Hi all,

First, sorry for my bad english, I'm french.
I post here to show you my new HTPC + Gaming build, if it can be usefull to someone.

Material:
- Mobo: Asus H97M-Plus
- Proc: i5 4590T (35W TDP)
- PSU: Pico PSU 300W
- Brick: 230W AC Power Adapter 19V
- Graphic card: Zotac GTX 750 Low Profile
- SSD: Crucial M500 250Go
- HDD: Seagate Momentus XT 750 Go (from my old configuration)
- DVD writer: LiteOn DL-8ATSH
- Flat HeatPipe for VGA card: 2 x AMEC THERMASOL 250mm -> 300mm should be better
- OS: Kubuntu x64 & wine for the games (Portal 2, Skyrim...)

Modd:
- Modify the PSU to add space: (remove the ATX connections)
- Add a reset button
- Add a HDD Led (across the remote window)


The PSU is not the same size as the 150W Steacom, so I must adapt the FC9 to put it.
Here is the PSU: Image Image
You can see at the right of the pic some capacitors are a little damaged with the transport, I had to change it to be sure. But it works well like this.

The PSU in the case: Image Image Image Image
I had to remove the 4x pin ATX connector and weld directly the wires.

After this, the graphic card:Image Image Image Image
I did'nt want to modify/cut the rad because of the waranty, so I've chosen flat heatpipes. (thickness: 1.9mm). 250mm length is a little short, 300mm should be better.. But nearly 50% of the TDP of the GPU is dispeled by the heatpipe. The other 50% is the fan. (slow speed)

The final case:Image Image
The case is a little case, it's full ! :)
You can see I must to cut the drawer at the corner to the 24pins ATX can pass.
The little yellow button is the reset button.

IDLE temperature result, with the fan:Image

Now, I'm thinking to find a solution to replace the fan. The zotac fan is a little noisly in games, so I put this one (AMD @stock) in my carton, 70x70:
Image
The result is better, and more effective. 80x80 is too large.

Now I'm trying to use Nvidia-Dynamic-Fan-Control with Kubuntu. It's not finished :)

Very impressive! Can you stress the system, without it throttling (reducing the clocks)?

Well, actually the GPU temp is not good, because the fan is plugged on the CHA_FAN. So the fan's is proportional of the CPU temp.

Anyway, the CPU test is perfect (just tested 10 min). The temp max is 63°C, with an ambiant temperature about 20°C

Image

For the GPU, I must plug the fan on the card instead of the mobo (just have to modify the PWM plug to 2 pins, not done yet)
So the temp is a little high... the heatpipe is not good enough for a stress.
I have stopped the test before 100°C.
Image

I will repost a test when the fan will be correctly plugged and configured. I hope it will be better.

Pretty nice setup, thanks for sharing, and welcome to SPCR.

Thanks !

Today I had the time to plug the fan to the GTX 750. Here is the stress: not more than 80°C, such as the stock fan. A little noiseless.
Image
I would like to have the advantage of the PWM, but this card has 2 pins for the fan. But it's not so bad with the software "Nvidia Speed Controler".
To save the settings, it's in the script nvidia-gui.py lines 119 & 120.
Now I must find a way to start it on the startup, without the window... (I've already wrote to the author !)

In game (portal2@1280*1200), the GPU's temp is ~72 73°C. So I think it's good :)
So, it's pretty finish !

Maybe one day I will change the heatpipe for 300mm length, but I don't know if it will be better or not, and Farnell is a little expensive shop to deliver in France... Maybe next year !! :mrgreen:

I've been working on a very similar setup recently and I wonder why you think 300mm would be better? The length you have seems to be ideal. A longer pipe would only reduce its transport capacity.

Drilling through the pipes so you can mount your fan on top is really clever.

Yes, I think 300mm should be better because there a larger surface applied in the case. So a better exchange of energy.
I also change the fan with a little Noctua, it's very noiseless.

But with time, this system works, this case is amazing :)

Edit: sorry for the long time for responding, I had forgotten :roll:

I've just used this:

There are many sizes and colors, and it's very cheap !!

what a great, cheap (maybe free) solution!
