Scythe Katana 3 Quiet CPU Cooler

- Replaces the Scythe Katana 2 Heatpipe Quiet CPU Cooler- Replaced by the Scythe Katana 4 Quiet CPU Cooler

The word Katana is not only a name for a famous Japanese samurai sword but also for the well-known cooler series by Scythe. The Katana 3 presents a cooler which is based on technologies that have been developed and optimised over many years. Due to the slightly curved structure of the Katana 3, the virtually-silent 92mm PWM fan is not only used for the removal of heat from the CPU but also to cool down sensitive components on the motherboard.

Tool free installation

The smart and patent-pending mounting mechanism "VTMS" (Versatile Tool-Free Multiplatform System) allows mounting of Katana 3 CPU heatsink without using any tools.

S.P.S. (Slant Pipe Structure)

Already developed with the first Katana, the slightly curved shape of the Katana 3 allows both the direct heat transfer from the cooling fins of the cooler as well as an additional cooling of the motherboard components.

F.P.S. (Fast-Phase Structure)

The various cooling fins on the baseplate allow for additional heat dissipation and optimise the overall performance of the cooler without changing the compact dimensions of the entire system.

Scythe Katana 3


What a great product why didn't I know about this before. The team at Quiet PC are really helpful & the delivery was super fast.

Good choice for lower power AMDs


Works fine with AMD Athlon II x2 250. Quiet & Cool. No problems with fitting. For higher wattage AMD's consider a Mugen.

cool and quiet mods


I've really got too tell what I've done to this very good cooler cos it works so well. OK Phenom II 3.2 x2 unlocked =x4, no oc'ing cos I don't need it, this cooler with a 90 -120 adapter (80 - 120 but cut down) then put a Noctua 140 fan on it. I'm using Asus pro Q fan and the idle temp of 27 summer and max temp of 36. It's a sub 16dB PC and takes up very little space. Works well with 120 fan as well. The original fan is great on lower spec CPU but when you go to multi core the RPM picks up and becomes too loud for me. I've a range of products from different manufacturers and Scythe isn't bad at all. Shush and be cool.

Scythe Katana 3 Quiet CPU Cooler


Contacted Quiet PC with regards CPU Cooler. My e-mail enquiry was responded to within the hour. Andy recommended the Scythe Katana 3. Ordered and was on my doorstep within 24 hours. Great product- has really quietened my PC. A little tricky to fit due to space restriction under the fan, that's why it only gets 9/10 instead of 10/10. Great overall service form Quiet PC

Excellent Cooler


For the price this is an excellent CPU cooler and copper heat pipes always make a difference. Misses out on a 10/10 for two reasons, for one the angle of the fan means that it can interfere with the first PCI or memory slot. Secondly the clips for installing on Intel sockets are directly underneath the fan making it more than a little fiddly!

Having said that once fitted I was very happy with the product - it keeps my new i5 at 30 C idle and <50 C under load.

Excellent performance at low cost


As noted by Tom, installation is a real fiddle - in my case (LGA 775 socket on ASUS P5Q-E) because the two push-pins under the fan side of the cooler are totally obscured to access from above. Instead, I had to move a lot of cabling plus RAM to squeeze my fingers in from the side!

Once completed, the fixing is secure and it was good to see that, unlike the stock Intel heat sink, this cooler's pad face completely covers the processor! Temp dropped 12deg C at idle and 8 deg C under load. The Scythe fan isn't much quieter than stock at max rpm. However, the cooler now doesn't need a fast fan speed - mine runs at ~800rpm to deliver 25 deg C at idle and 34 under load. My CPU TDP is 65w so this cooler is probably capable of being used passively...however I prefer to have some cooling breeze for the surrounding components.

Kit contains sachet of thermal paste too. Excellent value; well packed and speedy despatch. Thanks to Quiet PC for suggesting this economical cooler.
