Scythe Ninja Plus Rev. B - The Cutting Edge Cooler

This is the second cooler by Scythe to make an appearance in the roundup. The Ninja Plus Rev. B sports six heatpipes and is rather large, measuring 13.5 x 11 x 14 cm (length x width x height). It also ships with a fan pre-installed, namely Scythe's own SY1225SL12M (120 mm x 25 mm, 1200 RPM, 116.4 m³/h, 24 db(A)).

Scythe Ninja Plus Rev B

The Ninja Plus only receives 4 points for its cooling performance, since it is only able to cool the processor to 77°C even at its highest setting. Due to its configuration using 23 aluminum cooling fins, the fan is about 1 db(A) louder than on the Thermalright IXF-14. At full speed, there is a very audible hiss as a result of this design. Therefore, we recommend setting the fan to run at 75% speed. Overall, its cooling performance is lackluster.

Installation is very simple, as the cooler uses pushpins like those found on Intel's box coolers. Using a 12 cm flat-head screw driver, mounting the fan is child's play. Pushing down or pulling out the pushpins is a bit more difficult without a screwdriver, if there are other components such as the chipset cooler in the way. Holding the cooler is not a pleasant experience, as it has many sharp edges - careless moves can quickly result in injury.

In light of its performance the price of $43 is just acceptable for this cooler.

    I cant believe that photo...sorrii I am with you only a nutjob would use or test it in that configuration!!!
    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.

    Bullshit article.I agree with wkornf.

    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 I can keep my outdated Pentium D under 100 degrees fahrenheit,infact around HALF of these tests,even under water cooling?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.

    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???
    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)

    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.
    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.
