i7 970 with Noctua NH-D14 better than CoolIT ECO ALC?

post #1 of 15
Thread Starter 
On 4Ghz with 1.288v I get temperatures around 70 - 80 celcius with CoolIT ECO ALC "closed water cooling system" when running FTT with Prime95 ( 100% load ).

I was wondering if getting a Noctua NH-D14 would lower those temps a lot? Anyone got experience with Noctua NH-D14 + i7 970?

You might lose some, but not that much.
The advantage of a decent watercooling system is that it can handle high temperatures over a longer time period, and when ambient temperatures rise it's efficientcy is higher than an air cooled module.

Even though a lot of high-end air coolers come pretty close to the performance of a watercooling system.

videocards is where watercooling really has an advantage compaired to air coolers.

Yeah, but you are talking more about the custom made watercooling systems right? I have one of those "cheap" closed systems. This one: http://www.coolitsystems.com/index.php/eco.html

You still think this water cooler outperformes the D14?

Difficult to say for shure. Since every case and room is different when it comes to airflow and ambient temperatures.
I'd say the come close to each other no matter how you put it smile.gif

If your case doesn't have the best airflow it might be best to stick with the watercooling and trying to put the radiator fan as intake for the best results.

I have the radiator at the rear with two fans pulling air into the system. Then I have one 140mm noctua fan pushing air from the top and one fan on the wall / side pushing air ( noctua 140mm ) and in the front I have 1 noctua 120mm and 1 fractial 120mm pulling air out of the case.

My ambient temperatures are ~25 - 27 celcius, it's quite warm here even if it's winter.. The CPU case never really peeks above 61 celcius and according to intel 67.x celcius is the "max" casing temperature.

I'm just a little ambivalent about if the D14 will performe better than the CoolIT stuff..

Edit

Some other interesting temperatures (FTT full load):
Radiator: 41,4 celcius
Case air: 36,1 - 37,6 celcius

I think air cooling is better than these pre-made water coolers. Every review agree with that

That's my point of view too. I wonder how many celcius I can decrease by getting one of those though.

Here's a review where they compare the NH-D14 to a CoolIT. I haven't read it all so their methodology may be questionable, I have no idea.

However it should be no surprise that the NH-D14 beats out the CoolIT comfortably.

D14 beats the Cool-It afaik. The Cool-It's radiator does not have that much surface area to dissipate heat.

Wow 10 celcius less, that's quite nice..

I've got a thermometer on my cool it radiator and it's "stable" at 41.1 celcius after ~5 hours of FTT. Which is Quite hot imho.

Might be worth getting a D14 then. Another question is, how do I know if it fits on my MSI X58A-GD65 ? I've got Corsair 6GB (3x2GB) 1600MHz PC3-12800 XMS3 ram modules so they're not really that "high".
