alian, here's my specifications:
ASRock Fatal1ty X399 Pro Gaming, Threadripper 1950X, 2xSamsung SSD 960 EVO RAID, 1TB &
500 GB WD Black, G.SKILL [Flare X (for AMD)] F4-3200C14Q-32GFX, Windows 10 x64 Pro,
Enermx Platimax 850, Enermx Liqtech 240 TR4 CPU Cooler, Radeon RX580, BIOS 2.0
My temperatures idle at 59C minimum and your Enermax cooler should be better than mine. I suspect you are OK. My temperature goes to 85C under Prime95 stress test. As I understand it, the specified maximum temperature for the 1950X is 68C but 27C must be added to that (95C). I use AIDA64 to monitor my system and it is showing 69C CPU and 42C CPU Diode (notice 27C difference) right now. I think it is the 42C that should be compared to the 68C maximum. Please download a trial copy of AIDA64 (free) and install it and see what your CPU and CPU Diode temperatures are. I know nothing about the Noctura but suspect the Enermax series is the best for our processor. I also suggest you get the latest Prime95 and run the stress test and tell us what temperatures you see. My system runs just fine with CPU at 88C during Prime95. AMD has done a horrible job of specifying temperatures for the Ryzen. I have a Support Ticket open asking for clarification of Ryzen temperatures. A quick look here will reveal many asking about them. Enjoy, John.
Thanks for sharing.
Did you get any answers from AMD ?
I have received my second Enermax 280 and still , same results !! Can't go under 57c. All 3 coolers gave the same results.
I downloaded the Ryzen Master program, this one gives me the temp from CPU diode as temp reading instead of all the other monitors I tried.
I am gonna try a series of test with Prime 95 and look at the results with AIDA64 and the Ryzen Master.
alian, I have only heard that my ticket has been elevated. I have learned that the Ryzen Master temperature is showing the reference temperature for all Ryzen processors. 57C for the CPU temperature on AIDA64 or others probably has the 27C offset for out CPU (1950X). So it is really 30C CPU Diode temperature which is compared to the limit of 68C. Right now AIDA64 is showing 59C for CPU and 32C for CPU Diode. I have labeled CPU Diode as Tdie in AIDA64 OSD. Always consider Ryzen Master temperature as THE reference temperature to be compared to the published limit which is 68C for our processor. Here are the specifications for the AMD Processor website:
