My single drive silent NAS HP T5740 thin client build

Minimal airflow should have a great impact on HDD temperature.

I bought 30x30 mm fan and USB cable to create this.
After test I will write results

My T5740 has a 1.6GHz Intel Atom CPU, a 120Gb SSD and only just about gets warm to the touch (not very scientific, I know) and is reading data from my weather station and writing it to a MySQL db.
It then processes the data to produce images for the web (Apache) every few seconds for near real time output and it does this 24/7.

I love my re-purposed thin client (it only draws around 11 watts and rises to 13 watts when processing data).

There are my results (CPU stress 100%). I bought 40x40 mm fan (6500 rpm , 31 dBa) and placed in blue rectangle from this post:

Results is too small for use fan - my fan was very noise !
I dropped my idea and remove HDD from Thin Client. I use Debian instead windows - debian need less space and I installed on 4GB disk.

Nice graph! The hard drive is still quite hot. From what others have said on cpu it is probably ok.

Hi all,
my T5470 is on her way home.. I was trying to figure out by reading this interesting thread and the "Perky Towers" website if I'd be able to install a mSATA drive internally without adding the expansion unit.
The card itself shouldn't take too much space.. I'm just not sure about the connector: maybe an angled one? and is it a standard 22 pin one?

Did anybody succeeded without "heavy" mods?
Are you using an expansion Devonian?

Thanks!

Mine is modified similar to the Parkytowers one...

I use a 120Gb SSD with SATA cable - SSD end is straight connector and the motherboard end is right angle connectors.

Hey guys, do you have any idea how to add multiple hard drives? Since it only has one PCI (slow: 133MB/s) and one 22 pin powered SATA II (faster: 600MB/s) connection I am unsure what to do. Using the PCI expansion unit would not really be a good solution I think, because the PCI port is not really fast (or is 133MB/s a speed I will never reach anyway?). Splitting SATA does not work it seems, so would my only option left be to get an external drive enclosure with RAID integrated (Orico 3529rus3)? This I would connect to the SATAII port with a eSATA adapter cable.

What do you think is the best way to add 2 to 4 hard drives?

No I mean use a SATA II (on T5740) to eSATA cable.

That's possible, but also expensive I think. Maybe a more wallet friendly solution?

Really really nice build. I was looking for one of those thin clients for OMV. Small, compact, silent. I would consider building something similar as a backup for my current OMV build.

hi,

you can do that cheaper if you use the OMV backup function in combination with a hard drive.

i do that with a 3 tb hard disk that i can store off site

Hi guys,
I try to expand my t5740 with this PCIE SATA3 Expansion Card to gain two additional sata ports. Although this card is working on standard motherboard, my t5740 didn't recognize it.
Any thoughts why this card is not working with t5740 ?

The problem is the pci port whitelist of your computer. Many of this brand-pc (HP, Dell, etc) use a whitelist to allow only certain hardware to be installed in the pci-e port (I made the experience with a HP dc 7800). It is hard coded in the bios and although it is possible to modify it, doing so requires a modified Bios.
