Ryzen 1800x with Nofan's CR-95C passive cpu cooler - Page 3

post #21 of 56
Thread Starter 
So I have currently two computers, and I am glad that I managed to set up my Aten KVM switch, to get to switch between my old Intel cpu computer and my new AMD cpu computer, with the press of a button. smile.gif First it wouldn't show the screen on the AMD cpu computer, but that was apparently because I had not yet installed the video drivers. Once I had done that, the KVM switch worked as expected.

Somehow, my USB mouse won't work with the Aten KVM switch, but I'll have to troubleshoot that some other day. Heh, could be because I didn't have the usb drivers installed. The usb mouse did work on that computer though. FIXED after installing USB drivers!

As the temps weren't great when in bios (80+ after a while, and bios warning me of high cpu temp), and I don't know how to adjust away the 20 deg C offset set by AMD previously, I felt like removing the cooler and have a look.



This isn't what I expected. The cooler seem to touch the cpu heatspreader left of center, the opposite of what I expected. I guess I can reseat the cpu and make sure I put my finger on the right side.

Also, I used the credit card method of applying TIM, however I can't tell if I used too little, as it seems that the cooler did have good contact with the cpu heatspreader. I will use more TIM the next time.

Seems I have to figure out how to make the cooler be more centered. I did previously tighten the screws as good as I dared.


Update: I cleaned up the cpu heatspreader, and I reseated the cpu itself, and it sort of feels like the cpu sits unevenly in the socket, becuase if I press with a finger on either side, the cpu itself seem to wobble a little bit. So, I think I remember when I used the fastening clasp the first time, I had my finger on the cpu, and this time I'll just keep my fingers away and hopefully the cpu will sit as good in there as it ever could.

When I pulled the clasp lever back to release the cpu, the entire frame for the clasp mechanism appeared to move(!) and there was a loud "clack". That looked and sounded scary.

Here's the new amount of TIM for a re-seating of the cooler. I scraped off a little at the ends. Notice how the TIM goes along the line of the logo, which is also the alignment of the two clusters of cores underneath.



If this goes well, I might try another reseating with the credit card method, and less TIM.

Youre usong way too much. On my waterblock and 1700x i used a tiny drop in the middle and mounted my block.

Remember for tim less is better. It works better that way.

Ok, but, first, how do I counter adjust for AMD's +20 deg C temperature reading, as per their blog post from some weeks ago?`

If I don't adjust this back, the bios thinks my cpu is overheating, giving me a message about it.

Anyone?

You have an 1800x and with the latest bios update the temps read right. If they dont you can disable miskew and it should read right then.

My 1700x has read temps right on my ch6 since the day i got it.

What bios version are you referring to?

I'll try disable sense skew and see if the temps change.

I can report that disabling "sense skew" had no apparent effect, with the temperature reading looking the same as it did. (reminder: I use bios 1002 atm)

Btw, in bios, I can see the core voltage being reported as being values around: 1.351v & 1.417v. Cpu reported as running at 3.6GHz (iirc)

So far, I have not even touched any of voltage settings in bios.

Whats your idle temp?

So to try answer your question, the previous idle temp in bios was reaching 80+ deg C.

Looking at the first page in the overclocking thread, there's a tip for dealing with the temps, and so I re-enabled the "sense skew" and I set the value to 272 (previously set to "auto"):
http://www.overclock.net/t/1624603/rog-crosshair-vi-overclocking-thread

I also reseated the cooler, using less TIM, applying the time like I did the first time, with the "credit card" method. Given how weird it is to apply the noctua TIM this way, I think I am tempted to try that new TIM with liquid metal, if only to get to apply the TIM more easily (note, can't be used on aluminium surfaces I am reading on ThermalGrizzly's website). Edit: Name of this product is "Conductonaut"

So.. after enabling "sense skew" and setting the value to 272, I appear to have normal looking temps in bios, and in Windows.

These are the temps reported by HWinfo64, after a few minutes of staying in Windows 10 (only used for gaming).

CPU STATUS = 1.550 VID (?) (Heh, isn't 1.550 VID very high?, does this mean I have the most terribly binned 1800x???)

The following were the temps with an open case (panels taken off):
Cpu speed = about 3.7 GHz on all eight cores
CPU (TCtl) = max 51 deg C
CPU (Tdie) = max 27 deg C
CPU corevolt = 1.5 max (fluctuated between 1.381v, 1.494v, 1.285v)
Mobo temp = max 30 deg C
CPU socket = max 44 deg C
DIMM temp = 36 & 38 deg C
M.2 SSD temp = max 34 deg C
GPU core idle = 40-42 deg C
GPU VRM idle = 46 deg C
