Hi Magnus, and others.
First - in the interest of full disclosure. My name is Dennis and I work at Asetek doing community outreach, to help in any way that I can.
I would like to touch on a couple of points here, and everyone is most welcome to ask any questions they might have. I will do my very best to answer
From the latest reply, to the oldest one I want to touch on:
been looking around and found a few:
Thermaltake Floe Riing 360
NZXT Kraken X72
h150i
any of these sound good/bad? the tests ive read about them is kinda the same, quiet, new design etc and good cooling performance.
Magnus. We, at Asetek, manufacture all three of these coolers. Personal opinion is that they're all great cooling wise. However if you like "bling" the NZXT Kraken does offer infinity mirror, which I think is kind of cool. Performance wise I believe many regard the H150i as a slight leader. Thermaltake does offer a lot of RGB, if that's your fancy
IMHO opinion there is no "best". There is what suits your needs and budget.
The Corsair RGB Pro range sacrificed cooling performance for the flashy effects. Corsair recently dumped their CorsairLink software for a bug-riddled iCue software, which is highly unstable.
The Kraken has the CAM software which has more bugs and telemetry than Windows 10, and then some. It will also thrash your SSD/HDD.
Most AIO coolers use ASETEK pumps. These pumps are not known for endurance. Even the 6th Gen used on the Corsair Pro RBG series appear to be no better than the 5th gen currently used on most coolers.
Regardless of what cooler you get, keep in mind that to get "optimal" performance you'll probably want to consider dumping the stock fans and replace them with better fans. If you went Thermal take you'd be in a spot of bother as they use non-standard connectors on many of their coolers.
Anything that uses RGB likely has dumbed-down fans to cope with the extra current needed to power the leds.
So, enough of the doom and gloom.. As long as you are aware of the pitfalls, most coolers perform similarly. Lots of reviews will tout different results, but the tests are rarely apples for apples. If often comes down to the fans.
The case is a minimalist design - so there's nothing really getting in the way of decent air flow.
Ultimately, it's going to come down to budget, and whether you want software control (Thermaltake, Corsair, NZXT Kraken), or whether you will be happy with BIOS controlled fan curves.
Tanyac has some valid points here, and I will try to comment in chronological order.
I agree that there is no clear "better" option. It's down to preferences and budget. Great call!
MOST AIO coolers do indeed use Asetek pumps. In fact, we manufacture a lot of them (complete AIOs).
In fact, most coolers currently use the Gen 4.5 pump (swivel connections), Gen 5 is hardly used, due to it's unpopular tubing routing (through the top lid of the cooler). Gen 6 is indeed in the new Corsair RGB Pro series. Over the last generations we've focused very much on noise reduction. Which means that our Gen 6 pumps are virtually inaudible, even at full speeds (if mounted correctly).
As far as endurance goes. Our pumps are tested and verified for lifespans of 5 years of intense use. However, mounting the pump/block at the top point of your loop, will limit this, as potential airbubbles can get caught in the pump, reducing life. It is actually the same with custom loops, you'll always want to place the pump at as low a point in the loop, as possible. Why? Because they're lubricated by the liquid
Great advice, Tanyac. You've touched on a lot of very valid points
