So I have heard TDP means nothing, it is crazy that you can't just be like ok the CPU is this & so is that air cooler to know it will cool great, that would be great.
 
Yes the published TDP for a desktop chip has ment very little for the past few years. Intel are being a little bit more honest with this 12th gen but it can still be confusing.

If you ask a specific question about a particular chip and whether a cooler is sufficient then I am sure you will get relevant answers. Most people on the forums are generally helpful.
 
I am wanting to put a Ryzen 9 5900/50x in a SG05, but their is no LP cooler that will cool that enough right, with out doing anything to the chip?
 
Well this may be a silly question but why are you putting a high performance chip in a tiny tiny case? and what gpu will also be going into it?

If you pick another case with the capability of mouting a 240mm aio you will be fine but the limited support for 120mm aio I would think that would limit you to a 5600x.

You may want to look in the cooling or case sections to see if anyone else has used this case and what they managed to achieve. My advice is to use a bigger case with support for larger coolers.

Oh, I will, just be so nice tohave a chip like that in a short case. If the PSU was on the case side, I could. What case do you have?
 
I have O11 dynamic with watercooling loop. Full atx and not sff at all.

I am no expert in cases at all but I will use this one below as an example.

https://www.overclockers.co.uk/cool...-itx-case-black-tempered-glass-ca-385-cm.html

Quite small and can fit 240mm AIO at the top so capable of delivering the cooling a 5900x will need. Enough room for most gpus and I think there is a version with a mesh side panel so would not restrict the airflow to the gpu.

You can put powerful components into small cases but it does take more thought and planning than using a full tower like I have. I am sure some people who have used small cases can give you more of an idea than I can about what is sensible and achievable.
 
So, a Ryzen 9 5900x is 105 watss as said on AMD's site & I found this, so just reading that, it seems that cooler is enough . It is not though is it? They need a better system.
be quiet! Shadow Rock LP, BK002, 130W TDP, CPU Cooler, Low Profile

My 5900x uses 120w when I run prime95. It does not use that much when gaming. I would say aim for at least a 240mm AIO or a decent large tower cooler to keep it cool.

Water kind of freaks me out being in a system. Will that air cooler be good enough?
 
It will keep it cool but your on the limits and if the cpu is heavily stressed the fan will have to run near to 100% and will be relatively loud.

Still not sure why you have a need for such a tiny case and what gpu you are going to be using in it

You can lower the chips TDP if your worried about cooling, you will lose a bit of MT performance but ST should be mostly unaffected.

I'm running a 5800X which will try to pull 140w if left to its own devices but I restrict it down to 115w and actually get slightly better performance than stock. You can do this by changing the PPT TDC EDC settings or you can change the chips default TDP settings from 105w to 95w or even 65w.

I have no interest in ovweclocking, if I can run a chip like that out of the box with a cooler like that, with out heat issues, I am all in. If I could find the locked version, that would be good.

Joxeon is not suggesting you overclock the chips , just letting you know you can limit the chip to only use as much power as you want it too. Why would you want to limit a 5900x/5950x to give the same performance as a 5600x when you could save hundreds of pounds by just buying a 5600x in the first place.

I still cannot work out why you want such a powerful cpu in a tiny case and what gpu you will also be squeezing into the case as well.

Agreed, if it can't be it's true self in my sys, I will just save the $$ and get a cheaper one.
