Well now we know upgrading to a 140mm fan ca really improve the performance. I feel the design of the top down cooler does have useful advantages as well, especially with the resent stories of overheating and catching fire VRMs and hot running memory.

The quality of the SF524 is excellent though and it’s really well put together. The tightness of the fan screws could do with looking at but it’s easily fixed.

I see the cooler retailing for between £35 and £40. That seems like a good price for the solid build that you get here. I’d be happy to recommend it, though there are a couple of improvements that could be made.


Performed well at stock frequency
Quiet for most purposes
High quality thermal paste
Overall quality of the product is excellent
