Scythe Tatsumi CPU Cooler Review

August 20th, 2014 Mike Leave a comment Go to comments



Going back a few years and back to my very first Gaming rig build, the CPU coolers of choice came from the likes of Titan, Arctic, Tuniq, Noctua and of course Scythe. I probably spent the best part of six months choosing which components to spend my hard earned cash on, but finally settled on the rather good the Scythe Mugen (I also made the bad decision of an XFX Nvidia 7950 GX2, but I’ll save that story for another day…). Oddly since then I’ve never had the opportunity to look at any other Scythe hardware until now. So here we have the Scythe Tatsumi (SCTTM-1000B), which in many ways looks similar to its much older sibling (at least in appearance and from a distance). So what do we know about this CPU cooler?

The Scythe Tatsumi is an entry-level CPU cooler, which measures 102mm(W) x 83mm(D) x 146mm(H) and weighs in at 450g. The Tatsumi features a tower-type heatsink with three 6mm thick copper heat pipes conveying heat drawn from a nickel-plated copper base, to an aluminium fin stack which is ventilated by a 92mm PWM controllable fan. The fan spins at speeds ranging between 200 and 2,500RPM, pushing between 6.7 and 55.55 CFM of air, with noise output ranging between 7.2 and 31.07dBA. Amonst the CPU socket types supported are LGA2011, LGA115x, LGA1366, AM3(+), and FM2(+).


Scythe ‘With the Tatsumi, Scythe throws on the market a cooler compatible to a large number of sockets while being gentle on the budget, neither compromising on built-quality nor performance. The Tatsumi as well sports the highly efficient M.A.P.S.-fin structure to optimally make us of the cool airflow and minimize windage. The mounting system, borrowed from the Kotetsu, guarantees easy and secure mounting after undergoing a few adjustments. Accompanying the Tatsumi is a PWM-fan taking care of the quiet cooling operation. Compact dimensions with a max height of 146 mm let the Tatsumi find a home in nearly every type of PC case.’


So it’s small, light, quiet and compatible with almost everything under the sun, but probably not deserving of a place in a performance Gaming PC…….

Or is it? 😉

The front of this small box is predominantly white and purple (yep purple!). It shows an angled image of the Tatsumi itself, its name and model number, the Scythe logo, that it’s socket 1150 ready and has a small picture of the cooler base.

The back looks incredibly busy, but more or less just shows the CPU cooler warranty in several languages.

I realise this is only a box and not to everyones taste, but in my eyes it has that typical Japanese pop culture style, which I rather like.

The left side is predominantly purple and shows us a technical drawing of the Tatsumi and gives us the specifications.

The top shows another photo of the CPU cooler, tells us the box also contains an installation guide and thermal grease, then shows off a few awards (if they were all on show, they’d need a bigger box!).

The right gives us the key features of the Tatsumi as follows:

  • H.P.M.S (Hyper Precision Mounting System)
    The Hyper Precision Mounting System allows high secured mounting with easy and straight forward installation.

  • M.A.P.S (Multiple Airflow Pass-through Structure)
    Three dimesional Multiple Airflow Pass-through Structure applied for maximum use of airflow.

  • Narrow Fin
  • 92mm PWM Fan
  • Wide Range Cooling Purposes
  • Optimum performance is achieved in a wide range from low to high RPM.

    Popping open the small box shows us there is a hell of a lot squeezed into such a tiny space. It also reveals the Scythe Tatsumi in the flesh.

    So tipping (carefully of course) it out on the desk, what do we find inside?

    Optimized Cooling Performance
    The unique arrangement of the cooling fins (M.A.P.S. – cooling Fin Structure) combined with the special finish of the base plate make the Tatsumi a great performing cooler. Airflow is hardly meeting any resistance, resulting in a quiet and efficient cooling operation.

    Multi Fan Mount Structure
    The shape of the Tatsumi allows mounting it in two different positions, faciliating the set-up of a directed airflow. Also given is the possibility of mounting a second fan for increased performance (fan has to be purchased separately).

    Easy Mounting
    The H.P.M.S. (Hyper Precision Mounting System) takes care of quick and secure mounting of the cooler. It is now possible to dismount the heatsink without having to remove the mainboard.

