I'm looking at getting the Cooler Master SickleFlow 120 2000 RPM 120mm Blue LED or the Enermax UCTB12N-BL T.B.SILENCE 120mm Blue LED fan for removing heat off my radiators.

However, I can't seem to find any details on the connector type. Need 3 pin for it to run with a fan controller. Would anyone happen to know the connection type on them?

And what are peoples opinion on the two fans? I heard the Enermax one gets loud when put up to max speed.

Yeah, but all places that sell them are sold out sadly. And they cost a pretty penny. What out of the two I listed would you recommend?

The CM Sickleflows would be my choice between the two. They have higher airflow at a lower cost, though they are accomplishing this simply by spinning fast. In terms of build quality, the Enermax fans probably are better made; however, I have read complaints about the Enermax fans being loud, sometimes very loud, and that isn't something I usually associate directly with quality. The CMs are cheap enough you could buy a couple and afford to not like them and then just use them in something else.

Would you happen to know the dB-A of the sickleflows? Everywhere list them as "19 dB-A" which I find highly unlikely at 2000RPM.

Puget did a review on them. By running the fan at 12v, which is pretty high, they got it up to 46.4 db. For reference, your startup cycle is something like 9v, most likely. 7v is pretty normal for a system while running.

Would Scythe Slip Stream (1200RPM or 1900RPM) be a good choice for pushing air through a rad? They seem to have a decent balance between sound and rpm/flow.

I don't think it would be any better or worse than most other fans. They have very high airflow, but from what I know of them, they don't have much for static pressure, which isn't ideal for using them with a radiator. The problem is going to be finding them as last I knew they had been discontinued. Again, the absolute best fan for working with radiators are the SP120s and it's unfortunate that they aren't available where you are at. I know that stateside, you can always get them. I literally keep a pack of them lying around.

I have actually just found a place with two packs of twin High performance editions. May order them.

Yeah, don't buy them one at a time. They are like $18 US for a single fan here or $27 for a pack of two. $13.50 a fan isn't cheap, but $18 is insane. Unless you have major concerns about noise, get the High Performance edition. I am sitting next to four of them right now and they aren't particularly loud. I don't know the exact db at load off the top of my head.

Anyway, good luck and I hope the fans work well for you.

I'm a bit ambivalent about Cooler Master Sickleflows. For their price point, they seem like an excellent fan. I stay away from them, because I know that they have a standards Sleeve bearing, so horizontal mounting leads to suboptimal (acoustic) performance and shortened lifespan.

If you really really want the blue LED, that Enermax fan will do, but that 1200 RPM can be limiting. (With standard use, most fans won't go too much over 1200 RPM, so the limitation isn't that bad.)

There are also these: http://www.newegg.com/Product/Product.aspx?Item=N82E16835233105 which may fit the bill nicely.

My top recommendation would be these: http://www.newegg.com/Product/Product.aspx?Item=N82E16835553012 I'd wait until they can down to $15 dollars, however.
