Suggested cooling for the 5900x?

Rom · 17 Oct 2020 at 23:12

If im honest, my CLC280 is probably on par with my DH14. I dont think Ive lost much temp wise.
But it looks a million times better!

I have an Antec 900 case, 200mm top fan, two 120mm front, one 120mm rear. Plenty of airflow.
Can't think why I wouldn't use a Scythe Mugen 5 rev.b?

I've got an old coolmaster 212 hyper in my nearly dead machine. Could I move the fan from this to, say, a 212 Evo?

Would need the new cooler because I can't find a coolmaster mounting kit - and I'm not risking a second party kit not fitting perfectly and breaking something?

Or is the 212 series just sub par nowadays, and I should just stop skimping?

Is your other hardware expensive? Balance the cooling with the costs of your system. This time I built a fairly expensive PC so I forked out more for the cooling. Same with PSU, I find a little more in the right places goes a long way.

I'm trying to go cheap on replacables. Then buy more/better memory, cooling, pcie4 storage etc over the next 5 years, as I feel the need.

Feel the desperate need for an upgrade? I've got an option. If I never get around to it, what's the harm? Lose 1-3fps by not doubling my costs on CPU cooling?

i have a 2700x, check for thermal throttling / max boost, got a two fan aio and will never go back. e.g. 4350 MHz never thermally throttles at 100% cpu usage...

I could have sworn I said I was going to replace the oringal fans first to 4 PIN PWM (and yes I have already decided what ones I'm getting).

Anyway, could always go for something like this: https://www.tomshardware.com/uk/new...00-cpus-are-getting-threadripper-style-cooler

The Arctic 360 should be an option. Tried one and really liked. The issue was the GPU fans. Went full custom, 7x more money, but watercooling has been, for me, 50% performance, 50% hobby.

I'm plannng on building a new PC around a 5900x / RTX 30xx when, or if!, the stock situation stabilizes and wondered how you guys were getting on with your cooling setups?

I'm tempted to try and stay away from an AIO just for the simplicity/longevity as on my last AIO I found the pump buzz quite irritating but newer models may be better admittedly! No plans to overclock either if that makes a difference.

Any insight would be appreciated

i've had two aio coolers ARCTIC Liquid Freezer II 360 & H100i V2 240 mm and they are very quiet (pump blocks) radiator up top... modern cpus if cool oc themselves....

Cyber-Mav · 12 Apr 2021 at 08:15

I dont get it, these CPUs are rated at 105w my overclocked 1700 according to hwinfo pulls 110w and i use an arctic freezer 34 co which cost 20 quid and keeps cpu around 61c max in linpack with around 800rpms on the fan.
So wouldn't a 5900 or 5950 running at stock do similar temps and only put out the heat when overclocking?

I find it difficult to run stock as pbo etc is so simple.
Its if you want to run 100% for extended periods of time without throttling then you will want more. esp if using pbo etc

Cyber-Mav · 12 Apr 2021 at 10:38

whats the clocks the cpu runs at with pbo disabled? also what sort of temps does it get to?

My biggest cooling imorovement came by my putting in a side-fan, drawing hot air directly out of the case at the point where the GPU exhausts. This dropped my air cooled (dark rock pro 4 5900x temps by 5 degress. However, it's still running hot at 70 degrees all cores 100% mining xMonero to test it.

Edit for full disclosure: 70 degress was with the window open to the room too. With closed windows, the CPU is up at 78 degress when mining, stock speeds, PBO on.

tommoT.Striker · 13 Apr 2021 at 18:52

I think 70 degrees for 12 cores of Zen 3 running monero is a pretty good temp.

The issue with that is that I love the aesthetics of windowed glass side panels on my PC case so couldn't bring myself to buy a pc without one which could take a side-fan next to the GPU!

True enough. Maybe these windowed cases need to come with some discretly cut venting holes (get your De-Walt out !)

Actually I think it's time GPU cards came with optional exhaust pipes that could click over the heat oulet and enable piping of hot air to a rear egress slot. Like a blower, but we could choose to use it or not. There's a market for that, I reckon.

I agree. Thinking about it given the size,weight, power draw and heat generated by modern GPU's there's definitely a argument for redesigning motherboard layouts and cases around them IMO.

If the 5900x is anything as hot as the 3900, you'll need to run it under 280mm/360mm AIO if you want any kind of all core overclock/high boosts.

I've tried NHD15 and it was just about barely managing, a cheap cooler will work fine with games but if you're doing any sort of 100% constant workload (encoding, compute etc) it will throttle the performance by a lot. I assume anyone buying 5900x has a use for all of the cores, if not, a 5600x is the smarter choice.

It's not a small difference either, we're talking about being able to hold 500-700mhz more all core OC.

My 3900 can do 4.25ghz all core oc under water, still gets up to 75c 100% load. D15 was struggling to hold 3.9ghz and temps were getting to 90c. I can't imagine a cheap cooler being able to hold it higher than 3.5ghz before roasting the chip.

Thanks for the advice and suggestions. I don't actually have a specific use or need right now for a 12 core CPU. Initially I was planning on getting a 5600x/5800x and noticed that it's only an extra £100-200 over them for the 5900x.

Given the increased performance that seemed like a pretty reasonable deal especially in the context of buying a complete new PC for around £2000 which was what I'd budgeted.
