I'm building a new system in a jonsbo u2 case, but I was wondering whether i should go for a top down air-cooling to blow air to the motherboard, or go with watercooling and opt for easier maintenance and dust removal.
Just to emphasize, I'm not concerned about cpu temps because i know that both methods are sufficient enough for my build. It's the temps of other components im concerned about in the long-run.
So, which do you think would be better, watercooling or top-down aircooling?
Specs are gtx670 i5 3350p corsair cx600w.

i would say get a decent air cooler for your cpu like a hyper 212 and set up a custom loop for your 670 to overclock it. unless you want to put a waterblock onyour cpu just for looks then its not worth the money or time cause you cant overclock it.

Im not intending to do any overclocks (and hence am not concerned about cpu temps, as i have emphasized). The purpose of watercooling is for dust maintenance and motherboard ventilation in a small form factor case.
And as I said , I will be getting a top down cooler like Geminii m4, not 212, if i was to opt for air cooled solutions.

yup, your cpu doesnt allow for overclocking.

what i meant was having a water loop for your graphics card to overclock that.

it is best to have more cfm coming into your case than going out to create positive pressure. by having dust filters covering the intake fans you eliminate dust buildup.

as far as keeping your components cool, if you have 2 intake fans and 1 exhaust. that will give you sufficient cooling in a case.

another way to look at it is if you were to have 200 cfm coming into your case and around 100 cfm being exhausted.

hope that helps

Please look at the case i will be using.
gpu waterblock is near to impossble, plus i have no plans of doing so anyway (i had enough with gpu oc in my last build) and it only accomodates one+one for in/out ventilation. Coupled with intake fan from the top mounted psu, theres no way i can maintain positive air pressure; even if i get a 100cfm case fan (fyi, corsair af12 is rated around 65 cfm), which is way too loud, actual intake cfm will be much less with jonsbo u2 because the intakes are from the sides, not directly from outside.

I cant get noctuas in my country, besides, nf-p12 are overrated and overpriced. Cfm (56) is too small to meet the demands of intake fan in my case.

well, there is going to be a compromise somewhere, rare to find a low cost high build quality and performance product with anything.

if you put any fans that are corsair or something you should be good, i dont know the availability of fan manufacturers in your country.
