SilenX Extreme Effizio Silent CPU Cooler Review
User Rating: / 4
Written by lotsaentertainment   
Hits smaller text tool iconmedium text tool iconlarger text tool icon we will be taking a look at the SilenX Extreme Effizio Silent CPU Cooler. At first I was a bit skeptical looking at this cooler; it seemed as though it was very basic and, really, the only interesting feature was the 5 cooling pipes. I didn’t think it was going to be as quiet as it was, if you’re like me and really don’t get decibel ratings, just blow softly out of your mouth and that’s about what you’ll hear from this cooler. When taking a closer look we saw this was no basic cooler, this thing beat out all other coolers in its price range not to mention how quiet it was. Overall this is a great cooler no matter what you’re doing; whether it be overclocking, gaming, video editing, or just a PC enthusiast. So let’s get right in and do some testing.

Also, the Effizio also comes with a three year warranty.

I am going to be running my tests at an ambient room temperature of 20°C. I will be running both a load and idle test for each cooler. The Effizio will be going up against the Akasa Nero S.

Overall, I was quite happy with the SilenX Extreme Effizio CPU Cooler’s performance. It performed much better than the Nero S. For a budget PC enthusiast I would say this cooler is a great choice. Although, if you are a die-hard overclocker or someone who really pushes their computer past the limits, I would not recommend this cooler. Only because it is more for the consumer buyer and not for the big league computer expert.

Would I recommend this product? Yes, so far this is the very first SilenX cooler we have seen and it has been great.  The performance it displays in cooling make it a great choice for most gamers and enthusiasts.
