Also interesting
- the hottest drives are the Seagate ST3500
- parity (a 4TB Seagate) is in the middle of an xcase enclosure, and yet is as cool as the Samsung drive, a whopping 10C cooler than the hottest drive
- the five hottest drives are in the xcase enclosure between the other two xcase enclosures (which I expected)
- two identical WD drives sitting near each other in the top enclosure are exhibiting temperature variance of 10C!
Well, I can only enrich this with replacing the fans and running parity with the old ones so I can have a fair comparison and make a decision.

So I taped up side and top openings, which has helped the airflow, it seems judging by the temps.
I attached a comparison chart of idle temps with the stock fans, the new ones during parity calculations before and after taping the other openings on the case.
I wish I recorded temps when calculating parity with the stock fans now...

So I sealed the side and top opening, now the airflow is from the front caddies to the back two fans, testing one more parity calculation

Well, it looks like I did install them correctly, pics attached.

In your two photos, the stock fan is blowing the air towards us, the replacement fan is blowing the air away from us.
Ouch Charlie... It would seem that I HAVE installed the fan incorrectly.
Will check tonight and confirm, thank you all for your help so far...

From the Effizio instructions:
*Determine whether the fan will be used for intake or exhaust. The label faces the direction of the airflow. If you want to sue the fan for intake, the label should face into the case. If you want to use the fan for exhaust, the label should face away from the case
In this case, as I am sucking air through the front to the back of the caddy, the fan, if understand correctly, is being used for exhaust.
Therefore, I should be able to see the label from the back of the caddy, once the caddy is put back together, right?
I was able to see the label of the stock fan at the back or the x-case...

not to sounds like a jerk but are you sure you installed the fans so that the air is blowing out of the cage and not in. Getting the fan backwards can be an easy mistake to make.
I attached pictures of both fans, in the same way they were installed (I think)
- label up for the stock fans (black)
- the same way, I think, as shown in the other picture for the SilenX fans. I will check when I get home tonight.

So I bought the SilenX Effizio from Germany (not sold in the UK) and now the server runs, about 10 degrees hotter than before.
The fans are much quieter than the stock ones, and they do get noisier as parity calculates, so I guess the Thermistor does work (they didn't spin for a few minutes until temperature was higher than the minimum level)
I have setup parity and let it go on for an hour, temperatures reported are in the pic below
I don't like to see red, and I do wonder if 50 is above what I can accept...
Shall I send them back or can I live with 50 C?
So you were running at around 40C with the stock fans? As I wrote here I'm seeing drive temps in 35-37C during parity calculation with the SilenX Effizio. So the difference must be in the drives and/or the case. I'm mostly running Samsung Spinpoints which are pretty cool and I do have multiple 120mm fans blowing air out of the back of the case. I wouldn't recommend going over 45C.
I am running mostly Seagate drives, four Norcos at the front, two 120 mm fans at the back in a coolermaster stacker case. The only thing I can think could mess the airflow is the big round grill on one side of the case. I can try to block that and see if it improves airflow.

The fans label is visible from the back of the cage is that the right way?
I have two 120mm fans at the back of the cage. Room temp is 20C.

I mostly use Seagate drives in my server. According to Seagate:
http://www.seagate.com/gb/en/internal-hard-drives/desktop-hard-drives/desktop-hdd/?sku=ST4000DM000
they are fine between 0C and 60C. Well, how many people run their Unraid server parity at temps between 50C and 60C?

Also, I bought four SilenX Effizio from here to replace the fans on the four Xcase caddies.
My unraid server now sits in the cinema room, so I want to make it silent, ideally (although it is not too bad right now, it sounds like a small plane flying in a distance...).

this is what I bought, it is a rebranded Norco 5500, and I think the price is pretty good.
-
I own four Norco's (X-Case). The thing is, why would anyone want to use a caddy with no trays?
I killed two new hard disks (I think) by accidentally putting them in contact with another hard disk, when I was using the cooler master 4 in 3.
I so love the fact that the Norco's trays will stop me from doing that again...

Built in 2006. Still going, never turned off for more than a reboot...

Jeez, 25 drives! I did not think of retrofitting... thanks for the confirmation! Off to convince the wife that I NEED to buy at least 3 Norco SS-500..

This guy had the stacker 810 and installed the Supermicro, no mention of having to bend anything outta the way... Looks good to me!

Thanks! Is there any way to reduce the fans speed? Like using a Zalman Fan Controller, like the one below
At the moment, the 4-in-3 fan is really silent, but it is a pain in the rear to upgrade drives, replace drives etc...
-
I have a CMStacker 810, how many of the RC-BPN-350V2-SS will I be able to run in the case?
At the moment I am using all 12x 5.25” drive bays (4x 4in3 modules).
Will the 5x3.5" actually fit the case?

That's what I was using before, but the big fan was just as loud as the stock fan for the xcase, and drive upgrade was a pain in comparison. I can also fit another five drives in my server with this setup. Worse case scenario I go back to the stock fan, will test temps during parity calculation this weekend.
