watercooling JUST the cpu for now.

Keep us posted though which ever route you take - me gots my eye on this thread ;)

My H80 is good for 4.8 mate with an offset so its not cooking all the time.
With Prime it hits 1.432v but its fluctating constantly - I think because I have some power saving settings on in bios - either way is stable - no BSOD's

I was testing today with the 650D clear side panel taken out and the heat these gpus put into the box is crazy - the HD cage gets hot but in AIDA my HD temps are about 35c which isnt too bad considering.

I was thinking at least if I wc one of them that will reduce the heat in the case a hell of a lot and it may make the 3 rad exhausting possible (120 and 240 as mentioned)

The other thing I notice is that even though the cards are pumping out loads of heat the top of the case didnt feel partcularly warm - that might have been because I had the side window out and the heat could escape.

I would hate to spend £300 and then be back at square one and not be able to oc gpu!!

I did fint this earlier - which got me thinking and looks bloody good

@@EllisDJ - You tried moving the second HDD cage out of the way of the front fan? that might help things. I also note that the front fan isn't one of the best - I believe theres a coolermaster 200mm one thats much better allot of users have been flocking to.

I doubt very much you'll be able to hit the same oc on CPU and an oc on the GPU with watercooling. I also don't like the idea of the one major intake fan (front 200mm) pulling hot air through the rad and into the case - thats not going to help cool the other rad at the top....

Hello Mate

I have tried with the HD cages in all 3 ways - it makes no difference to my gpu temps.

I have tried with the hd cage on its own in the middle of the case - I have tried and am currently using it with it on the bottom only of the 2 as standard (hope that makes sense) and I have tried with both cages in and the bottom cage empty and the HD's in the top - it seriously makes no difference.

I have tried with a fan blowing straight between the middle of my 2 GPUs I have also tried with a fan blowing up towards the exhaust and blowing at the back of the gpu's - still no difference.

The only thing that makes any difference is taking the side of the case off and my temps drop.

I think because Max Heat ---->> from GPUs and only the outer edge of 200mm going <--- back up the case along the windowd panel

On Heaven with an OC of about 1133 volts - 900 and 2100 roughly I am hitting high 90's at the minute - with the side off its 90c.

Thats hot - if you look at the deisgn of both my cards - they are dual fan big heat sink designs - I think the big asus cooler which is immense -top temp of 65c with a big OC strangle / chokes the air from the MSI on top and is feeding the MSI Hot air. Ther is a 30c difference in temps betwen my 2 cards.

I was therefore looking at the mesh side panel and maybe a 180mm fan intake - however at best I would get the same temp as with the side off.

I thought better - WC it and the CPU - now I have learnt a lot I feel about it, and how maybe I cannot do it, they way I want or on a sensible budget.

Its like any project - you start off wanting to spend £150-200, you end up with a basket 50-100% x more

Is this enough Rads for a 580 and 2600k OC? - http://www.overclock.net/t/969234/close-combat-a-corsair-650d-water-cooled-build/100

Apologies if I appeared to shun this idea earlier in the thread - I am still not 100% on that design - because
1. What cools the HD's?
2. There is no exhaust for the heat from my 2nd GTX 580
3. Overall cost

both oc and the 2600k oc ??

I thought the bottom 200mm fan was intake?

Looked again is exhaust - my hd's get cooked by my gpus at the minute and they dont heat up so would probs be fine anyways

It seems bold from what everyone else has said in this thread - however its interesting none the less.

The guys sig is a big OC system - but not the system mentioned i.e. 6950s
