Foxconn NBT-CMI7759B C - The Design Snafu
You can see at a glance that the NBT-CMI7759B C made by motherboard manufacturer Foxconn is almost identical to the classic box cooler that comes with Intel processors. This is the high-performance version of that design, using a large copper core and fine aluminum cooling fins.

The noise generated by this model is also identical to that of the box cooler, and the two also share the automatic fan speed regulation feature (PWM).
At 86°C, cooling performance is also on par with that of the box cooler. When idle, the fan is barely audible from within the closed computer case.
That begs the question: who needs this cooler? The price gives us an answer, really. Costing just shy of $13, this is the ideal replacement should the box cooler fail, for example if the push-pins break off.
Since the fan conceals the push-pins, these can't simply be released using a screwdriver. Apparently, someone missed this fundamental design snafu during the QA process. In the worst case, users may be unable to remove the cooler from the board, if it is mounted in a cramped case.

Thank you, been wondering what cooler to buy for an OCed Quad, and high temps are good when dying :DReply
... must be stupid ...! The fan is istalled at wrong side of the cooler ...Reply
Thermalright FTW!! Every time.Reply
I cant believe that photo...sorrii I am with you only a nutjob would use or test it in that configuration!!!Reply
Noctua clearly state orientation of their coolers and that is ass about.
Every other review I have read rates the NH-U12F much more highly... always near best in class
your numbers of near 70C on every cooler is outrageous, if those numbers are true not a single one of these coolers would keep a computer stable in a closed case outside the northeast. and a couple minutes isnt a good measure of cpus final temp, if u look over a temp log after a long game session you know it creeps up. to many factors.Reply
Bullshit article.I agree with wkornf.Reply
If my Artic silver 5 + Scythe Katana 2 cooler(for only a massive price of 25 USD! I can keep my outdated Pentium D under 100 degrees fahrenheit,infact around HALF of these tests,even under water cooling? Wow,according to this,I should actually worry about getting a quad core because of the heat.And no,I don't have any fans in my case,it's open,only fans are from my GPU,CPU,and my PSU.
No extra 4 250mm performance fans.And an X38? That's just unbelievable.
Do you guys get the point? They maxed out everything, so the cooler could show off the best that it could do in the most extreme conditions.Reply
A good article, i especially like the tests for installation and sound, as those are what i would look into most when purchasing a cooler, and unlike CPUs, there are usually no charts to go along with.
eaglestrike... do you see mounting the noctua fan in the wrong direction as good testing???Reply
They have it on the top side of the sink flowing in a downward direction!!!
it goes against basic laws of physics and logic.
alot of the coolers listed of a particular design are installed all goofy like, Of course on their open setup it doesn't make much difference(i think)Reply
but when installed in a normal ATX case, would be detrimental to the coolers performance. Especially coolers designed similar to the Noctua and Scythe Ninja plus.
I can't be certain about others but Arctic Cooling's Freezer 7 Pro is supposed to be installed like this(one would assume others of similar design would be the same)
cliffro I think to some degree you are correct but it still does not follow good practice when supposedly collecting data to represent consumer products.Reply
As these have published manufacturer recomended installations why would you reverse it.
I recently read a review of the latest Noctua cooler at Legitreviews
where Noctua actually contacted them on this very issue... as a result they retested and found some improvement in cooling.