    Compact Dimensions
    A lot of time was invested to find the perfect balance between the cooling area and the dimensions of the heatsink when developing the Tatsumi. The result is a cooler fitting into cases with rather limited space without compromising performance.

    High Hardware Compatibility
    The arrangement of the cooling fins coupled with the dimensions of the heatsink allows the users to choose both their mainboards and memory modules at discretion. Even memory modules or VRMs with unwelcoming heatsink structures will not get in the way when mounting the Tatsumi.

    First Impressions


    Scythe Tatsumi - Front Scythe Tatsumi - Side


    Now the Tatsumi is out of its box we get a chance to take a proper look and wow it’s small. At 102mm(W) x 83mm(D) x 146mm(H) it is probably the smallest CPU cooler I’ve ever laid hands on, so should fit in almost any case too.

    My second thought was how solid it is, I honestly believe if I were to accidentally drop it, it’d be the floor that would come out second best! The build quality is really that good. Although it most likely won’t win any awards with its looks.

    From the front and side, we can easily see the three 6mm copper heat pipes running through the copper base and incredibly dense aluminium fin stack (coined M.A.P.S or Multiple Airflow Pass-through Structure by Scythe). Of course when set in place and installed in your Gaming rig, you’re unlikely to see this. Taking a look from the side shows the Tatsumi fan stack is slightly staggered to allow the use of any RAM modules of any size.


    Scythe Tatsumi - Top Scythe Tatsumi - Bottom


    From the top (the bit you’ll see the most of), we see a large (at 102mm x 83mm it isn’t actually large at all, but the largest noticeable part) aluminium fin with the Scythe logo embossed in the dead centre. We can also see the signature Scythe heat pipe caps, which I’m told are there to help dissipate heat.

    Underneath we get to see a highly polished nickel-plated copper base which is protected from scratches by a plastic sticker (heed to clear warning and remove before installation! 😉 ).


    Scythe Tatsumi - Angled Scythe Tatsumi - Front with Fan Scythe Tatsumi - Angled Right


    Having a quick look at the Scythe Tatsumi pre-assembled and un-installed shows that the diminutive little CPU cooler doesn’t look bad at all. Perhaps the only grievance I have is the multi-coloured cable running from the 92mm PWM fan, it’s only a small touch, but it would’ve been nice if this was sleeved or in the very least all one colour.

    Scythe Tatsumi - Installed


    The Scythe Tatsumi CPU cooler being compatible with many different CPUs, has many fixtures and fittings, so the first order of the day was to simply sort out what was actually needed.
    Now that’s sorted it allows us to crack on. First up is the backplate. Once this is has the correct screw holes lined up with the motherboard, a nylon washer is placed on a metal stand off which is then screwed through the motherboard and into the backplate (this is obviously done four times 😉 ). The appropriate Intel mounting plates are then screwed to the stand offs. Thermal paste applied to the CPU and squished down with the Tatsumi, the mounting bar is then fed between the cooler heat pipes and attached to the mounting plates. In fact I make it sound a damn site more complicated than it actually is! 😉
    Once the Tatsumi is secured, it’s time to install the 92mm fan. Scythe have chosen to go for the fan clip approach which works well if a little fiddly (personally I’m not a big fan of this and would much rather see anti-vibration rubber mounts instead), then plug it into the motherboard CPU1 header. Job done.

    The Scythe H.P.M.S (Hyper Precision Mounting Sysytem) makes installing the Tatsumi incredibly easy and surprisingly quick! This is obviously a big plus for anyone wanting a new CPU cooler, but as you can see in the photo above, it is rather small and if I’m honest I don’t have high hopes in its ability in cooling an overclocked i5-4670k….

    So lets take a look!


    Testing Methodology/Setup


    For CPU Cooler testing, we here at pcGameware run Prime95 for a 15 minute period. During this period the temperature is monitored with CoreTemp and the cooling performance recorded (the max recorded is the average for all cores). Between each stress test we allow a 15 minute cool-down to allow for more accurate results. To help with fan speed accuracy we use SpeedFan whilst using MSI Command Center to adjust the fan speed. A close eye is also kept on the ambient temperature, with the maximum being recorded for each run, this allows us to calculate the Delta temperature (Core – Ambient = Delta). Each run was performed with the Intel Core i5-4670K CPU at the following frequencies: 3.4GHz (Stock), 4.0GHz (using MSI OC Genie, shown in the picture below) and 4.5GHz (using Intel XTU(Extreme Tuning Utility), also shown in the pictures below), all results have been recorded with CPU-Z.

