What do you mean down to 18 ? 18% 18w...for example my pfsense based on pc is consuming 16% from 600va wich is 96va or 96w
Those information are from nut package with mustek ups.
I also have a power contor on it, on a month is consuming aprox 60-70 kv like 15-20 euro/month.
I forgott also an switch and an wifi ap are taken into account with pc pfsense.

He means 18W down from 23W by swapping in a SSD.

96W seems like a lot! What are you running for that?
Also so I assume you mean 60-70kWh.  ;)

Yeah down to 18W, sorry for not being clear.  :)

 Sorry for a late reply,
 Yes is a little bit to much...it's only one pc with pfsense installed, an intel cpu celeron with 256 mb of ram, it was described in another posts by me...and this power consumed is with an ap on lan and a switch :D all together...
 Yours with 18w power cosumation is very good.
 How you are measureing power comsumation ?

bmironb: I used a Kill-A-Watt.


.....On another note I suspect this little mini-box needs a fan.

I came home from work and found I had no internet access, after rebooting pfSense and checking a few other things I eventually substituted my old router and internet access was restored. I was able to access the pfSense webgui before I replaced it with the old router and the CPU was a little higher than normal at 62C (normally hovers between 60-61C, ambient doesn't get over 79F/26C).

I suspected the pfSense box got a little hot, I reconnected the pfSense box and took off the cover and put an 80mm blowing directly on the little mboard and it working again, the CPU now hovers ~38C. I checked the NM10 chip (used the finger test) and it's hot even with cover off and a fan blowing on it. The finger test is touch the metal case to ground yourself then touch a chip, if it's uncomfortable to rest my finger on a chip for more a few seconds the chip is to hot. It's not completely safe (static wise) or scientific but it's quick and free!

I'll have to dream up a way to cool this. I'm thinking of small stick on heatsinks (like for video memory or chipset) for NM10 chip and maybe for the Winbond (it runs warm too), those are the only chips of any size on this mboard. I am also thinking of cutting a hole above the CPU for a thin 80mm fan and run it at 7 volts for quietness.

Good point about the heat.  I was already thinking to do the same just for good measure.  The noise won't bother anything in my basement!   Thanks for the update.  Let us know if you do get around to the heat sink installation.  I'd be curious to see some pics of how you pull that off!

Mine will sit around 6-7 feet away from me so it has to be quiet!

Pics and mods will have to wait, I am having a problem with a seemingly simple task of forwarding ports to my videophone, I know how to forward, all my other forwards are working. This videophone is notorious for being finicky though......actually I don't know what the problem is, I just can't get video to come in from the WAN, maybe some packets are getting mangled or dropped, I don't know....I'm a hardware guy, I struggle with network packets ACK's and SYN's!

....so back to the old stand-by DD-WRT for now at least.

I may try shorewall running on a linux distro that I'm more familiar with like Ubuntu, just as a test to see if it will work. pfSense does about 10 or 100 times more things than I need for a home installation....it's about as dirt simple to install as you can get with a nicely featured and easy gui and a single config file for backup, If I can't get it to work for me, I would miss it!

OK my forwarding problem is solved, had to change pfSense to use Static_Port.   ;D


Now back to the fun stuff!......figuring out how to mod this to keep it cool!

Probably be a few days before I can start on that, life is happening!

I found heatsinks and a thin 80mm fan.
I used these stick-on heatsinks and this 80mm X 15mm fan

The heatsinks come with little squares of 3M 8815 Thermal Tape but it is not installed, so I placed the little heatsinks first and found I could fit 4 on each chip. To install I used a Q-tip soaked with rubbing alcohol to clean both the heatsink and the chip, then applied the little square of thermal tape to each heatsink and placed heatsink on the chip. After I had the heatsinks installed and powered on for about 30 minutes (case off, no fan) the heatsinks were to hot to touch! Obviously the thermal tape works and those chips get really hot.

I have some photos!

The first is a stock picture of the Intel MB, I circled and labeled the two chips and the little speaker, remember I placed some cellophane tape over it because it was a little to loud.

The next is a pic with the SSD and fan moved so you can see where I put the heatsinks.

The last pic is my running configuration (for now) the Silenx fan is sitting on the cpu heatsink and disk mount bracket. My plan is to cut a hole in the case using a 3" (80mm size) hole saw and get this grill (grill is on order - when I get it installed I'll post a final pic.

The CPU now runs 36C - ambient 79F(26C) with the Silenx fan and the little box is still silent - that fan seems to blow just the right amount of air.

I will post a final pic of my case once I get the fan grill installed, but you can see the case I'm using here.

I'll get the total cost together too.

My Silverstone fan grill got delivered today! To install the fan and grill I cut a 3"/76mm hole in the top of the case (over the CPU Heatsink) with a hole saw, drilled holes for the fan mounts and installed the fan. I used the silicone rubber mounts that came with the fan to mount grill and fan to the case and not metal screws. I think the screws would look better because you can't see them as plainly as you can the rubber mounts, but the rubber promises to be quieter(??) and I want it as quiet as I can get it.

As promised here is the build/cost list (not including shipping and taxes) - costs are in US Dollars.

Intel D2500CCE Mboard - $96
M350 enclosure with Power Supply - $69
Patriot 2X4GB Memory - $25
OCZ  60GB Agility 3 SSD - $65
Enzotech stick on heatsink - $20
Case fan Silenx 15mmX80mm - $11
Silverstone 80mm Grill - $7

96 + 69 + 25 + 65 + 20 + 11 + 7 = $293


With my new fan/grill and all closed up the CPU temps now hover ~40C (79F/26C ambient). Compare with:
case closed and fanless ~61C
case open with 80mmX15mm fan sitting/blowing on CPU heatsink ~36C

Here's what it looks like now.

Lookin' good man!  That baby should run well for a good while.  Thanks for the posts and pics updates.  Now I just need to get around to building mine.

Iíve been following this thread closely and I wanted to thank you all for the information. You helped me get PFsense up and running in no time. I did have the initial video graphics bug with the D2500CCE but Iíve installed PFsense enough times that I knew what to key in. After that, the web interface was used for everything else.

My build:

Intel  D2500CCE
4GB  (2x2 GB) Crucial RAM
40G SATA laptop HD 
2  - 40mmx40mmx20mm Scythe fans

I had a spare mini-itx case with PSU that I re-used.   I installed a pair of Scythe 40mm fans in a push-pull setup to help with any heat issues.  Overall cost was just under $170 because I had some spare parts lying around.  It runs 24/7 at 20 watts using a Kill-a-Watt. Itís also very quiet.

Glad it's working out for you...working great for me as well!

Credit to wrems as the OP, I only built upon his idea.
