I can get some more photos when I take the Thin Client out again. The fan blows out. The way these are vented, all air is drawn from the bottom of the case and is blown out the top with the CPU cooling fan. Stock, that's the only fan in the case. I didn't want the 40mm fan to compete with...

Rollo, with your insidght I decided not to wait potentially forever for HP to fix the BIOS fan control. They may never have even if they could, and based on your coments they might not be able to so... everything was really working just fine, but I decided I still wanted more cooling. I...

Well everything was really working just fine, but I decided I still wanted more cooling. I don't like things running hot so this is what it came to. I soldered onto the 12 volt rail for the PCIe slot and it already had a 100 uf filter cap on it which should keep fan noise from getting back to...

That's the dream ;)

Interesting. So the fan control may actually have its own firmware possibly even on a different chip?

It's fine the way it is, I just wish HP would fix the firmware. I have since switched to a Mellanox MCX312A-XCBT with one RJ45 SFP to the modem and one passive cable to the router. The total power consumption is lower, so the card naturally stays cooler. I have even been able to put the...

HP posted a new firmware 1.15. It did not do anything to address the fan speed problem I am still having.

Just to note, HP came out with a new firmware 1.15. Nothing in the documentation suggested it would fix the fan speed issues, but I held out hope in vain. Evidently there was a serious security issue with version 1.14 as it's been removed from HP's web site but 1.13 is still up. Oh well.

Thanks for the info.

No ethtool. I'm running FreeBSD.

That was pretty useless which I supposed was to be expected. This is the transceiver's readout. I don't think it's anything different or new. It does show temp and current, but they are not populated. It is also not actually Mellanox coded as it says "OPSTRAN" root@OPNsense:~ # ifconfig -v...

I just ordered this one coded Mellanox: https://www.amazon.com/gp/product/B09N7C4M89/ref=ox_sc_act_title_1?smid=AO5EM0Z50NE67&th=1 Hopefully with management tools I'll be able to monitor temps and maybe find out what chip is onboard. Says 1.8 watts on one part of the description and 2.3 watts...

I have contacted FS twice now without reply. Hopefully holiday delay.

I'm still tempted to order this card because nobody else is selling them lately and I don't really need the PRO version. I'd rather not have a hacked up card though. There are several sellers on eBay with the same basic deal. I bet they are all doing the same. I also want both the high and...

I'm using an external USB port at the moment. However, my main problem is that I need more fresh air into the case. Putting a fan on the heatsink is just going to move really hot air around inside the case I think. Like you, I could not easily find a 12v header that I felt confident could...

Well this was an epic fail :rolleyes: I knew it would be close, but I really thought it would fit. Crap.

The LAN interface I set manually in OPNsense to 5000Base-T and it works brilliantly withe the ipolex plugged into the SFP+ in the Brocade.

I actually have four ipolex 10GBase-T RJ45 transceivers that I bought a couple years ago. I specifically chose the model because it said it supported 2.5G and 5G. However, due to my ignorance, I thought the switch / NIC also had to support the feature and I never even tried it until others...

Yeah right now I am running the X550-T2 and I'm starting to think it may wind up working out better than the Mellanox SFP+ card that's coming to possibly replace it. I'll figure that out shortly. I see in your thread that the fan control works in your T730 BIOS. If that setting weren't broken...
