they are 7.0 watters. They move good air and will be replacing the two that came with my MCR220. The only thing I didn't realize was, they are 38mm, not the typical 25mm but o-well.

I buy fans all the time from BG Micro. They used to have a truckload sale where they'd sell you an entire box full of various fans for $20 or so shipped. Those were my fav deals!

Your better off having 120x38mm rad fans, they have a higher pressure and scavenge air through your rad better...Though it would make more of a difference on a thicker higher fin per inch rad...If you don't mind those type of fans, I would look at getting a BIX rad, they are a dual row high performance rad that works well with 100+ cfm fans...360 BIX..Something to think about if you upgrade your rad sometime...

I've been leaning towards the MCR320 primarily because of cost, or adding a 2nd MCR220 for the same reason. I got my MCR220 here from the OP (MNiceGuy) and I couldn't have been more pleased. I don't really NEED the 320 but my brother wants my 220 so I thought why not.

As for the 25 vs 38, I was gonna sandwich my rad between fans but with the 38's, i'm not sure i'll have the room to. I may try it anyhow.

I just ordered 4 of them......On the rad, its just a 360 BIX with the higher cfm fans will give you more bang for the buck, they are a double row high performance rad that thrives on 100+ cfm fans...A 320 Swifty with those fans will still be plenty good cooling on your chip, its all good...

Martin did this thermal testing on them recently..Swiftech MCR320 Thermals-Martin..Its a decent 400W rad with around a 5C rad out to ambient with higher cfm fat fans on it...Your quad at max shouldn't go over 250W OC'ed, so your in good shape...

I've been thinking of moving from my MCR220 to the 320 so I can pass the 220 to my little bro. I may just keep what I have and run with it, we'll see.

Well guys the 2000RPM Ultra Kazes came in the mail today and talk about impressive! I'm dialing them down with a the 6-channel Zalman fan controller (light years ahead of the Rheobus IMO) and while they infringe slightly on what I would call quiet, the move A LOT of air. I did a little comparison vs some fans I have laying around:

--120x25 Cooler Master Blue LED: Even at 11V this moves roughly as much air as a flatulant mosquito. Looks pretty nice though and is dead silent.

--120x25 Antec (non Tri-Cool): It's what's in my sig rig now. Moves more air than the Cooler Master easily but is slightly more noticeable in the sound department.

--120x25 Scythe Slip Stream 1200RPM: Moves a little more air than the Antec and with a little less noise. Nice fan!!

--120x38 Scythe Ultra Kaze 2000RPM. This is a fan!! At roughly 7V this thing feels like it moves more air than the three previous fans put together. Noticeable improvement in pressure as well (by feeling the force it pushed my hand away). At 11V (the Zalman's advertised max), this things move A LOT of air. A touch on the noisy side but tolerable.
