More Watercooling questions

So, I made a thread a while back on watercooling. I was thinking of going with a Level 10 GT case, which is indeed, horrible for WC. So, I decided to go with the Corsair 800D instead.

I'll be cooling a 990x i7, 2x GTX590s (Will definitely be OCing the CPU, and I'll try and see how far can I OC the 590s as well) + RIII Motherboard & 6 Dominator GT Modules (Mobo and Ram blocks are more for looks than actual performance, but I still need to figure out how to fit them into the loop).


1 - Radiators

As for the rads, I've selected these, but if you think there are better options, I'd be glad to hear you out.

Top Rad (360mm) - XSPC RX360
Bottom & Rear Rads (140mm ?) - Black Ice SR1 140

Now, I know that 140mm fans can be installed on the bottom & rear, but I'm not sure is 140mm rads fit. If I have to go for 120 instead of 140, I'd choose the XSPC RX120-D

If someone could tell me if I can fit 140mm rads, and what rads to choose, it'd be awesome.


2- Fans & Fan Controller

So, with these rads, which fans will deliver the best performance? Also, would installing fans on both sides of the rads do any good?

I don't mind the noise while I'm gaming, but I intend to have a fan controller to slow them down when I'm not. I've been looking at several controllers, but I haven't found a perfect fit. I'd need it to be able to handle at least 3 fans per channel (4-6 channels would be nice), and it has to look good in the 800D :D


3- Pump

I've been taking a look at these three pups' specs and reviews, and I haven't decided on one yet.

- Swiftech MCP355
- Swiftech MCP35X
- Swiftech MCP655

Which one of these three pumps will offer better better performance? Also, which top should I buy for it?


Thanks a lot!
 
My next upgaarde to my loop will be the pump and l will be getting the MCP35X has good reviews, G1/4 instead of Barbs, + the pump can either be controled by PWM or manual.

BI SR 140 has M4 threads, G1/4 thread for fittings, 140mm fans fit ok so you should have no problens fitting it, using the the BI GT Stealth 140 Triple.

If you are seriously looking to watercool a 990x, 2x590's and mobo you are going to need more than a 360+140 imo as you will be throwing about 1100w+ into the loop. Looking at the high fpi hwlabs gtx radiator and data from skinnee

Here is the same data for the rx360

If you are ok with water/air deltas in the 15 degrees range you will need fans at 2500rpm+, which will be incredible loud. I would seriously look at using 2x360 rads in or a 480+240 like many do in the bottom of the TJ07 case as i think your going to be on the absolute max a 360+2x140 can take.

Watercooling mobos is costly, dumps a lot of heat into your loop and for very little overclocking benifit. Unless you really want the look its not really worth it.

I don't think you'd get a 140mm rad in the bottom of an 800D as it may be a tad too wide. A 2x120mm (240) rad will fit in the bottom section once the lower cage has been removed so be prepared to get the Dremel as you'll have to mod the case.

The Lamptron FC2 is a simple and understated yet powerful fan controller with 45w per channel on 6 fan headers.

As you are probably looking at running separate loops for all that hardware you'll need more than one pump. I would always go for the MCP655 a.k.a. the Laing D5 Vario, but the other two you mention are also fine. You may be better off housing the pumps in the optical bays, therefore this may also influence your choice of reservoir.

As JeffyB mentioned watercooling the motherboard adds clutter and heat to your loop for little benefit.

I've seen expert modders put a 360 rad in the bottom of an 800D and a 480 rad in the roof. Only you know if you have the skills and patience to get the job done. Personally I think 2x360 rads is the minimum requirement for all that you're trying to cool.

Judging by your spec you have money to burn, so the TJ11 may be a better option than the 800D. It can house a 480 and a 360 with ease I believe.
 
Or get a Mountain Mods case and put in as many rads as you want!

I'm going to assume you really do intend to spend that much money on a computer and that you can therefore afford the very high cost of water-cooling all that. So, I would do two loops, one for the cpu/mobo and one for the gpus. You will need at least two 360s and two pumps. By separating the loops you can get whatever pumps you like and you won't need to get a D5 (MCP655) unless you really want to. With one loop, the D5 is the minimum you would need for that lot.
