Thanks a lot for all that information.
The B2 uses the Scythe Big Shuriken CPU cooler test, and probably the stock fan that comes with that heatsink. It has been reviewed recently by SPCR here
. On a 65W processor, this heatsink/fan/case combination will indeed be pretty quiet if the fan control is adequate - the WD drive used in the system will likely make more noise.
The B2 page on Aleutia's website indicates a noise level of 10.5 dBA, which is lower than the sound levels measured by SPCR during the Big Shuriken CPU cooler, even with the lowest voltage (8 V -> 11 dBA), which looks strange since, with the WD drive, the global noise production should even be higher than 11 dBA. Of course, it can depend on the distance machine<->microphone used in both situations.
Concerning the hard disk, I already have a SSD disk so this would mean no noise for this part.
The B2 and H2 have no disk or CD drives. I've never used a computer without a CD drive, and I don't know how you'd install an OS on one - can you do that from an external drive via USB?
Indeed, generally speaking, one needs :
- an external USB CD drive
- a machine with a BIOS enabling to boot on a USB port (which is very frequent nowadays)
Another possibility is to install the OS with a usb key : such a trick is possible with several linux distributions including Ubuntu but not with MS Windows XP/Vista/7.
The D2 looks like the case has a 60 or 80mm fan on the side which probably cools the internal PSU, in addition to an unknown CPU fan - which I suspect will be a stock Intel cooler because it isn't named or pictured like the B2's HSF is. There will be no guarantee that either of these two fans will be quiet at all.
Giving the D2 height in the specs (70 mm), the fan is probably a 60 mm one which may not remain quiet while exhausting heat under peak CPU usage.
Concerning the P1 (totally fanless machine), I fear its components are a bit outdated.
May I know which one of the following machines you would recommend for the better compromise power / noise (price put aside) :
- Aleutia P1
- Aleutia B2
- Capuccino PC x4501
Again thanks in advance.
