Selling on the market for approximately $35 at press time, I find the SilenX Effizio EFZ-120HA5 to be decently priced against its competition in the given market niche for a quiet heatsink. Compared to the Arctic Cooling Freezer 13 and Freezer 13 Pro, its idling results seem to be slightly better, but under load conditions, it missed the mark by 5c, which is quite significant. But whether the slight difference in temperature in conjunction for the small difference in price really worth it is up to you, the SilenX Effizio EFZ-120HA5 is definitely a heatsink optimized for silence -- and you will have to sacrifice some performance for that. Its simple looks certainly quite eye catching, and having a window in your case will definitely make this heatsink look nice. Unfortunately, good looks does not always mean great performance over time. Due to the way this heatsink is constructed, it will lose some performance as time progresses; this occurs when its components loosen up after many heating and cooling cycles. Installing the heatsink onto the mounting plate was quite simple, but keep in mind that this process is only optimal when the fan is removed. Generally speaking, the SilenX Effizio EFZ-120HA5 is quite a decent product for the silent PC market it resides in. In the long run, if SilenX were to brush up on the details -- such as improving overall long term quality, which in turn would lead to better performance -- then we will have an undeniable winner in our hands for people looking for a quiet cooler on a budget.
