Video Card  ATI Radeon HD 5450 512MB GDDR2  


Here is something I would not normally expect from just replacing two 120mm fans but I saw some decent numbers from these fans, I’m going to show you the different temperature readings from before and after installing Zalman’s ZM-F4 135mm Fans, along with Stock and OverClocked performance.


Here you can really see how much a difference these fans helped, the numbers might be small on the stock graph but you can defiantly see a good 5°C drop on load temps, which I couldn’t be happy with the results. Just think a 5°C drop by replacing 2 – 120mm fans, not bad Zalman!

 Before:  Using 2 – 120mm Cooler Master Fans @ 100%
 After:  Using 2 – Zalman ZM-F4 Fans 100%: RPM @ highest output 50%: RPM half output.

The graphs shown here have variables with room temp and other various things that could make temperatures higher or lower, all tests were based on 5 minute load times and 10 minute cool downs.
