Question Is a 240mm AIO suficient to cool a Ryzen 7 5800X3D or my Thermaltake Thoughliquid 240 Ultra came malfunctioning?

[UeharaXG]

Just assembled the AIO and right from beggining it is performing much worst than my previous Ryzen 5 5600X with an original air cooler (I guess it a Wrath).

Iddling at 71C/159.8F. Liquid temp at 57C/134.6F

Easily goes up to 90C/194F and stops there because of throtling, I guess.
Fans and pump manualy set to max RPM.

Do I just got lucky an got I bad AIO or a 240mm is not sufficient to cool down an 5800X3D?

If it is the first case I just have to by a new one: this one I receveid from my uncle in USA, I 'm living in Japan and just don't have the invoice to claim an RMA.

IF I need a 360mm AIO I'm also in bad luck: there is no space for it in my case and have to think in Air coolers.... Thinking in going back to the Wrath of the 5600X...
Any suggestion is very welcome.

Welcome to the forums, newcomer!

How is the AIO mounted in your case? Number and orientation of the fans in your case? Make and model of your case?

A 240mm is enough; the chip doesn't use much power. Instead, the 3D cache adds another layer of resistance that reduces heat transfer further - i.e., it's a little harder to cool. A bigger radiator won't solve that.

-Some AIOs have thermal paste pre-applied to the cooler cold plate, and some don't. If your cooler was the latter, did you remove the warning sticker that was there?

-Since you've manually set the pump speed to max, put the cpu under load. Cpu-Z has a benchmark, and there's also Cinebench.
While the application is running, feel both hoses. If fluid flow is good, you may or may not notice much of a difference. If there's a night and day difference, then yes, there may be a problem with the pump.

-Are you choking the cooler of air, by any chance? You've not mentioned what the case is and where the radiator is located.

58X3D is one of the coolest CPUs I have owned, I would check to make sure you are not double insulated with a bunch of TIM, all fans/pumps plugged into the proper headers.

5800X3D can be air cooled easily, AIO not required at all. Check and double check everything mentioned by the others, as I, like them, suspect there is something else going on (mounting, unremoved film etc.). Those idle temps tell a story all on their own. Should be maybe 5 to 10C above ambient.

*Wraith won't be enough for air, you'll need a decentish tower cooler at least, nothing crazy though.

AIO Is mounted on top. I leave the case open for better circulation of air....

I removed the plastic film and aplied my own thermal paste.
Used the CPU-Z bench; at beggining both hoses felt cold. Soon one of them became hotter. the other wae unchanged. I use a very old Bitfenix Colossus and leave it open. Air circulatio is very free and.... for saving my energy bill (very expensive here in Japan) I'm leaving room heating off: ambient temperature around 16C/60.8F

I'm thinking of discharge this Thermaltake and go for a 240mm LIan Li... would you think it will be enough to reach the boost clock? Right now, with all core in 100% frequency goes to 3.7 Mhz top.

That's not normal. It may have been damaged during shipping.
Just double checking, but which header on the motherboard is the pump power connected to? A dedicated AIO_PUMP header's default 'curve' is a flat 100%. Other headers aren't like that, and will require manually setting them to 100%.

FYI, AIO troubleshooting is limited: confirming that it's running in bios and other software, which mobo header, checking the hoses while under a load, rad position in case... eventually it falls to having to buy a new cooler.

Ryzen 3000 and up dynamically scale max boost clock based on factors like, number of active cores, operating temperature, and power(%).
The highest clocks can only be observed when doing little to nothing.

Aye, 'cause it's thermal throttling.
