Fan recommendation

[davel]

I have a Lian Li Lancool PC-K7B and have had it for 4 years and I don't think I get the best airflow. I think I need to change the fans, I have 3 one in the rear, and 2 in front. All 120mm.


I am mostly concerned about the summer when it gets really hot. I like to keep PC on 24/7 though most times it idle except at night when I use it.

So I am curious what fans are the best for cooling. Noise is not an issue for me at all. I rather it sounds like a jet plane and be cooled.

I figured I would replace all 3 fans when I do my new build in next week or so.

Maybe something like Scythe Slip Stream 1900? Moves a lot of air (110 cfm), cheap and even though there are a lot louder fans that move more air, they actually sound like a jetplane. I don't think you really want that...

What is the most important stat to look at?

Rpm or cfma?

RPM is the speed it rotates (you probably know this), so the more rpm the louder. How much air it moves per rotation depends a lot on fan model and manufacturer. You want something that moves a lot of air, so CFM is probably the most important aspect to you.
Blindly looking at airflow numbers isn't very fair though, there are a lot of other factors weighing in, for example static pressure which helps for fans mounted into heatsinks. The Gentle Typhoon is better for this for example.

If you want jet engine sound and max cooling get a 5000+rpm delta such as this one:

It's a very well made fan that will easily last 5 years at full load. I used to use them in servers all the time, no way would i ever put a 5000+rpm fan on my 24/7 computer but you did say you dont care about noise and nothing is going to move more air that a high rpm delta fan.

If you do decide you actually want to be able to hear yourself talk in the same room as your computer and decide to go for a lower CFM/RPM fan the the scythe linup has some great fans at good prices. This is a good one:

Crap, thanks for reminding me I live in Florida. Can't wait to see my cards idling at 90c...
