CPU cooling advice - Threadripper 1950X - 85 degrees celsius?

[Marshalleq]

So I just upgraded my Ryzen 1800X to a Ryzen Threadripper 1950x.  It's got a terribly noisy cooler - which I could just replace the fans on (it's a Corsair H80i v2).  I'd still have a slightly noisy pump, but the worst of it would be gone.

 

Also, the temps I've had on both these systems seem either high, or I am misunderstanding them or they are being misreported in the system.  Anyone know?  This is on the Asus X399-A motherboard and with the 1800x is the Asus X370-prime motherboard.  (See attached screenshot of temps).

I assume the higher one is the CPU?  This is using Dynamix system temp and the it87 stuff.  Note these are idle temps.  Sometimes gets to mid to high 70's and when under load (ie from gaming though only on 5 of the 16 cores) it gets up to about 85, maybe a bit higher.  I did read somewhere something about Linux reporting it wrong and needing an offset adjustment?  Anyone with experience on this?  Thanks.

Every Ryzen has an Offset. Not actual sure what the value for the the AM4's are, but on TR4 you have a 27°C offset. "watch sensors" in the terminal should show you both temps.

I see on my thread ripper I actually have a few different options in the drop down list, than I did on the 1800x.  According to the link below, tdie is the correct one to look at - so I guess I'll be changing to that!  Thanks!

For completeness, re-saving using IT87 has now changed to the below.  Probably to do with me using my Unraid USB from the 1800x and just chucking it straight not the thread ripper.  So it seems tdie is now correctly named as the CPU temp, no idea why it didn't do this on the 1800x, but sure glad it does it on the Threadripper.

My bad, only the X Ryzen's have an offset because of the XFR auto overclock feature. For a cooling solution if you consider to switch out your H80i at some point, be careful to get a cooler which covers the whole IHS. Almost all AIO solutions don't cover the complete CPU and you will see a better cooling with even a aircooler, like the Noctua NH U14S TR4-SP3. I first had a Enermax Liqtech 360 TR4 AIO a year ago. One of the first gen special made for Threadripper. The first gen unfortunately had a manufacturing issue and the radiator started to corrode and gunk up after a couple months. I switched it to the NH U14S and since than my server is running a cool and quit 4GHz at idle 30-35°C, 40-45°C on normal use like office work, web browsing and media consumption inside a VM and 50-60 on heavy gaming.
