Up Close

The Noctua boxes a subtle and understated and really do have a feel of quality about them.  Just look at the accessories box you get with the NH-D9L.  Everything inside is laid out all neat and tidy and easy to find.

Now don't go thinking this is a massive twin stack cooler, because it isn't.  That there fan in the middle is actullay just a 92mm unit, which puts the height of the entire shooting match at just 110mm.  You'd also think a 2000rpm 92mm fan would whine like a Welsh farmer who's allergic to wool, but at just 22.8dB(A) it's actually not too bad.

The pipe ends aren't capped, which is a shame because we think it would help finish the elegant look of the cooler off.

We think this is one of the fastest and easiest coolers we're ever fitted, the SecuFirm2 system really is excellent, and the performance isn't bad either, although we did expect it to better the single stack NH-U9s it wasn't behind it by much.

Had a quick look..
dont see any AIO's in there as a comparison.. I think it would have been nice to see atleast 1-2 of the most popular ones in there, it would just round out the comparisons a bit better imo if you also factor noise efficiency and redundancy.Quote

Great article, good to see my D15 is still a beast in the air cooled department.

One small thing, while reading the D15 page I couldn't help but notice something wrong.

With the front fan installed you are though limited to standard height RAM.
This is actually not the case, the fan can be positioned forward due to the design of the mounting which allows for big RAM if you have the case clearance for the fan to protrude off the cooler.Quote

That explains all the hype around the Cryorig lot, good prices and performance there. Great to see so many all together in one place for comparison.Quote

The BeQuiet coolers are meant to be tightened from the back of the motherboard, not above and between the fins. No wonder you found it hard to do.. If you are saying that poor fitting is the reason they don't perform well, then the test results are not representative of the coolers performance.Quote

I bought the Be Quiet Dark Rock TF for the looks for the Lian Li Q10 build - was supriced that it placed so low.

Have the Raijintek Pallas on my living room rig cooling a G3258 and I thought it was great.Quote
