Simple fan screws work as well. If you have a 6-32 x 1cm it will fit inbetween the holes on the shroud and still have enough depth to secure it to the rad. Then you attach the fan to the shroud using fan screws. Thats what I'm doing for my Ultra Kaze.
Oh and here are some fan speed comparisons:
My H50 is currently set up on the rear 120mm slot as follows:
Ultra Kaze 3000 | Shroud | Case | H50 | Noctua NF-P12-1300
Both fans are intake
I'm running Prime95 blend, and the loop is warmed up.
Ultra Kaze : OFF
Ultra Kaze: ~6V (as low as it can go before turning off)
Ultra Kaze: 12V (100%)
With the UK off my rig is pretty damn silent, when its at 6V, its somewhat noticeable, but only I'm not watching something/gaming/listening to music. At 12V its painfully noticeable, but I can't hear it when I have the fan on in my room.
With just my pathetic little Noctua, running at 65% sucking air in through the rad, case grill and the stationary UK, my H50 still manages to keep the temps in check under load. Tcase as reported by the motherboard was 65C, which is still 7C under the limit. With the UK going at 6V Tcase was just 56C, giving me plenty of OC headroom should I need it.
Thats the magic of the H50. Keeping a 3.8GHz i5 750 at acceptable temps using a single undervolted Noctua fan outputting less than 30 CFM is pretty much impossible on the VenX, Megahalems, and pretty much any other tower heatsink you can buy. I actually got worse temps using the exact same fan with an HDT-S1283 on my tiny little e5200.Edited by nathris - 4/16/10 at 10:14pm
