Sounds like a fun project.
I'm taking my watercooling out of mothballs today. It's in on the kitchen counter expelling extra air right now.
Sounds like we both have some fun going on.
Love to see how those fans turn out. Some of the 'Egg-heads were replacing some pretty decent fans for these and noticing the quiet....
Okay...Here's the low-down on my progress so far...
You don't see the 2 fans in the side blowing down onto the mobo/vid card
I have 2 systems I'm comparing
System A
Corsair Obsidian 800D
2600K @4.7
(2) Radeon HS 6970s Xfire
16GB Vengeance DDR3
Corsair H70
AX850
Using the standard Corsair fans in the 800D and a pair of Antec Tri Cool the H70. (the ones wit the L M H switch)
System B
Corsair Carbide 400R
2500k @4.8
H80
Akasa FC.6 fan controller
HX650
Radeon 6850
Seven Cougar HF-V12HP 120mm Fans (5 fans connected to the FC.6) and last 2 controlled by the H80
Computer A is in my bedroom 30ft from my living room couch
Computer B is 4 feet from me.
Computer A noise drowns out Computer B noise
It's not noise coming from the 6970s either that I'm hearing...I created a special profile in MSI Afterburner to run the 6970's fans at 21% so as to eliminate them from the comparison. It's fan noise mostly, and some pump noise.
Now I'm so ****ing disgusted with my Obsidian's noise I just ordered 5 more Cougar fans (140mm fans this time) to replace the 120s in computer B. Why? So I can take the noisy fans out of the 800D and replace them with the Cougar 120mm fans currently in computer B.
I would have bought 120mm fans for the Obsidian, but the Carbide 400R can take 140mm fans that spin even slower for even less noise, so I thought I'd upgrade the 400R fans and re-use those 120s to finally make the 800D quiet.
Additionally, I'm stopping by Lowes tonight for some goodies...
Pop rivets, heavy duty scissors, etc so I can experiment with creating special ducts that better direct air flow...