    * Please note: To ascertain the maximum and minimum noise levels produced by our CPU test coolers. The db is recorded with all case fans unplugged to isolate the sound in question.

    Hardware Performance


    To make our performance tests easier to follow and to get the most accurate recordings, all of the following tests have been carried out with case fans set at 100% and the Scythe Tatsumi 92mm 2500rpm (±10%) also set at 100%.

    Raijintek Themis 100% 19.00 60.75 41.75 47db


    Now there’s a bit of a surprise….. The results from the Prime95 stress tests show the Scythe Tatsumi to be the best air cooler and second best cooler we’ve tested with the current Test Rig so far! It knocks spots off the Raijintek Themis and at 49.75C beats the Cooler Master Nepton 280L by 5C, better still with a noise level of 32db it’s barely audible.

    Of course this is all at the i5 4670K stock speed of 3.4GHz, so lets take a look at how it performs with a little OC.


    • Intel Core i5-4670K – 4.0GHz (OC Genie)


    Cooler Master Nepton 280L - Prime95 - 4.0GHz  (fans @ 100%)

    Scythe Tatsumi – Prime95 – 4.0GHz (fans @ 100%)


    CPU Cooler Fan Speed Ambient Temperature Max CPU Temperature (core average) Delta Temperature Noise Level
    Cooler Master Nepton 280L 100% 18.00 59.00 41.00 67db

    Scythe Tatsumi 100% 24.00 72.75 48.75 32db


    Now this is more like I was expecting. The Scythe Tatsumi is firmly at the bottom of our chart with a small overclock of 4.0GHz. Although it is nearly 5C higher than the Themis with 72.75C, the temperature is still not something to worry about for a stress test benchmark and certainly not for day to day use. Clearly the noise level is still the same at 35db and personally I’d be very happy with the trade off.

    Can it cope with a slightly higher overclock?

    Scythe Tatsumi 100% 24.50 77.25 52.75 32db


    I must admit my surprise again. I didn’t think this little CPU cooler to be capable with a higher overclock, but with the i5 4670k set at 4.5GHz, the maximum temperature recorded as an average over all four cores was 77.25C. Given its size this is phenomenal.

    Of course if this is still a little toasty for you it’s worth bearing in mind that while Prime95 is an excellent tool for testing the stability of any CPU overclock, it does this by running your CPU at 100%, in your average Gaming session you’ll most likely not even use half that. 😉


    Final Thoughts


    Here we have the Scythe Tatsumi CPU cooler. It arrived fairly well packaged in a very Japanese pop art styled, tiny box which gave off a pretty good idea at the diminutive size of the cooler inside. The packaging and fitting guide were clear and concise showing the Tatsumi to be compatible with very nearly every socket type under the sun.

    Once out of the box, the Tatsumi really shows how small it is (102mm(W) x 83mm(D) x 146mm(H)), yet still fairly heavy (450g), although it is easy to see where the weight hides with its three heat pipes and incredibly dense M.A.P.S (Multiple Airflow Pass-through Structure) fin stack (perhaps it’s wrong to call the cooler small when compact is more apt??). Despite it’s size, the Scythe Tatsumi has an incredibly high build quality, the cooler has no flex in the fins and is built like a tank. Although granted it won’t win awards for its looks. My only real gripe is the multi-coloured cable running from the 92mm PWM fan, it would’ve been nice if this had been sleeved or in the very least all one colour.

    Very surprisingly (to me at least). The Scythe Tatsumi performed admirably throughout our Prime95 stress tests with an incredibly low 49.75C average core temperature when the i5 4670k sat at its 3.4GHz stock speed, rising to 77.25C when the CPU was overclocked to 4.5GHz. Given its compact size, this is certainly impressive, but what makes it more impressive still is the maximum noise the fan produced at full speed (32db!).

    Taking all into account, the Scythe Tatsumi turns out to be an impressive little bit of kit. It’s compact, near silent, can handle the heat produced by overclocking and well priced at approximately £25.00. It’s pretty difficult not to recommend.

    So there you have it, the Scythe Tatsumi, the little cooler that can!
