Gut check before I start ordering...

post #1 of 3
Thread Starter 
First off, I'm completely new to watercooling - this is my first stab at it and I'm currently in the planning stages. This site, with all it's personalities has been a great resource, but I have a few lingering questions:

1. Will the MCP355 w/XSPC top be enough to drive a single loop with the following components? This is for my rig listed in my sig.

PUMP: MCP355 w/XSPC Top
CPU: EK Supreme HF
GPU1: EK-FC5870
GPU2: EK-FC5870
MOBO: EK-FB RE3
RAD: XSPC RX 360
RES: Swiftech Micro Reservoir

2. Also with low speed fans, say 800-1000rpm, am I going to be in a world of hurt and should I consider adding another 120 in the rear?

3. With the layout of my 700d, I plan the loop to be:
PUMP > GPU2 > GPU1 > CPU > MOBO > RAD > RES > PUMP
From what I have read, it almost doesnt matter what order as the temp will eventually normalize throughout the whole loop, right? Or do you have a better suggestion?

The paramount priority is keeping this rig as quiet as it stands in my current configuration.

Any help is greatly appreciated!

1. Yep, the 355 can handle a lot. It's a great pump, and for it's size, it can handle an amazing amount of restriction. A thing to look out for is how it gets. Make sure you put it somewhere where its bottom can breath.

2. I'd say get more powerful fans if you're planning on a heavy overclock. A fully loaded i7 alone gives off alot of wattage, along with 2 gpus and you're pushing it with one 360. Fans around 1500rpms would help your load temps, but another 360 would suffice I think if you wanna stick with 1000rpm. Push/pull + shrouds wouldn't hurt either.

3, Order doesn't matter as long as your pump is after your res, the same amount of heat will be dissipated regardless. I'd still suggest moving your cpu right after your rad. It's true that the coolest possible water is rad-out...and since CPUs are more fussy than GPUs when it comes to temperature and overclocking, let your GPUs run a bit hotter so your CPU can run a bit cooler.

Thanks for the input, quentin. I'll likely place the pump in the PSU bay, right near a pull fan and directly above a cool air inlet.

I currently have 3x Scythe S-flex 800rpm fans as exhaust on the roof, which is why I asked the question. I guess it doesn't hurt to throw a few more chips in for higher rpm fans. I simply fear the noise

Good to know that the order doesn't really matter although I will try to route the cpu after the rad. It acually might even look aesthetically better.
