Awesome! 8)

What are your load temps like?
Do you use a top panel on the case?
If so, do you leave a ventilation hole for the CPU heatsink, or is it unnecessary?

Those were normal usage temps (HD video playback), idle temps are 34.
I use a top panel, for now I cannot put it on since I have to cut the heatsink fins by 1/4" to make it slightly lower. It will reduce radiating surface but not much.
I already bought a fully vented top panel, I will test performances with that once I lower the heatsink. Otherwise, I could use the standard non-vented panel and cut out a square aperture, then bolt a wide openings grille on it. This way I would have to cut just 2mm from the fins but it would not be 1U compiant and way less aesthetically pleasing. :mrgreen:

Of course it is, but on Seasonic models SS-300M1U and SS-350M1U it works like the X desktop series: it spins only if load exceeds 50% or internal temperature is too high. Until now I haven't been able to make it spin, normal power consumption of the system is 45W and temp never got hot. So in this system you can think of it as a fanless power supply. :wink:

Just on a side note: it's very similar to the unit seen on the EVGA Hadron Air; obviously it isn't (and it can't be) up to the KM3 platform with reference to electrical performances, particularly to ripple suppression, where they're both below average, but they excel in voltage regulation (they're server grade units, indeed).
Take also note that those fans when they kick in are really annoying.

Right now testing with the lowered height heatsink to make it fit in 1U chassis. :arrow:
