Old stuff: 5900X running a bit hot.

[OnlyMe]

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.

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 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

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.

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'...
