Corsair Obsidian 800 D Watercooled

[Chaltharr]

hello all. I just got the Obsidian 800d and plan to watercool it. I have made a picture sketching out what i want to put in it and where to put it. I was hoping for some feedback on the location of things.

I have bought most of the things to put in (list follows):

The fan in the front bay will need to be able to draw in air from the outside or it will not work, with the rad fans pushing air out of the case you will not need this anyways. The HDD fan is 140mm aswell. Dont put the pump down there or you will block the very little air that makes it inside.

Just a quick blurt while I drink my tea

 

[Chaltharr]

i was thinking it did not need to draw from the outside just give the air coming up a bit of a push toward the back just above the graphics card? Or should i just reverse the fan in the back and add a filter?

Any suggestions to alternate placement of pump? looks wise i was pretty much set for the place i had it.

 

[AMDFTW]

awsome choice on fans IMO cant beat noctua

 

[Chaltharr]

I was wondering... Will this setup handle chipset and mosfet blocks aswell or will i then have to go for a separate loop for that?

 

[biscuitboy]

Yeah, should handle it fine mate I think, stick fans in Push pull to further reduce temps a bit... A Res-top for that Laing would tidy things up, free up drive bays and reduce tubing a bit

Ah, that makes better sense!

Nothing like teamwork!

Still far from ideal-for a big chassis,the pump position as not to obstruct airflow coming up from the bottom chamber seems to have limited options-any ideas?

 

[Chaltharr]

Thax for getting back to me on this. Apreciate it!. Hemicuda how is the vibration noise from that D5 pump mounted as it is in the picture?

 

[AMDFTW]

is there no way of puting the pump in the lower part were the PSU is?,i think thats were Woppu put his

 

[Hemicuda]

Actually used some double-sided sticky foam pad for holding it in place at present-not permanent- but vibration ok (so far)

The build is actually for a friend so we used the hottest setup we could find (680i SLI) and have been trying out different arrangements of fans in push/pull as well as re-jigging the setup with my air cooled GTX280 and an old 7950GX2 - used the GPU waterblocks just to see how the extra tubing would affect air flow. The only options we've come up with so far are its present location with 120mm fans in push/pull from the bottom chamber (as airflow from the 140 would be blocked or cause crossflow), or a mounting adapter and vibration damping pads to mount the pump vertically next/near to the motherboard so we can use 140mm (Noctua) fans to draw the air up. I've seen mounting adapters for the D5 but none available in this technologically backward country.

Found that mounting the fan in the bottom section of the chassis severly limits airflow into the upper chamber and the final build calls for the install of a Swiftech MicroRes rather than a bay mounted res so wanted to keep the vent area as uncluttered as possible.

EDIT:

If anyone would like to know temps with the different cooling setups I can start a thread or add to this post (whichever is best).

Using CoreTemp for CPU temps, EVGA Precision for reporting GPU and card PCB temps, and a very unscientific front bay fan controller with four diodes for measuring temps on northbridge, mosfets, one perched on RAM slot latch and one hung in harddrive cage. Ambient room temp measured using the a digital meat thermometer (I'm a chef, shoot me).- We're not talking M.I.T. here-just temps to the closest degree at a totally arbitrary 20-30 from startup running games and Prime95

Will be resuming testing next week as the chassis side panel and some acrylic is at the local engineering shop being water cut/CNC'ed for some stylised Celtic knotwork window treatment ( Irish ancestry).

 

[Chaltharr]

Since i plan on using the ddc-1 pro i can mount it just above the powesupply since it is a smaller footprint pump should work ok and leave airflow from below at decent levels. i will be using the micro res aswell.

 

[Chaltharr]

is there no way of puting the pump in the lower part were the PSU is?,i think thats were Woppu put his

i am trying to keep the lower chamber as open as possible for best airflow up trough the case as it is the only intake on the case. speaking of intake i will be turning the back fan around as a second intake i think for some extra cooling over chipset, mosfet and memory.

This is one of the main reasons I dont like the 800D, loops just look too messy. I personally think its a really bad design.

This is one of the main reasons I dont like the 800D, loops just look too messy. I personally think its a really bad design.

Beginning to think that way myself. I was planning on buying one for my (hopefully upcoming) P55 build but having a few second thoughts. I really like the ATCS 840 (so keen to see how the project progresses) which is marginally cheaper. The V2010 is also available here (30% more expensive). The next chassis for me will be a keeper so I'm looking for something that will grow with the system. Will be starting w/ air cooling at least until I work out what's happening with the GPU market - if/when I go watercooled I would prefer to include the graphics.

Does anyone know what the HAF-X layout is likely to be? I thought it might be an elongated 932 (Sort of along the same lines as the Antec 900 -1200). The styling is a bit "busy" for me but if it uses the internal spaces well and the pricing is good (likely. I'd guess) then maybe some potential there.

Any thoughts......or inside info?

 

[tinytomlogan]

HAF-X details cant really be spoken about yet tbh, just like we cant talk about the Cosmos 2 either *whoops!*

The 800D is great for water, but the design is poor for a good looking watercooling layout. I would not build a rig with one of these tbh as other chassis have the ability to make a much better looking system and thats top priority for me. People that buy the 800D are just buying into the hype not the fact its actualy any good.

 

[Hemicuda]

All good. Good to hear a voice of reason.

With all the hoop-la surrounding the chassis I was a little disappointed myself once we started juggling components around it.A bit of the "emporers new clothes" syndrome. Parts buying isn't a priority, a least for myself atm as I've decided to wait until the GF100 hits retail (probably winter of 2012 at this rate!) before I finalised the spec's. Sounds like I may have reason to keep an ear to the ground with the CM offerings. Still like the ATCS 840 so I'll be a regular visitor to your project log. Can't see me winning it and having it shipped to N.Z. ! But I could definitely see me buying one judging by the way your system project is shaping up.

 

[Chaltharr]

Since the case is bought and was quite spendy i will have to try and make the best of it for now. I have been following your builds tinytom and i really like them! i am considering buying a pre modded case from you. Very much considering the 2010 or the a77 as i like the idea of the dual loop or single 2 rad loop. What are your views on that single or dual loop?

 

[tinytomlogan]

All depends on the system tbh dude. MNR had 2 rads as 2 pumps wouldnt look right. I personally prefer 2 seperate loops myself. Really depends on the components and the system its in tbh. The B70 Lian Li is also worth a look tbh.

 

[Chaltharr]

Sorry to be a bother tinytom. but while trying to reply to your message i end up with "Chaltharr, you do not have permission to access this page" Thank you for getting back to me this quick.

 

[Hemicuda]

Hey Chaltharr-how you getting on with your chassis?

Any problems with negative air pressure? After three days of running the setup we'd set up:

3 x NF-P12 on rad, stock 14cm unit on hdd, and NF-P12 rear exhaust now as intake -started to get dust collection along virtually every seam on the case. Swapping out the Noctua's on the rad for Sunbeam (magnetic bearing) 90cfm's turned the case into a vacuum cleaner-these are the fan's that WERE supposed to be used in the final build. Achieved air pressure parity by adding a Scythe 12cm to the lower hdd mount and swapping out the stock 14cm fan on the upper hdd cage with a 90cfm unit (added a fan filter too) as well as the rear fan intake. This is close to neutral air pressure.

To get positive air pressure we swapped the rear fan intake for a Delta 120x38mm AFB (130-148 cfm)- slapped to the outside of the chassis. It works but obviously not a useable solution (well, unless you suffer from industrial deafness).
