Question Cooling for i9 9900K cpu

[Aorus73]

I have buy one 9900k and i need 1 aio or 1 water cooling is a good idea second you?
So for Aio i have thinked at asus riujin 360 with noctua fans thermaltake floe riing corsair h150i or Next x72 and for the water cooling kit i have thinked at alphacool or ek ever 360 what do you think?

Hi guys,



Hoping your’ll can help. I am building a new gaming/animation pc. I have ordered a core i9 9900K. I need to get a cpu cooler for this cpu and was looking at the Cooler Master Masterliquid Pro 240.



Do you think it would be sufficient to cool the i9 9900K cpu overclocked to 5.0Ghz or should I rather go with the Corsair H115i Pro?

You need to do more research and decide.

A custom LCS system is not on the same bar or league as a "kit" as Kits are always missing something, or they are brand specific, and no single brand makes everything the best.

A custom LCS system will also cost you significantly more then a AIO will, will also offer that much more flexibility provided you have room in your case for it, and is a lot more fun as a hobby to do.

Did i mention i have yet to meet / teach / guide anyone who actually stayed on there original budget?
Watercooling can get expensive.

So you think that an aio is ideal for i9 9900k?
In aniway yes i have see guide on Youtube for the water cooling for me is my first loop!
Ah my case is one h500m from cooler master!

 

[aigomorla]

the 9900k when high overclocked has a massive power draw.
This in turn means it will generate a lot of heat.

I dont think any AIO will make you happy, as it wont be easy to keep in check, if you want those high clocks on all 8 cores.

For stable daily use for the moment!So 5.0 5.1!

 

[aigomorla]

5ghz on all 8 cores is not an easy feat....
Its not something a novice can pull off or something you can expect to hold constant and stable all year long unless u live under an Air Conditioner.

AIO will not be sufficient on a cpu that can draw 250W+ at that overclock.

Good Luck...

You forget the 9900k is not the 8086k.
You have 2 more cores on the 9900K and those 2 cores from looks of it adds a LOT more power draw and heat.

If you want something to handle that, you will need a full bloated custom LCS, with strong head pressure and good injectors directly over the die... ie... a 90 dollar waterblock itself component paired with a good thick radiator rated at 500W if you want to conserve your hearing from fans required to pull that heat out.

If is 4.7 or 4.9 is a goal for me!

Actually a 9900k @ 5.0 GHz ought to pull no more than 207W according to AnandTech:

https://www.anandtech.com/show/13400/intel-9th-gen-core-i9-9900k-i7-9700k-i5-9600k-review/22

Maybe you can push higher power usage in Prime95 or what have you. Outside of that I think an AiO would do just fine. Hell my D15 is handling 200-210W from my 1800x @ 4.0 GHz in synthetics. Granted I have IndustrialPPC fans on it making a racket. But still.

I think an AiO will be fine, the kits are not worth the money. Just get one with a 360mm rad that isn't faulty like one of those Liqtechs they sold for Threadripper (ugh).

edit: also AT used a TRUE Copper, heh.

 

[DrMrLordX]

We basically have the same thread twice, heh. Can we um, consolidate?

 

[aigomorla]

Merged the two threads together as they are both the same question with both the same wants.

Brilliant. Thanks aigo.

Okay, I wanted to bring a little more data to the table to justify some of my commentary:

https://www.anandtech.com/show/13219/the-corsair-h150i-pro-rgb-aio-cooler-review/4

Fiddle with the temp menu (it has data for heat loads of 60W -> 340W) and you'll see that the temps above ambient never get that high. Note that some of the 280mm rad AiOs actually perform better than the reviewed unit (notably the Kraken x60; the Kraken x62 is basically the same thing, only updated), so I'm still a little surprised by that. Might be down to res thickness and fan speed, I don't really know. None of these reviews like to explain the performance differences that are unexpected.

Now granted we're talking about a 340W thermal resistor and not a 207W CPU, so hotspots etc. become a concern. Still, AiOs CAN handle heat loads from a 9900k, push come to shove. They have the pump and reservoir to do it. And if I keep seeing 280mm rad AiOs beating 360mm rad AiOs then I might have to rethink AiOs at some point. The 360mm rad units should be the top performers. And yet . . .

Anyway from some of the testing I've seen, it might be that the best AiOs to get would be ones like the Kraken x62! Though I saw at least one test where the Thermaltake Floe Riing 360 TT Performance Edition did just as well, albeit with a larger rad.

I was able to sufficiently cool my 9900k @ 5Ghz all cores with a H150i. This of course was in October so the room temperature was probably 5F lower than summer, but that's not a huge swing. Now, with a custom loop, both the 9900k and 2080 Ti at full load is not a problem. The fan and pump are set low enough to not be audible and the curves don't ramp up unless the CPU goes above 70C. That only happens if Prime95 runs for a long time which is not typical usage.

As far as ease of overclocking, it was pretty straight forward. derbauer has pretty easy to follow video if you need something to follow. It's meant for the Asus boards, but most of the settings translate over to other manufacturers.

I take a look at the video

It might be an issue with the pump power vs volume of water; you are pushing water into a X volume, where this volume is smaller, you would have faster circulation ... maybe ?

Fluidodynamics isn't my forte.

 

[Aorus73]

Ok i have decided that i go with ek and i buy the component when i make the configurator of custom loop in the site of ekwb and i go with rad se 360 and se 240

 

[KentState]

There are better options than the SE rads from EK. Check Hardwarel Lbs and Alphacool. Since they all use the same size fittings, you should be able to shop other manufacturers.

I went with a 360 PE and a 360 SE so stayed with EK, but if do a slimmer radiator, I would have gone elsewhere.

 

[Aorus73]

Ok i have choose the aquacomputer water block kryos Next with vision

Larger rads typically offer more resistance to flow. So you're sort of on the right track there. Larger rad + same pump maybe = problems.

I was able to sufficiently cool my 9900k @ 5Ghz all cores with a H150i.

I figured an AiO was enough. @Aorus73 if you needed some proof that an AiO will work for you, there you have it.

 

[ViRGE]

For what it's worth, I'm cooling a 9900K@5GHz with a Corsair H115i Pro, and everything is peachy.

 

[DrMrLordX]

Jolly good then.

240mm rad, so . . . meh. I've already recommended the products I think would work well for you. KentState is using an H150i so ask him about it.

Yeah but i think if i put a second rad maybe
