5950x Temp concern!!

wookiee87 said:
i ran a auto cpu ratio but kept my vots locked to 1.275v last night and saw around 4-4.2ghz in most work loads, temps were amazingly low under 50 degrees but compared to my overclock of 4.7ghz all core i was loosing out (in games) plus temps when at 4.7ghz wernt all that bad, i've tinkerd a fair bit with my 5950x and i can say anything above 1.35v with high core speed will result in massive temps regardless of what cooling you run, if you want the best you have to drop the voltage and manage the clocks, why run at the ragged edge and have temps above 90 when you could back down a bit and save the chip, the hotter ryzen gets the more degredation the silicone suffers, upto 80 degrees is fine but anymore is time to tinker to bring down temps, undervolting is key

Ok. I have never had a CPU fail and I have had dozens some overclocked and overvolted to quite extreme levels. Ryzen running for all cores in the 1.3X volts range is nothing. It is also unlikely even with PBO that all core voltages go above 1.35V. Whilst I have a 5900X instead, it goes nowhere near that with PBO limits lifted very high.

Also up to 90C is fine according to AMD for the 5950X and PBO will deliberately boost up to that point. What science have you used to say 80C is too much?
 
Ok update ---- So i turned as much as i caould find in the bios to do with PBO off and i also remembered that when i upgraded 5 years ago to an 8 pack upgrade system the rad they sent was essentiall diagnol to the point it doesnt fit the case 100% however i remembered that i had it as they sent out a rma replacement. (Good Ole OC)

10 minutes later old(New) radiator and Pump installed.
Load under 10 minute cinebench run

well it certainly hasnt hit the 90's which it was doing. So max temp on CCD1 88c
Tctl/Tdie 82.4c Max. Much more respectable

Stil not 100% or optimal but it will do for now until i can get the budget for new case and cooler.

Thanks all for your help. Appreciated. Will update if it starts to creep

That's good as Cinebench run is actually quite intensive even if it isn't strictly the worst. If you wanted to test with PBO off, it should be off by default. Therefore if you reset the BIOS to defaults it will do that.

You can confirm that by looking at the maximum package power in hwinfo. It should not go above ~142W unless PBO is on. So you could use that to check if it is already off.

As long as temps remain below 90C, I wouldn't worry about it.

What PBO does is raise the PPT, EDC and TDC limits. I forget what the stock TDC and EDC limits are, but for PPT it is 142W. You can see below my PPT limit is well above that.

@thesword22 for reference, about 80c, i'm quite happy with that, if people are telling you 80c+ is bad they are being silly, they are designed to run at up to 90c long term, which is not that hot for a CPU and i don't know what they would be comparing it to but other CPU's run at these sort of temps and higher, and yet no one seems to be worried about that.

I'd say it's either the cooler/paste not seated correctly or the cooler it's self on them temps you are getting.

Run a 5950x myself with PBO and run around in the mid 60's in star citizen with a GPU,Chipset and VRMs in the loop as well .

Star citizen is completely different to Cinebench. One is an AVX CPU load and the other is a game.
 
I mean that isn't how 99% of posts work (Go through threads and see how many posts without quotes refer to the OP and aren't simply a continuation if the conversation.), but not something I'm going to argue over.

Wait am I now referring to the OP?
 
Right Update 2 - So last night i played Star citizen for roughly 2 hours or so (before thinking my luck would run out and i would die) Temps were roughly averaging 84-85c with a max CCD 2 of 95.3 and max CPU tctl/tdie of 92.1
So i thought to myself - Case aesthetics are not everything - since the case is under my desk anyway.

This morning i have moved the Radiator to the top of the Case with the Fans above it in exhausts mode - Lid of the case wont fit but meh, i can live with that for now.

10 minute Cinebench test done and the max Tctl/Tdie temp was 69.6c. Wowsers thats come down a lot from last nights 88.4c

Still to try Star Citizen out but cant do that while working. Will do that this evening.

I think its because the rad is pipes up.

Mr Humbug currently you are correct. What a difference it seems to make.

Yeah, water always rises to the top, and all radiators, even brand new ones have some air in them, so if you have the pipes at the top you're circulating that air around the system, air does nothing to cool the CPU if that's what running over the cold plate, and the older the AIO is the more air is in it.

Pipes down there is no air, all the air goes to the top of the rad, so the pump is circulating nothing but water, effective cooling.

70c in cinebench is good, and yes its a huge difference from what you were getting before. glad its worked out :)

Must be, you didn't quote anyone else ;)
 
So been playing Star Citizen for quite a bit over the last few days and temps have not gone above 80c across the board.

So i would say problem solved. Thanks all for your replies and help. I guess orientation does matter lol efveryday is a schoolday
 
humbug said:
Are you able to turn the radiator round so the pipes are at the bottom? Or mount it to the top of the case?

The the problem with the pipes being at the top of the radiator is there is air inside them, especially if its 5 years old, if that air is being pushed round the system, which it likely is, it will your CPU's temps will suffer, there could even be an airlock in the pump.

Let's Talk About AIO Orientation... Again

Someone had to say it. This issue is being blown way out of proportion. Here's why.SPONSOR: Thermal Grizzly's Carbonaut pads are an excellent substitute for ...

Somewhat blown out of proportion as most people's setups will be fine as long as the pump is lower than the radiator. Air trapped/locked in the pump is the biggest issue.

Glad you got things sorted OP. Everyone should remember that when a 5950x runs hottest it's likely under single core load during something like gaming. All the heat is focused on one core boosting as high as it can on a 2 CCD chip. This is why even idle can be spikey with these chips.

But hitting the 90s isn't good.
