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.

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.

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

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.
