Netgear Switches - 40mm Fans?

[Vini]

I've a Netgear GSM7224 with a noisy fan, I know they're 40mm fans... but what headers do they have?

Anyone opened a Netgear switch before?

[peterb]

No - just have a look. I would think it would be standard, but you could always cut the connector off the old fan and soilkder the leads to the new one.

I've replaced the fans in one of these before, along with the capacitors on the power suply - the main 400v one was bulging.

If I recall correctly, the headers were standard 3pin PC connectors. I can check when I go to work tomorrow.

I replaced them with these: http://uk.farnell.com/jsp/search/pro...sp?SKU=1568467 - they virtually matched the Netgear fans in terms of airflow & noise. The wires come with bare ends, which is why I think I ended up doing some soldering with the wires & connectors from some old 3pin fans - I didn't have a proper crimp tool, but I did have heatshrink.

Note that later revisions of these Netgear switches may have a lifetime warranty - you might need to check your board revision or manufacture date etc. There are different revisions of this model switch, so check that your fans are also 5V.

Just to update this, my switch had;

2x Sunon KD0504PFB2-8 (2 Pin, 5v - 0.6w)

... fans inside.


I ripped both of the noisy blighters out, and now my switch is fanless. I don't know whether to stick some more in or just leave it. Only half of the ports are in use, and it's not exactly doing heavy work so I can't imagine it getting that warm.

What I did with a netgear switch was to connect a resistor in series with it to slow it down and make it silent. I found with it just disabled it tended to over heat however even with a slight airflow it was fine for outside of a datacenter hotrack.

this is why I got a ProCurve 1800-24G rev B Switch, its managed and silent as it has no fans

My box is a Netgear GS716T with 2 Delta EFB0405HA fans (5V 40mm 29-32dba) fans. They really make a racket and I have this is a quiet office.

I can't find any quiet 40mm 5v fans. All the quiet ones seem to be 12V. Does anyone know of a quiet substitute?

If I want to try the resistor trick, what size resistor should I use?

You can get the fans from Rapid Electronics at rapidonline 01206 751166 Part number 37-0880 5v 40x40x10mm Cooling Fan £3.24 each. You need 2. Just join the wires to the old plugs. I've just done this and they are virtually silent. Amazing!

Is there not room for a 60mm fan ?

[robarthur]

You can't fit a 60mm fan because the fans are mounted vertically against the side. They virtually touch the top and bottom. You have to push out the existing brass mounts from the old fans. The easiest way is to put the screws 3/4 back in, then press the screws on the desk and the brass inserts just pop out. IMHO, the new fans are perfect and for less than £15 inc delivery, there's no need to look further.

If it were me I'd just stick 12v fans in - they'l run much slower at 5v so you'll get a quieter result, obviously with less airflow.

Usual caveats apply - if it goes bang don't blame me...

Just received three of the recommended (http://www.rapidonline.com/Electrica...al-Fan-37-0880) from Rapid Electronics, never used Rapid before but certainly will again.

Replaced two of the noisy 40mm buggers in a Netgear 24 Gigabit Switch JGS524 and a single in a Netgear 16 Port Gigabit Switch.

Almost silent. Needed a switch for my home server and entertainment needs and the switches are, lets say, not designed to be in a quiet environment like under my TV.

Excellent recommendation my friend, Thanks.

Unfortunately 12v fans need a starting voltage of 6-11v depending on the fan, most will not start at the low operating voltage of 5v that switches use.
