New CPU installed, running too hot ?

[Medic-one]

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 ?

The 5800X3D will run hotter than the 3700X you had previously.

Those temps are nothing to worry about.

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 ?

 

[Medic-one]

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?

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.

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?

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

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.

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.

I'm stuck trying to install this peerless assassin cooler.

I've removed my hyper 212 and the backplate it came with, but I believe I need to original backplate now to install this new cooler, which I can't find anywhere.

I've had a look on amazon and have seen some "amd 4 backplates" on there, are these all universal fit or are they mainboard specific?

 

[Medic-one]

Not sure what MM is, but I've found one in amazon which will be delivered tomorrow (prime).

Before the new install I had :

- Gigabyte X570 AORUS ELITE
- AMD RYZEN 7 3700X EIGHT CORE 4.4GHZ
- Cooler Master Hyper 212 CPU cooler.
- Gigabyte GEFORCE RTX 2070 SUPER WINDFORCE OC

And this is what it looked like temp wise in the bios :

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

The GPU is quite a beast in size and even sits a little bit over the mainboard fan :

And it then looked like this :

I then installed the latest motherboard AMD chipset drivers which made the system temp come down, but CPU temp whilst playing a game still came up to about 90° C.

As advised here I then replaced the 'Cooler Master Hyper 212' with the 'Peerless Assassin 120 se argb' and it now looks like this at the moment :

Doing stuff around windows CPU is sitting around 38 - 45° C and I just briefly ran that same game again (with Coretemp running on screen) and temps were sitting around 55 - 65° C, so that's definitely an improvement from before.


It did notice in the bios the 'CPU frequency' is sitting a bit lower with new CPU compared to the previous one but not sure if that's something I should worry about too much ?

Looking at the comments in here I guess these temps are normal/ok for this CPU, or should I still look at lowering them with this 'Curve Optimizer' app ?

Improving the case cooling would probably help. I added an RTX3080 to a system and under load it was cooking the system causing it to crash/shutdown. Adding another 4 high flow case fans has brought the temps down to more reasonable levels. Now the RTX3080 is just loud.

Don't think there's room for any more fans as it's already got 2 on the top, 1 on the front, 1 in the side window, one rear one, and one at the bottom...
