As you have read, the opinions are rather wide insofar as selection.
All the tower coolers have superior cooling abilities, along with the BT and the Zalman 9500 or 9700.
Essentially you have about 5 to choose from.
- Tuniq Tower
- scythe Ninja
- Noctua 120
- Zalman - 9500 / 9700
- Thermaltake - BT
These are not the only ones that are good. I is merely a guideline. Take a look at the specs, in particular the material used, the surface area of the material and the cfm that compatible fans will yield. You will notice a trend.
Thermal management is a science, and one of the most pertinent factors being the ambient temperature.
Considerations for your choce:
- Do you have the space inside your case for a tower?
- Using coolers that are compatible with a 120mm fan are most effective
- Surface area of the cooler itself.
- HS material used
When reading our answers bear in mind that we all live in different climates. Ambient temperatures and humidty play an integral part in the air-cooling of your rig, and how well you will be able to shed heat.
Also, the level of your OC/and the Vcore applied will play a significant role.
Hope that this helps you arrive at a happy decision.
