Antec KÜHLER H2O 620 / KÜHLER H2O 920

I was considering the H2O 920 for my next build, but I'm currently waiting on funds, and to see how it will stack up against both of Corsair's soon to be released offerings, the H80 & H100.
 
Bought the Antec Kuhler 620 on special offer from a competitor. First impressions are very good. Installed dual fans as intake from the rear of the case. i7 [email protected] idles the same as my Tital Fenir (35-40c) but load temps are cooler for sure, after an hour of prime95 max temp was just 69c (ambient room temp was 25.5c). Will be reaseting cooler with IC Diamond next week so will give better feedback then. Great piece of kit for money.
 
I think the manual suggests installing the fan and radiator as exhaust. Problem with my setup is that the gelid icy vision cooler on my GTX470 doesn't exhaust hot air out of the case so the radiator would have this blowing through it. Currently have it setup as dual intake fans on radiator from the rear, dual exhaust on top and front.
 
i'm gonna have 2 gigabyte 560ti's in the case, they're not out the back exhaust but internal exhaust i'd assume(windforce versions) so intake would be best for me?

i've also got a 200mm fan coming for the top of the case
 
ive got the antec kuhler 620 its alrite going to get silver arrow though as ive tried this cooler with ic diamond and artic silver but my temps hit 83c on full load on a 2600k overclocked to 4.8ghz idle it sits at 39 which isnt bad, but my prime temps are to high for me, ive even got 2 apache fans on the rad doing push/pull on full chat and a cool air intake 12cm fan on the front

dont get me wrong its a good bit of kit but it doesnt quite hack the type of overclock on my setup.
 
I have always wanted to try watercooling, but have never invested in it because compared to top end air coolers I can get great performance for a lot less cost. Although these 'all in one' setups are constantly taking my interest. Due to their competitive price. I'm more interested in having a cooler pc rather then a faster one as I only overclock my pc when it starts struggling with things.
 
I got one from OC Uk. Fitted it instead of an Arctic Freezer pro.

On my i5 2500k @ 4.6ghz. Prime temps in mid to late 60's.

Dropped load temps by 10-15c. Fitted the case fan in push pull.

Its an intake on mine with front case fans drawing out and 200mm top fan.

Made more sense to have cold air from out side cooling the cpu. Case temps and
GFX card temps were fine.
 
Hi all, i'm hesitating between a Antec KÜHLER H2O 920, and air cooling : maybe the NH-D14, but this is not the subject here.

I've looked into several reviews for this Antec KÜHLER H2O 920 water cooler.
These two are the most interesting, as they also compare it to air-coolers :

What i like about this water cooler :
- it's definitely cooler than an air cooler !
- easy to mount, and NO maintenance !
- it takes less space than an air cooler
- it's less heavy on the motherboard, which could important when i'll move my computer from place to place

What i don't like about it :
- apparently it's a lot more noisy than a cheaper high end air cooler (for example the NH-D14)
- if you use it in "silent mode", then it doesn't cool more than a good air cooler
- but... maybe that you can get both low noise and good cooling, if you change the fans with silent ones (that's extra cost, but could be worth it)
- if i read well, it cools the CPU more, but it cools the motherboard less. Air coolers will cool both. So, you might have to add an additional fan for the motherboard too.
- the price, especially if you also have to get additional silent fans
- there's water inside, which still makes me a bit scared (^c^) I'm aware that this is maybe stupid. It's maybe a bit like people who are afraid to take the plane, it's hard to get over it
- i am scared that with this "no maintenance" system, it gets clogged over the years : i wouldn't want to have to change it every 1 or 2 years because it's clogged and you can't clean it

I'm looking for other people's views.
Tell me if i wrote anything wrong.
I hope that people who used these water cooling systems will give us insight about how they behave on the long term.
