AMD Ryzen 5 & 7 CPU Cooler Round Up

[Daiyus]

You would not be able to remove the res. Not without draining the loop. Well, unless you use QDC and they are expensive. What you are better off doing is having a fill port. Then you don't need a res. To make a fill port you need to fit a 3 way T piece in front of the pump return (so the water can feed in and be pumped around) with a straight piece of tube coming up to a fill port so you can put the coolant in.

I am about to do this to my rig called Riff Tamson. Keep an eye on the log. I do have a res, but, it needs to be looped up in situ and the top cap is blocked by the res above. So I am going to fit a fill port so I can fill the res "remotely". However, there is no reason why it would not work in a "resless" loop. The only other thing to ponder is that the coolant expands when it is hot and shrinks when cool so you would need to fit some sort of relief valve. However, you could just screw that into the fill port's G 1/4.

Nice. Really good advice, thank you. I think I may just try and fit a 240mm AIO in for the time being though. The SilverStone Tundra TD02-Lite Seems like a good balance between size, price and cooling capability. It's black and white too which matches the theme.

While 70°C is considered a good temperature for an overclocked i5 or i7, it's worrying to know that even big air coolers struggle to keep these guys reigned in. Is 70°C a dangerous temperature for the CPU or is that limit applied for a similarly arbitrary reason like the offset? If it's dangerous for the CPU to reach 70°C then that's like hitting 90°C+ on an Intel CPU, which I personally would never go near. That's worrying. Makes you wonder why the offset was there. Maybe AMD had a reason for it.

That is the reason. To avoid hitting 70C

I never thought of it until now. It makes sense. It's frustrating really. Not the whole temperature offset but the fact that 70°C is a shut-off point and a 4Ghz overclock hits close to that on good air coolers.

 

[NeverBackDown]

That is why I was advocating for a higher ceiling for the next chip.

I do wonder though, if the CPU itself sees 70C as 90C. If it does, then that is an issue that cannot be fixed. If the CPU sees itself as 70C at 70C but the sensor just reports 90C, then I wonder if that could be fixed. But I suspect the former is the issue here. I don't really think Ryzens limit is this low. Considering silicon is capable of handling much more heat.

 

[AngryGoldfish]

Maybe the process is too early and untested for AMD to risk doing a Samsung.

 

[NeverBackDown]

That wouldn't be the issue. I think it was just an engineering decision for them. They probably knew it wouldn't clock as high and the volts required would be low enough to justify keeping the CPU below 70C to expand the lifespan. Who knows really.

Still haven't even tried to OC my 1500x compared to my 2500k it's just fine as is for my needs

You all now this is nonsense?

Ryzen has a thermal limit of 70 degrees, which means that when the CPU gets above that temperature the for more than a few moments the system will shut down in order to prevent damage to your processor.

This is incorrect, Ryzen throttles at 95 and is fine to run a gaming load 70 ish 24/7.

Take into account the fact that Ryzen has a thermal offset of 20 degrees and that a large number of motherboard throttle or shut down before the CPU hits its Tmax value.

In our Ryzen testing over a wide range of motherboards, we have found that any sustained thermal loads of over 70 degrees (90 degrees including offset) would result in a shutdown.

While some motherboard makers will allow you to get closer to 75/95, any well-designed board would keep you further away from this limit to prevent damage to your CPU as an additional "safety factor".

To say the least, while 75 degrees is the Tmax value for Ryzen, it is far from a "safe limit" as it will prematurely degrade your silicon.

Sitting that close to the limit would mean that your system is only one hot day away from the limit anyway, it is always best practice to say far away from any CPU's Tmax temps.

what about the phanteks air cooler that surpasses the corsair h100i. I do not like a ready water-cooling solution as you pay allot for a limited time of use. If we could refill them and change tubing's (replace their parts, instead of throwing them away when the liquid evaporates or the tubings get bad)... then yes... but there is not any. 120-180 euros is allot of money for what they offer.

The Phanteks doesn't really cool any better than other similar sized air coolers. The R1 Ultimate, Thermalright Le Grand Macho RT, Phanteks TC14PE, Noctua NH-D15, they all perform within margin of error of each other.

most enthusiasts would, but not everyone will. Especially those people buying the 1600/x CPUs. Either way, spending all that money on a cooler hurts the "cheaper" argument people, including me, would use. It'll still end up cheaper of course than an intel system, but still more money is still more money.

Not saying that I disagree with you, but a good AIO is like a good monitor. It will be there when you upgrade. Maybe one would add it latter if budget is an issue.

I'd like to toss in one point people rarely (if ever) mention when talking about AIOs versus air coolers. Unless the AIO is tested PROPERLY, it's not a valid comparison. By properly, I mean if you REALLY want to test the heat dissipation capability of an AIO, you need to stress test for MINIMUM 1 full hour, if not 2 hours. The good thing about air coolers is you'll hit your "worst case" scenario much quicker. With an AIO, you don't hit the "worst case" scenario until your liquid temps max out, which takes a while since liquid heats up a lot slower than air. Anyone who buys an AIO, stress tests for 20 minutes, and then assumes they're doing much better than an air cooler is incorrect, and not taking that stuff into account.

Top end air coolers ARE comparable to AIOs. Back in the day, when I first went from a good air cooler to an AIO, I gained NOTHING in terms of temps. But that wasn't obvious until I stress tested for hours.

I know this is common sense to some of you, but I thought it was worth mentioning.

I'm getting 59-60c using a gammax 400 using the same test. 3.9ghz @ 1.3125v

 

[NotoriousQ]

I would like to see how the u9s and the d9l would work.

Also would like to see the shadow rock lp and pure rock slim compared side by side with the u9s and d9l

As much as it would be nice to see more data in the tables, we are not going to redo the testing to repeat tests from over a year ago.

Perhaps we will do something like this again in the future, though TBH most of AMD's Ryzen 2nd Gen CPUs ship with great stock coolers and overclockability is pretty much not worth it on Ryzen 2nd Gen X-series SKUs.
