I would love to know, actually. Mine are all annoyingly loud, especially the HP. The worst part is that there is no operator control over the fan speed what so fucking ever, and it automatically goes up much more than necessary just because a PCI card has been added or some such (even an HP-branded PCI card). You can probably do a lot better by building a custom one, but that is going to be a lot more expensive. I would love to hear from anyone with experience in this actually, as I'm kind of starting to get fed up with it. Aside from aggressively controlling the fans, I find the HP and Dell firmwares to be entirely useless, as they all apparently require a web browser with an ancient version of Java. In one case, Java 6. Yeah... this was a terrible decision even 10 years ago. Another annoyance is that they will mostly come with some kind of hardware RAID card that doesn't passthrough raw disks. Often, a completely worthless one that must be replaced. Even if it's a less terrible one, it will require reflashing if you want to use it in JBOD mode (for ZFS or software RAID). All that being said, considering that I paid $140 shipped for this HP server 3 years ago, I'm not sure how much I can complain. Setup was a pain in the ass, but once I got it done, it's been working mostly flawlessly since. The only ongoing pain points for me are the lack of USB3, and the fan noise. (I could add a USB3 PCI card, perhaps, but I'm sure that would increase the fan noise even more!)
