ARCTIC Freezer i30 Extreme CPU Cooler - Intel 320W Ultimate Cooling Power Direct-Touch Heatpipes
The Freezer i30 heatsink consists of 4 double-sided direct touch heatpipes 8mm in diameter
A patented process 20 2011 000 718 allows us to pack the heatpipes without gaps and thus increase the contact surface and achieve better flatness by precision machining - both leading to an improved heat transfer
As a combined result of the 4 direct touch heatpipes 48 Aluminum fins an interchangeable 120 mm PWM Fan ARCTIC F12 PWM and the famous ARCTIC MX-4 thermal compound included
The Freezer i30 offers superior cooling performance with a maximum cooling capacity of 320 Watts and lots of headroom for overclocking
Due to the low-noise impeller of the ARCTIC F12 PWM fan and the rubber vibration absorbers the Freezer i30 generates a negligible noise level of only 03 Sone even at full speed 1350 RPM
Furthermore as controlled by PWM signal this fan runs only at the optimized speed based on actual needs which in turns minimizes the noise level further
