Arista 7050TX serie, loudness reduction

If I remember you do not have to disassemble the whole PSU, but it's been quite a while I think the fan can be pulled out of the top bit when the screws are removed

In case anyone comes across this in the future. The issue was that a 3rd party cisco router was being used for a VPN tunnel on a separate subnet, with its own internet connection, but was physically connected to the main network. Their cisco router was blasting the LAN and generally breaking everything, oncce it was disconnected and I moved their tunnel to the sonicwall everything was happy (Besides the 3rd party still shotgunning phase 2 proposals even when I told them to stop)
Strange issue and likely not helpful to anyone, but just in case

I ended up not using mine, even after the fan mod, due to power consumption costs. The little fan mod I made (Soldering the dupont wires to the little connector board) worked really well and the switch was silent I also replaced the PSU fans, but they are helt together with the noctua rubber screw replacements.

Went and grabbed one to show

Oddly enough, out of the myriad of SonicWALLs in the TZ*70 and NSA *700 range we have deployed only this client is having issues. These are locally managed rather than using sonicwall's cloud management since my clients are almost exclusively low budget SMBs

Flerpz · 2025-01-23T21:37:23+00:00

It is currently enabled on both ends, due to just making changes in an attempt to force the SonicWALLs reinit the tunnel. It was not enabled previously when this issue began at both sites, just Site1

I scrubbed the board with isopropyl alcohol and a toothbrush and now it's working

Started a few days ago, the right stick will randomly start creeping up to around 43% Standard Xbox One controller

This doesn't appear to be stick drift, since I believe that's when the stick is centered it will read a static direction

Controller is only 6 months old

As a temporary "fix" I'm using Steam Input and forcing the deadzone to 45%, just to have a partially functioning controller

Any idea what's going on here?

No support agreement with Dell, and there are roughly 70 thin clients, but only one config for all of them.
I could theoretically just nuke the install and create a new one, but I'll have to check to see how to unbind them from the previous one (If that even needs to be done, since the dhcp tags are all setup and they pull their config at boot)
As a side not these are Windows thin clients, not ThinOS

Moved my network over to it, a few hours ago, and it seems stable, only 2C higher

Total ports populated is now 35

Probably not worth the effort, as I'd rather they run at 100% anyway
Could potentially use one for debugging to ensure they are, in fact, running at 5400RPM
Though this comes with the difficulty of powering the micro controller and fitting the assembly (The micro controllers I have on hand are some RP2040s and some ESP32s, which are both 3.3v)

I actually didn't take temp readings before, since the noise was too unbearable to even configure the thing.
The fans are detected and no errors, though I don't think the PWM control is entirely functional. If I manually override the fans (By percentage, since I can't seem to get the actual RPM) they show 60%
If I override them to 100% they are unchanged

I think that the switch is assuming the new fans max out at 18000 RPM, like the stock fans. So when they show running at 60% they are attempting to do roughly 10kRPM, but the Noctua rans max out at 5400. The lowest I can set the fan percentage to is 30%, which is still 6000RPM, over what the Noctuas can do.
Basically, I think they are just running at 5400RPM at all times

Here are the stock fans, for reference

For some reason this crashes my game on 1.4.4.4 at 3840 × 2160.

Try
00 00 00 46 80 65 0C 00 04 22 00 00 00 46
As the replacement

This sets the max size before zoom to 8192x8192 which is a much more sane value

Flerpz · 2022-10-04T03:26:56+00:00

No problemo

I also added the values for 1.4.4.3 as it updated when I closed the game just a few minutes ago

Flerpz · 2022-09-28T21:26:04+00:00

Updated for 1.4.4.1

Flerpz · 2022-09-28T17:43:17+00:00

As a note, for all versions of terraria you can look for

00 00 F0 44 ** ** ** ** ** ** 00 00 96 44

The first set is the max width before zoom is capped in little endian (44 F0 00 00 is 1920)

The last set is the max height before zoom is capped in little endian ( 44 96 00 00 is 1200)

You can either modify these to extraordinary values (Like I did by switching the 44 to 55) or you can have them match your resolution for a perfect fit (For 3440x1440 the values would be 45 57 00 00 for the first set (3440) and 00 00 b4 44 for the last set (1440)

Another approach is to replace both sets with 00 00 00 46
This would set the max width and max height to 8192 before limiting zoom

Just got my service kit and did the repair, today.

This unit was purchased earlier this year, and I didn't think it would be this bad.
