Corsair 900d with 5 radiators

Hello EOCers whats up? Well I am back to gaming after many years. I got a 900d for a stupid deal. Anyways I wanna run 5 radiators. Probably overkill, ha but thats what I do. Well my questions are fan layout. Do I use a push, pull or push/pull configuration? Also what about airflow? Would it be better to bring outside air into the case through radiators or draw the air out? All input from everyone would be appreciated.

The front and bottom of the case should draw air in. The top, and rear of the case should be exhaust.

With so much rad surface area, I don't think it will be necessary to use push/pull. Your water delta temperature would be good, and you might as well save a little money on fans.

Push it's typically preferred for single fan setups, but I would use the method that is easiest to mount the rad's and run lines as clean as possible.

In general, I prefer to have a little more intake than exhaust, and prefer to have the exhaust rads plumbed before the intake in the loop. This will make a minor difference in case temperature, but will be there nonetheless. In general, plumb the cleanest and shortest lines you can.

What radiators are you planning to use. Thinner radiators with low fpi will work better with push only, but will have more restriction. How much pumping power are you planning on having, and how many components are you cooling? What tubing are you going to use? Hardline tubing with larger radius bends typically have less restriction compared to elbow fittings. But it's a marginal difference. The larger benefit of hardline is less plasticizer leaching compared to flexible tubing. I mostly use flexible tubing for easier installation since my loops aren't show pieces, and I change the tubing periodically if I see any sign of leaching.

Many thanks for the guidance and tips. From my last attempted build I do have a brand new Swiftech 4x120 rad left over so I was just gonna purchase more of that brand. Unless you have a better suggestion. I also have a brand new D5T strong/810n pump and a new Switc h mcp655-b pump. I believe they are the same. Well just the cpu and a quad sli setup. I have so much 1/2" flexible tubing, its not even funny. So using the push configuration do I push hot air into the case?

Swiftech rad's aren't bad. I would just read some reviews and look at dimensions of different radiators to see what fits easiest without requiring modifications.

As far as airflow, front/bottom should be intake, top/rear exhaust. Push just means that the fan blows through the radiator, rather than sucking the air through.

Good info to research...

Some of the data may be a little old, but most of the radiators are exactly the same as they we're a few years ago, so the data is still relevant.

Many thanks EMU. I will check out the info

Additional Comment:

Ha ok got bit by the radiator bug. Gonna add another radiator. Bringing the amount to 6. Overkill? Current layout. In the front I have a 3x120 rad.Using 2 140mm fans as pushers and 3 120 as pullers (intake). On top I have a 4x120 rad in push/pull configuration(exhaust) Out back I have a 1x140 rad in push/pull(exhaust). On the window side I have a 4x120 in pull for now(intake). And on the other side I have a 2x120 push(exhaust) and an externally mounted 1x120pull(exhaust). But might just get another 4x120 and replace those 2. If I mount the lower rads externally I would be able to set up push/pull on those as well. Input and opinions are need and welcomed

Well I was almost finished with the build. But I decided to change all the Corsair AF fans(25-120mm and 2-140mm) out and switch them to Corsair SP fans. The 120s are SP120 31-002319(static pressure 4mm/H20). And the 140s are Noctua NF-A14 industrialPPC-3000 PWM. But now I was gonna change out the 120s to Delta AFB1212vhe-F00(static pressure 10.67mm/H20). Am I just getting paranoid about cooling or will I notice a difference in temps? And 5 rads are set up push/pull config. Only one is set up as push. All input and advice will be appreciated. Also how to I add my signature to my posts?

Post a couple of pics. I'd like to see it. For the record I prefer the Corsair High SP 120/140 fans because they are reasonably quiet and the noise doesn't really ramp up until after about 75-80% of max speed which you won't really need with all your surface area.

I avoid Deltas for two reasons, LOUD (may have changed but they used to be very, and I once had one slice my finger. Just my $.02.

So I ALWAYS used to swear to use a push/pull setup because it was clearly better. Well in my old age, I came to finally understand that it isn't. Most people also say that push is better, when it in fact, just isn't. Here's a nice video to give an overview....

My current build has my fans in a pull config. Temps are amazing and I couldn't be happier.

Hey guys whats up? Had a couple of water leaks during fill up. That Koolance 452x2 v 2.0 is a hard reservoir to fill and bleed. I managed to get it done. I do believe i still have some air bubbles to get rid of. So far running for 6 hours(water loops only) and no leaks. Running 2 Lamptron fan controllers to tame the Deltas.

That's a lot packed into that space. Looks a lot cleaner than mine would be.

Many thanks bro. I still have air bubbles in the reservoir. Flow seems good though. Water loops running for 12 hours now, no leaks. First time running hard lines. Not too bad i believe. Anyone know how to enable the signature option?
