Air cooling vs. Liquid cooling

Hi,
I am confused about which one I should get. I live in a hot humid country, where temperatures could reach 43ºC easily. The only options available for me are:
Cryorig C7; Cooler Master Nepton 240mm.; and Thermaltake Water 3.0 240mm. and 360mm.
It is going to be used onto an i7-7700K.

Also, which mid-tower case will be ideal for such temperature?
 
Solution
As others said the c7 cooler won't cut it. Given the other two options I'd probably go with the water 3.0. Not sure of the price difference of the 240mm vs 360mm, the 360mm would give more surface area which would help offset the high ambient room temps in terms of overall cooling effectiveness. It's fairly large though and may not fit in a lot of cases so that's a potential issue.

Usually air and water coolers are similar when dealing with bigger air coolers. In this case the c7 isn't a larger air cooler so it will suffer. The concept of water cooling is that it should remove heat from the source (the cpu) more efficiently but that heat is then transferred to the radiator where the same hot ambient air will be attempting to cool it...

I was going with a Noctua NH-D15, but none seems to be available. I am in Egypt.

The concept of water cooling is that it should remove heat from the source (the cpu) more efficiently but that heat is then transferred to the radiator where the same hot ambient air will be attempting to cool it and absorb the excess heat. At 40c+ the ambient air doesn't have the same capacity to retain heat (and allow it to dissipate) that cooler 22c air does.

If you can wait and aren't in a rush the x62 would be my first choice out of those aio's mentioned but not sure how long you can wait. With limited access to hardware it may come down to choosing between what's available.
 
Solution
Pretty much agree with synpul...The AIO's should be more than capable of doing a very good job. I would lean to the big Water 3.0 360 because of the larger radiator and thus more surface area. I have been using AIO since the beginning and I have never had a problem..predominantly Corsair AIO's but they all seem to have the same pump tech from Asetek.

You will have no problems keeping the CPU in check with the AIO, even with the temps in your country.
 


OK. Thanks!
