My current build is a socket 4 system, previously with a 3800X in it, with a corsair H80i v2 which is about 5 years old now. Its in an Antec p180 full tower case. Once upon a time state of the art... now, not so much. Anyway i fancied an upgrade and am too lazy to replace the MB, but could not get hold of a 5800X3D for sensible price, and could not take the reduction in clock speed of a 5700X3D (I know, I know :)) so i went for a 5900X for 200 quid. Same 105W TDP.

Temps before with the 3800x were about 50 - 70C, now with the 5900X its 60-90C. 75-80 when normal gaming, but prime95 for 10 mins and its hitting 90 and presumably throttling. I've applied a manual Curve Optimiser value of -10 to all cores (bloody auto thing said -30 to all and wouldn't boot!). Anyway I assume those temps are not normal and that old H80i just isn't cutting it, or its lost some coolant or somehow got worse over that last 5 years or when i did the CPU swap - is that possible/probable?

Cooling otherwise is pretty good, 2 filtered intakes at the front (one pushing air over the GPU), h80i rad with 2 fans intake on the back, and top fan pulling out, PSU has its own chamber.

I'm thinking about buying a peerless assassin or similar air cooler and seeing how that goes, but I think that would mean changing the cooler backplane and therefore removing the case from the MB - there is no cutout for access to the back of the MB in that old case. If I have to do that, then i might as well just upgrade everything. In fact, i might as well buy a whole new system in a new case, except that I'd want to reuse my RTX4080 which i was hoping should last a good 3 years at least. Anyone able to confirm the backplate change would be needed?

Or I just live with it till summer when it will doubtless overheat and buy a new system then :)

My 5900X wasn't a whole lot cooler with a 360 AIO. I never experienced throttling, but my gaming temps were similar to yours. That being said, my case ambient temp was relatively high because I wanted it to be as quiet as possible.

While I don't doubt you can get those temps down if you make changes, I wouldn't expect a night and day difference.

Thanks. Yes i should have said my cooler and fans are mostly set up for quietness over performance. Saying that, once the coolant temp gets to 40, the AIO fans are set to ramp up quickly to 100%@50C so it gets noisy fast. I could set the curve lower, but i like a quiet PC if i'm just web browsing etc.
 
I have a 7900X on a air cooler. I have put it in ECO mode at 65W as gaming performance was pretty close at when compared to 170W, the difference was in productivity by about 5-10%.. so no big deal for me.

I game under load averaging around mid 50's when my GPU is pegged out.

We're pretty much in the same boat then. You could spend a bunch to improve it a few degrees, but unless you want to take on extra noise, it's probably not worth it.

As you're noise conscious. I upgraded to a 9800X3D, I did a -30 all core curve. Under extreme stress testing, it stays at the max boost OC on all cores and barely hits 60c. It's dead silent under normal workloads and gaming. I could obviously OC the **** off it because it performs fantastic, but I'm happy with the all core 5.2Ghz and silence!

Very nice.

Just prime95 tested this setup again and am getting a steady 4.2 on all cores, at 90C, after running 5 mins! Coolant temp gets to 45 then fans seem to kick in and out to keep it there. But the CPU is 89-90C all the time :eek: Package temp gets to nearly 91... I know AMD say these chips can run 80-90 without problems, but it just feels far to hot to me. OTOH, it is a stress test, its not often i'm going to want all 12 cores running flat out for 10 mins.

A new system sounds good. I just can't be bothered anymore with the faf of moving everything over. Or the faf of a serious upgrade. I'm just too lazy. 20 years ago it would have been new motherboard, ram and processor now, then disks and graphics 6 months later :D

Is ECO mode available on 5000 series? Not heard of it before. I guess everything is a compromise between cool/quiet and hot/performance/Overclock and while my brain says 'FAST AS YOU CAN' another part of me says 'quiet'...

it was a performance mod, in the BIOS. I have a ASUS TUF motherboard.
 
Modern AIO come with offset mounting brackets for the Ryzen processors that really do help with temps. You could maybe see if there are any modded brackets for yours.

