The included Enthoo Primo 140mm fans are 3x PH-F140SP_BK & 2x PH-F140SP_BK_BLED in front. Phanteks has the new PWM PH-F140XP_BK with 140mm mounting holes and the PH-F140HP with 120 fan mounting holes in black, white, blue & red that comes on coolers now.. and their original PH-F140TS 140mm cooler fan in black, white, red, orange & blue.
I think there are plenty of 140mm fans that are good for cooler/radiator use, meaning whichever of 420 or 480 will fit is the best choice.
It would take a little more work to find what 140mm fans are good.. and many have 120mm mounts so would need a 120 to 140mm mounting plate/shroud adapter to use on 140mm coolers. Pretty easy to make. Sheet cut to size of radiator with 140mm holes for fans with 120mm holes for mounting fan and 140mm holes for mounting to radiator:
Off he top of my head:
Scythe has Kaze Maru up to 104.5cfm, Slip Stream KazeMaru2 up to 92.4cfm
Thermalright TY-140, 141, 143, 145, 147 fans. The TY-143 is 2500rpm 130cfm.
Silverstone FHp-141 38mm thick 1200rpm 170cfm
Scythe Slip Stream 140XT PWM is 70cfm
Phanteks PH-F140XP PWM is 85cfm
There are Corsair, Noctua, Delta, etc.
CFMs don't mean squat for rads. Look into all of those fans a little harder and you will find that they all (and all other 140mm fans out to date) SUCK at developing high static pressure at lower RPMs / low dBs. And while static pressure won't tell you everything, it is a better indicator than CFM as to how well a fan will handle trying to blow through a restriction such as a radiator. Simply put: There never has, as of yet, been a halfway decent relatively silent 140mm fan for thick rads when compared to the 120mm choices. It's never even been close. That sad fact has been brought up here at OCN and every other site like it a gazillion times now.
The thing is you cannot take the manufacturer's word for it. You have to read the review testing done by folks like martinsliquidlab, just to name one.
I have been waiting to see how the new Phanteks PH-F140SP fans hold up in this regard, as they appear to have been made with this in mind, but no one's going to be sure until reputable comparison testing has been done, and I suspect that's likely to be 6 months from now at best.
Of course, if you're going to do a push-pull you can get by with some pretty decent results with many different makes of 140mm fans at slower/quieter speeds as the fans will work together to help overcome the restriction, or if you don't care all that much about fan noise then the same holds true if you want to crank your fans up. Plus, if you're already going overboard with more raddage than needed, which the Enthoo Primo should provide plenty of opportunity to do, then there's little doubt that you'll be fine cooling-wise with many different 140mm fan/rad combinations, but performance & silent operation-wise, you'll not even really be in the ballpark of what you could have done using most any of the many high static pressure 120mm fans out there.
I guess I could/should add that I threw most of that out the window myself in the end when I went with my fan choice of GeLid UV Blue Wing 120s, as I was for the most part choosing to go with the black & uv blue color-scheme above all else, and then after that selecting the best fans I could find that fit it. If I was purely looking at silent performance on a radiator I'd have went with Gentle Typhoons but I really didn't like the grey color (and I even considered buying GTs and painting/dying the blades). As it is the fans I chose look to be a really good match for the UV Blue acrylic tubing I'll be using, and their performance is better than average as best I can tell. Some reviews rate the GeLid Wing 120s right up there with the best of them, but others more middle-of-the-road. Price-wise they sure weren't 'middle-of-the-road' though, although I did find a comparatively good deal on them so snagged them up while I could.
We all make our product choices based on many other things than performance. Things like looks, cost, expected reliability, brand loyalty, etc all come into play. That's a good thing, or else all of our rigs would be identical.
Round 2 of goodies for my Enthoo Primo build just arrived.
XSPC Razor waterblocks and backplates for my GTX 760s (shame the blocks have to say GTX 670 on them though), A 140mm GeLid for the rear of the case, Primochill UV Blue rigid acrylic tubing, and a 16" UV light stick.
Almost missed the delivery because frozencpu required a signature. I was getting out the shower when the UPS guy came knocking and just happened to look out the window in time to see him driving away. Had to hurry up and get dressed & drive all around for 15 minutes like a madman until I spotted that big brown truck. Good thing too because I have to work the next couple days and wouldn't have been able to get my delivery any other way.
It'll be next week sometime before my next item gets here. I just ordered yesterday another Corsair AX1200 (the only
PSU I even consider buying any more
), then I'll probably take a bit of a break while I finish deciding on mobo/cpu. Might wait on the Rampage IV Black edition & get a 4930k for it, or I might go with an MPower Max & 4770k, or I actually REALLY like the new ASUS X79 Deluxe, all except for those gawdawful gold heatsinks. Damn shame. I might just go ahead and get it anyway and take them off and spray paint them or strip the gold off of them and have them anodized black if I can find a place to do it. Maybe I'll get lucky and someone will make waterblocks for it.
I dunno. Just spitballin at this point. Decisions... Decisions... The longer this Enthoo Primo takes to get here the more I can't make my mind up about much of anything. lolEdited by Unicr0nhunter - 9/25/13 at 12:56pm
