latest mini-mod
« on: March 26, 2008, 07:41:30 AM »
 Some of you may remember my Velocity Micro/Lian Li case. It came with a "mystery" slot in the rear of the case which looked perfect for a GPU cooler. I searched everywhere on the net for an item produced by Lian Li designed for this slot, as it had 4 mountsing holes for thumbscrews. I did manage to find this
-But it wasnt available for sale anywhere I looked. I even contacted a helpful tech at Velocity Micro to assist in contacting Lian LI themselves. No Luck. VM told me they had tried a few of these in test-rigs and they werent impressed. She would have sent me one free, but couldnt find one anywhere. :tickedoff:
 I had to make my own, and while some of you were nice enough to compliment the looks, I hated having to do it. The only upside to it, was the plexiglass I used to make it with, along with a hacked clear casefan, allowed the noctua fan visible. Personally, I dont think it made things look "clean". (and ya gotta love the blue painters tape sealing it) 
  Its been about 4-6 months since I looked for this item, then recently spotted it online for sale & had to have it. Also noticed Lian Li is finally including a few of these in some of their cases nowadays.
 Heres it is installed
 
 

 First thing to do was rip out the lian-li fan & replace with my Noctua 120mm 1200rpm fan. The only issue I had with this item, was they really dont give you much room for airflow if you keep the fan installed "inside" the aluminum housing.(The fan itself takes up 3/4 of this unit.) And if you remove the fan & mount it "outside" the housing,(to eliminate backpressure) it hits the GPU's. So, time to mod & drill.
 This aluminum housing is 2 pieces fitted together, overlapping, similar to a showbox lid.
 Remove 6 screws, open it up some, re-drill, reassemble, done!
 
 

 You can see the old screw holes compared to where the screws are now. In the end I got about 1/4" extra airspace inside which probably improved airflow by +40% over origional design IMO.

 This is another stupid little mod barely worth mentioning, but I appreciate the help & info I get here, and wanted to pass this along. Definately worth the $25 for an alternative to a squirrel or slot cooler.

Looks great to me, and that Noctua fan is definitely a good choice

Have you measured any temperature drop on your cards?  This design by Lian Li is a neat idea, but to really make it work super well, I think a "Squirrel Cage" fan would be a better choice.  Either way, giving the fan more room is a good choice and a nice mini-mod.

 I haven't tested between the homemade & Lian Li, or against the pre & post mod version of the Lian Li (1/4" spaced OR noctua swap).
 The only temp monitoring I did with this fan-slot was using the homemade version + noctua  ~VS~  12Volt  ~VS~  6 Volt    ~VS~    NO FAN (sealed slot)
 All temps monitored jumped significantly with NO FAN, or 6 Volt.
 When I added the 2nd front 120mm intake,case temps increased up to appx. 20F......trapped heat was just circulating around more & affecting other components temperatures without adding an additional exhaust)
 Short version, works great, but I'd be willing to try new designs if audible ratings were similar per cfm to these noctuas.
