New CPU installed, running too hot ?

I've installed a new CPU, GPU and memory and now my CPU temps are a fair bit higher.

I had :

- Gigabyte X570 AORUS ELITE
- AMD RYZEN 7 3700X EIGHT CORE 4.4GHZ
- Gigabyte GEFORCE RTX 2070 SUPER WINDFORCE OC
- Patriot Viper Steel 16GB (2x 8GB) 3600MHz DDR4 C17

I've kept the mainboard, but replaced the CPU, GPU and the memory and bought :

- AMD Ryzen 7 5800X3D Cache Eight Core 4.5GHz
- Corsair Vengeance LPX Black 32GB (2x16GB) 3600 MHz DDR4
- Sapphire Radeon RX 7900 XT Pulse 20GB GDDR6 PCI-Express

I've got a 'Cooler master hyper 212 RGB' CPU cooler, and a fair amount of fans (2 on the top, 1 side window, 1 front, 1 on the bottom and one on the back panel.

Before the new install, if I looked in the BIOS on start up it showed :

CPU temp: 26.0 C
System temp : 21.0 C
PCH: 29.0 C (not sure what this is...)
VRM MOS: 21.0 C

Though after new components it is :

CPU temp: 42.0 C
System temp : 36.0 C
PCH: 51.0 C
VRM MOS: 36.0 C

I've got that 'core temp' app running the back ground now and CPU temp is sitting between 38 - 44 C, and during installation of some items (office etc) it went up to about 68 - 71 C.

I've just ran a game for a few minutes (Hogwarts) and the max temp was 90.0 C.

Am I right in thinking these temps should be way lower, or is this normal for this CPU ?
 
They're not dangerous or anything, but a little toasty, yes. The Hyper 212 is an extremely basic and slightly outdated cooler by today's standards. You don't need to spend a fortune to find something much better, like the Thermalright Peerless Assassin which is around £40.


Alternatively, just look into using Curve Optimiser in your BIOS. There are lots of guides around on how to set it up for the 5800X3D and it should help your temperatures.

Cheers, that's one less worry.

Just out of curiosity, from what temperature (idle, and gaming) should I start to get worried and look at replacing my cpu cooler ?

5800X3D is good up to 90c before it'll throttle anything under that is fine. Granted your current cooler is on the lower end of the scale for performance which is potentially why you've hit that whilst gaming (current heat in the UK doesn't help)

it throttles before 90c I found my 5800x3d starts to reduce clock speeds from 4450 when it reaches around 79-80c guess thats when its throttling but thats extreme stress testing, gaming its much lower and keeps the 4450 clock with 360 AIO 50c-70c depending on the game using -30 all core

Cooler master hyper 212 is not the best and RX 7900 XT Pulse will also be dumping more heat into case

I would change it to the peerless assassin
Yeah these new chips boost hard
And get hot
But that seems too hot for gaming
Where you're really not using all the cores
You could also play with curve optimiser
And try to get same speed at lower voltage and heat
Though that's time consuming
 
Guess a new cpu cooler it is then.

Am I right in saying that when I remove this one and look at my (new) cpu the thermal paste should be covering most of the surface evenly (after putting a little blob and an X of paste on it) ?

Also, my psu is a corsair RM750X, could that cause any heat issues if its not powerful enough, or more really?

Full coverage of the area where the IHS and cooler coldplate meet is ideal, yes. You'll find lots of strong and differing opinions on the exact method you should use to apply it, but it really doesn't matter so long as you use enough. Spreading it out yourself or letting the cooler do it when you seat it will be fine either way. At worst you'll make a bit of a mess, assuming you're not using an old tube of Arctic Silver or something that's electrically conductive.

As for the PSU, no, it shouldn't affect anything. That's a perfectly fine unit for your setup.
 
fair amount of fans (2 on the top, 1 side window, 1 front, 1 on the bottom and one on the back panel.

