A10-7850K build on hold due to missing NM-A90 bracket kit

Pros: I've standardized on Noctua for excellent cooling and build quality but their logistics failed me this time.
Cons: Bought this fan for a small form factor build with Kaveri A10-7850K and Gigabyte GA-F2A88XN-WIFI mITX motherboard. Although it states that it's compatible with FM2+ socket it's missing a bracket kit to allow cooler orientation for optimal front to rear case air flow. Without the bracket air flow is non-optimally sideways or up-down. So, my build is on hold for up to 14 days for the NM-A90 kit to ship to me from Noctua. They should bundle this bracket kit with the fan ...
Summary: Note that I am an extremely happy owner of several Noctua products. I ordered this cooler for a friend who is running an AMD Phenom II X6 1090T on a Gigabyte GA-990FXA-UD5 socket AM3+ motherboard. Upon installation, we found that the cooler would only install in such a way that airflow would be oriented vertically. That is, it would move air from the bottom of the case up, or the top down, not from front to back.
Nice cooler, but why no PWM fans and no fan grills?

Summary: This is a decent heat sink. It was one of the best vertical heat sinks I could fit into the RPC-4216 4U rack-mountable case I bought. Since the other reviews focus on the positives, I'll only focus on the negatives: 1. No 92mm metal fan grills. This means on most socket 1155 motherboards the PSU cords could touch the fan. This is a big issue and design flaw. Why not include the $.50 92mm fan grill? 2. The instructions never mentioned socket 1155, only 1156.
Summary: It's also not that attractive, but I knew that from looking at the pictures. Comes with a neat little owl sticker.
Pros: Keeps things cool. Quiet. ultra low noise, low noise or normal options. Assembly/instructions done well. Comes with thermal compound.
Cons: The metal clips on it block 1 RAM slow (using Ripjaw), like many have mentioned. If you are mounting on AM3 socket the only directions of air flow available is top to bottom/ bottom to top. You can NOT have the CPU fans vent out the rear fan. You have to vent it out the top or blow it down towards your PCI slots. This is a pretty big oversight since its standard to vent out the top back.
Summary: Why couldn't they include PWM fans? I replaced the stock Noctua fans with Artic Cooling F9 PWM fans and my system is finally quiet again. PWM feature allows the motherboard to increase fan speed based on CPU temperature. The stock Noctua fans run at the same speed regardless of temperature, a step backwards in cooling design if you ask me.
Pros: Keeps CPU cool, between 20-44C (idle-load) for i7-2600k using ULNA fan adapters in 2 fan push/pull config. Compact height fits well in smaller cases, I'm using Lian Li PC-V354B and rear fan has about 1/4-1/2" clearance between top of fan and power supply.
Cons: Noisy fans, even using ULNA. Mine has a slight clicking noise even at low speed. Fans are 3-pin, not 4-pin PWM - ended up purchasing PWM fans Had to bend fan brackets to accommodate RAM (using ASUS Maximus Gene-Z/GEN3 and Gskill Ripjaws X)
Summary: I purchased a GIGABYTE GA-990XA-UD3 AM3+ Motherboard and 4 sticks of G.SKILL Ripjaws Series 16GB (4 x 4GB) RAM but quickly realized that all 4 sticks cannot be used because the Noctua mounting clips block the first slot. While I was able to improvise by substituting the clip with a plastic cable tie which was threaded through fan mounting holes (I'm using one fan) and heat sink, I'm of the view that Noctua should have foresaw the possibility that the clips along with a...
Pros: This is a follow-up to my 1/30/2012 review. So far this fan is doing a nice job, but:
Cons: Mounting clips obstruct first (blue) memory slot on my GIGABYTE GA-990XA-UD3 AM3+ Motherboard. The problem cannot be overcome by bending/compressing the clips. You either improvise by using another way to mount the fan(s) or don't use all four slots. Airflow is up and down instead of horizontal and there isn't a way to change mounting so clips don't interfere with the first memory slot.
Summary: I thought all CPU fans would be 4pin with PWM? All my other CPU coolers have changing fan speeds which is really great because they stay usually stay very quiet at ~600rpm until you do something intensive with the CPU and then they run up the speed to 1000+rpms. This cooler can only run at a set speed which is actually kind of noisy! I hear the cpu cooler fans running over the rest of the fans in my rig. I'd get another cooler with PWM if it will fit in your case.
Pros: Fits in my LianLi v354 on Asus Maximus IV-Gene, two fans,
Cons: the fans are not PWM so the motherboard can't adjust the fan speeds according to CPU temps
