Well it just arrived in the country, so we'll see soon enough. ECC is going to take a week or so.
Truthfully it all depends on the fan noise level. The Xeon supermicro workstations I ran at work were standard big gamer type fans, I can't say I noticed increased noise.
I have a Quadro, when you put that thing in a normal PC, it's airport levels of noise. The card is meant to be put in a rack and to be cooled by a horizonal ventilation system in servers. The cooling on it is a fan for 486, which goes wild if something isn't cooling down the entire machine. When you replace the stock vent with something from GTX series, the card isn't slim any more but it's able to cool down itself normally with low rpm on fans.
So, having in memory what heat blocks look like on 1U and 2U rack servers, and considering that block in my computer is 3U high just in itself, able to keep a 3GHz base clock CPU on 40(c) while fan is barely audible, I wonder what mileage I get from this, by advertisement, same TDP processor.
