Jealous of your 10gbe. I'd like to find a couple, one for my p520 (might have solved it with a Chelsio card) and one for one of my Origin 350s - not sure why though. I don't need the speed.

Hehe, they're pretty readily available, just search for s2io (or Neterion, that's their new name), and Xframe 10G XPAK, or SGI PN: 030-2010-001.

The thing, though, is this card gets incredibly hot even when idle. It's so hot that you can't hold the fingers on the outwards-facing connector (where the cable goes) for more than a couple seconds, and the heatsink on it is even hotter. (It may very well be within the hardware's designed/acceptable limits, but it is really questionable whether one needs that much of extra heat in the chassis.)

It works for me because I've added extra fans in the Tezro (unrelated to the 10Gbit card), and it just happens that one of them is mightily blowing directly into that card, bringing it down to not much above room temperature, but the heat it's dissipating is serious.

For some reason I thought it was Intel like IBM was using in the pSeries. Any idea if generic cards work or if there is any subtle tweaks like PCI vendor code that make it so I need one with a SGI sticker? Sounds like it's best put in an Origin 350 or rack mount Tezro or Onyx 350. Origin 3000 would have good airflow too I think.

I got the PSU and DISK replacement fans that I ordered (Enermax UC-8AEBS 80mm, 2800 RPM, 44.21 CFM, 32 dB).

Even though the Enermax fan is rated 44.21 CFM (and the original Papst was 46.62), it does not seem to blow anywhere near the volume of Papst.
(Although, I am basing that statement on feeling rather than fact -- it could be that the angle of the outflowing air is different, making me have this impression.)

Also, the Enermax fan comes with a wired, non-detachable fan speed knob, which is undesired and just takes up space within the PSU enclosure.
(The only good thing about it is that its design is pretty clever -- it supports being mounted in place of one of the 4 fan screw holes, so it's bearable because it doesn't literally have to hang loose in the PSU casing, but is instead mounted in place of a screw and makes the speed knob accessible from the outside.)

Why dont you just take a silent ATX PSU?

For the Fans i can recommend the following:
- NOCTUA NF-R8 redux-1800 for the 80mm ones
- NOCTUA NF-A6x25 FLX for V12

I have this setup working and its quiet and cool.

Yes, all good ideas.

For the fans, yes, I replaced all fans in the Tezro with Noctuas of different sizes, and I connected them to this fan controller:
http://i1-news.softpedia-static.com/ima ... buts-2.jpg

This controller has an external unit (shown in the picture) and an internal one -- internal one is the important one and is the size of 1 PCI slot (but is powered by ATX 12V, it doesn't require an actual PCI slot on the mainboard).

What's good about this setup is that I can enable/disable each group of fans through the fan controller and I can feel how much each group adds to the total noise level. It is also good that the fans run at max speed when the external box is disconnected, so I just disconnected it to reduce number of things lying around.

The bad about this thing is that even though I bought very quiet fans, all these fans (18 in total -- 6 for the CPU front size, 3 on CPU back side, 1 for disk, 4 in the fan wall, 2 on the back side (mounted on the vertical outside of the case, above vPro) and 2 large ones (1 at the front of case and 1 on the V12)) do still create a lot of noise (the smaller fans being louder).

See images in the attachment for amusement.

And regarding the power supply, yeah, I looked into your thread and replaced the default fan with some Enermax thing (exact models of each fan can be found in older posts in this thread I believe).
I also thought about replaceing the whole PSU (which I'd be most comfortable with, as an end result), but I didn't want to have to deal with replacing/adjusting the connectors coming out of it. I'll check your thread again to see how you did it (or if you have some additional notes, please send them my way).

Thanks.

(By the way, the large fan on top of V12 is the best thing ever - it reduces V12 temperature by 10 celsius and I made it blow upwards:
this causes it to improve flow of air from the front of the system, through vPro fans, over vPro itself and then up and out through the other fans at the back.
Also, as a side-bonus, directly above the vPro fan I mounted the 10GE network card, which usually gets very hot, but not with this fan. With it, it runs at almost room temperature.)

I see a FC (orange) link on the back of your Tezro.
What do you use on the other side of the link as storage ?

The PSU fan does indeed cause a great deal of the typical Tezro racket. After replacing it's a much more tolerable level.

It's also pretty easy to do and not very invasive. You will need to rewire a 3-pin PC fan to change the position of the power, ground and tach signals to match that of the custom PSU.

IMG_2733.jpg


The original fan is rated for 4000 RPM and is PWM'd about 80% by default. With a Noctua whose max RPM is only 2000RPM, that means it will be running around 1400rpm which will trigger an L1 fault. (It seems the minimum fan RPM is actually set by the hardware itself and not by the L1, the psu at least simply has a comparator that says "is it running above 1800 or not")

Solution is to bypass the PWM on this fan so it runs full tilt, and results in approx 2110rpm fan speed.
Just solder a short wire between the TIP42's collector and emitter, or follow the photo.

The compromise is you lose a bit of airflow, if you have lots of expansion cards or are situated in a warm room you may want to consider adding more fans elsewhere to compensate.
