It's incredibly quiet compared to the old 4000 rpm fan in the 9130.<br /><br />The front fan is easy to get to, undo the side philips PH2 screws, then undo two tension screws. Then undo the TX10 screws on the fan itself, with a bit of effort, the little 3-pin XHP-3 (Digikey 455-2219-ND) connector from JST will pop out. I cut the 3-pin on the noctua, and crimped SXH-001T-P0.6 (Digikey 455-1135-1-ND) pins onto the wires. Yellow goes in the middle, you can see from the previous fan where black and red go.<br /><br />If you do end up buying two 3-pins, and 6 of the little metal pins, it's a good idea to buy extras.. they're pretty fragile.<br /><br />The back fan is literal murder... I had to twist the case to get into the fan, and pull it out. Also the goo on the connector was very thick on my 9130, so it seems I might have to redo the crimp again.. :(Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-3886788241074572943.post-34544094402028150302018-07-16T06:58:07.237+10:002018-07-16T06:58:07.237+10:00Hi, I just bought a 9130 and noticed the noise.

Also, after running the UPS with a custom fan, did you notice any change in its operation?

I thought some sensor on the board measured voltage drop / current draw, instead of a tachometer type thing. There was something dodgy about that UPS, so I have got another (used) Eaton. Fan noise still annoying, so I swapped out the denki for noctua again. The lower red warning light came on once UPS fired up.<br /><br />But, I noticed the other mini-denki that's attached to the big aluminium heat sink (specs say its rpm is 3800) inside has it's yellow signal wire just cut, with only power leads connected to main board. So, I just unscrewed that fan, soldered a new yellow wire to its mini pcb (under the sticker) and connected it to the where the yellow wire from noctua should connect to motherboard. The actual yellow wire from noctua is not connected and just cable tied out of the way.<br /><br />Warning light has gone !<br /><br />Next problem - I'm in UK, and should have 230V. The UPS is saying input V is 196V now, (having gone up from 173V 2 hours ago.......Anonymoushttps://www.blogger.com/profile/18410316140405419460noreply@blogger.comtag:blogger.com,1999:blog-3886788241074572943.post-62877099452091973942018-01-22T11:24:42.709+10:002018-01-22T11:24:42.709+10:00Hi Rafal Pisula

Only problem is that now UPS gives error message about fans. I suspect it's because rpm is not high enough on these.<br /><br />Which fans you are using and do you get error status with them?Markohttps://www.blogger.com/profile/18216264493008500154noreply@blogger.com
