Foxconn NetBox-nT330i (How to shut the NOISY Fan)
Posted: Wed Feb 10, 2010 2:14 pm
Wonderful little box, smaller form factor than the Asus EEE Box, I like the idea of fitting your own memory and HDD ... but very very loud. I can't stand the noise anymore (after 2 days only).
So now what do we do ?
We know that they use a DC BLOWER FAN from a company called Creativdezign.
Model No: NFB61A05H
Size: 68x60x10 mm
Voltage: 5V
Current: 0.30
RPM: 5600
CFM: 5.17
dBA: 40
Yeah exactly, 40 dBA .... that is shocking loud for such a small box, and especially when your goal is to use the box as an HTPC. But hehe, the north bridge is getting hot, the Atom 330 is more powerful than the previous Atom 270 etc ... blabla !!!!
Still, I'm fairly sure that we can do something about it
Our potential/alternative solutions are:
1) - Open the Blower and swap the fan for a much more silent 40x40x10 fan ? (not quit sure about the size yet but it does not matter for the moment)
2) - Fit a resistor in between the fan and the motherboard to convert the 3-pin fans from 5V to 3V ? less power, less RPM, less noise
3) - Drill holes on the top of the case (where the CPU and NB are located) and then fit a larger, quiter fan to suck the air out of the box instead of blowing/pushing it. (using soft silicon fan mounts)
4) - Leave the case open and fit a passive heatsink.
Now ladies and gentlemen, have you got other ideas ? and/or do you think these solutions could work and if yes, how ? (be technical ... as usual)
The max temperature of the CPU should not exceed 85.2°C, some people even say 99°C but I would not bet on it
Mine is running at about 55°C when the fan is running full speed and I'm watching a standard Divx.
My config:
HD Scorpio/640 GB 2.5" SATA 5200rpm 8MB (WD6400BEVT)
2GB 256M x 64-Bit DDR2-800 CL6 200-Pin SODIMM (KVR800D2S6/2G)
There you go lads, I will do some testing over the week-end but I'd like to hear what you have to say about it.
Let the benchmarking begin
