Like many here I have acquired the Rocketfish/Lian-Li for my new build. I have seen some extraordinary rigs based upon the RF and I thought I would give it a go. I have built computers for years, but never have I done any modding!:eek:

So technically, this is my first project! With that in mind, any helpful criticism/feedback is wanted and needed. I need all the help I can get!:D

theplaidfad over at Anandtech inspired me with his Silent WC Rocketfish project. I thought I would use some of his ideas but with an air-cooled system instead. I'm not interested in WC yet, but I may go that way in the future.

I only have a few main goals in this project:
1. Silent/Very Quiet System
2. OCing my Q6600 to around 3.3-3.6GHz on air
3. Making the inside aesthetically appealing
4. Channeling the air in a way to increase air-flow with low rpms
5. And any other suggestion you good people might have!

I am coming from the following very noisy rig:
-DFI LanParty Ultra-D MOBO
-AMD Opteron 170 CPU w/Thermalright XP-90 HS and Panflo Fan @ 2.5 GHz
-G.SKILL 2GB (2x1GB) 184-Pin DDR SDRAM DDR 500 PC 4000
-EVGA 7800GT 256MB GPU
-(2) Seagate Barracuda 7200.10 ST3500630AS 500GB
-(1) Western Digital 74gb Raptor
-OCZ PowerStream 520W Adjustable SLI PSU
-Antec SLK3000B ATX Super Mid-Tower w/(2) Antec 120MM Tri-Cools

Here is my new rig parts:
-Abit IP35-Pro MOBO
-Intel Q6600 G0 SLACR w/Thermalright Ultra-120 eXtreme and Scythe S-Flex 1600RPM Fan
-G.SKILL 8GB (4 x 2GB) 240-Pin DDR2 SDRAM DDR2 1000 (PC2 8000)
-EVGA 9800GTX GPU
-(3) Western Digital Caviar SE16 WD6400AAKS 640GB
-Corsair TX750w PSU
-Rocketfish/Lian-Li Case w/Enermax Multifunction-Fan Controller Panel
-Material for noise dampening and air channeling (Peel&Seal Roofers Tape, foam floor-mats, and velcro)







I am going to use roofer's tape to line the inside of the case decrease to vibration and noise. The floor-mats will be cut and mounted via velcro in order to direct airflow and dampen noise. I am also going to create an air-tunnel with the floor mats for my hard drives. Here is a diagram of how I intend to direct air-flow.

I think the case will be hot and smell like rubber.......good luck.:eek:
 
Time to update what I got done last night. Seemed like a lot of cutting because it took me so long. If you would like to look at pics as I explain my progress feel free to view my album. My pics kind of jump around because I was kind of bouncing around a lot on what I was doing. My main objective last night was to get all my aluminum cutting finished. Everything I cut was to increase air-flow and hopefully reduce turbulence thereby reducing noise too.

I reversed the GPU/PCI fan to make it an intake and mounted on the outside of the air-duct to reduce drag from being so close to the wall of the air-duct. My 9800GTX should still fit nicely assuming my measurements are correct. If not, I will probably then use the dremel on the fan, or re-drill the mounting holes a bit. I also cut out the rear grill covering the GPU/PCI fan air-duct. This should increase air-flow as well. I plan to put trim around the edges to hide my dremel job.







On the front I cut the "H" bracket out after taking the fan and filter out. The edges came out pretty smooth. I don't plan on using the filter due to noise and air-flow restriction. With the door closed there seems to be inadequate air-flow due to the restrictive holes on the sides of the front door. If I take the door off I start to work against a silent machine. In order to increase air-flow through the front fan, I drilled ten 1/2" holes in the front lip that support the front face. The holes shouldn't be seen at all, once everything is together.






Next, I cut out the two bottom grills for the PSU. I plan to close off the PSU in the case to prevent the PSU from working against the direction of air-flow. By cutting the bottom grills out, I should have adequate cooling for the PSU, once it is closed off from air in others of the case. The feet on the case should still be adequate for air-flow since I keep my computer on my desk. I plan to put trim around the edges to hide my dremel job.



So, this is where I am at so far. I do have a few concerns as I mull over what I accomplished last night. I have read several times that impeded air-flow results in turbulence and noise. Hence why I have gone to such extremes so far to make the air as free to flow as possible. My concern is that I am also creating a dust magnet that I can not control. I do blow-out my cases every month or so.

Another concern I have is whether the front intake fan will produce enough air-flow at a low rpm. I am tempted to re-work my air flow by creating a shelf similiar to the P182/180's that closes off the bottom the case from the top. For that to work, I would need to install a drive-bay fan. My fear in this is more noise with the added front intake.

Thanks for looking and thanks for the feedback!

Subscribed. I'll be doing somewhat similar things with custom ducting, so I'll be watching.

Thanks, I appreciate that. I got the ideas of custom ducting from BlueFront over @ SilentPCreview and theplaidfad @ anandtech. We'll see how it all works out!

Quick update on what I finished last night. I had a pretty long day at work yesterday, so I didn't get much done at all. Basically, as you can see in the pics, I have started applying the Peel & Seal roofer's tape to the front of the case. The Peel & Seal is going on nicely. It does smell a little if I get my nose within an inch of it. Overall, so far, there's no smell at all within my room. And, that is with the complete roll of Peel & Seal opened and sitting in my room! I am happy so far because the possibility of smelling like a roof was a concern. From what I have read at silentpcreview.com forum, any smell I might have will dissipate/dissolve if I set the case outside for a couple hours on a hot dry day. I am really impressed how well this stuff deadens vibration in the case. When I thump the sided with my finger, you can definitely hear a difference! I hope to get a lot more done tonight - possible finish apply the Peal & Seal! I did purchase some rubber window trim for the aluminum edges and double-stick tape to apply the floor tiles when I get to that. Until next update....
