If a seal goes or a connection is duff, it will leak. End of.
Silly claim undermines confidence.

Just under the last image on the first page, you've said it uses 140mm fans, but they're 120mm. Needs fixing

Totally agree. You could say "overpressure control" or some other snazzy type thing but entropy being what it is, this will eventually leak. They've just solved one of the more likely causes of leaking with quite a clever/simple passive system that doesn't massively add to the complexity.

What I want to see is a pressure monitoring system (just a simple pressure switch will do) that, when the pressure drops does two things:
1) sends a shutdown signal to the BIOS to stop your CPU a'cookin'
2) injects a chemical which instantly turns all the liquid into non-conductive foam which seals the leak and any residual escaping foam is readily managed.
3) as its final act, sends a signal to your speakers where it boldly announces the phrase "oh cock".

On the flipside they've added two more ways for something to leak if a seal goes either end.

Ahahahahaha

There's a far easier way to do this without a seal being involved. You just pop in a balloon which is pressurised to the pressure at which you want extra volume to appear and it'll collapse under the pressure of the liquid creating extra volume.

Plus, you really don't want a seal popping inside your PC. Blubber gets everywhere and the screams of "arrrrrf" just before the pop are quite distressing.

Just in case anyone was wondering about the potential for exploding seals in extreme temperature conditions, Youtube provides:

I guess the conclusion from these results should be to get the dark rock pro 4?

Seems that's been fixed, but further up is a reference to it having a similar sized radiator to the NZXT Kraken X62, Corsair H115i Pro and be-quiet! Silent Loop - all of which are 280mm rads.

And I thought the 240 in the model name referred to fan size. Perhaps a little optimistic on my part. :-)

[raygdunn]

Ah think advertising... two fans.

120+120=240

Effectively, yes. All AIO water coolers tend to offer similar performance to the best air coolers, but typically at twice the price of the equivalent air cooler.

I know they seem an attractive option, and a custom loop *starts* at around £200 for a bare bones basic and £300 for something half decent, but AIO watercoolers are a bit of a strange product imo. My view is that you should stick to either Air cooling or a proper custom loop and that AIOs just don't have a sensible place in the market.

Then again, if you add RGB to something it will sell...

[Iota]

AIOs just don't have a sensible place in the market.

If you travel with your PC to LAN events etc, the bonus to the AIO is less strain on the motherboard, also good for clearance for some RAM kits / cpu sockets at a guess. Personally I wouldn't swap mine out for an air cooler if you offered to pay for it, it's quieter and keeps the cpu cool enough for my purposes.

True enough - there potentially is a case for it when you are looking at pure aesthetics and space/weight in the case. A PC that moves about a lot is a great example A good air cooler will be just as quiet as an AIO though (if not quieter) - a kit like this which has 2x140mm fans running at say 1200rpm will be louder than an air cooler with 1x140mm fan at the same RPM...and most of the better ones end up with 2 so you end up with the same noise level.

I would not suggest you swap yours out either More that people should be aware that buying an "AIO" watercooler will not give you all the benefits & cooling performance that a more traditional custom loop will give you, and you are paying typically twice the price of a good air cooler for the same end performance.

It's also worth remembering as an aside that the vast majority of AIO systems out there are based on the same setup - they almost all use Asetek radiators & pumps (typically the same ones) with the main differences between them being the CPU block, fans and lighting. Thats a big reason that the vast majority offer the same performance within a couple of degrees. Not an issue, more of an interesting observation

Current price for the DRP4 is £70 on scan.

Failure on a plain heatsink means the other fan automatically spins up because it's all PWM. Failure on an AIO might be far worse
