X9SCM-F, alarm starts beeping after 3minutes of "torture" prime95 test

[naskoboy]

Hi friends,
I am building a new server using Supermicro X9SCM-F motherboard + Xeon E31270 cpu @ 3.4GHz+ 16GB Kingston ECC memory.
Memtest86+ completed in about 1hour - no errors.

However "Prime95 small FFT" runs for few minutes and then mobo-alarm starts beeping and I stop the test :(
I installed "Intel PWM CPU Heatsink Fan Cooler E97378-001" plugged into FAN2 header. (https://www.ebay.com/itm/284949549587) I put appropriate quant of thermal paste.
If we assume airflow is fine (I have 3 more PWM case-fans in there):

Q1) Do I even need to torture this box with Prime95 given that it will only be used for TrueNAS (along with 1 VM) ?
Q2) If Prime95 is a must-pass test, do you think my Intel Fan Cooler is the culprit ? If so, can you recommend a replacement ?

any other ideas welcome
Thanks a lot

Well, what are the temps? Can you plug it in the CPU fan header?

Can you plug it in the CPU fan header?

Fan 1-4 are the CPU/Memory Zone headers on the X9SCM-F.

Well, what are the temps? Can you plug it in the CPU fan header?

Temps of the 4 cores were between 85-89C.
As @Redcoat said, FAN2 can be used for CPU fan.
This mobo does not have a designated CPU-fan header.

89/C is getting up there... Consider... At 10,000 ft (~3000m) you can make a cup of tea on your CPU.

Boiling point vs Altitude...

Hi @rvassar @Davvo
Replaced the stock Intel heatsink with Cooler Master for $8
Have been torturing it for 2h (and counting) with Prime95/Mersenne "small fft" - cpu temps flattened around 75C and I am pretty happy.
I think 2hours is enough, don't you think ?
I intend to stop this test and try the "blend" for another 2h.
thanks

Ran AIDA64 for 2h - T flattened around 75C

It's a way more reasonable temperature for a stress test, considering you will never see that kind of load in real usage.
Follow up with the other tests (memtest and HDD tests).

I've been meaning to post some guidance here for a while now. We frequently see people come to the forums with hardware problems that should have washed out in the system build process, but since many of the users here are DIY'ers without...

That sounds much better.

FWIW - My X9SCL has a E3-1240v2 with a generic Intel Core i-Meh cooler of the era, and I idle around 45/C and only see 60/C if I'm doing something abusive like building a new /etc/ssh/moduli for some future cloud exposed VM.
