Choosing case fans

[pathsny]

Hi
I have a nas with about 7 SATA hdds sitting in an NZXT source case. I've noticed that drive temperatures can climb to between 45-50C. Since the case has space for multiple fans, I was thinking of sticking a couple of 120 mm intake fans at the front to aircool the hard drives. This should pull air in and between the drives.

I want the fans to be quiet and to reduce hdd temperatures. Should I get a static pressure fan or an airflow fan? Any recommendations for a good but cheapish fan I can use (since my requirements seem pretty modest given the temperatures?). I was leaning towards the corsair AF 120mm quiet fans. Any thoughts about my choice?
thanks

The ones you've picked should work out fine.

spcr is a good source for quiet computing.
Here is one article on 120mm fans:

You can get any amount of airflow you want if you are willing to pay for it with higher noise.


If all your air intake is from the front two 120mm fans and is filtered, your case will stay cleaner.

I might remove the 140mm top exhaust fan and leave the rear 120mm exhaust.
A strong 140mm fan as exhaust will draw in air from nearby openings and not from the front so much.
You want max airflow to come in from the front where it can cool your hard drives.

Put your hottest drives on the bottom for more airflow.
If you are not using the 5 1/2" bays for a dvd drive, look for a fan for the top three drives.

I only have the rear exhaust fan right now, so that looks like its good. I notice that there are SP fans and airflow fans. SP fans are described as "for radiators", but articles usually talk about blockage. I dont know if airflow flowing between drives counts as blockage.

A little of both, I think.
But I think the type of fan is a second order consideration for cooling vs. rpm.
