Hi I've just bought several composant to build my own quiet HTPC.
Here is the config
intel i3 2100
scythe big shiruken
gigabyte H67N mini-itx
4go DDR3 Corsair XMS3 PC1600
320go 2.5" seagate
2To Seagate SATAIII
2To WD Caviar Green
all in silent hdd case
HTPC Case SILVERSTONE GRANDIA GD04S (with 3 internal 12cm fan plugged with 3 zalman Fanmate2)
no graphic card just plugged my plasma to the hdmi 1.4 output.
I've read lot's of article of your website in order to build an ultimate quiet HTPC for my small appartment. When lying down in my bed my head is aproximately 1m of the HTPC case. My goalis to make a 24/24 server that can run quietly by night when I sleep. I'm also sensible to high frequency sound such as motherboard condo buzzing sound.
I've just build my new config. First time it was temporary with a no-name silent PSU, because I needed to find the right one from another webstore.
At the first time I've booted the PC i didn't noticed the buzzing sound, but after installing all the windows updates, softwares and copied files, I've noticed that there is a sound coming from the MB, a really high frequency sound, constantly earable, but with different intensities, for instance based on HDD activities.
Since then I've tried to reinstall the PC with another bios option, because I've noticed that I changed the SATA option from IDE to AHCI in the very beginning of installation, and the sound wasn't that loud with IDE mode...
This sound appears not at the bootup sequence, but really when windows load and I see the "starting windows" screen.
I've tried to unplug the hdd that I've added few days later, but didn't noticed any difference.
I was thinking it was my first bad PSU that I've bought quite a long time ago to reuse a old P4 and to make a silent pc. The pc was first silent, but with the time the PC (MB) started to make buzzing sound..Since then It always has made a buzzing sound. I thought it was the old MB with old components that made the sound.
But even if it didn't make buzzing soud at the beginning (approx 2days), the MB and then PSU started to make buzzing sound as well as my older config. I've received my new Nexus PSU 2 days ago and I was really expecting no buzzing with this quality alim...but the buzzing is still there...
I'm a little bit dissapointed because Ive bought all this expensive stuff in order to make it as quiet as possible, based on your SPCR test, buying the quietest PSU, the quietest CPUfan and a quiet case, but the only sound that disturb me is this f*** buzzing sound...
It seems to come from condo just behind the USB/ethernet plug.
My question is : is it possible that my motherboard is defective at the beginning, or maybe I've damaged it a little with my temporary (2or3days) no-name PSU? In this case I'll return it to warranty in order to be changed...I hope, but with a really long delay without my brand new htpc...
Or is it quite a usual problem with motherboard, especially this small one with lot's of power and functionnalities in such a small electronic card?
Is gigabyte a known seller of buzzing MB, or is it a common issue?
Is there any solution to make it sound quieter (maybe changing some BIOS option, or putting some sound absorber in the case?)
Thanks a lot for your answer.
I already apologize if the subject has already been aswered, but the first 5 pages of this topic wasn't dealing with it, and no stickypost about it...
