Air vs liquid cooling?
I need to know what I should go for in my pc.

I am NOT going to overclock, it will be run at stock speed.

It will have an intel core i9 9900k running 32gb ram and an nvidia 2080 ti

here are my options for cooling.

somebody that knows about this sort of thing help me out please :info:

Also while on the subject I understand case is also important in how well the computer stays cool, so I would like your input on my options there too. Currently its using a Coolermaster Mastercase h500, but other options are available.

I think if you upgrade that power supply to something around the same wattage but gold certified you'll be looking pretty good. should double check to make sure the clearances fit with the tall tower cpu cooler inside the case (hopefully these blokes that build it would do that for you) and maybe think about getting a few extra fans to tack on if your case will have room for them. extra fans are probably not totally needed since the case has 3 intakes up front and probably at least one exhaust out the back, but it might have space for a few fans on top to exhause too. I know I was a proponent for the 212 evo but that noctua will do much better on your hot little cpu.

If you aren't sold on that particular case, the only downside to how gorgeous it looks is that the front glass panel can potentially limit the front intake fans. I was thinking about getting the coolermaster h500 for that reason because it comes with a mesh screen front option so they can breathe easier.

That looks great from my house though. That will be a beast of a machine. :cupup:

Fans on top often ruin the airflow unless using an AIO there as the pull some of the cold air away.

You don't need a just a gold PSU and the same wattage. You need a PSU at the same wattage which is reliable and has good quality.
The gold rating does not tell it's quality, only it's power efficiency.

Anything from Tier 1 will be fine.

And I'd usually stick with EVGA (because good warranty), SeaSonic, Corsair, or Be Quiet!
Since you can get them pretty cheap most of the time.

What do you mean? Hot air rises. Why would an AIO stop the phenomina of pulling cold air away vs just fans?
tacoshy 2018 年 11 月 26 日 上午 6:58 
Because an airflow is intend to move in one direction only. That way you get the best flow. Cold air is pulled in from the front moves over the GPU in the bottom and the tower CPU cooler in the top. The hot air from the GPU rises right, but not fast enough. The pressure of the fans is way higher then the weight of cold air (which pushes hot air to the top) It is pushed through the back of the case befor it heats up the tower cooler.

With mounting fans on the top you pull cold air from the front through the top. That cold air won't reach the tower CPU cooler as it is pulled out of the case already befor that. Means you lose a lot of pressure to the rear allow g the hot air from the GPU to reach the tower cooler so that the tower cooler pairwise have to cool with the mixed air from cold front and hot bottom.

I9 9900Ks need a lot of cooling. 8/16 cores in a normal size package. I would defintelly agree with most of these posts recommending an AIO cooler.

No less than a 360mm AIO or a custom loop for something that powerful.

In my experience custom water loops are a ball ache, I want zero to little maintenance so I went back to air and pulled clock speeds back slightly

how much of an improvement is the i9 9900k to the i7 8700k?

I mean I am willing to downgrade if theres not a huge difference and I can still work on my music, game/stream and play in vr without any issues.

All the talk about it getting so hot worries me since my room can get very very hot during summer, I don't want any meltdowns.

The Ryzen 7 2700x would be better suited for streaming.
While the i7-8700k is a capable CPU, it's not as suited well for streaming, since most games these days run on 6-8 threads. And it costs £150 more than the 2700x.
So it really doesn't make sense to use it. Especially when in gaming, they're on par for the most part. (10ish FPS difference.) Unless you're going to play CS, then you'll have about half the FPS, but it's still above 200 fps, so what does it matter in that game?

That way also, you wouldn't have to spend a ton on a motherboard that can supply enough power, or worry about cooling. (The I9-9900k)
So you can spend more on PSU, storage, or monitor/keyboard/mouse, or even fans.

Can't speak for VR, but I asume it'll do the job fine.


As for the original question though.
It would depend on the motherboard, some like to force the 9900k to run at higher speeds for a longer time, so it would result in more performance.
But, when running at what it should normally, it's really not a big performance change, like 4% iirc.

9900k has around 25-30% more than the 8700k when all cores / threads are utilised, as they are the same basic architecture just the 9900k has 2 more cores / 4 more threads, though I'd say heat wise they are very similar as whole far from ideal, the solder on the 9900k is better than the stock paste on the 8700k.

Id really just find a local shop to put a system together for you or scan.co.uk / overclockers.co.uk can put together a custom build if you really don't want to build it yourself which would let you just spec a good air cooler or a 360mm aio and be good to go.

The solder isn't really that much better than the toothpaste lmao.
Monk 2018 年 11 月 26 日 下午 8:19 
Well, it is, quite a lot better I fact, a good 10c or more better I'd say.
Not as good as a full delid due to how thick the solder is to avoid microfractures (the reason Intel stopped soldering their cpu's), but I have had mine benchmarking at 5.2GHz at around 70c on a 360mm aio, that wouldn't be possible on an 8700k.

It's closer to 5c, iirc.
It's definitely welcome, since it is better than the toothpaste, but deliding and putting a good thermal paste in there is better than the solder they used in them.

And there are a couple of cases that people have gotten to 5.1+ghz 65-70 degrees no delid on a 8700k, albeit with custom loops (only CPU.)
So it's possible, chances of getting a chip that does it, 1 in a million.

Luls to people who try to justify paying significantly more for a 9900K when an R7 2700X or i7-8700K will give you more than you'd need.
