Absolutely superb... The cooler I've been looking for.

I've been in search for a near silent setup recently as my PC is in my bedroom and on 24/7.

Gone are my days of overclocking (although I think this cooler could keep up with OCing too) - silence was my goal.

My Core 2 Quad (Q8400) is getting a bit old now. I replaced the stock cooler on purchase with an Arctic Cooling Freezer Pro Rev 2. This kept it cool under load but wasn't the quietest of coolers and was on its way out.

I looked at a NoFan cooler and case, but the size coupled with my off-centre Asus P5Q Deluxe motherboard meant it wouldn't fit. Second attempt was a Be Quiet Dark Rock 2. That thing was enormous. Too tall for a "standard" tower case.

The P5Q, aside from the off-centre motherboard also has cooling fins surrounding the CPU, meaning space and clearance is the biggest concern.

And then along comes this Noctua NH-U9B SE2.

I bought it because of the size and claimed noise levels and wow, it delivers!

Installation was fine if you're comfortable with taking your mobo out. Always a good excuse for a bit of an air dusting and cable tidying anyway!

This requires a backplate which is as simple as screwing through the existing holes on the mobo to the mount. After that, it's just a case of sticking on the top mounts, applying the supplied thermal paste, plonking it on top and screwing it down. The 2 fans are small and the clearance was fine for fairly tall RAM and all the fins on the board.

Only downside is that they aren't PWM fans, but then with 2 of them, and the low noise, having them running at full speed is a must anyway.

Fans clip on easily, and then you're done. A quick rebuild and well, you CANNOT hear this thing. ULNA adapter for me is just fine - computer idles around 17-19c and under mild load only gets up to about 25c. Not tried under heavy load, but am convinced this will keep my CPU cool.

I've added a fan controller for my aftermarket GPU cooler and now the only thing I can hear is my NAS, which isn't excactly loud.

I'd highly recommend this to anyone with space issues in their build where noise and performance are the biggest concerns.

I don't doubt you can run this on a newer OCd machine either - just switch out the ULNA adapater. These fans are quiet without it anyway!

Excellent product, excellent build quality - superb!

A very good CPU heatsink. It's really quiet, fairly small, and it keeps my CPU extremely cool. Currently my CPU temperature is between 10 and 20 degrees celsius. I'm using an AMD FX-8350 at 4GHz. There's easily room to overclock it in the future though, thanks to this cooler.
The reason I've given this 4 stars is because, if you have an AMD CPU, you can only mount the heatsink vertically - i.e. pulling air from the top of the case and blowing onto the graphics card, or vice versa. I'd have liked to mount it the other way round, personally.
It still works very well as a CPU heatsink, no matter which way round you have it mounted.

Awesome silent

Barely noticeable, so silent! and I'm not even using the noise reduction stuff that comes in the box.
Well, My i5 3570K sits at 36-47°C at 80% load with little OC @4Ghz, I'm very very happy with this purchase.

Make sure you select low profile RAM if you are willing to fill all your slots since this baby is huge and
you can't fit a tall corsair vengeance module there. To achieve it you would need to change the heatsink orientation from horizontal
to vertical. Remember this will change the airflow as well, but that way your last memory module will fit.
Anyways this depends on the motherboard design, RAM modules location,etc..
I noticed this when assembling my GAZ77X-D3H, but since I'm only populating 2 slots, 1 and 3, no problem at all.
The slot 4 is the unreachable one with high profile memory since the NH-U9B SE2 covers it completely.

Noctua NH-U9B :(

I am sure this would have been a excellent CPU cooler (I have a Noctua NH-U12S in my other computer) but unfortunately it would not fit into my system, the back plate is to thick to fit between the motherboard and the case, if the cut-out on the case had been a little higher up or the cpu on the motherboard a little lower down then it would have been OK. I did think about removing the padding on the plate (and applying thinner padding) to get it to fit but was unsure as to whether this would affect the cooler installation so in the end had to return it.

CPU = Intel Socket LGA 775
Motherboard = Asus P5N-E SLI
Case = Cooler Master CM Storm Scout 2

Very high quality

Very quiet work. Very high quality. Cools very well. Value for money is excellent. Noctua NH-U 9B 775/AM2/AM2 SE2, NH-U_9B_SE2 actually made ​​in Europe.

Silent and Cool, but...

The build was straight forward apart from 2 things.

The plastic strips: it stated I should have 4, I only had 1, but the thing was I had to kind of rip them into 4 pieces.

The thin metal brackets: the method of using these to hold the 2 fans to the heat sink was really not clear, you don't put it through the holes of the fan's corners. You have to stretch them and land the last bend into the hole in the corner; when the fan was already in place. -Had to youtube it for that.

It's a good cooler, the only sound you will get is from your case fans. playing the latest games I have seen a reduction of about 25'c at the most.

But as someone else has stated, it's bad that the air gets blown onto your graphics card, but its nothing to worry about, temperatures are great.

Overall I do recommend this, silent and cool :)

Just about fit in my BitFenix Prodigy case alongside a GTX 670 FTW Sig 2 GPU. Runs very cool as well.

Despite it being excellent, a star lost for the following minor issues:
- No PWM fans included. I replaced the non-variable fans with 2x PWM Noctua 92mm fans I also bought here. Expensive but necessary.
- The metal bracket used to secure the fans slightly protrudes over the PCI-E slot, meaning there is unnecessary pressure against my graphics card. I have the Gigabyte Z77 Mini-ITX board, which the Noctua site states is fully compatible with this cooler. Not quite.

The positives greatly outweigh the negatives though, even the Noctua thermal paste is excellent. On par with the MX-4 I originally planned to use.

Great cooler!

I wanted something to keep my i5 nice and cool but didn't want to break the bank. Turns out this was perfect for the job.

Its not much quieter than the intel stock cooler but it sounds a lot smoother (Also I didn't use the low voltage fan cables included so this might have something to do with it...).

The only real reason that i had to upgrade was that the stock cooler struggled to keep the cpu at a temperature that I would be happy with during gaming or video rendering. The stock cooler used to run at around 30 degrees idle and 70 while under load, this runs at 17 idle and 55 ish under load. So overall a good investment.

I dismantled my whole tower only to find that I didn't really need to but you will have to if you don't have a cpu cut-out.

It fits onto the 1155 platform very well, thats one thing that I couldn't find out while researching this cooler so I hope that helps.

Overall a great purchase that I would really recommend.

Bought this to replace woeful i5 3570k stock cooler, and my old stock cooler didnt fit my new intel board( cant get over how rubbish the stock cooler is, as it's loud and not very good at cooling, but that's another matter ).

Bit confusing as a noob to assemble, with my main issue coming with figuring out the clips to attach fans to heatskink, and the instructions arent crystal clear by any means.

My only real other gripes with this are the fact it runs off two wires for fans, which means you have to try find way to hide these to avoid ruing air flow, which isnt easiest of feats.

Even at highest RPM, these are quiet, and with my other fans in case(I dont have vast amounts. 2 mediocre 120 mm at front, and 2 decent 120 mm at top, and obviously an exhaust fan) and this thing keeps my case like an icebox. My temps with stock were highly variable, and could go upto early 40's and higher under no load at all, but with this it sits at 30-32 or lower under no load.

It's so effective, I'm tempted to buy some 140mm Noctua fans to replace my top fans, as they make more noise than my heatsink fans by a long distance
