Test System & Test Results
TweakTown uses a different method for testing CPU heatsinks which allows for an even playing field across all product tests. We feel that by using the same ambient temperature and strict lab-like testing procedures we are able to accurately compare one product to another. More information on our testing procedure can be found in the T.E.C.C. article here.
The idle temperature of the EFZ-120HA4 is almost five degrees off the leader here, but stands well against most of the competition. Considering most of the ones listed above, the SilenX as you will soon see does it with a lot less noise.
At full load with the T.E.C.C. at the top end setting and the fan at full speed, the SilenX is still holding its own. Nothing overly special at this point, but make sure you see the next two charts!
Here is where the SilenX EFZ-120HA4 comes into its own. This is the most silent cooling solution I have yet to test. Granted, this is only idle testing, but the fan is just slightly audible at near 800 RPM.
At full load, the EFZ-12025-HSF is very impressive. While the temperatures were more average in the listings, at 2000 RPM I was shocked at the silence. With all of this info in mind, this is a very good cooling solution for those who don't tolerate loud fans.
