You have fitted 6 fans right ?

The barbs are 90° or straight as i can't see them in the photos

thanks

The fans are exhausting out of the case, and 6 fans fit like a glove.

I used straight barbs located in the upper front 5 1/4 bays, but keep in mind that the tubes in that configuration interfere with the top 3 bays in order to prevent kinking.

Feel free to drop in any other questions you may have. I'm in the middle of a move but I'll try to get an answer back to you soonest. The only price on answers is that you promise to post some pics of your rig once it's done... :)

Looking forward to seeing you on the boards.

Using this thread for fixing ideas, here is my 1rst water cooling set-up, My case is the original Cosmos 1000 case that came out before the 'S' version

As there are too many photos here are just some of then the rest can be seen on my blog
Lets go watercooling Minty95’s Weblog

Looks great! Fine job of modding for the third fan.

Wish I still had one of these kicking around for testing purposes, I'm curious if 20mm (vice standard 25mm) fans would allow for a full internal 6 fan push/pull config.

Update, 4th fan fitted, wiring we tidied up, checked Artic ceramique, all Ok still only idling at about 33 / 35°

Missed this post during my move.... :)

Looks great!!! I had a quick look at your blog while I was at it. :)

My loop is finally going through rev. 2. I've got a new Apogee GTZ, and I've had the case long enough now to start drilling holes in it. :)

Going to mount the pump on the back wall, as well as see if I can come up with an internal install for the PA120. I ordered some Scythe fans to pump up the airflow, but only noticed after they arrived that they are 38mm models which won't fit up top so fan replacement is going to be put on hold for now.

Noctua Nf-p12 time and gonna enjoy seeing this hopin the GTZ goes on sale in the forum again so i can grab mine more mods i say more mods.

Looks like the PA only needed a minor mod to the case side to fit.... :)

Here's the problem......

This is the only orientation of the rad which would work using the lower fan grill. The bleed port screw on the rad extends too far out and prevents the case side from closing.

Here's the lower bar on the case side which is hitting against the screw.

Et Voila!!!!! All it takes is a bit of dremmel work and we now have a hole allowing the screw enough clearance to allow installation of the rad on the bottom mount. :)

All that's left now is to decide the airflow. My initial thinking is that having the Scythes drawing in from the bottom (blowing upwards) will prevent airflow from getting through to the rear of the case across motherboard components so I'm leaning towards blowing down.

Any thoughts on that?

How often do we hear folks asking about where to get extra Coolermaster HDD racks for their front mount fans? Most folks could care less about the extra HDD storage space, but want an easy way to mount the fans.

Here's a poor man's mod for an extra fan......

Couple of L Brackets pop riveted to the top of the HDD mount. (I made these brackets myself, but it's probably easier to just pick some up at the hardware store.... :) )

Mount the fan to the brackets....

Installs like a charm, and the shock absorbtion mounts for the HDD rack should keep any fan vibration away from the case. It also allows room for the tubing from my forward facing barbs which wouldn't be the case if I had a second HDD rack.

I've got a 3.5 fan controller in the second slot, but if a person only had an optical drive they could probably mount a third fan to the bottom of the rack in exactly the same manner.

Nice :), for info I remplaced the fans with Noctua Nf-p12, 3 on top of the rad and took the 4th of, am running at 44° idle OCed at 3.2ghz and 55° running prime for over 2 hours

Res installation:

Along with mounting the pump to the back wall I've decided to place the res directly behind the top two 5 1/4 bay covers. That way it's out of airflow, and I can easily monitor levels by popping off the cover(s). Downside is that in order to clear the top/front lip I had to install the mount almost tight against the barbs of the top rad making securing the res almost impossible, and filling the loop will require removal of the mount.

As you can see, it's an extremely tight fit in there. Initially I had the screw coming in from the outside as I had to have access to the screwhead to tighten. (The nut has a built-in lockwasher so I didn't need to hold it with a wrench).

My solution was to come in from the other side, and use a locknut to both secure the screw, as well as provide a stand-off for easier access / installation. Had to go out and purchase a proper set of wire cutters for the bolt/screw cutting feature in order to get the length just right.

I've now got easy access for filling the loop.