The next thing to lower temps would be mem/SOC voltage. If you have just enabled XMP I can guarantee it's pumping more voltage through the IO chip than needed. If I remember correctly I knocked a good 5 degrees off just lowering that on my 5900x

Don't know about offset brackets, quick google didn't find one for h80i and 5900x (theres not a lot on that CPU and that cooler combo tbh), but if i had to change the backplate that would be no good, might as well just get a new MB/Processor/RAM/SDD and be done :)

But i've not heard about RAM voltage increasing CPU die temps, except by ambient temp increases, certainly something to look at. My RAM does have an XMP setting, but (iirc) it never worked stably on my 3800X so i just set the timings/voltages manually as per the RAM 3600 spec. Didnt even look at it when swapping to the 5900x, Ryzen Master says 1800 clock, coupled mode on and CAS 16, that was enough for me :D

Thanks
 
Saw the thread title, predicted a gigabyte board. Was correct.

They can overpower the CPU by upwards of 20% by falsely reporting power draw to the boosting algorithm - this is on default settings.

You can test for this by checking power reporting deviation in HW info 64. If it's lower than 100% under load (I used Cinebench), it is unreporting power draw to boost higher but efficiency goes out the window.

My power reporting deviation is 115% apparently... erm how? Anyway i've sorted it I think. I'm too embarrassed to say how BUT package temp under 10 min Prime95 load is now 72C and around 4.4Ghz on all cores. Will see how it goes.

Come on! let us know what you did. You wont be the first to have done whatever it was you did

Well, i took the back fan and the rad out of the case, fans off, and cleaned all the dust out of the fins that had accumulated between the fan and the rad fins. It was pretty bad, 5 years worth. There's filters on the case intakes, but not on the rad intake fan which is pulling in.... I had cleaned the fans/rad with canned air a few times but obviously that didn't clear it.

Still after 3 hours gaming with the gpu also under load the package temp is getting to 85C, but coolant isnt getting much past 40 when the fans ramp up. So still not ideal, but much better than it was. Hottest CPU core at (mostly) idle now 49C and package 53, coolant 38. So if you are going to reuse an existing cooler, make sure you dismantle it and clean it first. I guess the old CPU had gradually got hotter as the dust accumulated, but I didnt really notice, plus I wasn't really watching temps before i put the new CPU in.
 
My 5950x is currently hitting around 75c on prime blend testing. All cores around 4.3ghz. My AIO is about 7 years old now and I haven't actually thought to clean between the rad fins. I'll definitely check that, cheers.

I'd be interested to hear the results. I've now replaced the old corsair fans on that h80i with arctic p12PMWs and also the old top outtake fan which was an old Antec tricool one. Now when it spins up (and it still does after a good hour of gaming), its much quieter. Couple of degrees off the temps too but at load it can still get to 75-80 pretty easily. Graphics card temp makes a big diff to the cpu temps if its running hot, probably that graphics card hot air exhast is going out the case and being pulled straight into the cpu rad! Oops, but nothing much I can do about it, except move the pc case to a more ventilated area which I probably will do before summer. I'm at the limit of this P180 case, so new case, new mb, new cpu, new ram, new cooler all needed, might as well buy a prebuild OCUK one and start again. I was hoping to skip AM5 but not sure if I'll make it :)
 
An h80 is only a 120mm radiator
That's possibly why
Though when you cleaned out the radiator fins
Did you replace the thermal paste?

Got a 5950x here
Am4 is still a great platform
I will definitely skip am5 quite easily
 
Yes ofc I replaced the thermal paste after i took the cooler to bits :)
Was worth asking just in case

A bigger aio may work better
Though no idea if could get another corsair aio
That's a bigger radiator but still uses same backplate
To make life easier

My 5950x doesn't come remotely close
To those temperatures
Though I have a custom loop so lot more radiators
Though also got a 3080ti dumping a load of
Heat in there
 
I cant fit a bigger rad into the case. The h80i is a double thickness rad, so slightly better than an ordinary 120mm. But still more then 7 years old now.... I have a 4080 in there too and as I say the exhaust from it is below the back fan mount which is where my rad is, configured as intake. So when the 4080 heats up, not only does the rest of the case start to get hot but the AIO intake will be pulling that hotter air back in... never mind, its working fine atm just can get hot. I suppose i could try mounting the rad in the top 120mm fan mount but I'm not sure it would fit and i cant be bothered with that atm
