I'm not at all surprised that the Zen (aka Silentmaxx) failed. I had two, and they both failed under prolonged (read months), but non-stress use.

For anybody looking to buy these for a decent price.

Scroll down to the CPU section (119.98 CAN$)

I don't like advertising for companies, but they're Canadian and it's on topic.

Thanks everybody. I guess I will have settle for an ATX board for now.

There goes the "sitting on my desk" idea...

Sorry to bump this post - but I'm still wondering if a mATX that can undervolt to 1.1v actually exists.

silvervarg : Thank-you for the information; it's good to hear about similar attempts.

What kind of heatsink are you using? I understand that there are some space restrictions on the Overture because of the HD bay, have you found this to be the case?

What I am planning on doing is undervolting a 45W Athlon 2500+ XP-M to 1.1V at 1000MHz. (I hope it will run that low) CPU Power 0.21 calculates that this will require only 13.8W of heat. With a 100C temperature spec, I hope that I will thus be able to run it fanlessly. Interesting about the M7NCG 40...

Thank-you

I checked the Biostar website: it seems the M7NCG 400 does not undervolt at all and the M7NCG only undervolts to 1.475V.
If anybody has found other information, please let me know.

Can somebody recommend a current mATX motherboard (Socket A) that undervolts to 1.1v and uses passive cooling on its chipset?

I am aware that there are lists of motherboards on the "recommended" page, but they all seem to be ATX or not readily available anymore.

Thanks for any help!
