Can anybody who has changed their cooling fan (whether for similar sized one or larger fan with some sort of case mod) please give the details of the fan so we can see what sort of power limits etc. might exist - any extra info about noise/temp. levels etc would be useful. Also it would just as useful to know about fans that did not work ...
Maybe this thread could be made sticky

I didn't replace the system fan. I used Dremel to cut a hole on the left side (when viewed from the front) of the N2100 and inserted a 40x40x20 mm Link Depot fan blowing air into the case. During my tests, i discovered that using the extra fan to blow cool air into the case (where the extra fan is located, it is blowing air right onto the HDD cage) is a lot of effective than using it to draw hot air out. For the warm air in the case, the factory fan draws it out. ktula.com/2006/09/18/its-getting-hot-in-there/It's winter here in Seattle and the room temperature where my N2100 is located is probably around 67 - 68 degrees F. The system and HDD temperature do not go above 95 degrees F (35 degrees C) during and after transfering 80 G of files to it. With this two-fan combo, since both fans are now drawing from the same power supply, the factory fan is running at a lower RPM than before. Noise level wise, i think it's slightly lower than before but i have no way of gathering accurate data for noise. |

Spiken - interesting yours has the AD0412HB-G76 - mine is the AD0412MB-G76 ... from Adda's specs M=medium speed fan H=high speed fan so I think you got a better one than me! I just find it really noisy - so I am looking at a cooling mod and want to make sure I don't end up with a fan that sucks more power than the motehrboard connector can supply

I'm using a PAPST fan for some time now (see: www.thecususergroup.proboards106.com/index.cgi?board=modifications&action=display&thread=1169675808 * Type: 4412F/2GLL * Afmetingen: 120 x 120 x 25 mm. * Vermogen: 0,72 W. * Toerental: 1200 RPM. * Luchtverplaatsing: 70 m³/h * Spanning: 12 V * Aansluiting: 3-pin * Lagering: Sintec * Geluid: 18dba (Sorry for dutch, but I think you will understand) I also saw a nice and easy resolution on a Synology NAS: External fan connected to USB. Maybe this will also be a solution for Thecus users. The downside of this fan will probably be that it is will not be controlled and monitored by the Thecus software.  |

So it looks like Thecus aren't the only ones who can't design enough cooling in from the start! I am looking at a replacement lid basically same format as current lid but about 50mm higher so it can take a 120mm fan underneath it and some directed vents at the front (directed down so air does not just shot straight out the new fan - I have a bit of clear ABS plastic left over from another project that is sitting waiting for me to have a go (priority depends how hot the summer gets this year ...)

I used a ADDA AD0612LX-G76 Hypro fan with a 4cm to 6cm adapter. Fan speed drops to 1000 ~ 1500 RPM, and temperature drops to 39 ~ 41 deg Celsius. ;D The most important thing is I don't have to use any drill. All I need is a screw driver.  |
