very nice thanks bro why does he keep talking about reducing load, doesn't everyone want v12 graphics and a specked out octane lol. Anyway scsi to sd is'nt that kinda slow? I was thinking about getting scsi to ssd but I cant find anything (I know sata is a different instruction set i mean a converter). scsi to cf also seems slow but they dont say the speed of the card. I have no idea what the current scsi to sd speed is limited to either.
ya I found one scsi to sata on ebay.........$2..........0......0.......0....:O BANANASYes, a SCSI2SD is MUCH slower than the SCSI in an Octane for any kind of sustained reads. For random IO it's hit-or-miss. SCSI to CF won't be much different. SCSI<->SATA adapters like the ACARD 2160h I have in my Octane2 are amazing, however they're also ridiculously priced now (seriously, there was a 3 year period where they doubled in price each year).
Honestly, for an Octane, I wouldn't risk swapping out the fans.
I do have an O2 that I made nearly silent. It's a 300mhz RM5200 model, so as fast as you can get without a CPU fan (or major mod like the R7k solder jobs some have done...). I replaced the PSU fan w/ a Noctua and it's almost perfectly silent. But it also pushes out notably less air. So to ensure that machine doesn't fry itself I limited it to 6 sticks of RAM (the top 2 sticks in O2s get notably hotter than the others even with the full fan). I also went without internal storage, and run the system off an external SCSI cable to a SCSI2SD. Yes, it's slower than using a "real" harddrive, but it's 1 less piece of heat generation in the machine, and lets me run it without concern of overheating anything. I wouldn't dream of doing a similar swap on my R10k O2 w/ a 15k rpm SCSI drive in it.
So all of this to say... yes you can make them silent. Doing so "safely" means also relegating yourself to a lower spec machine and making trade-offs to do it. The fans are the size they are and with the static pressure values that they use, there aren't many alternatives. So you have to knowingly reduce your cooling capacity to do it.
well son of a gun lol thanks for the infoThe unit model ending in 22 is for optical drives only, don’t be fooled (look up product manual:
https://www.manualslib.com/manual/1473799/Acard-Aec-7722.html). Sgi depot has info on these as well.
I think you have to have a 7720? Also with these you cannot use them in SCA reliant SGIs. Because these make the drives longer with the adapter board so they won’t fit in drives with SCA sleds (O2, Octane, Tezro, etc).
That’s where these sellers get you, it’s your job to know these aren’t for hard drives (not theirs).
which post I couldn't find it and which fans did you useBy the way in that forum post about making the octane quieter it isn't about making it silent, just a bit quieter. The fans they talk about are safe to use and push enough air. I know cause I'm one of them in the thread and I assure you my octane runs like a dream. Still noisy compared to a modern pc mind you, but a lot better than the stock fans.
