The never ending debate

[xDoron22]

Hey everyone. Sorry if this was asked before but I tried searching for answer online and over youtube but couldn't find a decisive answer.

 

I'm buying new computer and I will be getting the new ryzen 5900x , currently looking for the best cooler for it. 

 

Air or liquid it doesn't really matter, even the price is not an issue (though if I could save few bucks than why not).

 

General idea of use:
- Stock speeds are 3.7 to 4.8 GHz
- Not gonna overclock at all.
- Noise is a factor for me. Would like the cooler to be as quite as possible while maintaining good temps.
- As I understand, ryzen CPU's suffer a lot of performance drop while not being as cool as possible, So ideal cooler should make the cpu work at it's max boost speed (4.8 GHz) as long as possible and necessary.

Some coolers to consider:
Be Quiet! Dark rock pro 4
NH-D15
Kraken Z73 360
Arctic liquid freezer II 360
EK AIO 360

Thanks for the help ✌

Don't buy anything nzxt. 

 

PSU on top is better than bottom. 

 

Because. 

 

 

Hot air. 

 

 

 

Goes.

Hehe

Sadly for me.. im also fixed on getting the fractal R7 so the PSU is going to the bottom

 

What about the coolers though, Any idea?

If in doubt always go noctua imo!

in side a controlled environment like a case air goes where you tell it  to go. it doesn't if it is hot or cold. unless you design a case around convection or assisted convection

if your going to want get the max out of your cooling your going to want a case with better better air flow. id recommend the

fractal meshify c tempered glass or dark tempered glass

pretty much the same design just with a mesh front panel.

 

 

the best cooler in your your list is

for water

arctic liquid freezer II 360

for air

NH-D15

Not accurate,Hotter air is lighter than colder air,so the hotter air goes up.

But if all the air is hot than it will all behave similarly.

It's a relative thing.

If hot air is rising in your computer case then you aren't moving enough air. Air should flow front to back. If warm air is rising everything in your case will be heat saturated, that's not what you want.

The 4.8GHz boost is for single core,

Right but having the PSU in the bottom part doesn't help that at all, and by additionally putting it in a cage like most "modern" cases do you're also removing an otherwise additional exhaust for *hot* air... 

 

And the thing about going front to back is correct but if the PSU is top or bottom does have no influence on that at all... You'll still get some hot air from the bottom if there's a PSU heating up all components, unnecessarily, though, which you then 'fix' by putting more fans (which a lot of people simply don't care to do...) 

 

Granted I don't have a lot of experience with that, but logic suggests that having a hot/warm part in the *bottom* doesn't make a lot of sense because you'll have warm air going through the whole system, needlessly... 

 

But the experience I have in comparing my case which has the PSU at the most logical position against a similarly priced case that has it in the bottom at least strongly suggests that logic is is indeed logic, about 10-15C difference, which is incredibly huge, all things considered (same amount of fans and everything)!

Bottom PSU fan down and spinning fan, the influence to air case temp is negligible.

Top PSU with fan down will help to move hot air from the case, but it will rise the PSU temp, that not recommended from PSU side.

The air coming out of my PSU right now is cool, as it is drawing fresh cool air from under the case, and my PSU is cool to the touch as well. So in my case, my PSU is not putting out any heat, in fact, it is difficult for me to put a heavy load on it, being 850w. Best I can do is about 500w at the wall unless I run something silly like furmark. Looking at the fully featured pc you have listed in your sig I am not surprised your 500w PSU gets warm. Especially since it is drawing air from inside of the case. I also prefer my PSU down below for a lower center of gravity to help resist bumps because kids..

bottom mounted psu's(99%) -

it pulls air though the bottom and exhaust out the back it doesn't go into the rest of the system.

 

top mounted psu's-

air is pulled in from the system the exits the back. aka the psu act as an exhaust for the system.
