Do i need water cooler for i7-9700k?

Do i need water cooler for overclocking to 5ghz for 9700k?

I am thinking about a ma610p or a ma 620p, which one will be better?

Considering that AiO Water coolers are often worse in performance than Air coolers while being usually twice as expensive no... you don't need water cooler for the i7 9700K just don't cheap up on the air cooler you get.

you could probably get away with an NH-D15 if you dont want an AIO

A noctua nh-d15 is ideal if you want to do overclocking on the 9700k for 5ghz.

No and both of thoughts coolers will work but if you go with water you may be able to push your overclock further

You don't need a liquid cooler, but I wouldn't say those air coolers aren't quite up to the task either. I'd go for a dual 140mm tower cooler such as the Dark Rock Pro 4 or NH-D15, provided your case and budget can fit it. Between the coolers you have specified though, the MA620P is a dual 120mm tower and it might be able to do it considering a full-copper 120mm single tower cooler was able to keep Anandtech's 9700K cool at 5GHz.

I also am a fan of air cooling. 

I see it this way: with water-cooling you are only going to cool the water to ambient temperature under normal circumstances.

 

With air cooling you will already be blowing in ambient air if the case is setup for it.

 

So in my simplified theory, both coolers will cool to ambient temperature. One has more failure points and is generally more expensive (AIO's) and the other has fewer failure points and is generally less expensive (Air coolers)

 

{I am ignoring the scientific stuffs about thermal transfer and didsapation rates of water, vs air or the gas substance they use inside heat pipes, at the cpu block because I'm not that smart}

 

I also think air-coolers look cool

 

noctua sells chromax fans I highly recommend and chromax covers for their heatsinks (and even chromax heatsink fans) too so you can get rid of the noctua brown for your build color.

as someone who ditched AIOs, here's a couple of things.

 

only the x62 and 150i performs better than a d15 or drp4, the others are on par or slightly worse.

 

When the pump dies it's useless (and they do), even if the fans fall off an air cooler the cpu won't explode just yet.

 

those beefy aircooler cool the vrm, but u can also just rig a side case fan directly blowing at the vrm with AIOs installed.

would cooler master ma620p or ma610p do the job just fine?

I don't really care about the temp as long as they don't throttle

Not for overclocking. You need good cooling to overclock more.
