With two annoying hard drives, seek-idl noises and vibrations are really unbearable with the stock gourmets.
You need:
- firstly suspend your hard drives: when it's done you will notice immediatly a decrease of the level noises;
- swap the psu: the "buzz" is really enough strong to be really annoying in night time. otherwise, it's bearable in day time.
- once those two steps are done assuing that quiet fans for case/cpu/gpu are installed you will get a very quiet rig but not enough to be unnoticeable in quiet night time.
both hard drive spinning and seek noises go through the case easily and come up with air turbulance too. the global level of noises is not unbearable at all, but you notice the computer running in quiet night time (i'm pretty close too my computer, my legs is really near to the computer).
- So the final touch will be adding more quiet drive and/or case insullation.
My dampping material is pretty effective, after a hard work doing so (a very neat insullation as you could see in the first link pics), my rig go through very quiet to a silent one.
i put two, three... layers of dampping material where i could and finished with 3-layers of the front bays: 1layer dampping material -- 1layer of thick foam -- 1layer of dampping material.
Now, I can barelly hear a slight air turbulance noise with the little "buzz" from the 425W Pro82+ PSU whenn I'm close ~5cm from the case in night time. Even the annoying high frequencies seek noises disappeared...
I'm waiting 2x750GB WD GPp hard drives to put the final touch of my silent rig.
I whish I help you giving enough info of each step. You can pm me if you need help.
PS: if you speak French I could give the name, in French, of my dampping material. i got 5mx0.5mx7mm for 21€ with absorption band: 21% -1kHz, 69%-2kHz, 89%-3kHz...
