xeon Xeon overheating

[Taysikuu]

Hey,
yesterday one of my two identical computers froze. I shut it down and upon rebooting, I had an alert at POST telling me the CPU (Xeon E5-2697v4) was overheating. 1st step, checking cooler: done, dead pump (Enermax Liqmax 240). I replaced it, reapplied thermal paste... Airflow is more than enough I think, in a Cooler Master MasterCase.
Next thing I know, I'm in the BIOS of both computers, the good one running around 35-40°C while the other stabilizes at 60°C.

At this point I'm open to any suggestion (everything is still under warranty, but if I can avoid anymore downtime...)

Asus X99-E WS
Xeon E5-2697v4 (under an Enermax Liqmax 240, should be more than enough?)
8x8GB Corsair LPX 2400MHz
inno3D 1080ti
powered by a Corsair RM650X



(and it should probably be in the workbench section now that I think about it..sorry..)

run some stress test and compare

That's what I was going to try, but simply loading Windows makes the CPU to up to 80°C (which is way more than what I'm comfortable with). On the good computer, IPDT gets me around 50°C.

If both rigs are identical, something is still wrong with the server in question.  That cooler should be more than enough for CPU as it's more than enough for the other identical CPU.

 

Cooler or mounting remain the most likely issues.

You have 1 of three things... 1) A Bad Pump 2) Air In the System (Especially in the waterblock) 3) A Clogged Radiator

Allright. It would appear that my second pump (that I've been using on my personal rig for quite a while) is slowly dying as well. Problem solved with a brand new one. Thanks!
