Hi, I need to cool an ATCS 840 with four 120mm fans and I can't seem to decide which is the best compromise between DB and CFM. Need some suggestions.

i use Scythe SY1225SL12SH 120mm "Slipstream" Case Fans...

you can get them pretty cheap on newegg if you buy multiples. they can push good amount of air, but in my opinion, they work best with a controller and backed down from full speed. they stay very quiet and can be pushed when you need it. not sure if you might like that idea.

i am guessing if you save money on the fans you can totally buy a simple fan controller and get both quiet and flow when you need to adjust your feelings.

i have been using a set of 9 for about almost 2 years now and they are running great. the oil port on the back is easy and has a rubber grommet so if you oil it every once in a while you can use them for a long time. been happy with the scythe brand, dying to try out the quiet typhoons though... heard those are amazing too...

my impression is noctua seems very expensive? and the kama 2 is okay, but according to spec, i personally would still take my slipstream over those 2. if you buy 4 @ 8.39 each... definetly are very affordable for great fans. i bought mine for like 15 each back in the day if i remember correctly...

I've been considering Slipstream along with the other two and after your post it's just another point that goes to Scythe. I'm quite disappointed I can't seem to find Gentle Typhoons in my country at a fair price, it seems a great product. I'll be surely buying a fan controller, I'm thinking about Scythe Kaze Server 4 channel.

The slipstreams are great case fans, but absolutely suck with any kind of resistance. So don't use them for anything else than for the case

yes, i agree... gentle typhoons are just too rare and priced too well...

i think for now... the slips are perfect over all. i think the best i can find for the gentles are like 13 bucks? and i think there is a guy who sells modified gentles? i forget why, may be they were faster?

i recommend get something that you will use for a while. i think most will be able to run 4 fans just one 1 channel. so if you get a 4 channel i think would be good for you.

now, if you had the funds... this is my dream controller... i heard alot about it and i really like the features.

super nice... but can't get myself to buy it yet...

i actually heard different. i use them for my radiators... work great for me? i read that they have higher static pressure then most? what do you mean by your comment? i would like to know.

some numbers i found:

static pressure for Slip Stream 140 mm -

SM1425SL12SL（500rpm） 0.175mm-H2O
SM1425SL12L （800rpm) 0.448mm-H2O
SM1425SL12M （1200rpm) 1.04mm-H2O
SM1425SL12H　(1700rpm) 2.32mm-H2O

if i remember correctly... anythign above 2 is great... the fan i recommended was the 1900 rpm version, so backed down for silence, it will be similar i think...

http://www.overclock.net/air-cooling...ans-112-a.html

if you take a look at that, the scythe 1900 in particular did pretty well... 18th out of all for use on heatsink? i think it looks good... not just for case circulation?

I'm finding they work pretty well in a D14. See item 4 in my post for that. But I'm currently testing fans with the P14 at 12v. The Slip Streams seem to be holding their own quite nicely. It's radiators where you would not want to use them.

For case fans a Slip Stream 800 or 1200 rpm is quite nice. But for them as for all Sleeve Bearing fans, lubricate them before you put them into service, and then again periodically. You will extend their lives enormously, since some of them arrive dry. See item 3 in my sig.

i think... they work great for radiators... but, i only used them with quiet power swiftech radiators. yes, i already got reemed for putting my name so big on the pic... sorry...

That's my intention, indeed.
