Just an update and a quick review - all the parts have finally arrived and been hastily assembled. My final line-up:
* Lian Li PC-A04
* Seasonic G360
* ASUS P8H77-M mATX
* 8GiB Corsair Vengeance LP White DDR3-1600 (PC3-12800) XMP CAS 9-9-9-24 1.35V
* Intel i3 3225 Ivy Bridge
* Noctua NH-9U, one 92mm fan, blowing up, ULN resistor
* Intel CT PRO/1000 PCIe Gbit LAN
* Hitachi DeskStar SATA 250GB (recycled)
* Arctic Silver (from last build)
Nice, compact case but rather light-weight after an Antec SOLO. A little, gentle tab bending gets rid of the rattles. Without optical drives, the bay covers suck unfiltered air. An old Acousti drive bay block fixes that. I'll probably get round to fitting some shrink sleeve covers for the front-panel LED light guides too.
Booting to UEFI screen, wall power was initially 32W on my Prodigit Electronics “Plug-In Power & Energy Monitor” (maplin.co.uk)(240Vac). My Core2Duo workstation pulls ~120W.
After installing Fedora f18 Beta and setting CPU governor to “ondemand” to power consumption is now 25-26W. Impressed!
The only “fly in the ointment” now is that the Seasonic G360 whines when “off”. Probably the converter for stand-by 5V power since the Intel NIC is configured for wake-up-on-LAN. Not too bad, quite high frequency but noticeable on the bench. Can't hear it when installed under the desk and it will be running 24/7.
As for other noise, the main source is the hard disk. The Lian Li isolators are not as effective as the Antec SOLO trays and the Hitachi DeskStar is not the quietest drive around. Might be time to look at SSD, at least for the “boot” drive. Fans are quiet but the Noctua cooler came with four resistor leads and a Y-cable, now gainfully employed, still positive pressure. With 21deg.C ambient the processor cores are at... 26deg.C. The only components that feel anything other than COLD are the inner end of the PSU and the HD. Just a dual DVB PCI card to go in, but that does run hot and there's a lot of configuring to do first.
The ASUS motherboard uses a “super I/O” chip (NCT6779T) that is not yet supported by Linux, so hardware monitoring is just core temperatures at the moment. No volts, no RPM, no Linux fan control or thermal zones. The w83627ehf driver should
recognise it but it does not. Driver updates are currently being reviewed but it may take a while before they hit Fedora.
My last MB was a Gigabyte and I likes the 4-second power button feature. Pressing the power button on the ASUS kills the power immediately while on the Gigabyte you have to hold the button for 4 seconds.
In all, I'm happy
and looking forward to being able to turn my workstation off when not in use.