Is this a good fan config for ur case or could it be more optimised? I see a lot of pics these days with fans covering all sides of a case with flashing rgb and i think that doesnt look like its gona flow in and out of the case quickly its just gona cycle air all over inside with diff temps of air depending on how many are in and out. I thought it was best practice to have one or two in and one or two out and then u get a nice flow and direction stable course of air flowing through. Thats why im wondering if maybe just have 2 on the front intake and one on the rear and one near the rear but top it might help streamline a jet of air. Tho i could be talking balls and it doesnt matter lol. Just thought might help drop a degree or two if u wanted to try it.

The cooler might be a bit old and low tdp rated for the x3d chip, somit for the range of 40 quid might be better, u could probs flog ur old cooler for a few quid to help towards the new one.

Edit - plus were into summer and the heat is rising, im already needing ice packs to keep me cool now, let alone what a hot cpu will be like, im dreading turning my new pc on im building and almost ready to just needing to swap gpu from old to new but i cba to quite yet lol. But thats a 7600x and i just picked a cooler i thought might do but kinda wish i got a little better one now but oh well its on. I got the ak400 zero dark plus cooler for it, says 220w tdp so figured should do ok, not like im doing anything like cinebench all day ever day is it lol, im hoping gaming wont hit too high more than 80c (hoping tho really no more than 70), and idle or watching stuff on twitch which i do most days it probs hang around 30-40 range.

Yes it is running a little too hot, you really want low to mid 70c range MAX when gaming, 90c is pushing the chip a little too much i think as im sure it starts to throttle around that temp.
 
Sorry ive not read the whole thread so I dont know if this has been mentioned, but go into your bios and set the curve optimizer to -30 for all cores, most 5800X3D will do this, you'll notice a big difference in temps straight away, if you start getting crashes or BSOD's dial it back to -25, then -20 etc etc, 5800X were known to run hot, 5800X3D is even worse.

Regarding case fans, defo sounds worth checking the airflow, as a quick test just take the side panel off for a bit and see what difference it makes. If it's a massive difference maybe you also have a case airflow problem.

When stress testing the 5800x3d I notice the clocks start dropping once it hits 80c+

Gaming load shouldn't be as high and he is hitting 90c that's way to high imo

360 aio with 9 120m fans fully stressed tops out at around 82c

Gaming with 3080 depending on game 50c-70c mostly would say stays in the 60s

And yeah peerless assassin is the new hyper 212

I have ordered a 'peerless assassin 120 se argb' to replace my hyper 212. Once fitted I'll report back with the temp differences.

It's a large case that came with those fans fitted anyway so it's the design of the case and not just me adding fans everywhere :D

I must admit I've never even heard of curve optimizer so no idea what this is or does, but happy to give it a go once the new cooler is in so see if it makes any more difference.

Curve Optimizer
Basically you try to get same speed
But using less voltage so create less heat
Can be time consuming
As sometimes it seems stable gaming and stress testing
But may crash or blue screen doing light things
You can either let it try to automatically set it for you
Or input a manual value
But yeah see what temps are first with new cooler
You might not need to play around with curve Optimizer

negative curve optimizer = less voltage to the cores = less heat generated.

positive curve optimizer = more voltage to the cores = more heat

Its easy to set up on a 5800X3D, like I said most of them do (negative) -30 which is the max, this reduced temps on mine by 15-20oC, you can either do it in the bios or you can use this piece of software to try it first which makes it dead easy to set up, make sure its stable and then copy the settings to the bios and get rid of the software, everyone with a X3D chip was using this software before they finally decided to add Curve Optimizer into the bios, its called PBO2 Tuner: https://github.com/PrimeO7/How-to-u...X3D-Guide-with-PBO2-Tuner/blob/main/README.md You only need to go as far as step 5, dont worry about 6, 7 etc onwards, just means you'll have to launch the software yourself after each startup until you put the settings into your bios, or you can continue to use the software and follow step 6 to get it to auto launch on every system startup
