Epic.
I think they had to reinforce res with kevlar and ask Super Mario to tighten connectors

Well, my mind is mostly made up then. 2x MCP35X + EK DDC Dual top + x2 HTS PMP400 heatsinks. Where did you get your MCP35X's? Can't seem to find a UK retailer that has them in stock.

Looks like they run at 26.8w max so I should be able to control them induvidually through my FC5 on a channel each.

Sounds like a plan if you're fine with modding the heatsink as I described earlier.

I wanted MCP35X initially but could find only 1 in stock so I got DDC 3.25 (specialtech.co.uk have loads) - which with a decent top like EK V2 is not much worse than MCP35X.
Obviously you loose PWM but if that's no problem for you - 3.25 is still great choice.

These DDC's though have power/ground through molex and RPM readout through 3pin so you'll need to move these cables into 3pin - not like it's big job though...

EDIT: I personally run them all the time full bore - thanks to the heatsink I'm not worried about the temps so have full flow all the time - they are quiet enough and just connected RPM readout to the Aquaero for information.

Looking at ordering a couple direct from swiftech.

One last thing; I'm assuming you're running the heatsinks passively, but could you confirm? I dont remember seeing any 80mm fans in your work log. That's one amazing drop from if you are.

The pumps will be positioned in between the intake fans on one side and the rad/exhaust fans on the other side of the front end of the bottom compartment, so there will be some decent airflow over them anyway.

Edit: Spelling.

Why would you spend money on PWM controlled pumps and then use voltage control with them.

Bear in mind losing warranty (seal) if you're going with Swiftech and dual top.
There are no seals in Laing so no problems with RMA if anything happens

I have plenty of direct active cooling on the heatsinks

I have 3x 120fans intake at the bottom, 1 for the PSU, 2 for the pumps - directly underneath them - also there's one in the front of the HDD cage which also gets a little bit of fresh air into the pumps area.
There's also plenty of space for the air circulation around the pumps.

Have a look at the bottom of my rig:

Nothing beats fans directly blowing at the heatsink but as long as you have some form of airflow getting warm air out you're fine - and definitely much better than with the stock pumps.

I went with two 655's, and I get mad flow rate, with very low noise.

I have this with dual 355 pumps and it works great. Bleeding is a bit of a pain but you get the choice of redundancy or 2 loops.

It all depends on your loop.
With very little restriction (like CPU only or high flow GPU loop) you'll be fine with 655's but with such restrictive loop as OP's 355 much better head pressure provides better flow than 655.
