Thanks, i just found it at Danger Den. Costly is an understatement, $74 for a small pump! damn. Dunno, ill prolly have to get it, this setup is getting quite costly :(.

I wonder what happened, i never messed with the freakin pump.

You may have gotten some water in the pump........... :shock: . It's not a sealed unit and the electronics are on the underside and can get wet fairly easy in the tight confines of the external housing.

Yeah thats prolly what happened. By underside you mean the actual bottom of the pump right? ( the one that is face up, since Corsair is running it upside down ). I wonder if i should flip it over when i get my RPL.

Also any ideas to sorta seal the unit? maybe wrap it around with electrical tape or something?

If the pump is totally intact, you can close off the base with clear fast drying epoxy. A while back a person modded the DDC pump, encased it in epoxy, shaped the epoxy and spray painted the pump a really cool metalic sky blue.
The picture was posted on http://www.systemcooling.com back then, but since has been gone. :(

I finally installed my new pump from Danger Den.

My problem is that now the system is LOUD, there is a high pitched sound coming from the unit ( funny part is, is less loud with the cover off than on ), looks like its the pump.

The high / low settings on fhe fan makes no difference, since the pump noise is louder than the fan.

Sounds like you still have some air in the loop. Those pumps "squeel" when they have air in them. They are designed for industrial use, so after all the air is out, you should add some padding to reduce any vibrations and damper the noise. The heat generated shouldn't effect it. I'm using one of those pumps and I still can't get over how powerful and quiet they are!

Hi All
Got mine at last from Moddersmart.Arrived quickly.
All fitted,just got to trim fan to fit the top back on.Have a Yate Loon 37CFM illuminated but it can't quite handle it.
Plan is to cool the 1900XTX with the Nautilus then get the processor under my D-Tek Fuzion and Iwaki MD15.Rad undecided as yet.

Yeah, i noticed the water lines are full of small air bubbles, ( it looks like when you pour Sprite in a glass ). Its really loud. You know of a way to get the air out quicker? maybe flipping the pump over?

Silly question

How did you get those d#@! clamps that Corsair used of the hose? Due to my own stupidity (see other thread I started) I am now basically having to retube the entire inside of the case :nut kick: . Not that bad of a thing (it WAS a learning experience) but when I did it for the couple that I did remove I ended up just prying on them with a pair of needle nose pliers until they were able to fit over the barbs. I am sure that wasn't good for the parts.

TIA for any information (and sorry if you posted that earlier but I didn't see it in the thread :sbd: )

If you're not worried about noise and you have the room, go for 38mm Deltas or Sunon fans with around 100 CFM or so. The 4c drop that you're now getting is pretty good IMHO, I never really cared for the Corsair aluminum rads at all.
guys how did you remove the stock nautilus 500 fan ? i see it's attached to the lid using threads with 6 star config thread head... i can't find any screwdriver to fit such a thread head even in my jewellers screw driver kit ???

Silly answer, with a dremel of course. :) Those clamps require a special clamping tool to mount with. The tool itself isn't cheap either. I've had to modify the clamp tool in the past to clamp down in tight spaces.

Those clamps are Oetiker clamps. They are popular in the industrial and medical fields for service. Depending on the tubing OD of the Nautilus 500, I would expect the size used was near the 14.5mm +/- 1mm OD near p/n 15400034.

Hello Everyone,

Well, I find myself in a similar situation as some of you have, I'm searching for the two G1/4" to 3/8" (at the barb) fittings and am having no luck. Since DangerDen isn't open on Saturdays, I'll have to call Monday, but the feeling of optimism has left the room.

If any of you can link me to the exact fittings I need, it would be much appreciated.

So far, the only deviation from the rest who modded the Nautilus, is that I have an Apogee GT for a water block.

Any help appreciated in tracking down this fitting.

Thank You

Anyone used a different block with this?

Post by uclajd »

Hi guys,

Thinking about getting a Nautilus500 for a friend's PC I am upgrading. Anyone try a different waterblock with this unit?

TIA.

EDIT: Just read the first page, sorry. I like the raddy mod though.
Noob? How many noobs you know with a dual-cascade? :D
