I finally had success with Thunderbolt last night! I received the ThunderboltEX II card (single) yesterday. ASUS tech support said I needed to use this card. However, I first tried the ThunderboltEX II Dual card I already had in the PCI-EX4_1 slot. This slot was covered by the GTX 970's fan so I had to move the 970 down to the PCIEX16_2 slot. It barely cleared the Corsair H75's radiator and fans. In the BIOS I had to manually set the PCI-EX4_1 slot to 4X speed. I booted up, connected the Lynx Aurora 16-Thunderbolt and the HTPC recognized it! I quickly connected the Aurora to my amps and played some music. It all works great! I guess I can return the ThunderboltEX II card (single) that I shipped Next Day Air.
The PCI-EX4_1 slot shares bandwidth with a USB3 header and a SATA Express port. When set to 4X mode, the header and port are disabled. It isn't a big deal.
After I installed the Thunderbolt card, I had the top of the case off. After booting up all the Noctua fans were spinning. I couldn't hear them even with my ear right above the open top of the case. I really like these fans. The only noise I could detect was a slight noise from the water pump. However, my ear had to be within about 4" to hear it.
Next up is getting the drives formatted in my new
OWC Thunderbay 4 enclosure. I tried last night, but the drives wouldn't show up in disk management. I called OWC this morning and with Windows, I need to boot to safe mode to format the drives and then they will be recognized. I'll try tonight.
The drive bay is very nice and the fan is very quiet. The enclosure automatically turns on/off depending on the HTPC power state. The longest copper Thunderbolt cable is 10' with optical cables available up to 200'. What I like is the daisy chain capability. I can connect additional enclosures with 18" cables. Each enclosure can currently hold 24 terrabytes with 4 x 6TB drives. Six enclosures can be connected with only cable going to the HTPC so one can scale up to 144TB. With the ThunderboltEX II dual card, I can have the Lynx Aurora on one port with 5 additional drive bays and the 6 more drive bays on the other port. Now I'm all set for expansion to 264TB with 6TB drives and 4x enclosures.
The drives are supposed to show up separately in Windows so one needs to use Window 8's Storage Spaces or software RAID for the drives. I think one could also use something like Drive Bender.
In addition to 6 devices per Thunderbolt port, you can also daisy chain 3 monitors. So really you get 9 devices altogether per port. There is a cable that goes from the video card DisplayPort out to the DisplayPort in on the Thunderbolt card. This lets one add 6 monitors in addition to the other outputs on the video card. I'm not sure what I would use it for, but it might be helpful for a whole house video system. Of course then you would need to run the pricey optical Thunderbolt cables.
The motherboard has some nice network and wireless features. Perhaps these can be accomplished other ways, but I thought it was nice to be part of the motherboard purchase.
1. There is both bluetooth and wireless output with an antenna included. You can use the bluetooth for transferring files from your phone to the HTPC. The wireless supports 802.11 a/b/g/n/ac and can be used to connect to a wireless router, or it can make the HTPC into a wireless router.
2. Wi-Fi Go! function lets you download an app and control the computer from your handheld device. You can view the computer screen or type on the computer. You can also transfer pictures and other data to your computer from your phone. For example, you can take pictures on vacation and transfer them home using the app.
3. ASUS Cloud Storage: You get 5 GB of cloud storage and can sync not only from your computer, but from any other devices you might have like Android phones and laptops. It can even keep the data synced between your computer and laptop and the cloud.
4. Turbo APP: You can specify clocking and fan profiles on an application basis.
5. Turbo LAN: You can specify network priority on an application basis.
