3950x temps

Go to solution Solved by Lordofcheez,

Yeah, don't do that. 

 

Use the Offset Mode, and do a -0.05V negative offset on the Vcore. You could go lower after that, but that's just to start.

First though, use the Auto voltage, run something like Cinebench R20, and note down your temperature, Vcore voltage and CB score. Then undervolt, and check those again. You don't want your performance score to drop (at least not too much), but you'll want to see those thermals go down.

okay heard that Ill try that later considering I dont want to spend another hour testing everything again.

Hi, I have had my 3950x for awhile now and I have always had a problem with the temps. When I leave everything at auto the max it gets is 85c. When I drop the voltages to 1.3v in the same tests (cine and blender) it reaches 100c. The case I am using it the nzxt h500i and the cooler is a noctua dh-d15 with only one fan. Im hoping someone could explain how I can get better temps. I have replaced the thermal and mounting it to the cpu twice now so im sure its not that.

Take off the front panel and retest your temps. Odds are your case isn't allowing your system the airflow it needs to keep everything cool. 

 

That second fan also does help a lot but given your case you probably cant fit it.

that's the normal operating temp of that cpu under that cooler, in that airflow restrictive case

undervolting, got my 3900x to 66c from 77c at stock, running 1.1v now

 

i kept my cores at around 3.95ghz at 1.1v, which is similar to stock all core boost clock at 1.25v

wattage dropped from 140W to 110W, temp from 77c to 66c, CB score about the same

Things I need help with:

Spoiler

none atm

 

I hate Intel's pricing, Ryzen's weird quirks, Nvidia's pricing, and Radeon GPUs in general

 

Spoiler

 

Products I like:

Spoiler

Sony Xperia Z1 / Z2 / 10 ii, Asus Strix 970 / 1070, Samsung SSD, WD HDD, Corsair PSUs (AX, RM, CX(grey)), GeForce GPU, NZXT N450/S340, be quiet! Coolers, G.Skill Trident RAM, Logitech M525, Logitech G440, Razer Deathadder Elite

 

Products I hate:

Spoiler

Xperia Z3, XiaoMi 5c, Radeon GPUs, Razer Audio Products, any bloatwares

 

Companies I absolutely adore: (and hope it stays that way)

Spoiler

be quiet! - sent me AM4 mounting for my DRP3 even though it's way past the timeframe stated, no questions asked

Corsair - very good RMA experience, absolutely recommend

 

Companies I hate:

Spoiler

Nvidia, Intel, Apple, TMT (Thundermatch, a retailer)

 

Personal Blacklisted Companies:

Spoiler

Acer: shit tier quality products, shit tier customer service thus far, they "tried" to solve my issue but they arent really doing anything but delaying and delaying. (on-going case since July)

Gigabyte: horrible customer service (gigabyte had literally 0 customer service, asked me to go to retailer with NO WAY to email them about a question) but at least they fixed my shit in ONE MONTH (would probably take me 1 hour to fix if they let me email them)

XiaoMi Phones: built like a tank but the software is buggy as all hell

Seagate HDD: had too many dead seagate drives

Kingston SSD: 300V controller swap thingy

Razer (except their mouse)

 

Remember, just because I had good/bad experiences with these companies/product, doesn't mean you will have similar experiences too. I would still recommend these products if they made sense for your needs, but I'll add a disclaimer of my experience if it's relevant. Feel free to DM me asking why they are where they are.

Hi,

Ambient temps? and you could try removing the side panel and check temps as said above, if that drops down the temps significantly then it's likely bad airflow in the case.

What do you mean you "drop the voltage to 1.3V"? The stock all-core voltage should be lower than that.

yes the side panel does drop it a lot should I just get a better case?

okay ill try a 1.1 do you think I can at least have the ratio to 42?

It drops about 15-20c when everything is stock and the side panel is off the max it gets is 68c at 3.9ghz

Oh I thought this was the glass front panel Elite version. My bad. Tofu's suggestion of the side panel as a test to alleviate any airflow bottleneck will also suffice.

No it is def airflow bottle necked I know that it was just weird that I was getting higher temps when putting it at a lower voltage. With the offset tho and not manually doing it seems to be working just fine.

tough, i got to 4.0 with my best CCD, 4.2 is much harder to get to, probably need a super good die

 

edit: yea it's basically near impossible on 1.1v
