True or not, without detailed testing specs the conclusion is useless.
My thoughts exactly, doesn't sound very accurate to me, the sketchy details only make me think the test was heavily biased.


Come to think of it, I've seen people say high end air cooling is better than that seal liquid unit, so by that reckoning high end air > high end water...


lol

Well I have to say that those high end air coolers are pretty much done right out of the box. If you don't like the temps there isn't a lot you can do to them to bring the Celsius down.

Whereas the H50 gives you a little more you can do to bring the Celsius down. My personal experience is that I was able to lower my temps by lapping the contact plate. Most High End Air Coolers are already lapped or the thin walled heat pipes are exposed and don't lend themselves well to lapping.

The single fan can be replaced with dual fans of any variety and speeds. But the fans that have a solid static pressure as you well know will give the better results. This logic does not apply to Air Coolers.

Air coolers only mount 2 ways. Exhaust or Intake and cannot be mounted away from the CPU. Whereas the all in one setups can be mounted away from the MoBo to rid the system of the heat without being overtaxed by increasing temps from say a Fermi. This allows better cooling imho.

Most air coolers are also not able to run a shroud on them backing the fan off the vanes and allowing more flow to cross the surfaces of those vanes.

Those high end coolers however are aided by running them in Exhaust in the direction of an Exhausting fan. Which helps them tremendously.

I don't think the H50 or the Antec Kuhler or any all in one is the greatest cooler. But the High End Air Coolers are not that much better than an all in one cooler. My

Fair point, I think for high end air though, people do a lot to make sure much of what you said doesn't affect them.

I didn't know that about the fans though, I had assumed that most heatsinks worked in a similar way to rads in that higher static pressure produces the best airflow through.


My biggest concern with the high end air coolers though has been the size of them. Some of them are over 2kg with fans! Mounting that on a vertical mobo...

But mix that with a large high airflow case and you can make some pretty numbers...

Figured I would chime in here, I actually just uninstalled the Antec Kuhler 920 off one of my rigs and it's going back for a refund. It wasn't a bad product, but dang it sure wasn't good either. Let me put it in perspective. Antec Kuhler 920 on full fan (which is unbearably loud) approx 2400rpm's, same temps as my thermaltake frio with 2 enermax 1500rpm fans... which are very livable in the sound department. I was hoping the Kuhler would deliver the performance over the Frio to avoid a full out water cooling setup, sadly it disappointed and also had a intermittent pump noise that was annoying.

In case someone questions my experience with said coolers here is pics of my rig with both.

I looked into the sealed units but other then the size issue the best Iv'e seen them do is match a noctua d14 but a lot noiser

well the biggest governing factor in any loop is being closed or custom:

#1 pump
#2 rad
#3 heat transfer


these 3 things must work in any loop to be effective

A more accurate representation would be the H20 920 vs XSPC Rasa RS240 as they are at the same pricepoint...

The RS240 would effectively whoop the 920...
