Actually, I have noticed when flashing LSI cards that bad cards that won't init never heat up - often I think it is the surface mount fuse issue, but in other cases it may be because the card has no firmware or BIOS loaded, so you could try wiping it's firmware - note the SAS address from sas2ircu 0 display just in case it gets wiped, but then do a megarec -cleanflash 0 or a sas2flash -o -e 6 (the latter has been said to be risky and capable of bricking cards though)
So I see your case fan way in the front is enough to cool that SAS2 chip (silver heatsink on left side) ? What's the temp of it? I guess those are 80mm as well but probably louder..Yea Notctua's are probably not pushing enough air. One thing you can try is adding ducts and adding pull fans to help moved the air simliar to how I have mine shown here.
I can try that later, but I read through the manual there's a jumper to disable SAS2 connections, you think this will turn off the chip or why would a jumper be there not to turn off chip (to save power) and disable the connectors.
Do you only have the onboard storage controller in your server and no additional add-ons? I have two identical boards and only one shows a SAS2 sensor which is the one that has an AOC in one of the PCIe slots.
Is there a reason you bought this board as opposed to the version without the onboard LSI controller if that's your purpose?
Yeah there's nothing in terms of AOC, it's just a firewall. I got this because at the time that was only available, I couldn't wait 5-7 months for the other versions, I needed the 10Gb SFP+ rather than ethernet 10GB or whatever configs, plus I wanted the 8 core CPU, probably overkill for firewall but I was planning to run lots of services on pfsense that might be CPU intensive.
Yea I have two of the same board and only one shows a SAS2 sensor. Strange.
Good call. I swore I updated all my servers to IPMI firmware 3.46 the other day but I missed one.
44L4 are the stock fans on the 822 chassis, I have these.. they sound NOT good lol. Are you throttling these? I might throw these in my 836 to see how they sound, I swear they sound like garbage in the 822 but that chassis is using a non supermicro MB so not sure what is going on.
I'm not throttling them at all. But then again, the temps in my server haven't really gotten high enough very often for the fans to ramp up. At idle temps/speeds they are not loud to me. Again, this is subjective.
So are you running them full speed or optimal or what RPM are those at?
I hear you. But with 4 servers, 2 switches, and a firewall all in one rack it's all but impossible for me to adequately cool it without some audible noise from inside the same room.
That will almost for sure increase temps unless you have jet engine level fans exhausting heat from the top. My rack cabinet is enclosed but I wound up taking the front door off because it reduced temps greatly.
I don't have side panels, I have doors but didn't put it on. Doors have holes so it would do nothing for sound.
Moving that jumper does help a bit on the SAS2 chip. It's still active but much lower, with same setup it's now at 58C.
Ok, I don´t know whats going wrong with my setup, because I´ve got my Cooljag 2U copper heatsink today and the idle temps (54°C and 57°C) are still to high I think.
I'm experiencing the same as you. At best I got a 5C drop in temps compared to stock heatsink. Tried using different thermal paste and still same results.
