ryzen 3800x temps on custom loop

Hi,

Just did a custom loop using barrow parts.

 

Cpu seems quite high 50-60 idle and 70 under full load.

Although my noctua d15 was thermal throttling so im thinking ryzen cooks. 

 

while 2080ti is sitting at 35-40C

 

does ryzen stay hot even under water?

or is it  a bad mount/cheap water block?

 

i remember my old 4790k was like 40-50 under full load with a water cooler.

 

PS using a 480mm thick radiator

I'd check the mount first.  And then pump speed.

 

What is the ambient temp of the room?

Barrow's blocks are good. Ryzen does not run hot, especially a chip as weak in heat as a 3800X. If it carried over from a D15 to your loop, either 1. it's you, whether you like it or not, bad mount or you aren't applying TIM properly. Or 2. your case airflow is oven worthy. It could also be a defective chip that wasn't soldered properly but that is unlikely.

Well thermaltech p5 so no airflow issues. 

Here is an image off d15 thermal paste it looks good I used line method cos that's what I did on my first cpu.

 

Also saw gamersnexus video showing how hard it is to screw up thermal paste.

 

Also if you had bad mount wouldn't that make your cpu overheat.

But only getting 10C variance when running prime 95 vs fully idle. 15907272922693439170845194159610.thumb.jpg.c81403ab8a62113abe97c3fff4d93ef6.jpg

The low delta means the heat isn't making it into the cooler. It looks like your chip is suuuper convex as well. Could simply be a really unfortunate IHS shape, though it shouldn't be that terrible. Bad solder is still a possibility, but a doubtful one. If you set the chip on a table, pins up, and try to spin it, does it spin like a top? If yes, you have a very convex IHS, which is likely causing such a drastic issue, combined with other factors most likely.

How much pressure are you using when you mount your cooler?

The surface area doubles with 3900X and 3950x as those use two chiplets. So those are much easier to cool with 140-150W than 3800X with 90-100W.

Doesn't make the 3800X hard to cool, however.

Its physics. The smaller it gets, the harder it is to transfer heat out. Nothing complicated.

 

Bad block design could lead to high'ish temps too with 3000 zen2 as the chiplets are not centered. Its nit-picking level stuff but it can matter if you add in convex heat spreader with convex cold plate.

This would not transfer over to an NH-D15, however. And yes, I'm aware of those physics. It does not make a 3800X hard to cool, however. Harder than other chips, yes, but on an absolute scale, it's not hard to cool, especially by a D15.
