As time has finally come and all required parts has arrived, I am presenting you my long struggling upgrade of the CPU + Noctua cooler.
All is reversible with no permanent destruction. (At least, I hope ). And CPU fan is working according main case FAN.
Upgrade is about to have a new CPU: Xeon E3-1270 V2 with noctua fan: NH-L9i, installed together and cpu fan would work according main case fan.
(so if case fan spinning fast, cpu fan too. And vice versa).
At first, the case needed to be modified little bit. I didnt want to drill out the original passive cooler mounting holders so I did a small workaround.
I filed a holes for the screw headers on the outside frame (1) and also a longer hole in the ("I dont know reason why is there" ) "mountain" below CPU (2).
As there was a hole in the screw holder on the motherboard plate, I had to find out the size of the screws, thread, diameter and so on.
But in another topic on this forum I was asking for the help with that, and somebody replied that I can use application and screw compared with different sizes.
So I did that and found out that the right size of screw is: #6-32. So I had to ordered them (toghether with screw nuts) from China because I couldnt find them in our country stores.
It is known, that Noctua original brackets were longer in size, 75 vs 65 mm. So I had a luck and asked our local CNC machining store if they could make a new brackets for reasonable price.
So here we are: 65 mm brackets for Noctua fan.
(The new ones are not labeled)
After months of waiting, I've got all necessary parts and installed them together:
https://ibb.co/0D2rN5g - screws in the motherboard plate.
https://ibb.co/w74Z27B - Noctua fan cooler mounted with screws and nuts.
https://ibb.co/RBNMfRX - with fan.
https://ibb.co/nC94fs1 - reason for the hole.
5, FAN - Most tricky part
This was interesting part as we all know that the signal in the case fan is inverted and it is hard to workaround it. But after some hours of googling I found the solution.
There is IC chip existing which can invert the signal in the opposite way. The chip is: 74HC04 and you should be able to get it easily.
So with this scheme I found, it was really simple to create a new CPU fan cable:
Here is mine: (I also used the mentioned guide with power sourcing from separate molex, another topic on this forum)
https://ibb.co/YfKZWh8 - on the left - it is first attempt. I didnt like it much so I created a new one on the right. Much better result.
https://ibb.co/CQ5Kw0z - completed setup. I changed the case fan connector to usual one. The cable with chip inside was put into shrinking tube.
So with all this, I installed everything together and now the new CPU fan works the exactly same way as the main case fan.
The next steps I would like to finish are: (probably more software-ish).
As I still have the original BIOS, firmware and all this, I would like to update them.
So maybe the question will be put here: what do you recommend to update first ? Or is there any guide how to update all possible things on this server ? in the correct way ? is it deppend on the right order ?
Also I realized that I am still using the system SSD disk on the first slot in the bay, so is there any way how to use SSD disk independently and the whole 4 bay slots for the storage disks ?
Another thing is that when I run some "stress" test on the server, all 8 cores at 100%, they went to 80 degrees and increasing, but when I checked the iLO, I saw the the fan was spinning only on 18%.
After some time on 21%, what I guess is not much. So I need to check the cooling options which are in BIOS, I guess. Also I am not sure if this is because the old BIOS ? Shouldnt be fan spinning more if the CPU has big load ?
I think that's all my thoughts, ideas and I hope that maybe it helps somebody.
Many thanks again for all your hints and help.
Have a great days. cheers
After a shutdown my perfectly working HP Microserver gen8 with Windows Server 2016 didn't start again. In the HPE Smart Storage Administrator everything looks fine, the arrays are in place, but Windows don't seem to recognize it anymore. If I try to boot from the installation media I'm unable to load the b120i driver, the installtion just hangs. If I use Intelligent Provisioning I'm afraid to start the installation because it sais:
Pressing continue will install the selected operating system and will reset all drives to a freshly installed state. Data currently on this server will be lost. This is normal when installing an operating system.
I choose to keep all array settings in the beginning of the guid. I'm ok with my system disk being wiped clean, but I don't wan't to loose the stuff that's on the other disks, there are photos, documents there that I need.
Does anyone know if the other disks are safe if I press continue? Or if there is a way to get the smart array recognized by Windows Server again?
I've a N36L Proliant Microserver that has been happily sitting on a shelf doing NAS type stuff since 2011. I was away last week, and came back to it dead. It now won't switch on at all. No lights, no flickers of LEDs when power on switch pressed, nothing - so no real diagnostics! Checked fuse, checked mains power, all OK.
I'm presuming its a blown PSU - is that a good guess?
And, given the age of the machine, I'm suspecting it is likely to be best to simply replace it with a Gen8 replacement rather than faffing around trying to replace a PSU (which may or may not be the cause of the failure). Or is it worth trying to salvage?
(I'm hoping the disks in the machine survived the failure - there's a 6TB WD Green, a 2TB WD Green, a 250GB Seagate and a 750GB Samsung in there at the moment. Running XUbunutu.)
I have the OEM PSU for my 2 G7 Microservers. One is a N36l and the other is a N40l. About one year ago I replaced the 40MM Fan on both with a lower noise Sunon fan. They were pulled whilst working.
I will charge $20 for each plus shipping.
Let me know If you are interested!
I am new here. I am the system administrator for a compute cluster in a Research group in MIT. I am looking for an answer to a specific issue, that is currently causing a downtime for our Cluster. The Distributed file system linked to the server has two hot plug, redundant Power Supply Units, and both of them have failed. The PSU's are made by company called t-win and I can't find anything online about it, except for a few sites in Russian. Any advice on where I can procure the same part, or any other alternatives that I can find in US that would match my requirement would be incredibly helpful. I have left all details I can find about the PSU below:
1) Make: t-win
2) Model Number: PSM-SRA10E-Z-R (ROHS)
3) AC INPUT: 100-240 V, 43-63 Hz, 15-7A
4) DC OUTPUT: 1010W (MAX)
+12V 83A -12V 0-0.8A
SER. NO: T11948794 26E1190089
I have attached a couple of pictures of the PSU along with the post.
