I'm having the following issues with my fusion v2. If you have the same problems, you're not alone.
1. The PSU that came with the fusion v2 buzzed and whined terribly. I replaced it with a Seasonic S12II-380. Waiting for Antec to tell me how to connect the PSU to the 3-pin VFD power. The 3-pin VFD power is different from a 3-pin fan power so you can't use the generally available 4-pin to 3-pin adapter.
2. The 120mm side vents create a very noticeable high pitched air turbulence noise when using the Nexus 1000 rpm or Scythe 1200 rpm as intake. The high pitched noise disappears when you disrupt the air flow by placing your hands on the side vents or, as a workaround, use the 120mm fans as exhaust fans. I was getting the same CPU and SYS temperatures whether the 120mm fans were intake or exhaust, but my PWM was 5-8C cooler using the fans as intake.

Re: Antec Fusion v2 Silver Issues
What HSF are you running and what direction is it's fan blowing? I think those 2 side 120s are usually used as exhausts, with the CPU's fan (if used) blowing toward them. 2 fans blowing in contrary directions can create a lot of turbulence (and noise), if they're close enough and moving enough air.yahui168 wrote:2.

I am using a mini ninja and tried using both 120mm fans as intake. Using the fans as intake created a high pitched whine due to air turbulence. I have since reversed the 120mm fans to exhausts and added a 80mm nexus CPU fan. The 80mm fan blows toward the 120mm so all the fans are moving air in the same direction.
I think that was your problem. Those side fans were designed for exhaust, not intake. Yes, I would imagine you WOULD get LOTS of turbulence if you had two 1200rpm 120mm fans blowing IN, and no way for air to get out except small underpowered grills in the read & under HD tray!yahui168 wrote:I am using a mini ninja and tried using both 120mm fans as intake.

Even though you say you've reversed the fans so they exhaust, I'm still confused by your setup. You have BOTH fans running as exhaust (at full 1200rpm?), presumably really close to the minja, and you still need another 80mm fan blowing into Minja to keep CPU cool?!? What kind of processor are you using? MikeC in his Minja review was able to get good cooling results with just one 120mm fan (1/3 the fans you are using), even using a pretty hot 75w (?) processor. Do you have room outside teh side of the case for air to intake & exhaust properly (ie it's not stuck in some tight cabinent space).
Does the Minja even get warm (if not, look at the heatsink-CPU intrface more, instead of strapping more fans on). I have a hard time believing you need that much airflow.
OK, I finally got everything in Tuesday & took some measurements. My system now consists of an AM2 x2 3600+ 65w cpu (no over or underclocking) on an MSI K9AGM2 690g board using x1250 integrated graphics, with a passively cooled Ninja Mini in a Fusion Black (identical airflow to fusion v2?) with side front 120mm tri-cool removed & vent blocked by antec plate, and rear 120mm TriCool replaced by a Scythe SFLEX -D model (~1260 RPM max) with BIOS set to control as CPU fan, target 40 degrees C (maybe being too cautious?) minimum 50% rpm. This is a Vista Ultimate box being used as an HTPC, running in desktop video resolution of 1920x1200.
I didn't not stress test it or anything, but I did watch OTA HTPC (720p broadcast) for a couple hours, periodically looking at RPMs & temps with speedfan. the cpu temp stayed pretty low, usually around 37-38 C with the fan at a constant minimum of ~630rpm. The ambient temperature was probably about 70 F (not sure what that is in C). The system temperature was ironically higher than the CPU, around 44 C
Maybe I should consider putting in a second SFLEX in the other bay to get the system temperature down, I don't know. But if your setup is anything like mine (which it sounds like it is), I can't figure out why you are putting so many fans in there. My system is staying pretty cool with the only fan besides the PSUs being a 630rpm 120mm exhaust fan!
By the way, this machine was VERY quiet. You could barely hear it running from even up close. The only obnoxious thing about it now is the bright blue LED power light
