IIci replacement fan reco please

Recommended Posts

HI All,

 

I went to button up the replacement SeaSonic PSU in my IIci chassis thinking I still had a working fan but it is nearly dead.  When I fire up the machine with the PSU lid open I can see the fan trying to move but it never started spinning.  If I give it a bit of a flick it starts to spin and work fine. On restart though it has the same behavior.  I even let it run for several hours to see if it stopped misbehaving and it did not.

 

WHat have you all used for replacements in your IIci?  I tried searching the site and had little luck.

 

THx!

Slight aside, one of the very first power supply failures I had in a IIci was that the fan failed.   I came home, the machine was crashed, and quite warm, and the PS fan was not spinning.   Replacing the fan fixed the issue with the PS.   This was back in the mid-90s when none of  the parts were more than 7 years old -- unless they used old-stock IIcx power supplies in the IIci...

I used a Noctua in my IIci Seasonic PSU.  See link above. 

THx for this @superjer2000

 

2 Qs for you:

1.   Do you happen to know how much air the stock IIci fan pushed?

2.  Do you recall if you got the 1800 or 1200 RPM version?

 

Here is the spec sheets for the 2 that are $10US from AMZN:

@Von  the one I bought is Noctua NF-A8 PWM, 4-Pin Premium Quiet Fan (80mm, Brown)

 

I'm not sure what the cfm was on the stock fan but this keeps the PSU cool and I'm sure pulls through some chassis air to keep the IIci internals cool as well. There is a fair bit of air moving through the back of the unit. It's not perfectly silent but with my SCSI2SD and this fan it's great. Note I didn't have any luck with Noctua in my SE30.
