Recently bought a 5900x to futureproof my system for gaming and work. Before this I had a 3700x, using the same cooler. Scythe Mugen PCGH edition. It cooled my 3700x without problem. But now with the 5900x, at some games it reaches higher than 85 degrees. Idle temps are around 38-48. Especially Call of Duty Cold war and Far Cry New Dawn. New Dawn is really bad as it goes to a steady 85 spiking to 88. Other games, like Assassins creed Valhalla runs around high 60s low 70s.

I am at a loss what to do, as I'm not experiencing any fps dips because of the CPU and I read some conflicting reports. Some people are saying that 90 degrees should be fine for the 5900x, but I see other people going max 80 and I would feel more comfortable with those tempratures. Is it time to swap in a new cooler? As it is a relatively cheap air cooler.
Would love to hear your suggestions as I'm not sure what to do and I don't want to return this beast of a cpu.

You could always replace the 800 rpm fams on your cooler with some beefier ones and change the cooler from an ultra low noise one to a higher performance one.

Thanks for the answer, makes big sense now. I wondered why my cpu fans barely hit 800+ rpm. Now I know. Next step will be replacing this air cooler with a better air cooler. Any suggestions for a killer air cooler that pairs up with the 5900x?
 
You are only talking about temps but not performance, you could look into bios and see if it has PBO enabled, if you disable that you should get cooler and probably won't loose enough performance to even notice, if you do notice it's one reboot to change it back.
Your bios could also have a setting for which temp to reach before clocking down so that's another one you could check.

The 5900x pulls almost double the watts of the 3700x so yes better cooling.

There is a significant TDP draw difference between the 3700x and 5900x. (65W for 3700x and 105W for 5900x)

The 5900x will run hot under load and a Scythe Mugen is inadequate for anything above stock frequency. No Air cooler will cope under load with the 5900x for extended periods.

You should get an AIO water cooler of H110I or equivalent if it will fit
your case.

You can reduce your heat output by disabling boost frequency and have an all core synchronized overclock. You can also try reducing Core voltage as Ryzen Bios can be set too high. No more than 1.375V.
For longevity keep your max temp around 80C as 90C is too high.

Buying best when it got wind without new wind, when it didn't work well there, it worked well to gain efficiency, already carrying out efficiency.

Those are very nice temps.

Yeah, I'm wanting to avoid liquid cooling though. More moving parts and just my preference, but I prefer a fat heatsink with big fans. This thing is quiet, I'd like to keep it.
This is my first experience with liquid cooling.
I couldnt fit the air cooler I wanted in the tiny case and found that this liquid cooler is virtually silent when you use the app and set it up.
It can ramp up well while gaming, but Im glad its keeping it cool so the sound doesnt bother me and cant be heard over the game anyway

You can't go wrong with decent liquid cooling, the Kraken line is well established as decent liquid cooling. I also like how sleek they look in a case. But then I also like how 'industrial' an air cooler looks! This is mine:




Bottom line is as long as it keeps your set up cool, either choice is a good one if you go for decent quality parts like you and I have, and as the OP has also chosen to do. Be interesting to hear how the OP gets on, that 360 AIO is a nice model.

That looks great!
If I have time tomorrow Ill blow the dust out of the Kraken cooled PC and take a pic.

Allright I got to installing the 360 AIO yesterday.

It wasn't easy with the NZXT H700i case. I had to remove the three front intake fans, and install them in the top area of the case were I wanted to fit in the AIO, but it didn't fit because of the motherboard (Asus prime-x570 Pro). The combination of the NZXT h700i, Asus prime-x570 pro and the arctic freezer II 360 AIO only fits if you install the AIO in place of the three front fans. I'd also advice at least one other pair of hands to get this done.

When it was done I got to testing. Idle temps at first where almost identical. 30-40 degrees. Wasn't a promising start. After checking the games that run most intensive on my system, I found out that the Far Cry spiked to 88 instead of 91,6 (with my other cooler 91,6 was the highest). Call of duty spiked to 86.

So it seems to be a case of the wrong case. The H700i is a medium sized case in which I have a rtx 3080ti, which does fit but not by a large margin. That one is already hot and was blasting hot air into the air cooler I had.
Decided to take off the front panel of the case, giving the radiator of the AIO the space to breathe. It seems that this is what has done the trick, as my idle tempratures are now high 20s-30 (coolest they have been), Far Cry spiked around 79-80.

It's a bad case, the air cooler was doing a good job compared with the AIO, only three degrees cooler with the front panel on. I will probably change cases when it gets hot this summer.

I will be doing some more testing this week when I have the time. I didn't test out call of duty yet without the front panel off, but I expect to see the same drops in temps as with Far Cry.

Yeah, if you remove case panels and temps drop, that's a sure sign that your case airflow needs looking at. The 3080ti is one hot graphics card though, so it's always going to be challenging to keep everything else cool.

That case got a good review on Gamers Nexus a few years ago though, how are your case fans configured?

I'm putting together a system now. I guarantee it is not going to look anything like yours.
Nice Job!!

I moved the three front intake fans to the top of the case, theyre blowing from top to down now. I have one fan on the backside of the case blowing air out. That's the airflow at the moment. The AIO fans are in place where the original intake fans used to be, in front of the case taking air in. I removed the front panel and it worked wonders on my temps. All around 10 degrees lower temps than with the air cooler. It's still a hot chip!

It's a pain in the neck to install a water cooling system. After 2 years in computer service, I have to say 90 is fine. You should try it to download OCCT software and try your PC and you will see what the temperatures at CPU, Graphics card at 100% usage

And now one could wonder, What would the temps looks for the original air cooler with a slightly faster fan and without the front panel?

That's actually the best place for your AIO fans, in the front drawing in cool air. If Steve from Gamers Nexus is to be believed, and I reckon he certainly knows quite a bit about this sorta thing, having it that way means that the pump will stay lubricated with coolant and is the optimal set up.

You might want to experiment with having the top fans exhausting air from the case though, worth a go to see if temps improve further. I have 4 intakes and 5 exhausts and it works ok.

But seems like you've nailed it sufficiently for temps to be safe and workable.

There's around a 4-5 degrees difference between front panel on and off, plus the spikes are lower. If I had taken the front panel off before with the air cooler, I probably wouldn't have made these posts as the temps would have been acceptable enough. Ah well, it's all a learning process..
The system does look way better now, imo. I also like the occasional watery sound coming from the tubes. Plus I am (or might be) summerproof now.

That's a great tip. For now I am fine with the temps, when summer comes around I'll try it out.
