Liquid Cooled Corsair Air 740 build "Spectrum"

post #1 of 33
Thread Starter 
Hello all I purchased all the parts for this rig on black Friday and got some sweet deals! I ran into some snags along the way and learned so much while working through them. This is my favorite build I ever put together. I could use some help finding a name so suggestions are welcome as well as asking for some opinions along the way. I'll break up my posts according to the events that took place and where I would need to stop and wait to work on it again.

Alright so all the parts came in and I was beyond excited and was ready to start building.

I began building and everything seemed to be going very smoothly. The CPU and RAM went in easily as well as the board inside of the case.

I also installed all of my Corsair fans
- 3 x 120AF performance in the front
- 2 x 140AF quite on bottom
- 1 x 140AF quite in rear

Now this is where things begin to go south. I had originally ordered the EKWB predator 280 because I was told it would fit... Well it didn't, at least not the way I wanted it configured. I could have gone with only two 140 fans in the front and it could hav worked, but I decided not to. I wanted to stick to my original plan as much as possible. On top of that there were a few scratches on the copper part of the block and only two of the locking nuts that screw onto the CPU posts. I RMA'd it and purchased a 240. At this point I was stuck for the time being.

When I had to order the Predator 240 because the 280 didn't fit I also decided to buy some black soft tube fittings as well as clear tubing and a 150 reservoir all from EKWB. I also purchased some lime green clear coolant and another QDC and I'll explain why later.

Now right before my new Predator 240 arrived my case led strip kit came in the mail so I was able to install that. I purchased two more strips for a total of four but if I want to use them I might need to solder them together for there is no easy connection at the end of the strips that came with the kit.

Once that was installed the 240 had finally arrived the following day. This is what the build looked like with it installed

Looked a little boring so I was very excited for the tubing and everything to come in so I could make it more convenient to fill and aesthetically pleasing.

The clear tubing, fittings and res arrived a few days later and I was very excited to start making my first custom loop ever. I game planned how I wanted my loop to be built and tried planning further as to what it will look like of I add a 360 rad and a GPU block. Once I was happy with the plan I started working on it. Installing all the fittings and cutting all the tubing was pretty easy. Everything seemed to be going well until I got to the acrylic CPU water block mad.gif !!

Well I was very gentle with the block because I heard horror stories of them being very fragile and will get stress fractures if the fitting is tightened to much or threaded improply. Well I took my time went very slow hand tightened it as far as I could then tightened it just another 1/4 of a turn and CRACK!!!!! mad.gif :thumbdown:

Well that's not going to work now is it so I was done with acrylic period! I went online and ordered the EKWB EV-Supremacy EVO Acetal+Nickel CPU Block.

Once that finally game in I stalled the proper plates internally and made sure the loop was going into the proper intake/output on the block and went from there. Here is a picture of it being leak tested

As you can see I upgraded the ATX 24 pin and GPU power cables with white 550 cord. I did all the sleeving by myself for this build. I will also discuss later how I made my own 2 way and 3 way case fan splitters. Also the green is a little lame in that picture and you can't really tell it's green if it wasn't for the res. I couldn't have that so I ordered some Mayhem Green Pastel concentrate. I also wanted to future proof my loop some more so I ordered a Swiftech MCP35x for only $60 as well as a Bitspower Heatsink for it. The plan was to replace the 6W pump on the Predator with the 12W Swiftech pump. Due to similar dimensions it would work just fine.

Alright so this should be the last update until I purchase more for my loop or PC.

The pump, heatsink and concentrate arrive just in time because I was getting surgery on my collarbone two days later! I originally was going to uninstall the 6W DDC 3.2 pump from the Predator and install the 18W Swiftech DDC 3.2. Well after a little debate I decided due to the location of the pump in might overheat at max loads, which for now will never hit till I upgrade the loop. The heatsink would have helped but it still would have been above the res making it more difficult to maintain, bleed, and fill. With that being decided I placed it in the back on the bottom. Now because the heatsink was made for large DDC 3.2 Block tops the screws were too long. Well easy enough fix so I went into my garage pulled out my Dremel and cut them down to the size I needed them. I put it all back together and started the new loop.

I'll monitor the temps of the pump to ensure the load isn't too much and if I need to I'll add a 80mm fan back there to keep it cool.

Once the pump was all put together I decided on a few changes to my loop diagram and started going to town. Now due to the pump needing to be plugged into the CPU_FAN header I had to Y split the two CPU fans and installed them into a CHASIS_FAN header. I have four fan headers on my board which works perfectly. One for the front, one for the bottom, one for the top and one for the rear. At 1Amp max load per header that's plenty for a max of three 120s at .13. I custom built a 3 way splitter and 2 way splitter for the three front AF120 performance fans and the two AF140 quite fans.

I leak tested the loop for 12 hours and this is the final product!

Also quick question guys should I paint my grill inserts on the Corsair 740 white? I want something neutral that way if I change the loop liquid color it will still match?

Are you going to block your GPU as well?
