3800x

[Xbl]

Finally upgraded my 2700 to a 3800x. And what a improvement in games. On average about 10-15fps more only concern is the temps whilst using a Corsair h100i platinum.

Getting about 70 whilst gaming and around 81 when stress testing. Although it's well under the recommended max of 95 I'd feel happy if it was around 70 on a stress test as well.

Granted I'm not gonna be doing anything that's gonna max my CPU out 100% 24/7 but you gotta account for a bit of dust build up in rads etc.

Only clean my pc once every 12-18months (normally when I buy something new to go in it)

Heat density issue is to blame, but also high stock voltage. Give it some negative offset on the voltage. Make sure you dont do too much to the point where scores drop though

I have the same on my 3800x, PBO enabled, on a 240mm AIO. It's completely normal. In some testing I did, I kept the clock speed (3.9GHz), PBO Disabled, except i dropped the voltage from whatever auto is, to 1.2V, and my temps in Cinebench R20 went from 73, to 56C. Granted my score dropped a few hundred. 

 

Once I get my ram tuned more than it already is, I might mess with things and see if I can keep stock speed + PBO (which seems to be better than overclocking), but d ropping the voltage a bit to drop the temp.

Same for me on Kraken x52.

I would really recommend undervolting. The motherboard will try to push some stupid voltages like 1.4, when in reality you will need ~1.3 or even much less. My stock 3900 was running 1.4vcore stock, and maxed out at 75°c with a monoblock! I was able to drop that down to 1.28 somthing and sits at 52c full load with an oc.

Hi !

I have a similar issue here.

My 3800X is running... Well, at like 45°C at full load :

 

And sometime... It goes way higher on the same test !! Like at 80°C I don't understand why.

 

I did the test again today (OCCT : MDS) :

 

Same temps... Odd... And the Voltage seems very low to me but doesn't go lower at idle... I feel like all of this is very wierd. What do you thnik about all of that ?

Rule of thumb: the problem many times, that the cpu is not as good as transfering heat to the heatsink. Lot of people complained about hot running CPU, while the heatsink was cool to touch.. It's a characteristic of 3rd gen, it seems.
