This can't be true...can it? [Integrated loop vs Custom Loop]

post #1 of 37
Thread Starter 
So I was reading Computer Power User when I came across an interesting article about the Antec Kuhler H20 920. In it, they compared it's performance to that of a custom loop with a 240mm rad.

They had three categories:
1. Price - Okay, of course the Antec will win here.
2. Installation- Once again, it's a given the Antec will win, no filling or bleeding required.
3. Performance- "As it turns out, the Anter KUHLER H20 920 blows our pricier and more cumbersome custom setup right out of the water...it managed to keep the load temperature of our overclocked Core i7 990X 3.34 degrees Celsius cooler."

Thanks, GingerJohn, for Source

What? I thought it was a known fact, at least among enthusiasts, that a custom loop will always perform better than a closed loop like an H70 or Kuhler 920?

Maybe I just haven't read enough about it? Can you guys out there with custom setups and H70s/920s chime in on this issue with your temps?

Thanks guys.

EDIT: Thanks to homestyle, realized that this so-called "review" is actually an advertisement. The more you know...

Well, if you want to only cool the CPU and that's all. Then go with a sealed loop, get one of the corsair ones though, better warranties.

If you want to cool CPU and GPUs and more with water, go with a custom loop.

What did they specify about the custom loop? Could have a horrible pump or fans or something like that.

Without even reading the artice im thinking....magazine? biased opinion?

Depends on the loop used aswell,i mean...you could always make it a crappy loop right?

They didn't really specify what their loop consisted of, just that it had more rad and it was CPU only. Also, let's throw out the speculation on bias. I'd like to assume absolute journalistic integrity and just collect cold hard facts. Is it a common phenomenon that sealed loops beat custom loops in a CPU only configuration?

Also, how "crappy" does a loop with a 240mm in it have to be to lose to a sealed loop cooler? Let's establish the point at which it becomes more reasonable to go with a sealed loop than custom.

Might be helpful to add the Source to the OP.

They don't mention anything about the custom loop except for 240 rad, 12W pump and 1/2" tubing. They could easily have used a poor CPU block, or mismatched the rad / fans (e.g a BI GTX with 1000 RPM fans). They also don't say what speed the H20 920's fans were running, or how loud each system was.

True or not, without detailed testing specs the conclusion is useless.

Very uncommon. Seriously, the article gives no real details of equipment, test setup or methodology. I would hardly call that a reproducible test.

Ideally a well performed and reported test should be repeatable by an external person, with very similar results. For all we know the ambient temperature could have changed between the two runs, they could have used different chips for each run. They don't even mention the stress test used. For an example have a look at some of Martin's or Skinnee's excellent tests, they give enough details for you to reproduce the test yourself.

Bottom line, poor test is poor. Do it properly next time and I might give it a second look.

Depends on the CPU block they use, the pump and radiator. A lot of factors to take into account...

I've noticed that CPU Mag is getting whacked out. They are recommending some junky products. They have a love of Lucid too.
