RAIJINTEK TISIS BLACK, Dual-Tower CPU Cooler, 5* 8mm Heat-Pipe, 2*14025mm PWM fans, install 3 fans, Fully Nickel Plating, Copper Base, Multiple Mouting Kit for Intel & AMD

Pros: This heatsink looks great and cools my Xeon x5650 at 3.8GHz very well. I got this on sale and as far as I can tell it performs as well if not better than the Noctua NH-D14. The fans move a surprising amount of air for the level of noise they make, as well as their RPM.

Cons: Challenging to mount until you realize the screwdriver that came in the box is not the right size for the screw heads. Unlike the Noctua NH-D14 fans, these are sleeve bearing, they are still very quiet and seem to be high quality though. While the heatsink itself has adequate clearance the fan sits on top of some ram modules. This is not a huge problem as the fans are mounted with rubber plugs, thus have some play to them, however, can become one if the ram being used has a tall heat spreader on it on it.

Overall Review: Seems like a good semi small company that I will definitely keep on my radar :)

Pros: It keeps my Cpu cool even when maxing out. My cpu used to run just a bit over 70C when playing Crysis 2 in hd mode and now it stays around 42C. When idle the temps are around 18-20C. I do not even have to turn my case fans on high to keep the cpu cool now. It is quieter than what I expected.

Cons: It is huge and is a little difficult to install in a mid-tower case. I had to plug the fans in before installing the heatsink because of the size. I am fortunate that I do not have tall heatsinks on my ram as it does cover all four slots.

Overall Review: I will be keeping my eye out for other products from this company and would definitely recommend this to someone looking for an alternative to liquid cooling.

Pros: -Dual towers, dual fans make it excellent for overclockers -keeps my i5 6600k at a cool 25 degrees C at idle and hasn't gone over 50 while gaming on ultra -Comes with 2 very quite fans

Cons: -The size makes install a challenge to fit in with other components but managed to squeeze it into a Mid tower -It covers up at least 1 or 2 ram slots, I fit my ripjaws 4 under the tower but there's about 3mm clearance and thats in slot 2...slot 1 is most likely unusable. -had to rig it airflow backwards to get it to fit, i.e. the exhaust fan in the back is now intake and the exhaust had to go through the top of the tower....if you rig it the other way the fan makes almost all ram slots unusable. -gets extremely close to your gpu pcie slot ...about 1in clearance...which can be an issue if you plan on using aftermarket cooling on your gpu.

Overall Review: -If you are looking for a water cooling alternative for overclocking this is a sweet machine, but if you are looking to run quad channel it may not be for you

Pros: Great heat dissipation, quiet fans, amazing at its price point

Cons: Very large, had to mount it vertically to get the ram clearance I needed, also had to switch cases

Overall Review: Would definitely buy again, it works great, very effective at 150watt+

Overall Review: very good
