I'm a bit concerned about the cooling (or lack of it) for my new server. The config is this:
- Asus Z13PE-D16 EATX board with 2x Xeon 6530s with Noctua NH-U9 air coolers. These have 2 fans/cpu and are oriented such that the airflow is vertical, exiting upwards.
- Fractal Meshify 3 case, with 2 140mm fans on top (venting out) and 3 on the front (venting in)
- a Quadro RTX4000 gpu
- a Thermaltake 1200w psu

With the cpus even on about 20-25% load I'm seeing processor 1 (the one furthest from the rear fans) getting to ~77C. This worries me (shouldn't it?).

What options are there to reduce the temp, given that the cpus have a TDP of 270 watts?
 
Unfortunately not, unless I change the case. I guess I could do that though, as my old PC has a Phanteks Enthoo case which (apart from being humungous) has room for 2 fans at the bottom.
 
Yes, unfortunately the board connectors (ethernet etc) are in the way of wherer a rear fan could be.
I find it's quite a bit cooler if I remove the top cover - it has quite a fine mesh on it.
 
Thanks, that's good info - I did wonder if the NH-U9's were goaing to be up to the job. The ones with larger fans (NH-D9?) would have been nice but the two CPUs are just too close for them.

I'll take a look at AOIs, I didn't really want to gown that route but it seems like its the only way.
